> I always wondered, ever since I took that burden, that curse, I wondered what it could be what -- what my true happiness could even look like. I never found an answer. Because the one thing I want... it's something I know I can't have. But I think I know -- I think I know now. Happiness isn't in the having. It's in just being. It's in just saying it. (...) I know. I know how you see yourself, Dean. You see yourself the same way our enemies see you. You're destructive and you're angry and you're broken. You're -- You're "Daddy's Blunt Instrument." And you think that hate and anger that's -- that's what drives you. That's who you are. It's not. And everyone who knows you sees it. Everything you have ever done, the good and the bad you have done for love. You raised your little brother for love. You fought for this whole world for love. That is who you are. You're the most caring man on Earth. You are the most selfless, loving human being I will ever know. You know, ever since we met, ever since I pulled you out of Hell, knowing you has changed me. Because you cared, I cared. I cared about you. I cared about Sam. I cared about Jack. I cared about the whole world because of you. You changed me, Dean. (...) Because it is. I love you. (...) Goodbye, Dean.

> Castiel's last words to Dean, *Despair*

**Castiel**, often shortened to **Cass**, is a powerful angel of the Lord who was responsible for saving Dean Winchester from Hell, on the archangels' command. It was his job to help prevent Lilith from breaking the 66 Seals that, once broken, would release Lucifer from his cage in Hell. Once Castiel learned that the angels wished to free Lucifer anyway, he defied his angelic brethren and died trying to help Dean prevent Sam Winchester from breaking the last seal.

After he was killed by the Archangel Raphael, Castiel was resurrected by God and joined Sam, Dean, and Bobby Singer in a quest to prevent the brothers from becoming the vessels of Michael and Lucifer. Castiel would later be killed by Lucifer but his actions allowed Sam to trap both Archangels away. With the Apocalypse averted, Castiel was again resurrected by God with new powers, being promoted to Seraph. He then started a civil war in Heaven to prevent Raphael from restarting the Apocalypse, Believing he could not be outsmarted by a demon, Castiel teamed up with Crowley to claim the souls of Purgatory. He ended up betraying Crowley and absorbing all the souls, resulting in his powers reaching a level much higher than that of an archangel, but at a high price: the powers that the evil souls granted him had went to Castiel's head, causing him to proclaim himself as the new God.

As his body started to rot, Castiel later agreed on the advice of Dean to release the souls back into Purgatory. While seemingly successful, it turned out that the one of the most powerful entities from Purgatory, the Leviathans, held on to Castiel, and overpowered and took control of him. When the Leviathans left to take over new forms, Castiel was presumed dead, but survived – apparently resurrected by God yet again. Dean later accidentally finds Castiel as an amnesiac healer called Emmanuel. After taking on Sam's madness and experience in Hell in order to save the Winchesters and redeem himself for what he did to Sam, Castiel had become insane and fell into a coma. However, he awakens and his sanity is returned to an extent when a signal was sent to all angels upon the discovery of the Word of God and the appointment of a new prophet. He then aids the Winchester brothers against Dick Roman, only to be transported to Purgatory with Dean.

While Dean comes back, Castiel has not returned with him. While his condition is initially unknown, it's revealed that he spent most of his time running from Leviathans and that he didn't escape Purgatory with Dean as he had planned to stay as a form of penance. However, he was eventually released from the monster realm by an incursion of angels under the orders of a mysterious but powerful angel named Naomi, rejoining the Winchester brothers and trying to become a hunter himself. But after a long while, Castiel learned that Naomi had been controlling him ever since she got him out of Purgatory and compelling him to find the angel tablet, at any cost, even going as far as killing Dean. After he almost did so, Castiel then teamed up with Metatron when the angel convinced him to help him close the gates of Heaven. So after collecting the heart of a nephilim and the bow of cupid, Metatron is eventually captured by Naomi but escapes and kills her, only for Cass to discover Metatron's betrayal and plan to cause all angels in Heaven, even the imprisoned ones, to fall to Earth.

After being stripped of his grace by Metatron in order to expel all angels from Heaven, Castiel spends the next three months on Earth as a human. After being captured and tortured by an angel named Malachi, Castiel steals the grace of Theo and returns to his original status as an angel (previously being promoted to a Seraph). Castiel later assists Dean with expelling the angel Gadreel from Sam and heals Sam's wounds. After Dean leaves with Crowley to find a way to defeat Abaddon, Castiel also leaves to begin a search for Metatron and Gadreel while being pursued by other angels, and eventually killing rebel leader Bartholomew, he assumes command of his faction. However, a deception of Metatron's makes him lose his army; instead he teams up with angels Gadreel and Hannah to infiltrate Heaven and destroy the angel tablet, cutting off Metatron's power to allow Dean to kill him. Though successful, Dean and Gadreel are killed, while Castiel locks Metatron up. He then left Heaven as he didn't want to be a leader and was dying due to his burning-out grace before Crowley saved him with Adina's grace. He has since reclaimed the last of his own grace and restored to full power and being a Seraph once again.

After the release of the Darkness and the trauma he suffered under Rowena MacLeod's spell, Castiel agreed to act as the vessel for Lucifer to walk the Earth once more so Lucifer could battle the Darkness. Castiel would remain Lucifer's vessel for months, only emerging briefly to save Sam's life and convince the angels to help against the Darkness. At the end of the conflict with the Darkness, Lucifer was exorcised from Castiel by the ancient being, leaving Castiel in control of himself once more. During this time, he finally found God, who returned to defeat the Darkness as well.

After Lucifer was exorcised from him, Castiel would dedicate himself to finding the fallen archangel and locking him away, blaming himself for Lucifer being free upon the Earth once more. This task caused Castiel to reluctantly work closely with Crowley, who also desired Lucifer gone. Following Lucifer's apparent defeat, Castiel dedicated himself to hunting down Lucifer's son Jack, a dangerous Nephilim. After a battle with Dagon that resulted in Castiel's brief empowerment by the Nephilim fetus, Castiel became convinced of the child's supposed goodness and chose to become his protector and guide, forsaking the Winchesters in the process. While trying to lock Lucifer in an alternate reality, Castiel was killed once more by the Fallen archangel.

Following his death, Castiel was then sent to The Empty, where all angels and demons go when they die, to sleep for eternity. He was awoken from his eternal slumber when Lucifer's son Jack called his name. He was soon expelled from The Empty by the realm's guardian, The Shadow, for interfering with the latter's slumber, refusing to sleep again, and demanding his release, allowing him to be resurrected as a result. Castiel soon reunited with the Winchesters and Jack to help them out in their hunter cases. He later met with Lucifer who returned from the other world and warned him about the invading Alternate Michael. While in debate over recruiting Jack, Castiel and Lucifer were captured by Asmodeus, with Castiel being used as bargaining chip for the Winchesters. Castiel escaped and was betrayed by Lucifer who nearly killed him but he retaliated before the latter fled and Castiel returned to Sam and Dean to warn them about the impending threat. Castiel was also reunited with his brother Gabriel who wanted no part in the conflict as Castiel set out to locate him to get him to help in restoring Heaven. Very soon, Gabriel joins the team and after they capture Lucifer. They later travel to the Apocalypse World, and find Jack and Mary. The group is also aided by Lucifer after he escaped and decided to help out. Castiel evacuated with the others back to Earth but at the cost of Gabriel. They faced a new problem as Michael made his way there and Castiel finally met his enemy who tossed them aside. Jack wounds Michael, but then has his grace stolen by Lucifer. So Dean agrees to be Michael's vessel and kills Lucifer, at the cost of losing control of his body.

At the beginning of season 14, Castiel is committed to finding Dean, who was possessed by Michael and disappeared after defeating Lucifer. He resorts to a demon, Kipling, who lures him into an ambush and uses Castiel as a bargaining chip to meet Sam and get his support to become King of Hell. Together, however, Sam and Castiel defeat Kipling and his henchmen. Dean is found, in full possession of his conscience and with no sign of Michael. Jack, however, begins to decline in health, having lost his grace earlier, and then dies. The Winchesters seek Lily Sunder to help resurrect Jack, and Castiel goes to heaven to find his spirit and bring him back to his body. Heaven, then, falls under attack from the Shadow, who wants to take Jack to the Empty. In order to stop him, however, Castiel convinces the Shadow to take him in exchange for Jack; the Shadow agrees, but says that he will not take Castiel's life until much later, when the angel will have forgotten their conversation and experienced a moment of happiness. Jack is resurrected and, with the help of Sunder's magic, he defeats Michael and consumes his grace, thus regaining his powers; during the battle, however, he had to burn out what was left of his human spirit, getting in a state similar to that of soulless humans, amoral and without emotions. In that state, he kills Mary Winchester, causing Dean to turn against Castiel, as the angel had hidden from him what'd happened to Jack. In the end, Chuck reappears and tries to manipulate the Winchesters and Castiel to kill Jack in a showdown at a cemetery, but the trio refuses, causing Chuck to personally smite Jack and Team Free Will to then attack him. Furious, Chuck opens up all closed doors of hell and lifts undead corpses from their resting ground, thereby causing the second apocalypse.

The Winchesters and Castiel try to stand their ground against the zombies awakened by Chuck. They receive unexpected help from Belphegor, a heretofore unknown demon who, to Castiel's chagrin, is possessing Jack's dead body. To stop the ghosts from leaving the tear that Chuck opened on the surface of Earth, which leads to hell, and neutralize those who already made their departure, Rowena joins the group to perform a *Book of the Damned* spell, while Castiel and Belphegor descend to hell in search for Lilith's Crook, an instrument manufactured by the white-eyed demon that can suck in demons and ghosts who try to escape hell in disobedience. Castiel, who is suspicious of the demon, initially refuses to escort him back to hell, but is forced to do so by Dean, who still resents the angel and doesn't want him around. Castiel discovers Belphegor wanted his company so that he could read the Enochian incantation that can open the Crook's box, and that his plan all along was to use the object to absorb the spirits of hell into himself, become more powerful, and take over hell's throne. Castiel throws himself at Belphegor while he plays the instrument, smiting him so badly that Jack's corpse is burned to a crisp and the Crook is destroyed. Castiel manages to return to the surface of the Earth, and he tells Dean he couldn't let Belphegor fulfill the plan to suck in all of hell's souls, enraging Dean - against his friend. Since the Crook is gone, Rowena decides to cast a spell so that she can herself absorb the spirits inside her own body, dying in the process. The death of their witch ally further intensifies Dean's anger at Castiel, and in an argument at the bunker he throws in the angel's face that everything that goes wrong in the group's endeavors has been Castiel's fault. Tired of weathering the storm of his friend's moods, Castiel says that he is dead in Dean's eyes and so it is best that he move on without the Winchesters. Later, he ignores Sam, who tries to contact him via phone messages. Castiel subsequently returned to the brothers to help them defeat God by grooming a resurrected Jack to become stronger. After the plan fails and they are chased by Billie, Castiel sacrifices him by confessing his love for his close friend and allows himself to be happy. This activates his deal with the Shadow who drags him and Billie into the Empty.

He is later resurrected again by Jack after he becomes the new God, as Bobby Singer tells Dean that Castiel helped Jack to reshape Heaven for the better.

Castiel's legacy has seemed to have become legendary among angels and demons alike, as many recognize him as the only angel who defied God's rules and cooperated with humans due to his own decision, which he is either loathed or respected for. He is also the only angel to have been killed, and been resurrected multiple times. He is the only known angel who has repeatedly been resurrected by God so he could help Sam and Dean Winchester.

1/4
As an angel, experiencing Castiel's true form will result in blindness, deafness, or even death, as the appearance of his natural visage is so overwhelming that it is capable of burning human or demon eyes from their sockets (as seen in *Lazarus Rising*), as he said to Dean, "*My true form. It can be overwhelming to humans and so can my real voice.*" However, Castiel stated certain, "special people" are able to tolerate his true appearance and voice. Although his true form has never been seen, it is known that he has two feathered wings. When Castiel becomes a seraph, he describes himself to Samuel Campbell as a *"multidimensional wavelength of celestial intent"* and his true form is "*approximately the size of your Chrysler Building*" in height. As he was promoted to a seraph, it stands to reason his true form has changed to one of a seraph's. It is presumed to be very tremendous and terrifying, as the mere image of it was enough to cause Crowley to flee in fear of being smited. In addition, Castiel has been referred to as being attractive on more than one occasion, both in his human vessel and his true angelic form. One female demon, while talking with Crowley, once instantly said Castiel was, as she said in her words, hot, as she also said, "*I mean, human Castiel? eh. But, feathered Castiel? Phew.*" The same demon even once called him "*Captain Sexy.*" Another instance was a woman who referred to him as "*young and sexy*" while he was god and had recently killed a pastor at the church she attended. Since having his grace removed for Metatron's spell, Castiel has lost his wings, even with Theo and Adina's grace. Though he has since regained the remnants of his grace and been restored to full power, his wings are broken.

 File:Castiel 807.jpg
For humans, they see him as the appearance of his vessel, Jimmy Novak, who is a handsome man of average height in his thirties. He sports a pair of dress shoes, a black suit, a buttoned white-striped dress shirt, and loosened blue necktie accentuated by a beige trench coat. Although he has a very dire demeanor, his outward appearance radiates a natural calm and serenity which makes conversation easy and direct. Since his third resurrection, his appearance has changed. He lost his trench coat upon his third death and when he became amnesic, he wore different clothes. Upon regaining his memories, Dean gave him back his trench coat, but he still wore Emmanuel's clothes until he became insane. While insane he wore his trench coat and hospital scrubs. While in Purgatory he retained the same outfit, albeit extremely dirty and torn off. Castiel also grew a beard and his hair became messier. After returning from the monster realm, Castiel returned to his original appearance. He kept this until he lost his grace and became human. While he initially kept his usual clothes, they became dirty and he was unable to clean them and get food and water so he abandoned the trench coat and suit and took to wearing more casual human clothes, though he did wear a suit when he pretended to be an FBI agent. After becoming an angel again, Castiel donned a new suit and trench coat, albeit not as accented as his previous trench, nor as long. He at first didn't wear a tie like before, but after a suggestion from Claire Novak that he looked better in a tie, Castiel donned the blue striped tie from his FBI suit and continued to wear it in the next seasons.

As of Season 13, Castiel returns to his classic attire of seasons 4-8 with a new black suit, and trench coat. His tie is once again a single shade of blue.

In 1901, Castiel possessed a female vessel and dressed as a woman from that era. Notably, he wore a coat very similar to the trench coat he wore in his first appearance. It is safe to say that, like most angels, Castiel does prefer to retain his vessel's original appearance and clothing. He does not seem to have a high fashion sense, preferring neatness over beauty.

## Personality

 File:FullSizeRender-12.jpg
Castiel is a strong, determined, impulsive, competitive and naïve celestial being. Like most angels, Castiel expresses little to no emotion, which creates flaws and complexities in his persona. Despite this, he does not display the blank apathy or mocking superiority that seem to characterize angels such as Uriel or Lucifer. His lack of emotion and understanding of human behavior such as sarcasm has led to several humorous situations throughout the show, and has occasionally gotten him into trouble with humans, ultimately leaving Dean or Sam to amend the situation. He does, however, become close friends with the brothers, who encourage him to be kinder, more caring and more selfless.

Unlike some of his brethren, Castiel still has faith in God, though not to the zealot-like extent displayed by Michael. While he admits he may not always understand what God wants and may question his reasoning, Castiel always follows his father to the best of his abilities. This, along with his interest in humans, has caused other angels to label him as weak or naïve, but also peculiar. Anna Milton and Lucifer have both displayed this attitude, with Anna calling him a hypocrite for refusing to rebel in order to gain more freedom. Castiel briefly loses this faith after Joshua reveals that God doesn't care and falls into a depression for some time. However, when God resurrects him for a second time, his faith returns. Castiel frequently exhibits what could be referred to as affection towards Dean, and seems to express regret, hesitance, and anger at several points.

Being around the Winchesters, paired with his experiences in the War, have taught Castiel several "tricks" that have helped him during the show. While not possessing free will in the same sense as a human, Castiel has learned how to bend the rules at times, like in season 4. The best example is when he informs Dean about Chuck's archangel, thereby giving Dean the idea to use him to save Sam from Lilith (*The Monster at the End of This Book*). He was also able to distract Meg long enough to use her. This was similar to a trick Uriel performed to free Alastair, Castiel used Meg for his trick to free himself, from a ring of holy fire (*Abandon All Hope*). It is also possible he learned from the demon Crowley to wipe out loyalists of his adversary, Raphael. Castiel also considers himself to be the Winchester's personal guardian angel.

When Castiel is brought back from the dead after Lucifer kills him, his personality begins to shift. During Season 6, Castiel becomes more prideful. It is because of this pride that Castiel makes a deal with Crowley, and starts the civil war in heaven. During this time Castiel showed extremely high ambition, doing everything he could to open the door of Purgatory. He also displayed his intelligence, being capable of tricking Dean, Sam, Raphael, and even Crowley (well known as a crafty trickster.)

Upon absorbing the souls, Castiel's hubris grew to the extent that he claimed to be the new God. It was later revealed that others, such as Death, thought of him only as a mutated angel. Previously acting kind, assuring, and fierce at times, Castiel had now become almost purely cold and absolute in his decisions. This is displayed when he kills Raphael without any second thoughts. Mere seconds later, he demanded that Dean, Bobby, and Sam kneel before him and be by his side. Castiel claimed he would destroy them if they forgot their place and rose up against him. However, he still had some lingering affection for them, trusting them enough to leave them alone. They soon realized that he was out of control and that being influenced by the Leviathans. Later, when Castiel returns to his original personality, he feels incredibly guilty and goes back to his friends for help. Knowing Dean is furious with him for breaking Sam's wall, Castiel expresses true remorse for his actions and swears to do all he can to make up for what he did.

After his third resurrection, Castiel lost his memories and took on a more human personality, though he was still more distant than normal humans. He expressed affection for his wife Daphne Allen, and retained his desire to help people as shown by the fact that when he rediscovered his healing powers, he used them to heal people in need, also showing great compassion. While shocked by the existence of demons, he took it relatively well once it was explained to him. He was perceptive enough to realize that Dean couldn't forgive "Cass" for what he had done and felt betrayed and that he himself was the Cass mentioned after overhearing some of Dean's conversation with Meg. In his human mindset, he had no idea of what he was capable of and was nervous with the idea of using his powers to kill demons when he had no idea how. However, despite this, he displayed courage in agreeing to try and seemed to still possess an instinctual knowledge of how to use them as he quickly figured out what to do.

After recovering his memories, Castiel's normal personality more or less returned, and he was overcome with guilt over what he had done, how many he had killed, and for releasing the Leviathans, even questioning why he was still alive. Following his awakening, his personality was greatly modified, due to a combination of what he had taken from Sam and his own guilt. It made him inattentive, overly calm, uncaring and seemingly dim. He also became a pacifist, and refused to fight, even when being attacked, as well as being overly optimistic, perceiving many negative things in a positive way. During this time he developed a unique relationship with Meg, a demon, as she was his caretaker during his insanity. He showed open attraction to her, calling her a "thorny beauty". Although Meg doesn't return the feelings at the start, a year later she openly flirts with Castiel, and Castiel seemingly returns the attraction. In *Survival of the Fittest*, Castiel explains that his pacifism comes from being afraid of causing more damage with his actions. However, he agrees to break his pacifism and help stop the Leviathans, possibly out of loyalty to Dean as he agrees after Dean says he'll likely die trying to stop them. After agreeing, he doesn't hesitate to fight, helping to dispatch Royce and getting in front of Dean to protect him from Dick Roman and later restraining the Leviathan leader so Dean can kill him. Castiel also displays a bleak view on his resurrections: instead of believing it to be a gift from God for his service, he now sees his resurrections as punishment for his actions, telling Dean "I see now it's a punishment resurrection, it gets worse every time."

After he and Dean were sent to Purgatory, his sanity and original personality was restored, although he himself states nobody could ever be sure if he is indeed sane. Following his return in *A Little Slice of Kevin*, Castiel displayed a slightly more laid-back personality and a much less detached persona and showed human emotions as well as a taste for human things, as he commented how he missed watching TV. He has also developed a strong desire for penitence, looking for anyway possible to redeem himself for the devastation he caused Heaven and his fellow angels.

Since becoming human briefly, Castiel has become more human. He expresses more of an appreciation for human things and develops more human emotions such as romantic attraction. He also became less serious, drinking a beer with Sam and Dean and joking around. He proved to be good enough at being human that he was able to fool law enforcement and pose as an FBI agent, something he could never do successfully before even with coaching from Dean. Even after becoming an angel again, Castiel hasn't seemed to lose his human emotions, getting very angry when he realized who Gadreel was and freely expressing it and comforting a distraught Dean, understanding why he was so upset rather than being confused as he would have been in the past. While briefly human, he was ready to embrace his new status, excited to have Sam and Dean as his teachers and seemed to see his return to being an angel as a necessary evil more than something he wanted and called his stealing of the grace of Theo as barbaric and something that made him as bad as the other angels. Castiel also seems to now understand human ways better, able to drive and steal a car, a skill he never previously showed, though he still lacks full knowledge of everything as he didn't know to get gas. He also developed a taste for human food, something that was made harder by the return of his angel powers and completely lost any former disgust he had towards Sam, finally understanding why he'd done everything he did. Castiel also learned that the ends don't justify the means when it means sacrificing lives. Thanks to Metatron, Castiel has also finally gained the ability to understand Dean's constant movie and TV show references, something that had previously frustrated him into always saying "I don't understand that reference." This helps him now understand human culture better.

Castiel seems to have a fondness for his usual appearance as he never changed until he briefly believed he was human. At first he may not have changed out of lack of necessity, but after returning from Purgatory, he put back on his usual outfit and was very pleased to be able to do so. He seemed to be particularly fond of his trenchcoat as even insane he wore it and was seen to only reluctantly let it go when as a human he was unable to afford to cleaning it. After becoming an angel again, he donned a new trenchcoat and suit, once again displaying his fondness for that particular attire.

In the aftermath of being put under the Attack Dog Spell by the witch Rowena, it, according to Metatron, made Castiel broken and paralyzed due to the trauma and due to him attacking other people, including Dean. Even after Castiel was free from the spell, it still has also apparently "scarred" Castiel so deep that Cass wouldn't even leave the bunker. Even Metatron, who is now human, noticed it especially when he said Castiel couldn't even hit him. However, while he misjudged it as Castiel being afraid, after being hit and thrown by Castiel multiple times, Metatron then realized that Cass is not scared, but is actually angry instead about, as Metatron said, "*being everyone's tool. Manipulated and used by the angels, by your enemies, by your friends.*" Even Castiel himself said that he is tired of having his strings pulled.

Castiel eventually allowed Lucifer to possess him in order to be useful to the fight with Amara, seeming to see himself as useless now. Castiel only fought Lucifer once to protect Sam, but was unable and unwilling to expel Lucifer from his body. When Crowley entered Castiel to get him to expel Lucifer, Castiel was shown to have become apathetic to the whole situation and intended to just wait the fight out, not intervening even when Crowley and Lucifer fought it out in his mind and simply scolding them for bothering him. Crowley believed that Lucifer did something to Castiel to cause this, that Lucifer "got his hooks in good." When given control by Lucifer to speak to the angels, Castiel displayed his regular personality rather than the one Crowley saw in his mind and stated that he truly believed his role in the upcoming fight was to give Lucifer form on Earth so he could aid God in defeating the Darkness. After Lucifer is expelled from Castiel by Amara, Castiel seems to return to his old self completely with the archangel's influence gone from his mind, but continues to believe he did the right thing by consenting to Lucifer's possession.

Now free from an impending war, Castiel seeks to capture Lucifer for he believes himself to be responsible for letting the archangel out, going so far as to decline help from Sam and Dean but accepting Crowley's simply because the demon proves useful, though Castiel repeatedly expresses dislike in having to work with Crowley, calling the situation "unfortunate". Unusual for his character, Castiel has begun using sarcasm and now throws around witty retorts, most notably at Dean. However, it should be noted that Castiel continues to feel out of place and in a desperate need to prove himself.

As noted by Uriel, Naomi, Metatron and Ishim, Castiel is very attached to his ward, Dean Winchester, though he has come to include Sam and Mary as people in his care, and despite accusations that these three humans make him weak, Castiel defends that they are the source of his strength. His determination to keep them alive has led him to murder Billie despite the consequences, proving that Castiel will put his own well being below theirs. He has also chosen to trust them more than his angelic siblings, given their history of deceiving Castiel and their very contrasting beliefs. Most remarkably, Castiel continues to be a forgiving, loving and gentle angel whenever he can. His current desire to undo his past sins and mistakes has compelled him to make a change.

## Trivia

* Castiel has killed one main antagonist, Raphael in season 6, and has defeated a main antagonist, Metatron in season 9. He has also defeated one secondary antagonist, Pestilence in season 5, and killed a secondary antagonist, Bartholomew in season 9. He played a major role in killing another main antagonist when he helped Dean kill Dick Roman in season 7, which sent both Dean and him to purgatory. He later killed the secondary antagonist Belphegor in season 15 and was directly responsible for the death of the secondary antagonist Billie in the same season.
* Castiel can be seen as the main antagonist of season 6 along with Raphael and Crowley, though some argue him to be more of an anti-hero in that season.
* Castiel's name is considered a variant of the name "Cassiel", who in angelology, is the angel of Thursday with his month being November. This name was possibly chosen for the character in *Supernatural* because the show (then) aired on Thursday nights.
	+ Funnily enough, God mentions Castiel as being the self-hating angel of Thursday in the episode *Unity*
* Jim Michaels jokingly tweeted that Castiel's nickname is spelled as **Kaz**.
* He is among the most popular characters of the show; in fact, he was spared from the writers' original plans of being permanently killed off at least twice - in *On The Head Of A Pin* and *Swan Song* for this very reason. The actor who performs his role, Misha Collins, was promoted to regular status in Seasons 5, 6 and 9, which only two other actors, Katie Cassidy and Lauren Cohan, had previously held. Collins has also been the only other actor than Jared Padalecki and Jensen Ackles (Sam and Dean's actors) to be included in the group seasonal promotional pictures until Season 8, which also includes Crowley.
	+ A third attempt to kill Castiel off occurred in Season 7, but that, too, had to be undone.
* Castiel is the most recurring angel in the series, despite only having a six-episode story arc in the original planning; his appearances have surpassed even Bobby Singer's.
* Season 4 is the only season Castiel appears in where he doesn't kill another angel.
* Castiel has killed every species of angels except for the Cherubim and Seraphim.
* Co-star Jared Padalecki does not believe *Supernatural* can exist without Misha or Castiel.
* Because he believed his character's tenure on the show would be short, actor Misha Collins used a deep, gravelly voice while portraying his character that he believed fit Castiel's introduction as a powerful entity. He later came to regret this choice when Castiel became a recurring character, as the voice Collins used for Castiel hurt his throat. In their scenes on-set together, he and Ackles reportedly compete with one another in who can use a deeper voice.
* Mark Pellegrino, who played Lucifer, originally auditioned for the role of Castiel.
* Despite being the one to confirm the existence of angels to Sam and Dean, he is the second angel to be revealed in the series as Gabriel has the distinction of being the first one to appear.
* Castiel is known to have used three vessels: an unnamed woman in the 19th-century, Jimmy Novak, and his daughter, Claire Novak. Castiel has revealed that he could also use Sam Winchester (and by extension, presumably Dean Winchester too) if he had his permission.
* After becoming a "mutated angel" by absorbing all of Purgatory's souls, the wing flapping sound is no longer heard when Castiel teleports, insinuating that it affected his true form.
* Upon shifting Sam's condition onto himself, after he awakes, in his insanity he becomes obsessed with bees. In *There Will Be Blood*, he admits to wanting to watch them. In *Survival of the Fittest* Dean mentions he once appeared on the Impala naked and covered in bees. In the same episode, Castiel offers Crowley honey.
* Despite the Leviathans' ability to kill angels easily, Castiel is one of the few beings that has been able to hold his own for at least a short time against them, sharing this with Sam, Dean, and the Alpha Vampire. This may be because he is a Seraph, a stronger class of angel than the ones that previously faced the Leviathans. Castiel was able to single-handedly hold his own against two Leviathans in Purgatory until Dean was able to decapitate them. However, he is unable to defeat them on his own and has been nearly killed by Leviathans in Purgatory on at least two occasions. He did however partake in killing Dick Roman in a team effort with Dean.
* Castiel, like all members of Team Free Will, has been to Hell, Purgatory and Heaven. Only Dean has been to Avalon in addition to the three previously mentioned. However, Castiel (along with Jack) has, due to the natural order of death for angels, been to the Empty.
* Before losing his grace, Castiel was the only known Seraph in *Supernatural*. He lost this power when Metatron stole his grace. He eventually regained angel powers with Theo and later Adina's grace and became a Seraph again when he regained what was left of his own grace.
* At some point Castiel learned how to steal and drive a car. As he can no longer teleport without his wings, he stole a car in *Road Trip* to reach Dean. Ironically the car color matches his first trench coat, which explains why he liked it. However, the first time Castiel is seen driving on-screen is in the episode *Meta Fiction*.
	+ In Season 12, Castiel has begun using a truck that he stole instead of his signature car.
	+ Following his resurrection in Season 13, Castiel begins driving a series of different vehicles instead of just one consistent car or truck, though he does have a truck that he uses for several episodes before it disappears again.
* After years of being frustrated by Dean's repeated references to movies or TV shows, Castiel has finally gained an understanding of them in *Meta Fiction,* thanks to Metatron granting all his pop culture knowledge into Castiel's brain. Before this, his default response was to say "I don't understand that reference" and he shocked Sam and Dean by understanding a *Star Wars* reference when he displayed his new knowledge.
	+ In an ironic twist, Castiel makes a *Star Wars* reference to Gadreel in *Do You Believe In Miracles?* and Gadreel doesn't understand the reference. Usually it's the other way around; someone makes a reference to Castiel and *he* doesn't understand it.
* During his time in Purgatory, Castiel sported a beard, though his facial hair never changed on Earth. He shaved it off after returning to Earth.
* Castiel's signature trench coat look was homage to the anti-hero con man magician, John Constantine of the DC/Vertigo comics. Eric Kripke stated that he had originally wanted John to be a recurring character in the Supernatural series, but was told no. Instead, Kripke created Castiel and dressed him in a trench coat as homage.
* It is confirmed that Castiel's vessel Jimmy Novak is in fact dead, making Castiel the only known angel possessing a dead body due to the angelic need for permission. Michael became the second Angel and only Archangel to possess a dead body as his vessel in *Inherit the Earth*.
	+ Castiel has also begun to refer to the corpse as "*his* body" rather than "*his* vessel".
	+ Also, due to losing his grace and becoming a human while in this body, the body became effectively his; even after he regained his grace and became an angel again, he retained the ability to give permission to other angels to possess his body.
* In the episode *Red Sky at Morning*, one of the words Sam reads in the incantation to summon the ghost at the graveyard is the name "Castiel". This was in Season 3, before Castiel ever appeared.
* Castiel is the first angel to have his vessel possessed by another angel, while he himself is still inside of it. This occurred when he said "yes" to Lucifer.
* Like Sam, John and Bobby, Castiel has shown the ability to overpower a being possessing him. Castiel managed to overpower Lucifer briefly, but stated that it took all of his strength just to hold him back from killing Sam and could not eject him as a result. Unlike Sam, Castiel noticeably struggled with Lucifer for control while Sam was able to hold Lucifer back to the point he could move around and throw himself into the Cage.
* It is implied in *Don't Call Me Shurley* that God's favorite angel is Castiel, as pointed out by Metatron.
	+ Though in that same episode, while God confirms that he was the one who resurrected Castiel each time he died, it is implied that he is disappointed in him as he told Metatron "I rebuilt Castiel more times than I can remember and look where that got me!"
	+ As of Season 15, Castiel is likely no longer the favorite because of his attempts to help the Winchesters defeat him. Indeed in *Unity* God expressed anger towards Castiel and his rebelliousness.
* As pointed out by Sam, Castiel's vessel is very strong, having held the Seraph for years, and, at one point, withstanding a simultaneous possession by an Archangel and a powerful demon. Despite still being possessed by Lucifer, after a considerable length of time, it appears to be intact, as opposed to Lucifer's temporary vessel, which began to deteriorate almost immediately. Castiel's vessel also withstood millions of souls from Purgatory and many Leviathans for some time before it started to degrade. In *We Happy Few*, Castiel tells the angels that Lucifer possessing him is actually burning both him and his vessel out despite not showing visible damage, indicating that he is strong enough to last longer than a regular vessel.
* When going undercover as an FBI agent, Castiel has adopted Dean's habit of using pop culture references as his aliases. However, instead of classic rock, he uses pop stars, not seeming to see a difference when confronted by Dean when he dubs the Winchesters Agents Aguliar and Spears. Castiel has also used Agent Beyoncé in *The Foundry*, prompting Crowley to dub himself Agent Jay Z.
* Chronologically speaking, Castiel is the first angel to use vessels of both genders. In 1901, Castiel was shown to use a female vessel while working with Ishim. However, unlike the other members of Ishim's flight, Castiel did not keep this vessel for an unknown reason.
	+ Castiel is also the first angel shown on-screen to use both a male and female vessel. This happened when he briefly possessed Claire Novak in Season 4. This was followed by Raphael in Season 6 and Hannah in Season 10.
* Castiel sought to find God in Season 5 though had no luck and gave up his search. He eventually met him in *Alpha and Omega*.
	+ This makes him one of the seven angels to personally meet God though they had no known conversations on-screen.
	+ Coincidentally, he already met him in Season 4 but was unaware of his identity.
* In later seasons, Castiel uses his angel blade to kill demons rather than his smiting power, even after he becomes a Seraphim again. Until Season 13's *Various & Sundry Villains*, he hadn't used smiting since he smote Theo in Season 9's *Holy Terror*, a span of over four years. The last time he used smiting to kill a demon before *Various & Sundry Villains* was in Season 8's *Goodbye Stranger*. No explanation is ever given for Castiel's change in killing method, particularly after he gets his grace back and no longer has to worry about it being depleted.
* In *Scoobynatural*, Castiel implies he is now married to the Djinn Queen after getting the Fruit of the Tree of Life.
	+ This marks the first union between a monster and angel.
* He is the first character to kill an Alternate version of himself, since Kaia was revealed to have been saved by Dark Kaia, after Dark Kaia almost killed her by accident.
* As of *The Big Empty*, Castiel was the first being to escape The Empty.
	+ This was confirmed in *Byzantium*, when Naomi states that he is the only angel to ever escape from that place.
* In the Studio & Network draft of *Peace of Mind*, Castiel reveals he watches Riverdale, a fellow The CW show.
* As seen in *The Heroes' Journey*, Garth named one of his twin sons after Castiel. The baby appears to also have Castiel's tendency to give Dean weird stares.
* According to God in *Unity*, this version of Castiel is the only one that rebelled instead of doing what he was supposed to do after resurrecting Dean from Hell in Season 4.
* Misha Collins stated in a 2020 panel that Castiel's wings are rainbow.
* Castiel is canonically bisexual in the series. He was shown to be romantically interested in the demon Meg, had a sexual encounter with the reaper "April Kelly", and was attracted to the angel Hannah. In his "human" life as Emmanuel, he was also married to a woman. But he eventually confessed his love for Dean in the season fifteen episode *Despair*. The romantic nature of his feelings for Dean has been confirmed by Misha Collins, who described Castiel's final speech to Dean as a "homosexual declaration of love".
	+ In the Spanish dub of this episode Dean responds with a "y yo at ti" which was confirmed by Misha Collins to have not been in the original script, as many fans had speculated had been censored out.
	+ Castiel is thus the one main character and angel character in the series to be confirmed as LGBT+.

## History

### Early life

> You know, I've... I've been here for a very long time. And I remember many things. I remember being at a shoreline, watching a little gray fish heave itself up on the beach and an older brother saying, 'Don't step on that fish, Castiel. Big plans for that fish.' I remember the tower of Babel... all 37 feet of it, which I suppose was impressive at the time. And when it fell, they howled divine wrath. But come on. Dried dung can only be stacked so high. I remember Cain and Abel... David and Goliath... Sodom and Gomorrah.
>
> Castiel explaining his early life, The Man Who Would Be King

Although not much is known about Castiel's early life, as an angel, he has existed for millions, if not, billions of years. He watched as the first fish emerged from the ocean. Even Metatron hinted that Castiel has "*been around since scaly things crawled up out of the muck.*" Naomi also once said that Castiel has, as she put it, "*been unstable in the past.*" Additionally, discussions with Uriel suggest the pair were children by Angel standards when Lucifer rebelled against Heaven and refused to bow down to humanity. While his brother was enthralled by Lucifer's power and charisma, Castiel remembered being frightened and disturbed by the rebellious Archangel.

Castiel had been stationed on Earth for at least 2,000 years while being in the garrison commanded by Anna, who became very close to him, which also contained Uriel, Balthazar, Hester, Bartholomew, Ishim, and Benjamin. Castiel was present when the world was first created, making him over several thousands years old going by the biblically time (Uriel also made reference to questioning 'How long have I served' as '6 or 7 centuries'). He also witnessed Cain killing Abel. He also watched them build the Tower of Babel, David killing Goliath, the destruction of Sodom and Gomorrah, and among other historic and Biblical events. He also knew a Prophet named Luke that authored two books in the Bible. He also witnessed the evolutionary struggle between *Homo sapiens sapiens* and Neanderthals and was hoping that the latter would survive because of their superior poetry (though this particular opinion and reasoning may have just been madness).

### 20th Century

 File:Lily Sunder Has Some Regrets 004.png
In the 1900s, Castiel was a part of Ishim's flight and used a female vessel. In 1901 this flight of angels came to Earth to kill Akobel, an angel who had supposedly fathered a Nephilim with Lily Sunder. After Akobel was captured, Castiel listed his crimes before he was killed. Castiel and the rest of Ishim's flight then waited outside for Ishim to kill the Nephilim, unaware that he was using them to get revenge on Lily whom he was obsessed with and who didn't have a Nephilim daughter. Sometime after, Castiel joined another garrison, led by Anna Milton, whom Castiel had become close with. After her fall, Castiel became the garrison leader, which consisted of Uriel, Balthazar, and other angels.

### 21st Century

 File:Jimmy possessed.jpg
In 2008, Castiel spoke with his true vessel, Jimmy Novak, in Pontiac, Illinois. When Jimmy was watching television, Castiel's voice distorts the picture and caused him to scream in pain and his body to spasm until he finally blacked out. Later, Castiel told Jimmy to put his arm in boiling water and that he would be unharmed as a way to prove his faith. With his wife believing that he was going crazy, Jimmy asked Castiel what he wants from him and how he can help. Castiel explained that he needs to use Jimmy Novak as a vessel, to which Jimmy agreed to as long as his family is protected. After receiving consent, Castiel possessed Jimmy Novak. Before he left, Castiel was confronted by Jimmy's daughter, Claire, and told her that he is not her father.

### Season 4

> I am not here to perch on your shoulder. We had larger concerns.[...] We tried. And there are other battles, other seals. Some we'll win, some we'll lose. This one we lost. Our numbers are not unlimited. Six of my brothers died in the field this week. You think the armies of Heaven should just follow you around? There's a bigger picture here. You should show me some more respect. I dragged you out of Hell. I can throw you back in.

> Castiel to Dean, Are You There, God? It's Me, Dean Winchester

 File:Castiel shows his wings.png
When Dean Winchester broke the first of the 66 Seals that would allow Lucifer to walk free, the angels took action. They fought their way to Hell and Castiel freed Dean from the pit. Dean awoke in a grave and made his way to the surface, not knowing how he had been resurrected; the only clue he had was his healed body and a large imprint of a hand near his shoulder. Castiel attempted to speak with Dean in his true voice on two occasions but discovered Dean wasn't one of those who could understand him.

After reuniting with Bobby Singer and Sam, Dean tried to learn what had rescued him from Hell. He also discovered that he'd been dead and buried for four months. Dean's group met with Pamela Barnes, a psychic who gave them Castiel's name and tried to get his true visage though Castiel warned her to turn back but she didn't heed it and her eyes were burned, blinding her. Castiel also killed the demons in a diner Sam and Dean visited, one demon telling Sam its the end.

Eventually, Dean took matters into his own hands and with Bobby's help, set a trap for the creature and protected himself and Bobby with multiple Devil's Traps and other anti-demon devices. Castiel arrived and the hunters shot at him as he passed through the Devil's Traps with ease. Castiel identified himself as the one who saved Dean before he was stabbed by him with Ruby's knife but it had no effect and Castiel quickly knocked out Bobby with a mere touch. Castiel explained who he was to Dean, telling him "I'm an angel of the Lord". Dean didn't believe him, thinking there was no such thing as angels and Castiel criticizes his lack of faith before he reveals his Angel's Wings to prove his claims. Though surprised, Dean then brings up what Castiel did to Pamela as Castiel brings up he did warn her since his true form was overwhelming. He then tells Dean that his true voice was the same shriek Dean heard at the gas station and motel so he took on a vessel to better communicate. Dean then asks why he was saved as Castiel notes Dean didn't he deserved to be save before he tells him God has work for him.

 File:Castiels informs Dean about Lucifer and the 66 seals.png
After people who were supposed to be dead seemed to be rising from the grave, Castiel appeared to Dean in a dream and explained to him that this was one of the 66 Seals, "The Rising of the Witnesses." Castiel told him that Lilith was attempting to break 66 of the seals which would lead to Lucifer walking free on Earth and then the Apocalypse would begin. The Angels had been fighting to stop the demons, but the odds were against them. He explained to Dean that he must help stop the breaking of the seals as well. Castiel also showed that he was not a force to be underestimated or even taken lightly as in a chilling tone, he told Dean to start showing him some respect or he'd change his mind and throw him back into Hell again.

 File:Castiel and Dean in the past.png
One night when Dean was asleep, he woke up to find Castiel sitting beside him. Castiel, remarked on Dean's dreams, then without speaking further tapped Dean and brought him back in time to an important few-day period in 1973. It showed Dean the connection between Azazel and Mary Winchester, and answered questions that had always been on his mind. Castiel said that the reason he had brought Dean back to that period was to make sure that he was caught up with all of the facts. After Dean indirectly set the future in motion, Castiel appeared to take him back. Castiel explained that the angels are still unaware of Azazel's endgame. Castiel also told Dean about Sam's developing abilities and that he was going too far down a dark path and that if Sam did not stop using his powers, then the angels would kill him.

> Your brother is heading down a dangerous road, Dean. And we don't know where it leads. So stop it ... or we will.
>
> Castiel, In The Beginning

During *Metamorphosis*, Castiel is mentioned to Sam by Dean as the one who told him about his usage of his powers.

 File:Boysandangels.jpg
Sometime later, Castiel and his partner Uriel met with the Winchesters when they were in the middle of hunting a witch. Castiel met Sam for the first time, as the latter was excited to meet him. Castiel told Sam that he was happy that he stopped using his psychic powers. The angels explained that the witch was trying to summon the demon Samhain from Hell and that this was another one of the 66 Seals. The angels said that they would have to destroy the entire town and all of its residents to ensure that the seal would not be broken. The brothers argued against this and assured Castiel and Uriel that they could stop the witch from summoning Samhain. While Uriel wanted to smite the town anyway and drag Dean and Sam away, Castiel agreed with them, later discussing with Uriel his disdain for humanity and their true orders. Unfortunately, the Winchesters failed and Samhain rose, breaking another seal. After Sam exorcised Samhain with his powers and stopped him, Castiel met with Dean in a park and revealed that the angels true orders were always to follow *Dean's* orders, not to smite the town and that this was a test of Dean's battlefield leadership. Castiel reveals that he always hoped that Dean would chose to save the town whether or not they failed and that he secretly harbors doubts about Heaven and its plans.

> You misunderstand me, Dean. I'm not what you think. I was praying for you to save the town [...] These people ... they're all my Father's creations. They're works of art. [..] I'm not ... a hammer, as you say. I have questions, I have doubts. I don't know what is right or what is wrong anymore, whether you passed or failed here. But in the coming months, you will have more decisions to make. I don't envy the weight on your shoulders, Dean. I truly don't.
>
> Castiel's hidden compassion, It's the Great Pumpkin, Sam Winchester

 File:Castiel and uriel.png
When the angels learned that a woman named Anna Milton could listen in on angel's conversations they grew worried. If the demons were able to get to her before them, the demons would know everything that the angels were planning. But Castiel knew the truth: Anna had once been his angel superior Anael who disobeyed. She cut out her Grace and fell to Earth, where she was reborn as a human. Castiel and Uriel knew though that the only way to ensure the safety of their plans were to kill Anna. While Castiel was hesitant about this, Uriel enforced the idea that it was absolutely necessary.

Castiel and Uriel found Anna along with the Winchesters. The angels ordered Sam and Dean to hand over Anna, but they refused. The angels attacked them and almost retrieved Anna, but were sent away by a ritual Anna performed. They later were able to find Anna with the Winchesters again, but soon discovered that they had been led into a trap when Alastair arrived with a group of demons. The angels and demons fought over who would take Anna with Castiel fighting Alastair. Castiel proved no match for the demon, with his powers being useless, but Dean saved him despite being on opposite sides of the Anna situation. In the end, Anna retrieved her Grace and became an angel again and Alastair's body was destroyed, defeating him. Grateful for Dean saving him, Castiel held Uriel back from attacking Dean in revenge and they left to chase after Anna.

 File:Alastair-Castiel-alastair-26256003-1366-2000.jpg
When Alastair tried to break another seal by killing two Reapers on the night of the Solstice, Castiel managed to capture him having pretended to be Bobby to send the Winchesters after the seal. The angels held Alastair captive and when seven angels had mysteriously been killed, Castiel assumed that demons were behind the attacks. At this time, Castiel is put under closer watch by the angels, who believe him to be developing human emotions. He and Uriel recruited Dean to interrogate the demon. Castiel had grew self-conscious when Dean brought up Pamela's death and him burning out her eyes. Dean later spoke with him and asked him about his taking orders from Uriel as Castiel reveals he was demoted for getting too close to Dean.

During the interrogation, Anna returned and spoke with Castiel. She told him that she knew how he was feeling and that he was beginning to develop human emotions. Castiel refused to believe this and yelled at her, causing her to leave. Shortly after, the Devil's Trap Castiel had made to hold Alastair somehow malfunctioned and Alastair nearly killed Dean. Castiel fought the demon but was almost defeated when Sam came to his rescue, using his psychic powers to kill Alastair to Castiel's shock after torturing out of him that the demons weren't responsible for the angel deaths. While visiting Dean at the hospital, Sam criticized Castiel for being so cold-hearted as to risking Dean's life. This sunk into Castiel's head and he went to Anna for help, telling her he needed to know what to do; she told him it was time for him to decide on his own for once. Castiel investigated the broken Devil's Trap further and learned that it was Uriel who was behind the malfunctioning Devil's Trap and the angel killings.

Uriel reminded Castiel of the times when Lucifer was one of the greatest angels and also spoke about how God isn't doing anything and they must follow someone who would. Castiel refused and the two angels fought. Castiel was soon overpowered by Uriel and was beaten down but was saved when Anna appeared and killed Uriel with his own Angel Blade. Castiel then went to Dean and confirmed that Dean was responsible for breaking the first seal by giving in to Alastair's torture. Dean begged Castiel to find someone else because he wasn't fit to stop the Apocalypse.

Castiel later appeared when Dean interrogated Chuck Shurley, who was writing a book series based on the Winchester brothers, explaining that Chuck was a Prophet of the Lord. When Dean prayed for guidance, Castiel appeared and Dean asked him for help in saving Sam from Lilith, Castiel was initially hesitant to help, as Dean was angry and promised not to help him in the future. Before Dean could leave, Castiel dropped him a hint by telling him that Prophets are protected by Archangels, and that if a Prophet is in the same room with a demon, then the archangel will immediately descend to smite the demon. This caused Dean to get the idea to retrieve Chuck and put him in the room with Lilith, Dean thanked Castiel who wished him luck. Dean got Chuck in the room with Lilith which caused her to retreat while saving Sam.

Castiel then came to Dean while he was dreaming and told him to meet him at a certain location, saying that he had something to tell them. But when Dean and Sam arrived, they found him unconscious in a wrecked building with dead demons. When he awoke, the brothers found that Castiel had abandoned his vessel, Jimmy Novak, who describes being possessed by Castiel like "being chained to a comet." When Dean, Sam, Jimmy and Jimmy's daughter, Claire, were being held hostage by demons, Jimmy was shot and Castiel returned to possess Claire and helped save them all. Castiel was disgusted to see Sam consuming demon blood to exorcise the demon possessing Amelia Novak.

Castiel then told Jimmy that he kept his promise to protect his family and tried to comfort a dying Jimmy by stating he will take Claire as a host, Jimmy pleaded with Castiel to leave his daughter and take him back as a host and Castiel accepted. When Dean asked Castiel what he had been trying to tell him, Castiel coldly brushes him off and says his allegiance now is only to Heaven.

Later in *When the Levee Breaks* Castiel was summoned by Dean, who was screaming for three hours for help. When Castiel arrived, Dean asked him what happened in Heaven, but Castiel wouldn't say. Then Castiel recruited Dean in the service of God and his Angels. Castiel told him to wait till the Angels summons him. A few hours later he freed Sam from Bobby's panic room in which he was held captive, because of his addiction. Later Anna confronted Castiel about why he released Sam. Anna said that Sam was even worse than they had expected. Castiel told her that he has his orders to follow and said Anna shouldn't have come. The next moment two Angels stood beside her, and took her captive.

 File:Castiel starts his rebellion.png
Later Zachariah brought Dean to a chamber, so he would be safe for the release of Lucifer. Zachariah told him that the final seal would be broken that night. Although he had a fight with Sam, Dean tried to contact him on his cellphone, leaving a message on his voicemail. Later, Dean wanted to talk with Sam and summoned Castiel by breaking a Stone Angel on one of the tables. Dean asked to visited Sam, but Castiel said he could go everywhere except to Sam. Dean asked what they were going to do with Sam. Castiel said that Sam is going to do it to himself, but he didn't want to say more. He said it was his destiny. Dean said that destiny was just a bunch of lies, to keep him in line. Dean tried to persuade Castiel to help him, but Castiel said that they would be all be hunted and be killed. In response, Dean said to him that this is worth dying for. But to Dean's disappointment, Castiel refused and Dean ordered him away. Castiel tried to get Dean to listen, but left when he refused.

Shortly after, Castiel confronted Dean and drew an angel banishing sigil on the wall with his own blood after putting his hand over Dean's mouth to stop him from shouting until he realized Castiel was helping him. Then Zachariah appeared and demanded to know what he was doing. Finishing the sigil, Castiel pressed his bloody hand on the sigil, banishing Zachariah. He then told Dean Zachariah would be back and said that Lilith is the final seal and that Sam is going to break it. He said he knew someone that knew where Sam was and teleported Dean with him.

 File:Castiel and Chuck faces the Archangel.png
Castiel teleported Dean and himself to Chuck, the prophet of the Lord. Chuck was confused and said that this is not supposed to be, for this was not in the story. Castiel said that they would make it up. When they found out that Sam was at Saint Mary's, Chuck's computer goes off and bright light fills the room. Castiel said it is the Archangel and teleported Dean to Saint Mary's, so that he could hold the Angel off. At Chuck's house, Castiel looks up at the bright light. Seeing the angel's expression, Chuck puts his hand on Cass' shoulder, but when Castiel gives him a look, he removes it.

 File:Castiel confronts Zachariah.png
After witnessing the release of Lucifer from Hell, Dean and Sam went to Chuck's house to find Castiel. There they were told by Chuck that the Archangel smoked Castiel – literally – and they even find one of his teeth tangled in Chuck's hair. Later, when the Winchesters are trying to track down Michael's sword in their father's old storage unit, Zachariah and his angels arrived to inform Dean that he *is* Michael's sword—in other words, Michael's vessel. When Dean refused to give his consent for Michael to possess his body, Zachariah started inflicting various kinds of physical pain on him and Sam (breaking Sam's legs and removing his lungs, and giving Dean stage-four stomach cancer), all the while refusing to kill them. Castiel then miraculously appeared and dispatched Zachariah's men, a stunned Zachariah questioned his return. Castiel hinted at God's involvement at his return and the rescue of the Winchesters. He then forced his scared brother to heal the Winchesters and leave, to which Zachariah reluctantly complied. He then used his powers to carve Enochian sigils on their ribs, keeping them hidden from all demons and angels, including Lucifer and himself. Castiel confirmed his death to Sam but when Dean asks him how is he alive, Castiel disappears before giving him an answer.

After rebelling against the angels, Castiel goes on a mission to find God in hopes he will be the one to stop Lucifer. He uses Dean's amulet for this, which is said to glow hot in God's presence. It's revealed Castiel's powers are also diminished, cut off from Heaven, and he is at first mad at Sam and Dean for failing to stop Lucifer's rise when he literally "lost everything". However, despite his, he continued to be invaluable ally to the brothers saving them on numerous occasions.

> I killed two angels this week. My brothers. I'm hunted. I rebelled. And I did it, all if it, for you. And you failed. You and your brother destroyed the world. And I lost everything ... for nothing. So keep your opinions to yourself.
>
> Castiel to Dean for doubting his plan, Good God, Y'all

As of *Free To Be You and Me*, he is continuing at looking for a way to find God, Castiel approached Dean for help in capturing and interrogating Raphael on God's location. After Castiel retrieved Holy Oil for the trap, Dean took him to a strip club after learning that Castiel was a virgin so he wouldn't die as one. Castiel was clearly nervous in the strip club and ended up angering the stripper by telling her that her father left because he hated his job, not her.

Castiel and Dean later succeeded in trapping Raphael, who told them God was dead but Castiel rejected this by bringing up his resurrection, to which Raphael stated Lucifer could have did it. Though Castiel denied this and decided to leave, as Raphael demanded his release and threatened to find them, but Castiel left him where he was, telling him that "Maybe one day, but today you're my little bitch" a comment that Dean agrees with.

 File:RdsideDCas.jpg
In *The End*, Castiel contacts from a cellphone and tries to retrieve him but a tired Dean sets a time for him to get him. Zachariah discovered Dean's location and sent him to an alternate post-Apocalyptic future in which Lucifer had ravaged the world with the Croatoan Virus. Castiel is the only angel still fighting for the sake of humanity. He had lost his powers but joined Future Dean's resistance movement against Lucifer, he also could still tell Dean was from the past when meeting him despite acting in self-indulgence with women of the army. He presumably died in the final confrontation against Lucifer. After Dean is returned to the main world, Zachariah tries to properly secure Dean as Michael's vessel but Castiel was able to rescue Dean from his brother by teleporting him away. Castiel remarks that he and Dean set a point and that he retrieved him exactly. Dean told him to never change before he called Sam.

 File:CasCallsInstead.jpg
In *The Song Remains the Same*, when Anna returns and tries to make contact with Sam, Castiel meets her instead. He had convinced the Winchesters to stay behind because he did not trust her. After Anna revealed her plans, Castiel refused to let her kill Sam by declaring him as his friend and threatened to kill her if she still tried, regardless of their history. Anna remarked on his change in loyalty, as he commented that it may have came to late but Anna still had a plan and left.

Castiel did not sense Anna's presence and realized she went back in time to 1978 to kill John and Mary Winchester so that Sam and Dean wouldn't be born to break the first and final seals. Castiel tried to go after her alone but was encouraged by the Winchesters to take them back in time to stop her, which he reluctantly agrees too.

The trio traveled to the past but the journey caused Castiel pain as the brothers let him rest in a motel as they went after Anna. At the end, Anna is killed by Michael who sends the brothers back to their time while Castiel regained enough power to return to the future. Once he touches down, he is again helped by Sam and Dean who lay him down on the bed. While Castiel lays down, Dean counts him, himself and Sam as Team Free Will.

 File:SadCupid2.jpg
During *My Bloody Valentine*, Castiel is called by Dean and Sam for assistance when they are working on leads them to hearts with Enochian sigils carved on them. While they initially believe that a rogue cupid is killing people, the true culprit, Famine, affects Castiel through his vessel, Jimmy Novak, who apparently has a craving for hamburgers. Castiel stuffs himself throughout the episode, much to Dean's disgust, and asks Dean why he hasn't been put under Famine's curse. When Dean explains that he doesn't deny himself anything, Castiel asks, "So you're just well-adjusted?" The original plan to kill Famine was to send Castiel in; however, this ends badly when Castiel is distracted by a slab of raw ground beef and his craving takes affect. Later on, Castiel snaps out of it after Famine is incapacitated by Sam. However, Castiel is concerned for Sam's addiction and the latter is locked up to go through to detox. Castiel attempts to comfort a sullen Dean, though it doesn't appear to work.

 File:StatiCas.jpg
After Sam and Dean were kidnapped by the Trickster, Castiel searched for them and came to their rescue but was stopped by the trickster who teleported him away. A battered Castiel later made his way back long enough to warn the Winchesters that the Trickster was too powerful to be a trickster though before he could elaborate, he was flung aside. The Trickster himself then appeared, bound Castiel's mouth as he greeted Castiel amicably and effortlessly banished him. The Trickster's familiarity with him along with Castiel's information and various clues caused Sam and Dean to realize the Trickster was actually an angel. Their theory is confirmed as the trickster is revealed to be the Archangel Gabriel after they trapped him in a Holy fire circle, Dean forced him to bring Castiel back from wherever he'd put him. Once he returned, Castiel assured Dean that he was okay before he greeted his brother coldly, revealing he figured out the latter's identity too. Gabriel returned this sentiment by taunting Castiel about his pointless search for their father. Castiel watched the end of Sam and Dean's confrontation with Gabriel, before Dean releases Gabriel from the ring of fire.

 File:Photo.jpg
When Sam, Dean, Ellen Harvelle and Jo Harvelle went after Lucifer, Castiel joined them, drinking shots with Ellen before they took off and taking a picture with the group. In Carthage, Castiel separated from the group to follow a Reaper and was captured and held in Holy Fire by Lucifer who tried to convince the angel to join him. Castiel refused and was held captive by Meg who taunted him. However, Castiel managed to loosen a pipe and use it to knock Meg into the circle where he tried to smite her only to find he'd lost that power. Castiel used Meg's body as a bridge to escape and teleported Sam and Dean, the only other survivors of the failed mission, away from Lucifer.

 File:5x16-Dark-Side-Of-The-Moon-dean-and-castiel-27613425-1248-704.jpg
When the brothers were ambushed and killed by two hunters furious with them for causing the Apocalypse, Castiel warned the brothers that Zachariah was looking for them in Heaven and they should attempt to contact an angel named Joshua, who was rumored to speak to God. After talking with Joshua, it was confirmed that God was the one who resurrected Castiel not Lucifer as Raphael suggested.

When the brothers returned from death, Sam revealed that God wanted nothing to do with them, causing Castiel to abandon his belief in God and return Dean's amulet, stating that it was worthless.

As seen in *99 Problems*, Castiel fell into a depression and drank heavily, but sobered up in time to help defeat the Whore of Babylon.

In *Point of No Return*, Castiel helped Sam bring Dean to Bobby's house where was angry with Dean's decision to say yes to Michael before he sensed something. He went to another area and fought three angels before bringing back the Winchester's half-brother Adam who has been resurrect. Castiel carved Enochian sigil on Adam's ribs to prevent the angels from finding him, causing him to wake up. When Adam mentioned, he was brought as a substitute vessel for Michael instead of Dean, Castiel confirmed its possible since Adam is of the Winchester bloodline. Later on, he and Sam lock Dean away in the panic room to prevent his escape. At one point, Dean banished Castiel but the latter returned after sensing a man praying to the angels allowing Cass to locate Dean and he angrily shouted he had sacrificed everything to follow Dean as he believed in him. Castiel proceeded to beat Dean up out of pure rage before calming himself and taking him to Bobby. When Sam and Dean go to rescue their brother Adam Milligan who had been taken by Zachariah, Castiel carved an angel banishing sigil into his chest and uses it to banish four angels and himself after showing his lack of faith in Dean by saying at least he won't have to see Dean fail. However, Dean ultimately doesn't go through with saying yes to Michael and kills Zachariah instead though Michael takes Adam.

In *Two Minutes to Midnight*, Castiel returned powerless, apparently from the banishing sigil. He apologizes to Dean for doubting him and comes to their aid when confronting Pestilence, stating to the horseman that he used the bus to get there.

In his weakened state, Pestilence easily brings Castiel down, but he possesses just a "speck" of his angelic self left, just enough to resist Pestilence's power long enough to cut off his ring and defeat him. Castiel later joins Bobby and Sam in an assault on Niveus to stop the Croatoan Virus, bemoaning his lack of power. Despite this, Castiel does a good job, stopping a truck loaded with the virus from leaving and killing a zombie with a shotgun (which he remarks is actually useful) saving Sam's life.

In *Swan Song,* now almost completely human, Castiel accompanies Bobby, Dean and Sam to Detroit where Sam will say Yes to Lucifer as part of their plan. Castiel awkwardly says goodbye to Sam and tries to reassure him that they will be okay, but is bad at it. When Sam fails to overpower Lucifer, Castiel loses hope and suggests they get drunk and wait for the end to come. Dean refuses to give up and manages to get Castiel and Bobby to help him. In the final confrontation, when Michael (in the vessel of Adam) was about to fight Lucifer (in the vessel of Sam) Dean intervened saying he wished to speak with Sam. This prompted Michael to try and remove Dean, however, before he could respond Castiel teleported into the field with Bobby and insulted his brother as he threw a Molotov of holy fire at Michael, sending him back to Heaven for a brief time.

 File:Castiel brought back as an Archangel.png
Lucifer turned to Castiel, furious by the fact that Castiel harmed his brother. Castiel for the first time showed fear when he realized that he had enraged Lucifer, who snapped his fingers and caused Castiel to explode. Shortly after the battle between Dean and Lucifer where Sam was able to retake control and throw both himself and Michael into the Pit, Castiel was resurrected by God and appeared to Dean telling him he was brought back new and improved with his angelic powers restored and upgraded, allowing him to restore Dean's broken bones and bring Bobby back to life. Castiel, now a Seraph, said that he needed to return to Heaven to restore order to the anarchy that will follow Michael's departure.

> With Michael in the cage, I'm sure it's total anarchy up there. [...] I don't know what God wants. I don't know if he'll even return. It just ... seems like the right thing to do.

> Castiel deciding to restore order in Heaven, Swan Song

#### Return to Heaven

> No one leads us anymore. We're all free to make our own choices and choose our own fates. [...] God wants you to have freedom.

> Castiel to angels during his return, The Man Who Would Be King

After the Apocalypse was averted, Castiel managed to save Sam and pull him out of Lucifer's Cage with his enhanced powers, though didn't know at the time he hadn't brought him back with his soul. Castiel visited his favorite part of Heaven – a Tuesday afternoon of a 40-year old autistic man who drowned in a bathtub in 1953 – where other angels awaited him. Castiel preached freedom to them instead of having a leader, but they don't know how. Castiel struggled in Heaven his first few weeks back as he tried to get the angels to embrace freedom, later likening it to "teaching poetry to fish." During this time, Castiel was confronted by Raphael. Castel and Raphael clash over their different ideologies for Heaven – Castiel with his emphasis on freedom and peace while Raphael wants to free Michael and Lucifer from the cage to start the Apocalypse again. Raphael tries to get Castiel to bow to him, but Castiel refuses.

Due to his defiance, Castiel is no match for him and threatened to submit or suffer. Castiel tries to get help from Dean, but seeing Dean retired makes Castiel rethink this. Crowley suddenly approaches Castiel, proposing him a deal to have him grow strong enough to defeat Raphael by collecting monster souls if he lets Crowley have access to Purgatory. Crowley also suggests he lead Heaven since he is the only angel to be resurrected by God, though this would start a civil war. Castiel refuses all propositions, but begins to consider it when Crowley twists it as either his option or the apocalypse all over again. Castiel reluctantly agrees to the deal. Crowley resurrects Samuel Campbell (the Winchester's grandfather) to help them find Purgatory while giving Castiel fifty-thousand souls from Hell to power him up against Raphael for the time being.

Castiel, powered up with souls, challenges Raphael and divides Heaven between him and the archangel. Castiel also cuts contact off from Sam, who repeatedly prayed to him many times for explanations on getting out of the cage.

> There will be no Apocalypse. And let it be known – you're either with Raphael or with me.

> Castiel starts the civil war, The Man Who Would Be King

### Season 6

> Raphael and his followers, they want him to rule Heaven. I -- and many others -- the last thing we want is to let him take over. It would be catastrophic. [..] Whoever has the weapon wins the war.

> Castiel's ongoing battle with Raphael, The Third Man

Castiel struggles with the civil war in Heaven against Raphael. When Sam and Dean found out plagues were unleashed upon the Earth, they called Castiel for help. Castiel didn't answer for Sam but showed up for Dean and told them the Angelic Weapons were stolen from Heaven. Castiel withholds his involvement with Sam's return by claiming to not know what or whom brought Sam out of his cage.

 File:Raphael vs Castiel.jpg
During their investigation, they find out that an Angel has been moonlighting as a crossroads demon. To locate the angel's name, Castiel performed a ritual to find the angel that bought the soul. When Castiel learned it was his old friend, Balthazar, an angel follower of Raphael showed up and attacked Castiel. Castiel managed to defend himself and let the angel get away, but the angel knew that Balthazar was selling pieces of the Staff of Moses. So Castiel, Dean and Sam try to find Balthazar first, and when they do, Balthazar admitted that he stole the weapons from Heaven and that he want to live in freedom. When Balthazar disappears, Castiel is confronted by angels who want to kill him. Castiel asked them to join him, but they refused and Castiel killed them. Afterwards, Raphael showed up and told him that they were his followers and attacked Castiel before defeating him. Raphael voiced his doubt of God bringing him back again but just as he was about to kill Castiel, Balthazar showed up and used the weapons from Heaven to destroy Raphael's vessel. Eventually, Sam and Dean showed up and were able to trap Balthazar in a circle of holy oil, but Castiel lets Balthazar go after they force him to let go of his hold on the soul with Castiel's reason being that he owed Balthazar his life.

 File:SPN 0441.jpg
Dean becomes more and more disturbed by Sam's behavior, and prays for Castiel's help. Castiel doesn't respond until Dean calls him about a possible loose nuke, much to Dean's aggravation. Castiel apologizes, but reassures Dean on his theory that Sam is not Lucifer, explaining that all angels would feel his presence if Lucifer was free. Castiel also states he doesn't know what's wrong with Sam, but he promises to make inquiries. Dean calls on Castiel once he has Sam unconscious, and asks for him to diagnose Sam. Castiel informs both brothers that physically, Sam is perfectly healthy, but his soul is missing. He guesses that Sam's soul is still in the cage with Michael and Lucifer. When Sam goes with Samuel as his only lead, Castiel follows Sam and Dean to the Campbell Compound. He meets the Winchesters' grandfather Samuel Campbell who is amazed to see him before he checks if Samuel has a soul or not, which he does. However, before he can do any more to help, he states he needs to return to Heaven, but reassures Sam and Dean that their problems "always come first", and will keep in touch.

Castiel is later called on for assistance by Sam, who tricks him into leaving Heaven by saying he and Dean have found the Ark of the Covenant. Sam tries to coerce Castiel into joining them along with the demon Meg and her minions to confront Crowley, but fails as Castiel knows Sam can't harm him. However, recognizing that Sam really does need help, Castiel decides to help anyway. Castiel tries to track down Crowley by means of a ritual, which leads them nowhere. When the group is caught by Samuel as they search through his quarters, Dean asks for the angel to leave back to their motel.

 File:Castiel watches the Pizza Man.jpg
Sometime later, while Sam and Dean are looking through records trying to find Crowley, Castiel is confounded by watching porn, which he states just happened to be on the TV. He creates an awkward moment with the Winchesters, even creeping Samuel out upon arriving at their motel. He leaves with the group after Samuel gives them the location of Crowley's prison. Before leaving for the prison, Castiel suggests to Dean that he doesn't think restoring Sam's soul is wise. He supports his statement with the fact that his soul has been locked in the cage with Michael and Lucifer for more than a year, and they have been doing nothing other than taking their frustrations out on Sam. He theorizes that if they try to force the damaged, tortured soul back into Sam, and if they fail to deal with the problems, then Sam will suffer horrifically.

 File:Supernatural-–-6x10.jpg
The group then leaves for the prison, and Castiel finds a back entrance inside. Shortly after, hell-hounds come after the party. Meg distracts Castiel by kissing him, and steals his angelic blade. Castiel, surprisingly, responds to this by kissing her back, stating he learned that from the porn he was watching earlier. The boys then run off while Meg holds off the hell-hounds with the angel blade. Later, Castiel is banished by a blood sigil cast by a treacherous Samuel, while the Winchesters are taken captive.

While Crowley has the boys pinned to the wall, Castiel reappears, carrying a large bag. After Crowley taunts him about his losing war against Raphael, Castiel reveals that the bag contains his salvaged bones. The angel asks the King of Hell one last time if he can restore Sam's soul or not. Crowley says he cannot, and Castiel proceeds to burn his bones, seemingly turning him to ash. However, it's later revealed Castiel deceived the Winchesters considering his deal with Crowley and the bones were the wrong ones.

A short moment later, outside the prison, Castiel later admits that he is on the losing side of the civil war in Heaven, and expresses disappointment as he wishes much of the time that circumstances were different as he prefers being on Earth with Sam and Dean. Dean then reassures the angel that they will help in whatever way they can, and that the brothers are his friends. Castiel then turns to Sam, and reassures him that they will find another way to get his soul back. Sam then asks him to dispose of the monsters that still remain inside the prison, to which Castiel presumably leaves to do so.

> It's not going well for me upstairs [...] I wish circumstance were different. Much of the time I'd rather be here.

 File:SPN 0769.jpg
After Sam gets his soul back, Castiel comes to check up on him, and tells Dean that he doesn't think Sam is ever going to wake up while criticizing him for not heeding his warning about the soul. A few hours later, Sam wakes up and reunites with his brother while happy to hear Cass is alive since he recalled Lucifer killing him. Later on, Sam, now with his soul again, calls Cass and Castiel comes. He tells Sam that he is glad to see him well, despite everything, nearly hugging him. Sam tells Castiel he would hug Castiel, but it would be awkward. Sam goes on to talk about how its been a crazy year and how he just talked to Bobby about it. Castiel tells Sam he's surprised Sam even survived. Castiel asks Sam how it feels as Sam looks confused. Castiel explains, "to have your soul back". Sam tricks an unaware Castiel into telling him the truth while learning about his soulless year.

In *My Heart Will Go On*, Castiel saves Sam and Dean from Fate, when she tries to get her revenge for stopping the apocalypse. He tells the brothers if they want to live, they need to kill Fate. So Sam and Dean draw Fate out and just as they face their death, time freezes. Castiel is confronted by the Fate Atropos who reveals the real reason why Balthazar saved the Titanic was because Castiel ordered Balthazar to do it for the souls. She threatens to kill Sam and Dean unless Castiel fixes history. Choosing his friends safety over the war, Castiel orders the creeping Balthazar to refrain from killing Atropos and to right history.

> You're the ones that taught me that you can make your own destiny. You don't have to be ruled by fate. You can choose freedom. I still believe that's something worth fighting for. I just wanted you to understand that.

> Castiel to Sam and Dean, My Heart Will Go On

Afterwards, Castiel tells Sam and Dean that he made sure they kept their memories of the alternate timeline as he wanted them to know of the choice he made. He lies that of Balthazar's motives on the matter and leaves the area.

 File:Castiel wounded.png
In *Frontierland*, Cass returns to send Sam and Dean back to the Wild West so the brothers could acquire ashes of the phoenix, the one thing that could kill the mother of all. He tells Sam and Dean they have only 24 hours, after that he will no longer be able to find them. During the time the boys are in the Wild West, Castiel's lieutenant, Rachel, confronts him about his side dealings Castiel is doing to win the war. This leads to a duel between the two, and Castiel emerges the winner and wounded. He soon heads to Bobby's, draws a symbol in his blood and passes out. As time grows short, Castiel re-awakens, but is very weak and low on power. In order to "power up" he tells Bobby he needs to touch Bobby's soul. Once powered up, Castiel brings the boys back.

 File:Cascrowley.jpg
Now with the ashes, the hunt for Eve is on. Castiel comes to Sam and Dean asking for Eve's location, but they too are unsuccessful. Sam suggests that they find a good monster who would be willing to give them Eve's location. Castiel finds and brings Lenore, who gives them Eve's location, in exchange for her death. Sam is hesitant, but Castiel brings Lenore her end. This action makes Sam and Dean concerned about Castiel and his circumstances. Once they arrive in Oregon, Castiel discovers he can't use his powers, and is now powerless, thanks to Eve. Castiel is able to torture Eve's location out of a Jefferson Starship, but is captured by her monsters. After Dean kills Eve, Castiel's powers return and he slays the Jefferson Starships with a blast of white light. Castiel is later revealed to be working with Crowley after the Winchesters' encounter with Eve.

 File:Sfonews0144.jpg
The truth finally comes out in *The Man Who Would Be King*, Castiel recounts history from his point of view and how the Winchesters inspired him. Castiel is shown clearly conflicted over his partnership with Crowley, but agrees to keep the Winchesters from finding him. Castiel also begins to notice that Sam, Dean, and Bobby are getting suspicious of Castiel and believe he is working with Crowley, strengthening his guilt. After catching a lead of a demon called Ellsworth and Crowley's other higher up demons, Castiel goes and smites them before Sam and Dean can get information. He justifies this as protecting them from Crowley, but also wonders if it's to protect himself. He reflects on his return to Heaven after the Apocalypse, the conflict between him and Raphael that was sprung up, and his fateful deal with Crowley.

Castiel tries to minimize contact with Sam and Dean, knowing they were on to him and he could give them no honest answers. However, when Crowley sends his best demons to fight them, Castiel shows up to save them. Although Castiel managed to keep the secret for a while, he slipped up with information he got from spying on them. Castiel is furious with Crowley's attempt to kill Bobby, Sam and Dean, warning him that if anything happened to them he would call off their deal and kill him himself.

 File:Castiel-HolyFire-TMWWBK.jpg
Later the boys trapped him in a ring of holy fire and confront him about his betrayal. He pleas to them to understand his plight, even revealing to them that he was really the one who rescued Sam from Lucifer's Cage not Crowley. However, he is accused by Sam of bringing him back soulless intentionally which he quickly denies. When demons come, Castiel tells them to run and they leave him in the ring of holy fire. Crowley comes in and saves him. Castiel leaves, and comes to Dean, trying to explain the situation. Castiel tells Dean that he did this for Dean but Dean does not want it this way. Castiel responds that Dean can't stop him and says he's sorry and disappears. Castiel tells his father God all of this when he's by himself, praying for a sign if he's making the right choice, but gets no answer.

> So that's everything. I believe it's what you would call ... a tragedy from a human perspective. [...] That's why I'm asking you, Father. One last time. Am I doing the right thing? Am I on the right path? You have to tell me. You have to give me ... a sign. Give me a sign. Because if you don't ... I'm gonna ju- I'm gonna do whatever I ... whatever I must.

> Castiel praying for answers, The Man Who Would Be King

 File:BalthazarandCas.jpg
In *Let It Bleed*, Castiel has taken one of the Campbell diaries, and is investigating an incident in which H.P. Lovecraft opened a portal to another world. Sam prays for him, telling Cass that Lisa and Ben have been kidnapped by Crowley, and asks for help. Castiel listens unseen, and does not answer, but goes to confront Crowley. He insists that the demon not harm Lisa and Ben, but Crowley refuses to make such a promise. Balthazar later calls him. He asks Cass if he is planning on opening the door to Purgatory; Cass lies that he is not, but Balthazar is not fooled. Castiel asks if he is with him, or not. Balthazar says he is, and Castiel goes to Dean, arriving just in time to save him from a demon. He apologizes for Lisa and Ben, revealing that he did not know Crowley's plan. Dean is skeptical, and angry. Castiel asks him again to support his decision to tap the souls in Purgatory. He pleads with him that he has always done what the brothers needed him to, asking little in return. Cass asks them to trust in him, and promises to bring him his family afterward. Dean is unwilling, and Castiel leaves. After Dean and Sam rescue Lisa, Castiel comes to the hospital where the gravely injured Lisa is not expected to survive. He apologizes again, but Dean is not forgiving. Castiel says that he did not come for Dean, then places a hand on Lisa's forehead, healing her. Both Dean and Cass acknowledge that this does not change their situation, but Dean asks for an additional favor. Castiel removes all Lisa and Ben's memories of Dean. Later Castiel finds and takes Dr. Visyak, the creature he needs to open Purgatory.

> I thought that you said we were like family. Well, I think that too. Shouldn't trust run both ways? [...] Dean, I do everything that you ask. I always come when you call and I am your friend. Still, despite your lack of faith in me and now your threats, I just saved you yet again. Has anyone but your closest kin ever done more for you?
>
> Castiel's appeal to Dean, Let It Bleed

In *The Man Who Knew Too Much*, Castiel and Crowley torture Dr. Visyak until they obtain what they need to open Purgatory. She escapes and contacts Bobby and the Winchesters, telling her story before dying in an alley from her injuries. Castiel comes to the three hunters, who are outraged. Dean tries to argue with him again, but Cass cuts him off, saying he no longer cares about Dean's opinion. He then touches Sam's head, breaking the mental wall, and promising to repair him as long as Dean stops the opposition.

 File:Castiel becomes a god.png   Castiel meets with Crowley, who has assembled the necessary ingredients. The angel wants to renegotiate their deal. He will not give Crowley the souls, so Crowley can either flee or die. The demon leaves Castiel with the blood for the ritual. Later, Castiel confronts Balthazar. He says that Dean is coming, and someone among them is a traitor. Balthazar asks him who it is, and Castiel lies that he does not know, and wants Balthazar to investigate. While the other angel is distracted, Castiel stabs and kills him. Just before the ritual is meant to begin, a cloud of demons descends around the building, and Crowley appears. Castiel tries to kill him, but cannot. He has a new partner in Raphael. Castiel is surprised at the partnership with their differing goals, but both seem to think they have taken the best course available. They demand the blood; Castiel throws them a jar and leaves. Crowley conducts the ritual, and though Bobby and Dean try to interrupt, completes it.
Nothing happens and Castiel reappears. Crowley realizes that he switched the blood, and conducted his own ritual. Castiel displays his power briefly in a flash of energy. Crowley, realizing the game is up for the time being, wisely disappears, and Raphael asks for mercy.

 File:Raphael implosion.gif
But Castiel is not in a forgiving mood. He snaps his fingers, obliterating Raphael to pieces in mere seconds. He turns to Dean and Bobby. He was right, he says, and he did save them. Dean nervously agrees, then suggests that Castiel should return the souls, and disarm himself. Castiel says he has Raphael's followers to deal with. Dean is worried, and reminds Castiel that he is family, and he doesn't want to lose him. Castiel says that he has no family anymore; he will not give up the souls.

 File:Castiel god.png
Using that moment, Sam stabs him from behind with an angel sword, but nothing happens. Castiel greets him, then says the sword will not work because he is not an angel anymore. He says that he is their God, and that they must venerate him, or be destroyed. As he says those words, Dean, Sam and Bobby look on in horror, realizing with shock that their former ally and friend has become a power-hungry angel who believes that he is God.

> You doubted me. Fought against me. But I was right all along. [...] You're not my family, Dean. I have no family. [...] I'm your new God. A better one. So you will bow down unto me, your Lord. Or I shall destroy you.

### Season 7

> If you followed Raphael, if you stood against me, punishment is certain. There is no where for you to hide. The rest of you ... our father left a long time ago, and that was hard. I thought the answer was free will. But I understand now. You need a firm hand. You need a father. And I am your father now. [...] It is a new day, on Earth and in Heaven. Rejoice.

> Castiel as God, Meet the New Boss

 File:SPN 0044.jpg
Castiel waits for Sam, Dean, and Bobby to show their respects. Bobby goes to his knees, and motions for Sam and Dean to do the same. Dean and Sam begin to kneel, but Castiel stops him, and orders Bobby to stand, saying that there is no point if they do not mean what they do. Castiel observes, without turning to look, that Sam is not doing well. Dean reminds Cass that the former angel promised to fix Sam when it was over. Castiel cuts him off; his promise was contingent on Dean not opposing him further, and oppose him Dean did. Castiel tells them he has no need to kill them, though he no longer has any regard for them, and will let them live if they do not plot against him.

 File:SPN 0158.jpg
Castiel sets out to right the wrongs he sees. He destroys Raphael's followers in Heaven, vaporizing thousands of angels, and tells the survivors that he no longer thinks free will is what Heaven needs. Instead, he will give them a firm hand. He appears in a church, reveals his identity, and smites a hypocritical preacher. He leaves an image of himself in the stained glass as he departs, and accidentally burns a pew as welts appear on his hand.

He finds Crowley hiding in a RV, and tells him that he may retain his position as King of Hell, but that Castiel will choose which souls he receives. He claims that he would have destroyed Hell completely, but he needed it to threaten his enemies, and maintain Michael and Lucifer. It is unknown if he actually had the power to destroy Hell, or he was over his head with all the souls inside him. He leaves after looking at yet more open places on his skin. He gives money to a blind man on the street, and heals the man for his faith. The man is grateful, but surprised when his first sight is of Castiel's blistering face. At a nearby bathroom, he looks in the mirror and stares at the blisters covering his face and hands. His stomach begins to bulge and contort as the Leviathans demand to be let out, whispering to him as he looks down in horror, mumbling "No."

 File:SPN 0997.jpg
Sam, Dean, and Bobby summon Crowley, who reluctantly gives them a spell to bind Death. They work it, and an irritated Death appears, followed shortly by Castiel. Dean orders Death to kill 'god'. Death says he sees only a mutated angel, one whose vessel is disintegrating. Castiel, sounding uncertain, says he will heal himself when his works are complete. Death replies that Castiel swallowed Leviathans when he emptied Purgatory, not just souls, and that is the danger. Castiel is surprised to hear this, though tells him that he controls them but Death is not sure. Dean ends the argument and tells Death to kill Castiel, who frees Death from Dean's binding spell. Castiel leaves in a hurry.

 File:SPN 1120.jpg
At a political election office campaigning for a senator of whom Castiel disapproves, he is stopped by one of her aides. Castiel asks the man to see that he is a good god, that he means the best for his children. He awakes some time later in a pool of blood on the floor. He has slaughtered the entire office. At Bobby's place, Sam prays for Castiel to reconsider and give up the souls. A few minutes later Castiel appears, disheveled, bloody, and looking ill. He says he heard the prayer and needs their help.

 File:SPN 1455.jpg
He listens to Sam's call and agrees to put all the souls back in Purgatory. Before the opening of the door, he expresses regret at what he has done and wishes that he could have restored Sam back to normal, and promised to do so if he survived. After he lets out all the souls, Cass passes out but wakes up. He automatically begins to contort and struggle as the Leviathans had held on to his body are trying to take over.

> I feel regret, about you and what I did to Sam [..] If there was time, if I was strong enough, I'd--I'd fix him now. I just wanted to make amends before I died.

> Castiel to Dean, Meet the New Boss

 File:SPN702-01.jpg
Castiel is soon overpowered by the Leviathan who in turn take control of him, presumably taking him far away. They begin by throwing Dean and Bobby against a wall before saying that they're going to have fun now. Soon after flinging them, his vessel begins to ooze black blood, and Dean smugly points out that the vessel can't contain the power of the Leviathans. They leave saying they will be back for Dean. The Leviathans are able to guide Castiel's vessel to a water reserve and the vessel explodes in a whirlpool leaving the Leviathans to escape into the water. Later, his trenchcoat is found, Dean folds it up and takes it with him.

It was later revealed in *Slash Fiction* that the Leviathans learned of Sam and Dean's aliases from Castiel's mind before they escaped from inside him.

 File:717.jpg
After being killed by the Leviathans, Castiel was resurrected by God and awoke with no memory of what he was or his past. He was found by a religious woman named Daphne, who declared "God wanted her to find him". Castiel named himself **Emmanuel** and lived with Daphne, his wife as a healer. Dean hears word of his healings and is shocked to see Castiel alive, but refrains from telling him the truth of who he is and tells him to heal Sam, who had been driven insane by his hallucinations of Lucifer. Castiel figures out he has a past with Dean and Meg, but fully regains his memories after smiting demons guarding Sam's ward. Castiel is angry and ashamed of himself for all the death he had caused and nearly leaves out of guilt, but Dean convinces him he can still fix things.

> **Castiel**: "Do you have any idea the death toll in Heaven? On *Earth*? We didn't part friends, Dean. [...] I deserved to die. Now I can't possibly fix it ... so why did I even walk out of that river?"
> **Dean**: "Maybe *to* fix it.
>
> Castiel after regaining his memories, The Born-Again Identity

Motivated by Dean, Castiel apologizes to Sam for breaking down his wall and attempts to rebuilt it only to discover it was completely destroyed with Sam's collapsing mind. In one last effort to redeem himself, Castiel shifted the hallucinations of Lucifer from Sam's mind to his own in order to save him. Castiel then looked on in horror as he saw the hallucinations of Lucifer Sam seems better than ever and regains his sanity, though at the cost of Castiel's own. He is admitted to psychiatric ward. Meg becomes a nurse through partially out of a deal with Dean to look after him.

 File:I'mSorry.jpg
In *Reading Is Fundamental*, Castiel awakens from a coma when The Word of God is released from the clay containing it, but is still insane with an eccentric personality. Castiel explains what the Word is, but is unable to give Dean the answers he seeks and Dean is still angry with him for what he did to Sam. Castiel no longer fights anymore and tries to "avoid conflict". While talking to Dean, Castiel senses other angels and finds Hester and Inias, two angels from his former garrison. While Inias is happy to see him, Hester is furious due to the damage he caused. Before things can degenerate too far, Dean banishes all three angels. Castiel later meets up with the group on the road to Rufus's cabin and helps angel-proof it. In a conversation with Sam, Castiel reveals he's been more at peace ever since he took on Sam's memories of Hell and liked his being insane than being guilty and sane.

> It's funny. I was- I was done for too. The weight of all my mistakes, all those lives and souls lost ... I-I couldn't take it either. I was ... lost until I took on your pain. It's strange to think that helped, but ...
>
> Castiel's apparent peace with his insanity, Reading Is Fundamental

When Meg returns, he confirms her story that she killed other demons, but warns that she has drawn the attention of the angels. Hester and Inias arrive with two other angels, but in his mental state, Castiel is now a pacifist and refuses to fight, even to save his own life. Castiel is nearly killed by Hester, but Meg kills her and saves him. Afterwards, Inias offers Castiel the chance to return to Heaven, but he chooses not to as he no longer feels like he belongs there.

 File:723 Dean Castiel and Sam.jpg
Sam and Dean discover from the translation of The Word of God that they need the blood of a Fallen Angel for the weapon that can kill Leviathans and Castiel happily gives them his blood telling them "always happy to bleed for the Winchesters." Castiel then disappears, not sure where he's going next, something he finds amazing.

 File:Dean Cass in Purgatory.png
In *Survival of the Fittest*, Castiel has Meg bring him to the Winchesters after learning that the Leviathans have killed all of his garrison. Crowley arrives and is furious to see Castiel alive, but leaves him alone as he is insane and he doesn't want to pick a fight with a crazy person. He also leaves Meg alone when Castiel gets defensive of her, telling Sam and Dean that Castiel is vital to defeating the Leviathans. Castiel denies any knowledge of what he's talking about however. After finding out that the Leviathan leader Dick Roman has made multiple copies of himself, Dean turns to Castiel for the help Crowley said he could give them, but he refuses to do anything due to his new pacifism and fear of messing up again. Meg reveals that due to being the Leviathans original vessel, he possesses the ability to tell them apart and could identify the real Dick Roman.

> I can't help. You understand? I can't. I destroyed ... everything and I will destroy everything again. Can we please just leave it at that?
>
> Castiel refusing to help, Survival of the Fittest

After watching Bobby being put to rest, Castiel takes Dean to retrieve the Impala and explains his reasoning for refusing: he feels that he is bad luck and will cause more harm than good if he gets involved again. Dean finally forgives him for what he did to Sam and Castiel agrees to help. The next day, while Sam rescues Kevin Tran, Castiel and Dean make their way through SucroCorp looking for the real Dick.

> **Castiel**: "If we attack Dick and fail, then you and Sam die heroically, correct? [...] Or at best, *I* die trying to fix my own stupid mistake. Or I *don't* die. I'm brought back again. I see now. It's a punishment resurrection. It gets worse every time. [...] I'm not good luck, Dean.
> **Dean**: "Yeah, but you know what? Bottom of the ninth, and you're the only guy left on the bench. Sorry, but I'd rather have you, cursed or not. And anyway, nut up, alright? We're *all* cursed. I seem like good luck to you?"
> **Castiel**: "Well, I don't want to make you uncomfortable ... but I detect a note of forgiveness. [...] I'll go with you. And I'll try my best."
>
> Castiel deciding to fight with Dean, Survival of the Fittest

Soon enough, they confront Dick. Castiel tries to take Dick on, but is thrown into a wall and easily defeated. This allows Dean to stab Dick with the weapon, but it doesn't work. This causes him to lower his guard as Castiel restrains Dick from behind while Dean stabs him through the neck with the *real* weapon, killing him. However, Dick pulsates a strange aura and after he explodes, there is no sign of Dean and Castiel.

Castiel wakes Dean up and the latter sees they are somewhere different. Castiel, with his original personality apparently back, tells him that they are in Purgatory and are more likely to die then get out. He then disappears, leaving Dean alone and surrounded by monsters.

#### Year in Purgatory

> I am an angel in a land of abominations. There have been things hunting from the moment I arrived. [...] They're Leviathan. I have a price on my head and have been trying to stay one step ahead of them. To keep them away from you. That's why I ran. Just leave me, please.
>
> Castiel upon reuniting with Dean, What's Up, Tiger Mommy?

Some time passes and there is still no sign of Castiel. Dean obsessively tries to find him, even teaming up with a vampire named Benny who knew of a portal that would get them out (which could only be done by a human). Eventually, after scoping out Purgatory and going through several monsters, Dean finds him alive near a stream. Castiel confirms he's as sane as he could be targeted by monsters and the friends reunite.

 File:Supernatural-Whats-Up-Tiger-Mommy.jpg
Dean is eager to leave Purgatory with Castiel, though Benny casts suspicion on the angel by his sudden disappearance earlier on. Castiel admits he did run away and leave Dean alone, but it was only to protect him. The Leviathans wanted him destroyed more than anything because of his actions and he believed leaving Dean would make the Leviathans focus on him rather than on Dean. Because of this, Castiel requests to stay in Purgatory, but Dean tells him there is hope and has Benny inform him of the Purgatory portal to escape, though he is unsure if it will work for Castiel. Despite this, Dean refuses to leave without him as Castiel understands.

 File:LeviathansPurgatory.gif
Castiel travels with Dean and Benny, helping them kill more monsters although at the same time *attracting* more. While Dean doesn't care about this and is angry about Benny at the idea of leaving Castiel, though Castiel agrees with Benny and sees himself as only causing trouble. Benny and Castiel aren't sure that he could cross through the portal, being an angel, but Dean adamantly insists. Soon the group is attacked by Leviathans. Castiel tries to lure them away, but is overwhelmed and nearly killed by one. Benny saves him.

 File:SPN 1355.jpg
In the final stretch, they reach the portal which Castiel sees is reacting to Dean. When Benny's soul is stored safely inside Dean's arm from the spell, they are moments away from the portal but Dean and Castiel are attacked by Leviathans. At the last minute, as Dean reaches out for Castiel, Castiel lets go of him and Dean is transported to Earth without him. Castiel watches, having decided to stay for further punishment for his mistakes.

### Season 8

> Nothing you could've done would've saved me, because I didn't want to be saved. [...] It's where I belonged. I needed to do penance. After the things I did on Earth and in Heaven, I didn't deserve to be out. And I saw that clearly when I was there. I ... planned to stay all along. I just didn't know how to tell you. You can't save everyone, my friend ... though you try.

> Castiel to Dean on why he stayed in Purgatory, A Little Slice of Kevin

In *We Need To Talk About Kevin*, Dean and Sam mention Castiel after Dean returns to Earth with Benny. Dean is vague about Castiel's fate, only mentioning that it got hairy near the end and Castiel "let go." While Dean didn't elaborate, remembering this clearly affected him greatly.

Dean had flashbacks of Castiel in *What's Up, Tiger Mommy?*, remembering finding him and his promise for Castiel to leave Purgatory with both him and Benny. Dean is clearly upset remembering all this and has another flashback where Castiel was struggling to hold onto his arm, while it is unclear what the scenario is, Castiel shouted Dean's name as they are pulled apart.

> You know, there are some in Heaven who still believe, despite his mistakes, that Castiel's heart was always in the right place. [...] I think 'too much heart' was always Castiel's problem.
>
> Samandriel to Dean about Castiel, What's Up, Tiger Mommy?

 File:CasCrowleyBlades.jpg
Castiel finally escapes Purgatory in *A Little Slice of Kevin*. He claims he could not remember how he escaped, a story not received well by a doubtful Dean. Castiel aids the Winchesters and Mrs. Tran in saving Kevin and retrieving the tablet from Crowley. He displays much of his previous abilities, but is weakened quickly now. Castiel saves Kevin and confronts Crowley with his angel blade. Crowley pulls out one of his own and they face off. Castiel displays his wings and goes to smite Crowley who finally retreats, but tries to take the tablet. Castiel smashes it in half and Crowley only gets away with one part. Afterwards. when Dean admits he blames himself for leaving Castiel behind in Purgatory, Castiel tells him he wanted to be left behind in Purgatory as a form of penance.

Moments after, Castiel finds himself in Heaven with an angel named Naomi. It's revealed that his escape was orchestrated by her, claiming many angels in the process. Castiel casually reveals information about the Winchesters and the tablet under control of Naomi. He is sent back to earth without any memory of the meeting and the orders to report into her every so often. Castiel aligns himself with Sam and Dean in searching for the second half of the tablet and fixes Kevin's cut-off finger.

Castiel formally took up the mantle of being a hunter in *Hunteri Heroici*. Dean and Sam were skeptical at first, but both eventually allowed the seraph to join them in a case that Castiel himself found. The Winchesters also guided Castiel on how to pose and act as an effective hunter. Castiel also admits that he fears returning to Heaven: he fears that when he returns and learns just how bad he made it, he will kill himself out of regret. While Castiel is awkward and clumsy at being a hunter, he proves very helpful in solving the case, using his powers to bring Sam into the mind of Fred Jones, a man who is living inside his own mind as it is easier than having to live with the real world. Sam gives Fred a speech about living in a dream world but facing up to your past eventually, Castiel changes his mind and desires to make amends in Heaven instead of running. After the situation is resolved, Castiel removes Fred's powers when he wants to make sure it won't happen again. Castiel does the procedure, leaving Fred in a mentally-distant state, but happy. Even though Sam and Dean have come to accept Castiel as a hunter, Castiel nearly tells them he'll return to Heaven until Naomi teleports him and refuses to allow it. Castiel decides to watch out for Fred for a few days, but also to stop running from his problems.

> **Castiel**: "You don't understand. I have been trying to pretend that I can escape what I did in Heaven, but I can't. All that pain I caused .... I-I have to come back. To make things right.
> **Naomi**: "And you are ... by doing what you're told. Bottom line: Unless I ring my bell, you stay out of Heaven, Castiel."

> Naomi rejecting Castiel's return to Heaven, Hunteri Heroici

 File:CastielChild.jpg
In *Torn and Frayed*, he is shown helping people in need, in repentance for his previous actions. He was ordered by Naomi to rescue a fellow angel Samandriel, who was held captive by Crowley in an abandoned building that he locates with Dean's help. Castiel later retrieves Sam against Dean's wishes. During the attack, Castiel gives Sam his Angel Blade to kill demons with and remains outside until Sam and Dean deal with the wards and demons. He was then able to teleport Samandriel to safety, but not before Samandriel revealed to Crowley the existence of an Angel tablet. Samandriel warns Castiel about this and that "they're" controlling him. His mind wiped, Castiel can't remember Naomi, but before he explain Naomi orders Castiel to kill Samandriel, which he does without hesitation. (Throughout the rescue, Castiel saw vague flashbacks of Naomi inserting a certain device into his eye.) He demands answers from Naomi, who reveals that knowledge of the angel tablet could cause great harm in the hands of a demon. Under Naomi's orders, Castiel claims he killed Samandriel in self-defense and that he is taking his body to Heaven to be put to rest (in actuality so Naomi can determine how much he broke), but his weird behavior and the fact that one of his eyes starts bleeding draws their suspicion that something is wrong and that he is being controlled.

In *Remember the Titans,* Dean desperately prays to Castiel to look after Sam who is not doing so well with his trials. Despite Dean's near-begging, Castiel does not appear or respond.

 File:SPN 0052.jpg
In *Goodbye Stranger,* Castiel has become so indoctrinated to Naomi's control that he has no trouble ruthlessly killing a copy of Dean and is shown to have killed hundreds of others. He is sent to locate the Angel Tablet which is in one of Lucifer's Crypts and to stop Crowley from getting it. His interrogation and killing of the demons involved draws Sam and Dean's attention. Castiel claims to Sam and Dean that he is searching for Crowley's half of the demon tablet and that the demons are searching for a parchment that will allow them to translate the tablet without a Prophet. Castiel tortures a demon for information and after learning the location of the being that is telling the demons where to find the crypts, he kills her before she can reveal the truth to Sam and Dean on Naomi's orders. They find out the hostage is Meg. Castiel is able to get Naomi to let Meg explain the truth as she could be useful and afterwards bandages her wounds. Meg flirts with Castiel about their kiss in a few years ago and subtly tells him she wants to have sex with him, something he doesn't catch on to at first. The group travel to the warehouse where the crypt is located and when Dean orders Sam to stay outside, Castiel tells Sam that he is damaged on a level that even Castiel can't heal.

 File:SPN 1304.jpg
Once inside, Naomi orders Castiel to throw Dean off the trail or kill him, but he is forced to point out the box with the angel tablet in it to Dean as it is angel-proofed. Under Naomi's control, Castiel attacks Dean and tries to kill him, but manages to break free at least somewhat and reveals Naomi's control to Dean. Before he could kills the hunter, Dean tells him that they are family and that he needs him. When Castiel picks up the angel tablet, it severs Naomi's connection with him and all of her control and he heals Dean and explains what happened. However, Castiel senses that for some reason he must keep the tablet safe from Dean as well and disappears with it. Naomi later tells Crowley that Castiel is doing what he is meant to do, which is protect the tablet from all threats. Castiel is later seen riding in a bus with the tablet to an unknown location.

In response to Castiel's departure with the tablet, Naomi starts a search for him, trying to enlist Dean's help in *Taxi Driver* at which time she claims that he is still insane and was simply misinterpreting her orders when he tried to kill Dean. Despite Castiel's behavior, Dean trusts him over Naomi and refuses to believe her.

 File:SPN 0843.jpg
In *The Great Escapist,* Castiel travels between all of the Biggerson's at once, stopping only for very brief periods to throw the angels off of his trail. Its successful until they slaughter everyone in one of the Biggerson's to force him to stop and learn what happened. While he is distracted, Castiel is captured by Naomi, Ion and Esper. Naomi reveals that Castiel has been involved in many atrocities throughout human history, but that his memory of it has been erased because he never follows orders like he is supposed to. Naomi demands the angel tablet, but Crowley arrives, kills Esper, wounds Ion who is revealed to be working with him and drives Naomi off.

> **Castiel**: How---how many times have you torn into my head and washed it clean?
> **Naomi**: Frankly, too damn many. You're the famous spanner in the works. Honestly, I think you came off with a crack in your chassis. You have never done what you're told. Not completely. You don't even die right, do you? Where is the angel tablet, Castiel?
> **Castiel**: In the words of a good friend... bite me.

> Naomi and Castiel's confrontation, The Great Escapist

Kidnapping Castiel, Crowley has realized that Castiel is keeping the tablet close to him in case Naomi ever tries to regain control of him again and shoots Castiel in the gut then painfully pulls the angel tablet out of his body. Before he can do more, he gets a call that Kevin has figured out Crowley's trick and Crowley leaves to deal with the problem, leaving Ion to guard Castiel. Castiel pulls the bullet Crowley shot him with out, overpowers Ion and pushes the bullet through his eye, killing him. Castiel later appears on the road in front of Sam and Dean, severely wounded and weakened and asking for their help.

 File:SPN 0618.jpg
In *Clip Show,* Castiel is slowly recovering from his wound. Dean is furious with Castiel and refuses to forgive him for abandoning them again and not trusting him, despite apologies. As Sam and Dean check out how to cure a demon, Castiel goes to get them food. He gets Dean's favorite beer and porn, along with his pie to appease him. Metatron arrives, revealing that Heaven has degenerated into many warring factions. Naomi is only the leader of one, not all of Heaven as he had previously believed. Metatron suggests Castiel do the trials to seal up Heaven so that they can lock the angels together and force them to sort out their problems while keeping the war from spilling over onto Earth. Castiel agrees after Metatron reveals that as the Scribe of God, he knows the trials even without the angel tablet. Castiel is reluctant after discovering the first trial is to kill a Nephilim, the child of an angel and a human. Castiel hesitates as she is an innocent woman, but when she attacks Metatron, he kills her with his Angel Blade.

 File:SPN 1373.jpg
In *Sacrifice,* Metatron reveals that they must get Cupid's bow as the next trial and Castiel asks him about God. Metatron describes him as like one would expect: larger than life, gruff, a bit sexist and eminently fair. As they wait for Cupid to come to make the man, Dwight, fall in love, Castiel goes through personal ads to try to make it go faster by finding him a candidate. While they are waiting, Naomi arrives with two other angels and captures Metatron. Castiel faces off against them with his Angel Blade, but lets them go when Metatron tells him to. Needing help, Castiel goes to Dean who agrees after Sam insists. Castiel and Dean bring the angel tablet to Kevin to translate the last trial and Castiel scares him into doing it when he refuses. As they watch, a woman named Gail approaches Dwight and makes him and one of his regulars fall in love. Castiel prepares to confront Gail while armed, but Dean convinces him to talk first. Gail is worried about the state of Heaven and agrees to give them her bow if they really think they can calm it down, but Castiel must cut it out of her hand. Kevin contacts them to let them know that while he has found the trials, he doesn't see anything about killing a Nephilim or the bow of a Cupid. At that moment, Naomi arrives and though Castiel goes to fight her, she insists she just wants to talk and Dean gets him to hear her out. Naomi tells Castiel that she has learned from Metatron's mind that what he is doing isn't going to seal Heaven up, it will instead expel all angels from it permanently. She expresses remorse for her actions, telling Castiel and Dean that angels were meant to protect humanity and lost sight of that somewhere along the way.

Naomi offers to hear Castiel out if he really wants to return to Heaven before disappearing. When Kevin can't confirm what Naomi told them through the angel tablet, Castiel doesn't believe her, but transports Dean to the church where Sam is curing Crowley before departing for Heaven. There he finds Naomi dead with her own torture device impaled in her brain and is captured by Metatron who reveals that she was telling the truth. Metatron takes Castiel's Grace as the last ingredient for the spell he is working and sends him to Earth, but not before telling him that he is now human and Metatron wants him to live a human life, die, come to Heaven, find him and tell him about that life. On Earth, Castiel watches in horror as all the angels begin to fall to Earth as Metatron's spell takes effect.

In *I Think I'm Gonna Like It Here,* Castiel has landed in Colorado and nearly gets run over by a truck. Castiel is left stunned by the cuts on his palms from dodging the truck as he has never experience the types of injuries mortals get before and gets a ride from the driver to a gas station. Reluctantly taking money the driver gives him, Castiel goes to call Dean but meets a Fallen Angel named Hael who is looking for guidance. Castiel suggests Hael take advantage of the new life given to her and go see the Grand Canyon that she claims to have created. Deciding to go with her, Castiel first calls Dean and confirms that Ezekiel is a good guy and can help and then is convinced to come help Dean instead of Hael. She knocks Castiel out and kidnaps him, revealing that she plans to possess him as he is strong and her vessel is weak and deteriorating. In order to stop her, Castiel puts on his seatbelt and then crashes the car, incapacitating Hael while surviving with minor injuries. Castiel takes her Angel Blade and declares his intent to guide all angels in their new lives on Earth, but when Hael threatens to broadcast his location to every angel looking for him if he doesn't say "Yes", Castiel kills her. Later, Castiel starts to dry-clean his bloody clothes at a laundry mat, but needing food and water, steals new clothes and buys candy and a water bottle instead.

In *I'm No Angel,* Castiel travels towards the bunker, living in homeless camps and trying to avoid angels. After being confronted by and killing an angel one night, Castiel has himself warded against angels being able to locate him with a tattoo. In response, the angel Bartholomew sends rouge Reapers after Castiel. While looking for food in a dumpster, Castiel meets April Kelly, not knowing that she is possessed by a Reaper and goes home with her. April cleans the wound he got from the angel he encountered and they have sex, but while searching for his Angel Blade the next morning, she reveals herself as a Reaper, ties him up and tortures him. Castiel tells her how he didn't know about Metatron's spell and that he doesn't know how to reverse it, but that his Grace was the final ingredient and thus he may be the key to the reversal. When Sam and Dean show up, the Reaper kills him with the Blade. After Dean kills the Reaper, he mourns his friend but Ezekiel takes control of Sam and resurrects Castiel and Dean claims that he made a deal with the Reaper not to kill her if she resurrected him then killed her anyway. Castiel moves to the Bunker with Sam and Dean and is excited by the Bunker's abundance of food and other human necessities and tells a shocked Sam and Dean how he had sex. Castiel sits down to eat, but after learning from Ezekiel that Castiel must leave because the angels are after him, Dean reluctantly tells him so as Ezekiel will be forced to leave Sam and flee otherwise and Sam will die.

> There really is a lot to being human, isn't there? [...] There's more to humanity than survival. You look for purpose, and must not be defeated by anger or despair. Or hedonism, for that matter. [...] I do see now how difficult life can be and well how you two have led it. And I think you'll be great teachers.

In *Heaven Can't Wait*, While working as a sales associate at a gas station- and also serving as a baby-sitter for his boss, Nora, although he initially assumed it was a date. Castiel tries to be happy as a human, but struggles to fit in and remains depressed. Castiel calls the Winchesters for help after two people in his area simultaneously combust. With Dean's aid, Castiel determines that the victims were killed by a Rit Zien, a class of angel healers that kill mortally wounded angels. Castiel then goes on what he believes is a date but turns out to be a babysitting gig, growing worried when the baby, Tanya, gets a fever and won't stop crying. Before he can take Tanya to the hospital, the Rit Zien, Ephraim approaches him, having detected his pain. Castiel tries and fails to banish the rogue angel, but before Ephraim can kill him, Dean arrives and tosses him an angel blade, allowing Castiel to kill Ephraim. Castiel then miserly goes back to his normal life at the gas station, beginning to wonder if he should help the angels get back in Heaven.

You're just ... shoved out kicking and screaming into this human life without any idea why any of it feels the way it feels, or why this confusion, which feels like it's ... a hair's breadth from terror or pain.

In *Holy Terror*, Castiel investigates mysterious angel deaths with Sam and Dean. After "Ezekiel" orders him to send Castiel away, Dean does, explaining partially what happened. Feeling helpless, Castiel decides to pray for aid, when his prayers are answered by Muriel, a neutral angel in the war, who explains that the current conflict is between factions led by the angels Bartholomew and Malachi, but the two are captured by Malachi and his ally Theo. Muriel is killed while Malachi tortures Castiel for information about Metatron, revealing that Ezekiel is dead. When Castiel is left alone with Theo, Theo begs him to help him defect to Metatron who he believes Castiel is still working with. Castiel tricks the misguided angel into releasing him, then slits his throat with an angel blade and steals his Grace, restoring his own powers. Castiel then smites Theo and fights his way out. Disgusted with himself but believing it necessary, Castiel calls Dean to warn him that Ezekiel is dead and thus couldn't have been the angel that helped him save Sam.

In *Road Trip* Castiel, wearing a new suit and trenchcoat, arrives at the bunker to find the main room trashed and a distraught Dean. Dean explains what happened and how he intends to hunt down and kill the angel possessing Sam for revenge even though it will kill Sam. Castiel however, comes up with the idea of having Crowley do the same thing he did to Samandriel to try to bring out Sam's mind so he can expel the angel. Enlisting Crowley's help, the three take a car that Castiel stole as he can no longer teleport and find the angel. The angel overpowers Dean, but while he's distracted, Castiel knocks him out. After confirming that the angel healed Sam enough that he can finish the job, Castiel watches with Dean as Crowley tortures the angel and follows Dean out when he can't watch anymore. Sympathetic with Dean and forgiving him for kicking him out, Castiel comforts him until Crowley calls them back as he has managed to activate the angel's "factory settings." Castiel is furious when the angel identifies himself as Gadreel, blaming him for everything that has gone wrong in the world. However, Gadreel regains control, telling them that he can withstand the torture for a very long time and they can't stop him without killing Sam. Desperate, Dean asks Castiel to possess Sam to make him aware of the situation, but Castiel is unable to as he would need Sam's permission to do so. When Crowley offers instead in exchange for his freedom, Castiel is reluctant, but removes Sam's anti-possession tattoo so Crowley can possess him. The plan works and Sam expels Gadreel. After Crowley returns to his body, Castiel notes the appearance of Abaddon and the three leave Crowley to deal with her. A safe distance away, Castiel heals Sam's injuries from the torture and some more of the damage the Trials did to him telling him that while he will have to do it in stages and over time, he will be able to finish Sam's healing. Castiel stands a respectful distance away as Sam and Dean speak about Dean's actions and remains with Sam as Dean leaves, alone.

In *First Born*, Castiel is staying with Sam in the bunker and has nearly healed him fully. He is also upset about the fact that he has lost the ability to enjoy human food. However, he discovers that some of Gadreel's grace is still inside Sam and is slowly disappearing every time Castiel heals him. Reading a book and file from the Men of Letters left, Castiel learns that the Men believed that if the grace was extracted, it could be used to track the angel it belonged to. Sam and Castiel begin a procedure to remove the grace, but though it proves dangerous as Sam's body starts to revert to its state before Gadreel possessed him, Sam insists that they continue. With Sam's condition deteriorating as they need more grace then can be safely taken, Castiel chooses to finish healing him rather than take the rest of the grace, destroying the last of the grace inside Sam. Castiel explains that his brief humanity caused him to understand that its not worth it to sacrifice others for the sake of what you need and that he understands where Sam is coming from wanting redemption for his acts as he also wants that, but its not worth his life. Sam and Castiel later use the grace they extracted to try the spell, but it proves not to be enough. Telling Sam that he believes that Metatron is the key to setting things right, Castiel sets out to locate him.

> Sam, when I was human, I died. And showed me that life is precious and must be protected at all costs. Even a life ... as pig-headed as a Winchester's. [...] Sam. I want Gadreel to pay as much as you do. But nothing is worth losing you. You know, being human didn't just change my view of food. It changed my view of you. I mean, I can relate now to how you feel.[...] The only person who's screwed up more consistently than you ... is me. And now I know what that guilt feels like. And I know what it ... I know what it means to feel sorry, Sam. I am sorry. [...] You know old me. I would've just keep going. I would've jammed that needle in you deeper until you died because the ends always justified the means. But what I went through ... well, that PB & J taught me that angels can change. So ... who knows? Maybe Winchesters can too.

In *Captives*, looking for information on Metatron, Castiel tracks down a follower of Rebecca, a friend of Metatron's. The follower reveals however that Rebecca had set up a faction called the Penitents who coexisted peacefully with humanity before all but him were slaughtered by Bartholomew and his followers. Leaving the other angel alone, Castiel is captured by angels working for Bartholomew. To his surprise, despite having his angel blade taken away, Castiel is warmly greeted by Bartholomew who was a subordinate and friend of his in Heaven. Bartholomew invites Castiel to join him in uniting the angels, believing that together they can unite all of the angels under one rule. Bartholomew also has the resources to track Metatron when he appears on Earth and offers Castiel his help with tracking him. However, when Bartholomew captures Rebecca's follower, Castiel is horrified by the angel's torture. When asked to kill the angel, Castiel refuses, saying he would rather die than needlessly kill another angel, wanting peace between the angels, not more war. To Castiel's horror, Bartholomew kills the angel then attacks Castiel himself. Castiel overpowers Bartholomew, but declaring his refusal to kill, Castiel lets him go and starts to leave. When Bartholomew attacks Castiel while his back is turned, Castiel is forced to kill his brother in self-defense. Visiting Rebecca's grave, Castiel is stunned when some of Bartholomew's followers approach him to lead them in a more peaceful way of existing.

In *Meta Fiction*, Castiel follows a strange sound to find the Horn of Gabriel and a bunch of dead angels. He finds Hannah alive and heals her, learning that it was Gadreel who killed all of the angels when they refused to join Metatron. Castiel refuses to lead the angels against Metatron and leaves. He is shocked when Gabriel approaches him for help with dealing with Metatron and the two start heading towards the Bunker with Gabriel trying to convince Castiel to help the angels against Metatron, saying that Castiel has been God more than God himself has been. While at a gas station to get more gas for Castiel's car, Castiel and Gabriel are attacked by angels working for Metatron. Gabriel tells Castiel to leave and lead the angels against Metatron while he sacrifices himself to hold the angels off. However, Castiel realizes that it's just an illusion after noticing that a rip in his trenchcoat is no longer there. Castiel proves it by stabbing Gabriel to no effect. Gabriel admits its not real, but that what he said about Castiel needing to lead the angels is true. Castiel comes out of the illusion to find himself tied down in Metatron's office in Heaven. When Castiel doesn't understand a reference, a frustrated Metatron gives Castiel all of his knowledge about popular culture and explains that he wants Castiel to lead the angels against him as he wants Castiel to be the villain in his "story." In return, he offers Castiel an endless supply of grace to replace his stolen burning out grace. Castiel refuses and before they can discuss it anymore, an angel alerts Metatron that Sam and Dean have captured Gadreel. Metatron trades Castiel for Gadreel, blowing out holy fire and easily overpowering Sam and Dean. Afterwards, Castiel tells Sam and Dean he is on board with stopping Metatron and is angry to find out that Dean has taken on the Mark of Cain. He warns Sam to keep an eye on Dean. Castiel also shows his new understanding of references to the Winchesters who are surprised. The next day, Castiel uses the Horn of Gabriel to call a group of angels to him to become their new leader.

In *Bloodlines*, Castiel contacts Dean with the information that he has gotten a lead on Metatron causing Sam and Dean to drop the case they are working on and take off to meet him.

In *King of the Damned*, Sam and Dean meet Castiel at his new headquarters where he is the leader of most of the angels on Earth. He reveals that having killed Bartholomew and with Malachi dead at Gadreel's hands, all the angels have been turning to him for leadership in the war to retake Heaven. Castiel's men have captured an angel named Ezra who works for Metatron and he wants Sam and Dean to interrogate him. Sam and Dean are able to trick Ezra into revealing that Metatron has an elite ground force and that there is a portal to Heaven that Metatron moves around and controls. Before they can learn more, Ezra is murdered and Crowley calls Sam and Dean to offer the location of the First Blade and Abaddon. Before Sam leaves, Castiel asks him his opinion on Gadreel who Sam believes might have been misunderstood before he murdered Kevin. Castiel sets up a meeting with Gadreel, but comes under attack from two angels that he kills. Castiel later meets with Gadreel again, telling him that Metatron has no honor and asking Gadreel to become his spy. Gadreel refuses due to his own honor not letting him abandon the cause he has dedicated himself to, but Castiel tells him to think on it and leaves.

> They had no leader, and they insisted on following me. [...] Bartholomew is dead. Malachi was murdered by Gadreel and with Metatron as powerful as he is now, I needed to do something. [...] Dean, this angel-on-angel violence has to end. Someone has to say enough.

In *Stairway to Heaven*, after an angel named Oran kills himself and an ice cream shop full of people including an angel named Ester, Castiel, Sam and Dean investigate. Castiel is stunned as Oran was one of his men and he killed everyone in Castiel's name. Castiel insists that he didn't order the attack though Dean doesn't believe him. While Dean investigates looking for more angels that might be suicide bombers, Castiel and Sam start chasing down a missing angel named Josiah who they come to believe may be the one who killed Ezra and a traitor. During the trip, Castiel is stunned to learn that Abaddon is dead and is worried about the effect the Mark of Cain is having on Dean. Tracking Josiah to Pray, Montana, Sam and Castiel find a building where the door to Heaven apparently is. Passing tests based on pop culture, they enter a room only to find that its one of Metatron's tricks and that Josiah was caught in a holy fire trap meant for Castiel. Castiel offers to heal Josiah, but he dies rather than owe Castiel his life. Returning to his base, Castiel finds that Dean apparently killed the Reaper Tessa who was working for him with the First Blade though Dean tells him that Tessa killed herself. Before they can talk more, Metatron contacts Castiel's followers, offering them amnesty if they abandon Castiel and insisting that Castiel ordered the bombers, only cares about himself and the Winchester and tells them about Castiel's dying grace. Metatron's transmission makes Castiel's followers doubt him and Hannah demands he kill Dean in punishment for killing Tessa to prove himself. When Castiel refuses, all of his followers abandon him. Castiel returns to the Bunker with Sam and Dean where the three become determined to stop Metatron and are shocked when Gadreel shows up to offer his help, confirming that Metatron was behind the suicide bombers and asking for a second chance. Dean pretends to give it to him then slashes Gadreel across the chest with the First Blade, seriously wounding him and causing Sam and Castiel to restrain Dean.

In *Do You Believe In Miracles?*, after locking Dean in the Bunker's dungeon, Sam and Castiel go looking for Gadreel who has fled in fear of his life and find him. Despite Gadreel telling Castiel not to heal him due to his weakening grace, Castiel does so anyway and Gadreel reveals that Metatron's plan is to convert humanity into worshiping him instead of God. After Sam and Castiel tell him that Dean used the First Blade to injure him, Gadreel insists that Dean is their best chance to kill Metatron and reveals that the source of his power is the Angel Tablet. Gadreel tells them that if they break Metatron's connection to the tablet, he will be a regular angel again and killable. Castiel decides to sneak into Heaven with Gadreel to find the tablet and has Gadreel pretend that Castiel is his prisoner to get through the portal, getting the idea from *Star Wars.* In Heaven, Castiel and Gadreel are locked in Heaven's dungeon by Ingrid and Hannah who see through their deception. Castiel tries to convince Hannah to help them stop Metatron, but she refuses to believe him as he promised an end to angel deaths. Gadreel suddenly speaks of his desire to redeem himself, being the only thing he focused on since his first imprisonment in the dungeon for thousands of years and how he lost sight of the angels' true mission; to protect humanity no matter the cost to themselves. Gadreel warns Castiel and Hannah away and then kills himself, using the same sigil the suicide bombers used to create an explosion to free Castiel.

Gadreel's sacrifice convinces Hannah to rejoin Castiel in taking down Metatron. Taking Ingrid captive, Castiel and Hannah try to force her to tell them where to find the tablet, but when she refuses, Castiel orders Hannah to take her out and searches on his own. Eventually Castiel finds the angel tablet in Metatron's typewriter and smashes the tablet, removing Metatron's incredible powers. When Metatron flees an attack from Sam back to Heaven, he finds Castiel sitting in his chair and chains him down. Metatron taunts Castiel with the fact that he has killed Dean, causing Castiel to fail in his attempt to save him by shattering the tablet. Metatron calls all angels "sheep" who will follow him where he wants and shows disgust for humanity. Metatron prepares to kill Castiel, telling him that the angels will never believe him because Castiel can never spin a good story. Castiel agrees, saying that Metatron can however and reveals that he used the equipment in Metatron's office to broadcast the entire conversation over "angel radio." Before a horrified Metatron can react, Metatron's enraged followers storm his office, overpower Metatron and free Castiel. Castiel however locks Metatron in Heaven's dungeon rather than kill him, something Hannah tells him is the act of a true leader. While the angels now once more want to follow Castiel in rebuilding Heaven, Castiel informs Hannah he wishes to be a normal angel again and not a leader. Hannah reminds him that he will die soon when his grace burns out unless he can replenish it, leaving Castiel contemplating the future.

 File:Normal spn1001 0863.jpg
In *Black*, Sam finds what he think may be a clue – a man called Drew Neely who had killed his family and disappeared three years earlier has been found dead. Sam theorizes that Neely was possessed by a demon, who may have possessed Dean and left Neely's body to die. Sam calls to share the news with Castiel, who is anxious for news of Dean. Picking up that Castiel is seriously unwell, Sam backtracks and tells him not to worry, that the clue probably isn't anything. Later Hannah visits Castiel. She tells him that rebuilding is proceeding in Heaven; Metatron is in jail, and reconciliation amongst the angels is proceeding. However, some angels remain on Earth, and recently two of them – Daniel and Adina – killed an angel who tried to get them to return to Heaven. Hannah asks for Castiel's help in finding them, and he agrees. Hannah and Castiel travel to find the two rogue angels. Hannah confronts Castiel about his fading grace, but he angrily rebuts the implication that another angel die for him to get more grace. They find Daniel and Adina, who want to stay on Earth, having found much there they enjoy. Hannah persists – that they must return to Heaven; Heaven needs rules to operate. A fight ensures during which Castiel has to kill Daniel to save Hannah. Adina escapes. Hannah continues to insist to Castiel that Heaven needs rules, but Castiel says that the chaos on Earth can produce good things – art, hope, dreams, love – that Hannah points out are "human things."

In *Reichenbach*, after Hannah heals him, Castiel and Hannah work their way towards North Dakota to meet with Sam who informs Castiel that Dean is now a demon. Castiel's grace continues to fade and he falls asleep at the wheel, causing them to crash. After spending the night at the tow truck driver's house, Castiel awakens to find that Hannah has traveled to Heaven to talk to Metatron about Castiel's grace. Castiel walks in on Metatron claiming that there is some left and he will give it to her in exchange for being released. However, Castiel stops her, accepting his fate. Before he leaves, Metatron claims to Castiel that there really is some of his grace left, but that when he escapes he will destroy everything in his revenge.

In *Soul Survivor*, Castiel and Hannah head towards the bunker to help Sam cure Dean. Along the way, they stop at a gas station where they are ambushed by Adina. In his now severely weakened state, Castiel proves no match who the other angel who beats him badly before leaving him to kill Hannah. Castiel is unexpectedly saved by Crowley who takes Adina's grace and kills her. At Crowley's insistence, Castiel reluctantly takes in Adina's grace and is restored to full health. Crowley asks Castiel to help deal with the Dean situation in return for his help even if it means killing him. Castiel finally arrives at the bunker in time to keep Dean from killing Sam and restrain him. Castiel watches as Sam completes the cure and watches anxiously to see if it works, ready to kill Dean if it doesn't. The cure works and Dean becomes human again to Castiel and Sam's relief. Castiel tells Sam he is temporarily back to full strength again and that while Dean is no longer a demon, the Mark of Cain is still a problem that needs to be solved. He consoles Dean over his actions as a demon and suggests he take time off since things are quiet now. File:SPN 0614.jpg  In *Girls, Girls, Girls*, Castiel and Hannah continue their search for rogue angels to send back to Heaven with Hannah starting to enjoy human things and feelings, displaying an attraction to Castiel that he rebuffs. As they leave the motel they are staying at, Castiel and Hannah are confronted by Joe Johnson, husband of Hannah's vessel Caroline Johnson. Hannah pretends to be having an affair with Castiel to give closure to Joe, but is disturbed by her actions and feelings. Castiel tries to comfort Hannah by telling her of his interactions with his own vessel, Jimmy Novak and how the mission is more important than their vessels or their families. Hannah later reveals to Castiel that she intends to return to Heaven so that Caroline can return to her normal life. After Hannah leaves, Castiel returns Caroline home and inspired by Hannah's actions with her vessel, looks up Jimmy on the Internet to discover that his family is still looking for him.

In *The Things We Left Behind*, Castiel tracks Claire Novak to a group home where he pretends to be Jimmy in order to see her. Claire is upset by his presence as she recognizes him as Castiel, not Jimmy, especially when Castiel tells him that Jimmy is dead and in Heaven. When Castiel asks what he can do to help, Claire asks him to pose as Jimmy and sign her out, but it doesn't work as Jimmy has been gone so long so Castiel breaks her out instead. While Castiel tries to take Claire with him, she runs away and he calls in Sam and Dean to help find her. Sam and Dean tell him stories about their own turbulent history with their father. Dean, knowing he might become a demon again due to the Mark of Cain, asks Castiel to kill him if that happens. Sam and Dean are eventually able to help Castiel track Claire to a man named Randy. They arrive to find Randy tied up by loan sharks and one trying to rape Claire. Castiel rescues her, but while he, Claire and Sam are outside, Dean falls under the Mark's influence once more and slaughters Randy and the loan sharks to everyone else's horror.

In *The Hunter Games*, Sam and Dean question Castiel about the possibility of a cure for the Mark of Cain, but he informs them it would take a great power to remove it and while the demon tablet might've been able to help them, it's missing. Reluctantly, Castiel suggests calling upon Metatron for help instead and gets Ingrid to bring him to them. Metatron tells them that they need the First Blade for the cure, causing Sam and Dean to call upon Crowley to get the First Blade. At the same time, Castiel visits Claire in a hotel to discover that she is leaving and is trying to cut all ties with him as she blames him and Dean for her father's death. While waiting for Crowley to get back to them, Castiel suggests that Dean talk to Claire and try to convince her of the truth about what happened with Randy. After finding out that Crowley won't give them the First Blade until they have the entire cure, Dean locks himself in the bunker's dungeon with Metatron and tortures him for information when he refuses to tell him the rest without a lot of little favors. Castiel manages to blast the door down in time to stop Dean from killing Metatron and takes him back to Heaven, seeing it as too dangerous to keep him in the bunker with Dean. After returning Metatron, Castiel senses that Claire wants to talk to him and tracks her down. Claire tells him that while she needs to be on her own, she wouldn't be against keeping in touch with him and tells him that he looks better in a tie.

In *The Executioner's Song*, Castiel continues his search for Cain by interrogating a captured demon. After the demon tells him of a location that Cain has been seen at, Castiel kills him. Searching the location, Castiel finds a massive graveyard and calls Sam and Dean to inform them of it and they tell him how Cain kidnapped serial killer Tommy Tolliver. Castiel confirms Tommy is dead and tells the brothers he will come to them before Cain himself appears. Cain is unconcerned about Castiel's angel blade and tells he is not his target while revealing that he has fallen back under the influence of the Mark of Cain. Believing that his bloodline is tainted, Cain intends to wipe it out despite it being legion. Castiel asks Cain about the cure but is told there isn't one and how Dean will succumb again before he leaves. Castiel then meets with Sam and Dean at the bunker and after explaining what is going on, Dean decides to kill Cain despite the inherent dangers in him using the First Blade again. After getting Crowley to agree to help them, the group travels to the house of Austin Reynolds, Tommy's 12-year-old son where Castiel is quickly knocked out after his white light proves completely ineffective against Cain. Despite Castiel's failure, Sam and Crowley succeed in using an Illusion Spell to trick Cain into a devil's trap. Afterwards, Dean goes to confront Cain alone, telling the others that they may have to kill him if he returns as a demon and Castiel keeps Sam from following. After Dean kills Cain, he comes out normal and hands Castiel the First Blade instead of Crowley, stunning the demon with his lies. Castiel later tells Sam and Dean that he has hidden the First Blade somewhere, to Dean's relief and Sam privately informs him that Dean is in trouble.

During *Inside Man*, Sam realizes that Dean is getting worse and calls Castiel to help him find a cure for the Mark immediately. While Castiel is initially reluctant, he eventually agrees and takes Sam to the portal to Heaven to retrieve Metatron once more. However, Hannah, in a male vessel appears to block the way. While she is happy to see Castiel again and that for now at least his grace is alright, Hannah refuses to let them get Metatron, knowing that he will demand his release in exchange for his help which can't happen. Castiel and Sam are forced to leave when Hannah calls in three more angels to keep them from getting into Heaven. Needing another way to get at Metatron, Sam and Castiel use psychic Oliver Price to perform a séance and contact Bobby in Heaven for help in breaking Metatron out. Castiel directs Bobby in how to break out of his Heaven and to open the portal from the Heaven side. After Bobby opens the portal, Castiel enters Heaven where he meets with Bobby who demands to know what is going on. After informing him of the situation, Castiel and Bobby reach the dungeon where they reluctantly release an amused Metatron. Castiel takes Metatron back to Earth where he removes his grace and has Sam shoot him in the leg as a demonstration of his new mortality. Castiel demands the cure or he will have Sam kill Metatron, causing him to admit he'd been lying all along and that he knows of no cure. Metatron tells them that the Mark is God-level or Lucifer-level power and its not even covered on the demon tablet. While Sam doesn't believe Metatron, Castiel is able to tell that he is actually telling the truth and tells Sam to kill him. However, Metatron quickly reveals that there is some of Castiel's grace left and offers to take him to it to get Castiel to spare his life. Castiel reluctantly agrees and leaves with Metatron to find his grace.

In *Book of the Damned*, Castiel continues his road trip with Metatron to find his grace, getting increasingly annoyed with Metatron's antics as he experiences his new humanity resulting in Castiel punching him in the face at one point. He gets more annoyed as each of the safe houses they check come up empty. As they leave a diner where Metatron has gastrointestinal issues as he is lactose intolerant, they are attacked by an angry Cupid who nearly kills Castiel before Metatron kills him. However, this act doesn't endear him to Castiel who simply continues the trip. Reaching a library, Castiel is able to sense his grace, but its location is hidden from him. Metatron reveals that he doesn't actually know where it is as he had another angel hide it in case of torture but he has clues hidden to find the book it is in. Castiel and Metatron locate the first clue, "what's the maddest thing a man can do" and look for the book titled that. As they search, Metatron questions Castiel about what he will do once he finds the remaining rogue angels and gets them to return home as Heaven is in order now under Hannah's leadership. Castiel doesn't have an answer and is surprised when Metatron stuns him with a spell. Metatron reveals that he is actually there for the demon tablet as well as Castiel's grace and retrieves the tablet while Castiel realizes that they are looking for quotes in books, not titles as he'd thought. Using the knowledge of popular culture that Metatron gave him, Castiel is able to find his grace in a copy of *Don Quixiote*. Seeing Castiel has already got his grace, Metatron takes the demon tablet and flees. Castiel ingests the remnants of his grace and that combined with Adina's grace restores him to full power and his old status as a Seraph. However, his wings remain broken. Returning to the bunker, Castiel informs Sam and Dean of the return of his full power and lies to Dean about how he got it back, telling him that Hannah got it out of Metatron. Castiel finally meets Charlie Bradbury who is excited by the meeting and jokingly asks him to heal her carpal tunnel. Taking her seriously, Castiel heals the affliction and even Charlie's bullet wound causing her to declare them best friends. Afterwards, Castiel celebrates his return with his friends.

In *Angel Heart*, after Claire is knocked unconscious, Castiel is called as he is in her emergency contacts on her cell phone. Castiel calls in Sam and Dean to help him deal with her and they discover that she is looking for her missing mother. Feeling responsible as he'd promised Jimmy he'd look after his family, Castiel insists on helping find Amelia before they discover Claire gone. Recalling that Claire mentioned that a man named Ronnie Cartwright was the last to see Amelia, Castiel and Dean go to interrogate him while Sam goes to Claire's motel to cut her off. Castiel gets worried when Dean gets rough with Ronnie, but they learn that he sent Amelia to a faith healer named Peter Holloway. Ronnie tells them that Holloway is the real deal, having healed his blindness, but that he quit after seeing Holloway cut the people sent to him. Dean and Castiel go to Claire's motel where Sam is hacking Amelia's credit card records. After learning of Ronnie's murder, Dean, Castiel and Claire go to investigate it, but not before Castiel tells Sam that Dean is getting worse. At the scene, Castiel determines that the fatal wound was caused by an angel blade but that it seems to be larger and has left three strange markings that he is unable to identify meaning that they are dealing with a fellow angel. After Sam identifies Holloway's location from county records and Amelia's credit card records, he and Castiel go to the farm, leaving Dean behind with Claire due to his worsening condition.

 File:Normal spn1020 2560.jpg
While Sam searches the house, Castiel searches the barn and finds Amelia. He is able to wake her up and she is extremely happy to see him, despite recognizing that Jimmy is no longer in his body. While Castiel is remorseful over his inability to protect her, Amelia assures him that as long as Claire is safe, he kept his promise. Castiel is unable to heal Amelia's injuries, something that disturbs him as that has never happened before. When Dean and Claire arrive to help, Castiel and Dean leave mother and daughter alone. The two find Sam with him and Dean (who discovered earlier) informing each other that Holloway, who's real name is Tamiel is actually a Grigori. Castiel is shocked, as he believed the Grigori were supposed to have been wiped out millennia earlier but Sam states that wasn't the case as some survived. When Sam tells him what the Grigori have been doing, Castiel realizes that the victims have been fed on and becomes disgusted before he angrily questioned where the abomination was. Finding the house empty, Castiel and the Winchesters rush to the barn where they find that Tamiel has killed Amelia. The three quickly engage Tamiel who proves too strong for them, even with Castiel's fully restored strength and he is at Tamiel's mercy. Before Tamiel can kill Castiel, Claire catches him off-guard stabs him through the back with his own angel sword, killing him. The next day, Castiel, Sam and Dean say goodbye to Claire, sending her to Jody until she can get on her feet. Claire has forgiven Castiel for his role in her father's death and keeps a stuffed animal Castiel got her for her birthday and asks Dean to look after him, saying Castiel has been through enough.

During *Dark Dynasty*, needing Rowena MacLeod to decode the *Book of the Damned* with Charlie's help and do it in secret, Sam calls upon Castiel to act as her guard. Castiel and Charlie are both unhappy to have to work with Rowena and keep it from Dean, but both ultimately agree for the sake of Dean. Castiel keeps an eye on Rowena and along with Charlie, gets annoyed by her incessant comments. Eventually Charlie asks to leave for a little while, but Sam finds it too dangerous with the Styne Family out there so Castiel locks Rowena in a backroom to give Charlie the privacy she asked for. However, while Castiel is busy doing that, Charlie leaves and Castiel quickly alerts Sam.

In *The Prisoner*, Castiel is relieved when Sam returns but is upset to learn of Charlie's death. Sam tells him that they are ending the attempts to find a cure and are killing Rowena. Castiel is more than happy to hear that as Rowena has greatly annoyed him. However, Sam receives an email from Charlie post-mortem with information on how to decode the *Book of the Damned* and decides to continue on. While Sam goes after Crowley as Rowena demands, he sends Castiel after Dean using a low-jack he placed on the Impala. Castiel later arrives at the Styne compound to find everyone brutally massacred by Dean and informs Sam of that along with the fact that Dean is heading back to the bunker. Castiel arrives at the bunker to find that Dean has killed the Stynes there, murdering Cyrus Frankenstein as well despite him being just a boy. Castiel is horrified as in the past, Dean would've let Cyrus go and tries to convince Dean to stop and let them cure the Mark of Cain, saying that while Dean will fight the Mark for as long as he can, one day he will lose control and Castiel will be there to watch him destroy everything. Dean refuses to stop and when Castiel attempts to keep him from leaving, Dean attacks him. Castiel doesn't fight back and is badly beaten. Dean nearly kills Castiel with his own angel blade, but ultimately leaves him alone and warns him that if he and Sam come near him again, he will kill them.

> Maybe you could fight the mark for years. Maybe centuries, like Cain did. But you cannot fight it forever. And when you finally turn, and you will turn ... Sam and everyone you know, everyone you love, they could be long dead. Everyone except me. I'm the one that will have to watch you murder the world. So if there's even a small chance that we can save you, I won't let you walk out of this room.

 File:CastielAttackDogSpell.jpg
In *Brother's Keeper*, a healed Castiel talks with Sam about continuing to chase Dean despite the fact that with the Mark, he's unstoppable. Castiel goes with Sam to confront Rowena armed with witch-killing bullets, but she is unthreatened as they need her to decode the *Book of the Damned* and cast the spell to remove the Mark. She offers a new deal: her freedom and Nadia's Codex in exchange for removing the Mark and Sam agrees despite Castiel's reservations. Reading the *Book*, Rowena discovers they need a piece of the apple from the Garden of Eden, a piece of the Golden Calf idol, Dean's hair and the blood of the person she loves. When Rowena claims not to love anyone, Castiel reads her mind and discovers she loved a boy named Oskar centuries ago. While Sam goes after Dean following a call from Rudy, Castiel summons Crowley and asks his help in getting the ingredients. Crowley reluctantly agrees and gathers the needed ingredients, including Oskar who Rowena had made immortal. Rowena is furious with them for what they're making her do, but she kills Oskar and casts the spell to remove the Mark of Cain. While she is successful, unknown to the three of them, she also unleashes Amara. To their surprise, Rowena then escapes her chains, immobilizes them and escapes with the *Book of the Damned* and Nadia's Codex. However, before she goes, she casts the Attack Dog Spell on Castiel, making him draw his angel blade and attack Crowley.

### Season 11

 File:SPN 0255.jpg
In *Out of the Darkness, Into the Fire*, Castiel has regained control himself, but is still under the effects of Rowena's spell. Castiel remembers attacking Crowley who is hindered by Rowena's spell on him. Castiel eventually stabs Crowley in the back with his angel blade, but not before Crowley smokes out which Castiel realizes when remembering what happened. Found by a couple of farmers, Castiel flees and is horrified when he talks to Dean on the phone and learns of the release of Amara. Unable to find the portal to Heaven, a desperate Castiel prays for help and Efram and Jonah appear. However, when they chain him up in a warehouse, Castiel realizes that they don't intend to help him, which Efram confirms.

 File:SPN 1288.jpg
In *Form and Void*, Castiel is repeatedly tortured for information he doesn't have on Metatron, but the angels don't believe him. Finally, Hannah shows up in her male vessel and puts a stop to the torture, but Castiel tells her to keep him restrained due to the effects of Rowena's spell. At Castiel's request, Hannah tries to heal him and remove the spell, but can't because of the power of it. Castiel explains the release of the Darkness to Hannah to her horror, but when she starts questioning him about the location of the Winchesters, Castiel realizes that its all a trick and Hannah is just trying to get information out of him as well. Hannah reluctantly explains that after Metatron's escape, a lot of angels now hate him again but is interrupted by Efram before she can answer his question of whether she hates him too. Jonah then starts to "hack" Castiel similar to how Crowley and Naomi do it, but while Efram and Jonah are arguing with Hannah, Castiel falls back under the influence of Rowena's spell and breaks free. Castiel quickly overpowers and kills Jonah in self-defense, but Efram kills Hannah for interrupting. Using Hannah's body as a shield, Castiel angrily attacks Efram for his actions and a fight breaks out between them. Eventually, Castiel overpowers and kills him, but is left horrified by the deaths of the three angels, one of which was his friend. He's later found on the ground in the Bunker in pain and asking for Sam and Dean's help.

 File:Spn1103 2651.jpg
In *The Bad Seed*, Castiel is chained to the floor of the Bunker while Sam and Dean try to find a way to help him since he's a danger while under the spell. They realize that rather than killing Castiel as it would a human, the spell has dug deep and is affecting him badly and that Rowena is the only one who can remove it. Castiel is further hurt by hearing "angel radio" from which he learns that the angels are doubling their efforts to find Metatron who the Winchesters know might be their only chance of finding a way to beat the Darkness as the former Scribe of God. However, searches for accidents or moving violations with Castiel's stolen car come up with nothing to Castiel's surprise as he didn't think Metatron would be a good driver. Sam eventually finds a possible clue to Rowena's location and he and Dean take off to check it out, returning with a captured Rowena who they make a deal with: break the spell on Castiel and they will let her go. While they are discussing that and the *Book of the Damned* with Rowena, Castiel continues the search for Metatron on Dean's computer by trying to search databases for his car using instructions left for him. However, he accidentally activates some porn and stares at it for a moment before closing it down. Castiel falls back under the influence of Rowena's spell, breaks free and stalks a girl through the nearby town. As he's strangling the girl in a warehouse, Dean interrupts and Castiel attacks him too, beating him a bit. Sam finally arrives with Rowena who breaks her spell and then escapes. In the Bunker, Castiel, now back to normal offers to heal Dean, but he refuses, feeling he deserved the beating and forgives Castiel for it. Castiel is upset as they had Rowena captive but she got away because of them saving him, but Sam tells him that they got back Nadia's Codex and Charlie's translations which will slow her down a bit. They'd also have lost the *Book of the Damned* for good if they'd killed her.

 File:Imageyes.gif
Castiel finds Dean in *The Devil is in the Details* and tells him to stay far away from the site where the angels attacked Amara. He goes there himself and meets a fellow angel. However, this angel gets consumed by Amara who is proven to be okay. Castiel was shocked to meet his aunt who easily overpowers him but spares him. Amara carves a message onto Castiel's chest and sends him away.

Castiel later follows Dean into Hell to stop Lucifer from hurting Sam. Before Rowena can send Lucifer back into the Cage, Castiel asks the archangel if he can truly beat the Darkness. When Lucifer confirms this, Castiel says "yes" and his vessel is promptly possessed by Lucifer.

In *The Vessel*, as Lucifer feeds on Sam's soul and prepares to kill him, Castiel fights back and manages to regain control over his body. Castiel tells Sam the truth and that he can't cast Lucifer out as he's using all of his strength just to keep the archangel from killing Sam. He also informs Sam that he can no longer time travel, so they need Lucifer to save Dean. After Lucifer rescues Dean, Dean learns the truth as well before Sam banishes him. The two agree to try to save Castiel from Lucifer, but know that he may not come back willingly since he said "yes" to Lucifer on his own.

In *Hell's Angel*, Dean and Sam – with the help of Rowena and Crowley – trap Lucifer inside a ring of holy fire and activate an angel suppressing sigil, so they can talk to Castiel and convince him to expel the archangel. Castiel briefly awakens and notices Dean, but before they can talk properly, Lucifer regains control and pushes the angel back down.

Crowley thus decides to enter Castiel's vessel and talk to him directly. Crowley discovers Castiel's safe place to be the bunker's kitchen, where Castiel is watching television. Crowley notices that Castiel has lost interest in the war and doesn't seem to mind Lucifer's presence, saying he mostly just leaves him alone.

 File:Cas with TV.PNG
Castiel has a jolt of memory that he saw Dean earlier, but gets distracted by the show he's watching. Lucifer arrives shortly after and beats on Crowley. Castiel complains that the two might break something, referring to his television, which he protects. The three of them soon hear Sam chanting an exorcism spell. Once Crowley leaves, it is Lucifer who regains control.

In *We Happy Few*, Lucifer returns control to Castiel in an attempt to convince the angels to join the attack on the Darkness. The angels aren't inclined to listen to Castiel anymore than they are Lucifer, but Castiel tells them that his role in the battle is to be Lucifer's vessel despite the fact that it is burning him and his vessel out. Castiel insists that he would continue to do it anyway if given another choice and is able to convince the angels to join them.

 File:Castiel talking to the angels in We Happy Few.PNG
After the attack on Amara fails, Amara pulls Lucifer from Castiel's vessel, leaving Castiel unconscious on the ground. When Dean wakes him up, he finds that Lucifer is indeed gone, but Castiel is unaware as to where he is. Castiel is helped by the Winchesters and finally meets his creator God who he notices isn't doing to well as he was wounded by Amara.

The team regroup outside to find that the sun is dying. Unsure of how to deal with such a major situation, everyone – including Castiel – start to feel down and hopeless, except for Sam. When they try to get help from the angels and the demons again, Castiel discovers that the angels are planning to lock up Heaven and wait for an honorable death, as they know that God is dying.

 File:Spn1123 2103.jpg
Castiel joins Dean on a road trip and explains his reason for allowing Lucifer to possess him. He admits the idea was stupid, but Dean doesn't fully agree. Dean reminds Castiel that he is a brother and best friend to him. Suddenly, the two receive a call from Sam about a plan, which involves creating a soul bomb.

The reaper Billie helps in gathering the souls while Rowena plants it inside Dean, so he can use it to kill Amara. Dean bids everyone a farewell, and hugs Castiel goodbye. Castiel joins God, Sam, Rowena and Crowley at an empty bar. God soon joins Dean and Amara. After a while, the group at the bar discover that the sun has been restored, and deem that Dean's mission was a success.

Castiel and Sam head back to the Bunker, where they are greeted by a mysterious woman who banishes Castiel and confronts Sam about his past actions.

### Season 12

In *Keep Calm and Carry On*, after being hit by Lady Toni Bevell's angel banishing sigil, Castiel is blasted through a billboard into a field three hours away from Lebanon. Castiel questions a passing driver on his location then stuns the man in order to steal his truck and return to the Bunker.

 File:SPN 0680.jpg
At the Bunker, Castiel calls out for Sam only to be confronted at gunpoint by a resurrected Mary Winchester. After a brief standoff, Mary is calmed down by Dean who Castiel is shocked to see alive and hugs. Dean introduces Castiel and Mary who are shocked by who Mary is and the fact that Castiel is an angel respectively. Castiel tells Dean and Mary of the events before he was banished and Dean hacks into the traffic camera footage nearby, using the time Castiel gives him to locate the kidnapper's vehicle.

At the airport, the group locates the vehicle and questions the man who owns it. When he refuses to talk, Castiel attacks him and eventually intimidates the man into giving them the tail number of the plane Toni arrived on. As Dean searches for information on the plane, Castiel listens to Mary about how strange she finds everything including and since her resurrection. Dean returns and tells them that he has learned that the plane has a diplomatic registry, meaning that they can't access its flight plan. Castiel notices a nearby veterinary clinic and realizes that Sam could've been treated for his injuries there. Kidnapping the doctor, the three question him with Castiel getting violent once more when the man refuses to talk. Eventually, the doctor tells them that he was paid $100,000 to treat Sam's leg wound with no questions asked. When it seems he is holding something back, Mary orders Castiel to beat the information out of the man. Finally, the man tells them that he has Toni's phone number as she had called him to ask about the sedative he'd used on Sam. Castiel stands with Mary and watches as Dean calls Toni who refuses to give up Sam.

Driving back to the Bunker, Dean tells Castiel and Mary that they have Toni's phone number and can try to track her phone with it. At that moment, Ms. Watt rams the Impala with an SUV, knocking out Mary. Dean leaves Castiel to watch over Mary while he faces Ms. Watt who arms herself with enchanted brass knuckles that gives her the edge in the fight. Castiel joins in, but the brass knuckles are able to harm even him and he loses his angel blade. Dean and Castiel lose the fight, but before Ms. Watt can kill Dean, Mary kills her from behind with Castiel's angel blade.

Following Ms. Watt's death, Dean and Castiel push her SUV off the road and Dean is able to track the last call on her phone to Aldrich, Missouri. The three depart in the Impala to track down the lead and hopefully Sam.

In *Mamma Mia*, Castiel, still driving the truck he stole from the man he met after his banishment, searches Aldrich, Missouri for any sign of Sam but is unable to find any signs of him in the abandoned buildings in town. At Dean's suggestion, Castiel begins searching for places rented legitimately given the resources Sam's kidnappers seem to have access to. Castiel is able to locate a farmhouse rented by a woman with a British accent and powerfully warded. Castiel alerts Dean who arrives to check it out with Mary tagging along. Unable to enter due to the warding, Castiel reluctantly stays outside with Mary who eventually enters on her own. After Sam is rescued from Toni, Castiel appears in the farmhouse with Mick who had lowered the wards so that Castiel could enter as a sign of good faith. Mick explains what the British Men of Letters had really wanted and that Toni had gone too far. While the Winchesters are dubious of Mick's intentions, Mick points out that he came in unarmed and lowered the wards for Castiel who could easily kill him. Mick and Toni then depart and the Winchesters return to the bunker with Castiel presumably healing Sam's injuries beforehand.

In *The Foundry*, Castiel discovers where Lucifer might be, and believing he is responsible for bringing the archangel back into the world, he chooses to hunt for Lucifer alone. Under the alias "Agent Beyonce", Castiel goes to speak with the bandmate of Lucifer's vessel, Tommy, and tells the man to call him if he sees anything. Soon after, Castiel runs into Crowley who asks to join him on the hunt, and Castiel agrees reluctantly, since Crowley knows the location of Wendy Vincente, the sister of Lucifer's vessel.

 File:Rowena agrees to help them trap Lucifer (12x03).PNG
The two go to visit Wendy and realize she has been healed by Lucifer, who recently paid her a visit. Wendy admits something was off about her brother, and that he had a red-haired company. Castiel is disturbed by the mention of Rowena, though he initially assumes Crowley's true intentions is to save her. Crowley denies it, and tells the angel that Rowena is likely to surrender her services to Lucifer, which will be a major problem.

The two trace Rowena and Lucifer to a cabin in the woods, but once they get there, they find Rowena alone sipping tea, since she had successfully managed to banish Lucifer elsewhere. The three proceed to leave the cabin, with Rowena promising to help them seal Lucifer away should they succeed in cornering him.

 File:First Blood 012.png
In *First Blood*, he searches for the brothers as he is met by Mary who reprimands him for losing her sons. Eventually, he calls Mick Davies and Arthur Ketch for help before Mary calls him again and he meets with her. She apologizes for her temper as he apologizes since he shouldn't have left and explains he has called for help. They meet the Men of Letters who find the boys' location and they follow them. After locating them, they drive off but meet Billie who reveals the deal with her and the boys. When Mary offers herself in their stead, Castiel snuck behind Billie and stabbed her with an angel blade. He explained to them tells him the world needs every last Winchester, and he won't let any of them die, that they meant too much to him, and he will face the consequences for their deal. His actions left the family in awe at his care for them.

During *Lily Sunder Has Some Regrets*, Castiel is reunited with his old garrison after he learns that someone is killing angels from the unit. Despite his intent to go alone, he is accompanied by the brothers who want to ensure he doesn't do another reckless act. Later on, he meets with Ishim and Miriam where he is met with distrust because of his past acts but he is allowed to speak with them. They soon fight the angel killer Lily Sunder, the mother of the supposed "Nephilim" who easily kills Miriam and wounds Ishim.

Castiel heals Ishim before he is drained by it and is met by Dean who tells him that May was really human and Ishim lied to him. Shocked, Castiel questions Ishim whose reaction to Dean's accusations confirms it. Ishim attacked them and grabs the weakened Castiel, hissing that he used to envy him for being chosen by God, but now he's sad, pathetic, and weak. Then he proposes to cure Castiel of his human weakness by cutting it out. After Dean tried to counter by drawing an angel-banishing sigil in blood, but Ishim pointed out that this will blast all the angels in the room, and Castiel might not survive in his weakened state. Dean's hand immediately drops.

 File:Castiel kills Ishim 1.PNG
Castiel watched as Sam brought Lily to fight Ishim before regaining some of his strength. Just as Ishim tried to kill Lily, Castiel snuck up on him and stabbed him from behind.

 File:Lily Sunder Has Some Regrets 06.jpg
With Ishim dead, the Winchesters broadly hint that Lily needs to retire her revenge agenda.

Castiel stops them and apologizes to Lily for her daughter and says that he may not have known they were killing an innocent, but ignorance is no excuse and can't imagine her pain. He tells her if she cannot leave and still can't forgive him, he'll be waiting for her revenge. Instead, Lily simply thanks him for killing Ishim and leaves the area.

In *Stuck in the Middle (With You)*, Castiel joins Sam and Dean on a hunt arranged by Mary. The plan is to locate and kill a powerful demon that is loose upon the Earth. When the group - which includes a hunter named Wally - arrive at the demon's house, the five are ambushed by demons. Wally is killed, while Sam and Dean manage to kill two of the demons. The main demon, Ramiel, stabs Castiel with a special lance, leaving Castiel mortally wounded.

Mary knocks the demon out by running into him with her jeep, then takes the group and runs to a barn. Castiel is unable to heal from the injury begins to slowly die. Crowley arrives and tells them the demon's name, while the Winchesters are unfamiliar with it Castiel reveals that the latter is one of Princes of Hell. Castiel reveals they were demonic generals for Lucifer but were believed dead though Crowley states that he had the demons spread the rumor so the princes can live in peace.

When Ramiel reaches their location, he throws Crowley the wall and fights the three Winchesters are able to defeat him by stabbing him with his own lance. The demon's death does not save Castiel, and seeing that he is about to die, Castiel professes his love towards all three of them. He orders the three to leave, but before anyone can move, Crowley wakes up and breaks the lance, having realized that doing so would save Castiel.

Castiel instantly recovers, and the brothers gladly take him back home.

In *Somewhere Between Heaven and Hell*, Castiel gets a lead on Kelly but he is sidetracked by an angel named Kelvin, who wants to take Castiel back to Heaven to talk with their siblings. Castiel reluctantly goes, being more eager to meet with Heaven's new commander Joshua, than actually going.

In *The Future*, Castiel returns from Heaven and is met with an angry Dean Winchester. Feeling his absence has betrayed Dean's trust in him, Castiel returns a mixtape Dean had made from him, but is told to take it back since it is a gift. While Dean isn't looking, Castiel snatches The Colt from under Dean's pillow and meets with Kelvin and Hozai outside Dagon's new hideout. While Kelvin compliments Castiel on choosing Heaven over the Winchesters, Castiel corrects Kelvin by telling that he is only doing this so Sam and Dean don't have to spill innocent blood.

The three infiltrate the house. Kelvin and Hozai try and fight off Dagon while Castiel confronts Kelly in the basement. Although his order was to kill Kelly then and there, he sneaks out with her in tow. Castiel drives Kelly to a motel when his truck breaks down. Castiel believes he failed a mission by sparing Kelly, but Kelly insists her son is good. She even encourages Castiel to touch her belly and feel the baby kicking. The sensation puts a smile on Castiel's face.

When Sam and Dean reach their location, the brothers demand to take both Castiel and Kelly back to the bunker and not the Heavenly Portal, through which Kelly and her son will be killed. Although Castiel submits to this decision, Kelly doesn't and drives The Impala to the Portal, taking Castiel with her. Upon arrival, Joshua greets them and asks Kelly to enter the Portal, but any attempt to do so is interrupted by Dagon, who kills Joshua and fights Castiel, as well as Sam and Dean, when the latter arrive.

 File:Dagon's Death.gif
An injured Castiel stands by Kelly while Sam and Dean get knocked aside. When Dagon returns to finish off Castiel, Kelly takes Castiel's hand causing her son to empower the angel and grant Castiel the strength to defeat Dagon. Castiel tells a surprised Dagon its a miracle before he incinerates her to ash. Sam and Dean are bewildered. Castiel, having been granted a positive vision of the future by the baby, decides to protect the baby in Dagon's stead. He knocks Sam and Dean out and takes Kelly away.

Soon after, Castiel relocates Kelly to a cabin by the lake, and begins purchasing supplies for her in preparation for the baby's birth. Castiel works diligently to the point that he even reads instructions on how to deliver a child. After purchasing a truckload of diapers and delivering it to the cabin, Kelly begins experiencing stomach pains and is forced to stay in bed.

 File:All Along the Watchtower 01.jpg
While Kelly is in bed, she asks Castiel about the vision he saw when the Nephilim lent him power. Castiel responds that he saw the future – a paradise without fear or hate that her child will help to create.

 File:All Along the Watchtower 004.png
Castiel exits the cabin and discovers a rift that leads to another reality. Castiel enters it and finds himself in a war-torn wasteland. He is suddenly attacked by a Tempter Demon, but is rescued by a familiar face. Castiel learns much about this world from the other person before he returns to Kelly in his own world. There, he is confronted by Sam, Dean and Mary.

Castiel gets into a brief argument with Dean who he heals as the latter tells them Lucifer is coming. Castiel tries to stop the brothers but they discover the rift to the alternate reality. Castiel deduces that the portal was created by the Nephilim's powers. The trio enter the portal and arrive in the other world, Castiel tells them of the world's history and tells them a friend there told him. Sam and Dean learn that Castiel's new friend is the other world's Bobby Singer. The trio soon confront Lucifer outside the cabin. Castiel charges forward, intent on keeping Lucifer away from his unborn child, but is easily flung aside. While he lay seemingly unconscious, Sam and Dean work with Crowley in sealing the rift, hoping to imprison Lucifer inside.

Castiel recovers shortly after and enters the rift. Crowley had just committed suicide to complete the spell meant to seal the rift. Ignoring Dean's protests, Castiel charges at Lucifer again and stabs him with an angel blade.

 File:All Along the Watchtower 010.gif
Sam and Dean quickly escape back into their own world, as Castiel returns to their relief only to be met with horror as Lucifer followed him and stabbed Castiel right before their very eyes. The angel collapses dead on the ground, his wings imprinted on the sandy ground. Lucifer is defeated moments after when Mary attacks Lucifer, sending them both tumbling into the rift right before it finally closes.

Sam goes into the cabin to check on Kelly who had gone into labor during the conflict, leaving Dean to stand over Castiel's corpse.

### Season 13

In *Lost & Found*, Dean briefly stands over Castiel's corpse, grieving, before heading inside the cabin. Castiel's body is later found laid out on the kitchen table and covered with a sheet by two angels. While the male angel - Conrad - believes Castiel deserved what he got, the female angel - Lily - thinks he deserved better.

After praying to God to bring back everyone they have lost fails, Dean and Sam decide to hold a Hunter's Funeral for Castiel. Alongside Jack, who sees Castiel as his father instead of Lucifer, the Winchesters burn Castiel and Kelly Kline's bodies outside the cabin.

 File:The Empty 1303.gif
In *Patience*, Dean argues with Sam about how trusting Jack cost Castiel his life. Overhearing their argument, Jack's eyes glow as he calls out to Castiel. In a black realm, the essence of Castiel is sleeping before he awakens, after hearing Jack's voice calling his name. Castiel is left confused at where he is.

In *The Big Empty*, he wanders through the realm of nothingness asking for someone to appear but gets no answer as he is followed by a mysterious being. Castiel soon senses the being's presence and calls out to it, the being is the The Shadow who takes on his form to communicate and so he wouldn't be afraid of its true form. Castiel then learned the details of the realm, which is called The Empty that has existed long before everything including God and The Darkness, and it is where angels and demons are sent after death before being put in eternal slumber. The entity remarks that Castiel was awake, as it states that nothing ever awakes there but Castiel is awake for a reason and has awoken the entity because of it. The entity questions Castiel who didn't know suggesting the Winchesters had a role in it but the entity rebuffs this, as it only had power in the realm and decides to probe through his memories in an attempt to find out what could've woken up Castiel as he is put in intense pain.

 File:Castiel 1304.png
Afterwards, the shadow explained to Castiel, who remains in pain, what he did and that he wants Castiel to go back to sleep. Castiel realizes from the entity's description that having Castiel awake is painful for him which the entity confirms, stating that if Castiel can't sleep, it can't sleep. The entity insists that it likes and needs sleep, causing Castiel to suggest that it get rid of him by sending Castiel back to Earth. The entity suggests that it instead throw Castiel so deep into the Empty that he can't bother it anymore, but Castiel recognizes that the entity is bluffing and that it won't work as the entity would've already done it if it would work.

The entity acknowledges that Castiel is right, but refuses to send him back, telling Castiel that "its not part of the deal" and how he doesn't want to return. Castiel stated his friends needed him but The entity states that it has gone through all of Castiel's mind and knows everything there is to know about him and claims that there is nothing back on Earth for Castiel. The entity grasps Castiel's head and painfully shows Castiel visions of his grace being stolen by Metatron, his death at the hands of Lucifer, the Escape of the Leviathans and Castiel returning the souls to Purgatory. The entity then beats Castiel, attempting to convince Castiel he's worthless so he would return to sleep. However, Castiel refuses the entity's demands and declares that since he is awake that no matter what the entity does, he will keep it awake and fight it for eternity if he is not released. The Shadow angrily denies Castiel's words, as Castiel boldly continues to demand his release from the realm and stares down the entity.

Castiel later awoke in a meadow on Earth and realized that The Shadow, has complied and resurrected him, just as he demanded. Castiel then basks in the sunlight, happy to have been brought back to life.

 File:Destiel Reunion 1305.gif
In *Advanced Thanatology*, Castiel traveled to a small town where he uses a pay phone to contact Dean who is shocked to hear him. The Winchesters travel to the area and are surprised to see Castiel alive again as he greets them with a nod.

 File:Tombstone 09.jpg
In *Tombstone*, Dean and Sam are still shocked at seeing Castiel alive again as he confirms its really him and explains he annoyed an ancient cosmic being so much that it sent him back. With that, he is embraced by the brothers who questioned if he was in Heaven but Castiel replies that he was in The Empty and tells the surprised brothers that his experience there was horrible as it was like travelling through an endless void of nothing. He explains he was awoke from his slumber after hearing a voice say his name, as he states his belief that the brothers had something to do with but they reply it wasn't them as they believed it was impossible. He is then is asked if God had something to do with it but Castiel replies God doesn't have control there as the brothers soon realized that Jack had a role in it and go off to tell him about it. Castiel returns to the Bunker with them and finally meets Jack who is shocked to see him alive and Castiel thanks him for his part in bringing him back. In response, Jack hugs Castiel, extremely happy to finally meet him and shows what he has learned from his time with the Winchesters.

 File:Tombstone 02.jpg
While working on an assignment, Jack and Castiel catch up with Castiel apologizing for not being there when he needed him but the latter assured him it was alright as he understood it wasn't by choice. When Jack gets a lead, he goes to tell Dean though Castiel warns him but Jack learns the hard way as Dean points a gun at him. The group split up with Castiel going with Dean while Sam goes with Jack for other evidence, Dean makes Castiel wear a cowboy hat as they get information about the monster from the police.

They meet up with Jack and Sam who met the mortician Athena Lopez but they don't believe her to be a potential monster as it makes little sense. The group then learn of the truck found at the murder being stolen and review the footage of it before the murder. Dean recognizes the driver as an outlaw from the 1800s. They realize that Jack was right about it being a hunter's case but the monster was a Ghoul, which Castiel explain to Jack who soon recognizes him and reveals the ghoul as the mortician's boyfriend.

After tracking the Ghoul to a bank, a gunfight breaks out. In an attempt to stop it, Jack ignores Castiel's pleas and unleashes a telekinetic blast that throws the Ghoul and a security guard back. The security guard hits his head on a pole and dies with Castiel being unable to heal him as Jack breaks down. As Jack seems to be struggling with the fact he has killed someone, Dean has Castiel and Sam take him back to the bunker as he deals with the ghoul.
Once there, Sam and Castiel attempt to console him and tell him that he just made a mistake Jack seems to be taking it harder than the others realize. When Dean returns, he explains he had the ghoul take the fall of the guard's death as Jack has an outburst regarding the dead man and is scared that he will hurt the others saying the they are all he has and he can't hurt them. Jack throws them back saying he is sorry and teleports out of the bunker.

In *War of the Worlds*, Castiel searches for Jack and makes contact with angels for help and tells the brothers he'll handle it alone. Going to a park, Castiel meets with the angels who want him to help find Jack and use his power in order to rebuild their race which was depleting after Metatron's actions. Things turn hostile, as Castiel engages them in battle and is nearly taken down but the three angels are stopped by Lucifer's return to the main reality as he orders them to release Castiel, threatening them as he does. The three angels release Castiel and flee as Lucifer collapses on a bench out of energy in his weakened state.

Castiel was shocked and angered to see his brother again, nearly killing him for revenge for his previous deaths but Lucifer warned him of the potential danger of it as they talk for a while explaining how they are both back after their previous encounter before Lucifer tells him of an impending threat.

Following this, Castiel and Lucifer go to a bar where Castiel reluctantly sits with Lucifer to talk about Jack despite their differences, apologizing sarcastically for stabbing Lucifer the last time they met. Castiel briefly talks with Dean before his phone is taken by Lucifer who doesn't want the Winchesters involved. They can continue talking with Castiel appearing to be willing to put aside his differences with Lucifer for Jack's sake and due to the threat of the alternate Michael however, Asmodeus arrives and captures them after subduing them. With him imprisoned, Asmodeus steals Castiel's phone pretending to be him after Dean calls and he tells he is alright. Asmodeus places Castiel in a cell to use as a bargaining chip while Lucifer is put in an adjacent cell for potential in the conflict with the invading Michael.

In *The Bad Place*, Castiel is mentioned by Jack to being one of the few people besides the Winchesters that Jack sees as his true family.

 File:Various & Sundry Villains 09.jpg
During *Various & Sundry Villains*, Castiel remained in his cell trapped with Lucifer and was promised torture by a guard demon. As he bemoaned his time, he talked with Lucifer who asked for some of his grace to break out but he refused and doubted his claims about Michael. However, Lucifer states he wouldn't lie about that comparing the other Michael to their own Michael in which they will stop at nothing after setting their minds to something. Castiel then asks how much time they had with Lucifer mentioning very little while even bringing up the torture the latter administered on Mary Winchester. Castiel was horrified to hear this as Lucifer taunted him but he retaliated by describing Jack's ways which were opposition to his father who he detests. His taunts cause a furious Lucifer to bring out some of his powers. Lucifer soon frees Castiel and they keep up the act of insulting each other as the same guard demon Dipper returns. When the latter agrees with one of Castiel's taunts, Lucifer overpowers him and manages to wound him as Castiel smites him. The two proceed to leave their cells before they are confronted by more guard demons but they manage to kill them and escape the area. Outside, Lucifer rests as Castiel warns him of the threat and Lucifer hints that he would be more of a help if Castiel would lend him some of his grace but the latter refuses even stating he won't make the same mistake. Lucifer gets angry and attacked him to take some of his grace but in his weak state, Castiel is able to stab him as he states he is making up for his previous mistake.

In *Devil's Bargain*, Lucifer escaped Castiel and the latter searched for him before collapsing in the woods. He was found by a small boy who mistook him for a corpse who he showed to a friend before they poked him and he woke up scaring off the boys as he wondered of his surroundings. Castiel returned to the bunker and spoke with Sam and Dean who he tells of his imprisonment by Asmodeus for weeks. He reveals it was Asmodeus mimicking him and using his phone to monitor them. When asked why he was captured, Castiel states it was because of the latter wanting Lucifer who he reveals to the surprised brothers has returned from the alternate reality.

The brothers ask how he could have came back, as Castiel reveals it was due to the other world's Kevin Tran using a spell to allow it. Castiel confirms they have an angel tablet which that world's Michael intends to use so he could invade their world, a statement that leaves the brothers shocked. He confirms his beliefs by mentioning Lucifer was afraid of Michael and wanted to help though brings up the latter's attempt to kill him after they escaped.

The brothers move to make a plan before asking about Mary and Castiel reveals she's alive but knows very little of her wellbeing. They bring in Donatello Redfield and plan to have him read a spell on an angel tablet that could open a rift to the other world so they could locate their mother and Jack before Michael harms them. They decide to search for and capture Lucifer who is in a weakened state.

Castiel and the Winchesters traveled to Missouri, where they meet a beggar who met Lucifer and he tells them where he went. At night, the Winchesters and Castiel go to Sister Jo's building but find Arthur Ketch instead and he says he was tracking Lucifer but proposes a team-up. Distrustful, Castiel knocks him out and they stuff him in the impala's trunk to question him and kill him.

The Winchesters soon track Jo's card to the motel and meet her where Castiel reveals she is an angel and she leads them to Lucifer. A confrontation breaks out, as Dean tries to capture him but Anael helps the archangel who overpowers them and proceeds to torture them but Arthur Ketch arrives and throws a demon bomb but Lucifer whisks himself and Anael away.

 File:Devil's Bargain 09.jpg
The group question Ketch on his help as he explains he has to draw the line somewhere and again offer to help them. He reveals he is working for Asmodeus and can as a double agent for the Winchesters since he knew of Lucifer and the invading Michael's threat.

At the bunker, Castiel asks if they can really trust Ketch but the Winchesters assure him that they would kill the man should try anything.

During *Good Intentions*, Castiel apologizes in advance as he painfully strips the spell from Donatello's mind. Afterwards he leaves the room, he tells the brothers he did what needed to be done as they tend to the prophet. When the brothers return from the hospital, they angrily tell Castiel Donatello is alive but brain dead and hooked to machines now. Castiel justifies his drastic action by revealing Donatello was working for Asmodeus though unwillingly. He tells them what they need to open the rift to the other world.

In *A Most Holy Man*, Castiel is mentioned to have gone to Syria to procure the Fruit from the Tree of Life.

 File:ScoobyNatural 25.jpg
In *Scoobynatural*, he returns to the bunker where he searches for his friends to tell them of his success but mentions he thinks he may have married a Djinn queen after bartering with her and killing some followers. Castiel finds no sign of the brothers but hears a television and sees to his disbelief that they were sucked inside. At a loss of words, Castiel sees purple lightning before he is sucked into the TV as well.

Castiel finds the brothers as they traveled with the Scooby gang and follows them. He then meets the Scooby gang and is confused by how their dog can talk which he points out to the brothers. The group splits up to investigate with Shaggy and Scooby, to his annoyance. After they find the ghost, Castiel notices something off before running with his group.

They all meet up, and the Phantom attacks them, with Fred getting injured, and Shaggy getting thrown out through the balcony door. Sam and Dean drive off the Phantom, using iron candlesticks and find Shaggy holding on for his life. Scooby jumps to save Shaggy and Castiel jumps and slows their descent to the ground, but Shaggy's arm gets broken. With Shaggy's injury and the unexplainable abilities displayed by the Phantom, the Scooby Gang is confused by the unusual circumstances. Castiel, Dean, and Sam decide to tell them that all the paranormal stuff is real, including the ghost. Castiel is shocked as the Scooby Gang begins to have a nervous break down by this revelation, but Dean stops them by mentioning their past acts to encourage them, which gets Sam to reveal he watched the show as well.

Before they leave, the three find the Scooby Gang suffering a second nervous break down which Dean states they can't leave them in. To set their minds at ease, they have the ghost disguise itself as Cosgood Creeps in the Phantom costume, making the cartoon heroes believe the whole thing was just another staged set up by a normal human. Castiel secretly healed Shaggy's broken arm, making the latter think it wasn't injured at all. Castiel then hugs Scooby and Shaggy, praising their brave acts in saving each others life. Castiel also jokingly mention about "Danger", which promptly make Shaggy and Scooby running.

The child returns Castiel and the Winchesters to the real world, and they destroy the knife in the television, putting the kid to rest. Afterwards, they go back to the pawn shop, finding Alan about to sign his store over to Jay, and confront the Real Estate Developer of his crimes, knowing he used the ghost to drive off owners to buy their property and then on Sam and Dean when they got to close to discover his plan. While they knew he would never be arrested for those actions, they hacked his finances and had him arrested for tax evasion.

As Jay is arrested, he uses the meddling kids quote from Scooby Doo and Dean uses Scooby's phrase but Sam and Cass tell him to cut it out.

 File:Bring 'em Back Alive 06.jpeg
During *Bring 'em Back Alive*, Castiel returns to the bunker and is shocked Dean went to Apocalypse World alone and is not all moved to hear Arthur Ketch is with him. Castiel then sees his brother Gabriel and remarks to Sam that he didn't tell him that he was in a worse state than he described. Castiel tends to him but Gabriel's condition remains the same as they tend to him but wonder if he'll truly be alright after he refuses his own grace. They also wonder how he is still alive before Castiel suggest he might be too gone.

The two leave and Castiel returns to see Enochian Language on the wall, he alerts Sam of this. Castiel translates the writing and it tells him and Sam how Gabriel faked his death by creating a duplicate which Lucifer stabbed into. Gabriel then went into hiding and lived a life freed of being tethered to Heaven and humans before he was kidnapped by Asmodeus who would steal his grace to grow stronger. From this, they see Gabriel's mind is still intact but he may not trust them to fully communicate. Castiel tries to fix his thoughts states he is unable to actually heal Gabriel and believes they just have to wait on him.

Eventually, Gabriel speaks to Sam as he slowly regains his powers. Castiel and Sam are relieved that he is back to normal and give him some of his grace. However, Asmodeus (who detected Gabriel's power) calls Sam and tells him to hand over Gabriel or he'll come to them and destroy the bunker.

Knowing the severity of the threat, Castiel and Sam try to ward off the bunker from the Prince of Hell but it was for nothing as Asmodeus and his forces invade. Castiel kills several demons including one that tried to kill Sam before they were knocked away by Asmodeus who states the warding couldn't stop him. As demons take Gabriel away, Asmodeus begins to inflict pain on Castiel and Sam. Seeing this, Gabriel breaks free of his captors and heals himself, he kills Asmodeus by incinerating the demon, saving his friends.

Afterwards, Castiel and Sam caught Gabriel up on everything that has transpired by, such as an alternate universe Michael trying to invade their world, Jack being sent to the Apocalypse World and they asked him to help them but he declines and tells them that he will put his faith in them. Castiel begs his brother to not walk out on their father's work but he again declines, as he wanted no part in the conflict and he left the bunker.

When Dean returns, he is informed of the events that occurred but was angry at the latter's refusal to help. Castiel swore to Dean that they'd find Gabriel again.

In *Funeralia*, Castiel and the Winchesters try to track down Gabriel but have no luck. They contact Rowena who ignores their pleas and Sam complains about this before going over his computer. Castiel decides to go to Heaven for help before he reveals news about killing people who had heinous pasts.

Castiel arrives at the Heavenly Portal, finding it unguarded before he finds the guard Indra trying to get drunk. The guard tells Castiel cryptic description about Heaven's state and lets him pass. Castiel goes to Heaven where he meets Duma and two other angel, he tells them he needs the angels' help in finding the archangel Gabriel who he reveals is still alive. He also explains that he needs them in fighting an Alternate Michael who wants to invade and conquer their world. Though wary, Duma hears Castiel out and decides that maybe they can help each other after all and leaves Castiel sitting in Heaven's Throne Room for a long time. Finally, Duma returns, asking about Gabriel and getting him to Heaven. When Castiel admits that he doesn't know where Gabriel is and asks Duma to send a few angels to search for him, Naomi arrives and explains that Duma can't. Seeing Naomi, Castiel becomes surprised and angry before he questions her survival as she reveals that the drill couldn't kill her. She takes Castiel to her old office to speak with him, leaving Duma and the other angels behind.

In her office, Castiel admits that he was relieved when he'd believed Naomi to be dead, causing Naomi to comment that they never did see eye to eye. Castiel angrily confronts Naomi over her actions such as stealing his memories, threatening to tear him apart, making him repeatedly act out Dean's murder and killing many, many people in front of him. Naomi simply states that "those were simpler times" and explains that after Metatron attacked, she had a few reliable angels spread the word that she was dead.

Castiel notices Heaven's power flickers, as Naomi asks him if he knows what powers Heaven. After he tells her that its angels, Naomi explains that every angel is like "a walking, talking battery." Gesturing to the power flickers, Naomi explains that its what happens when they run out of power. Castiel is then told that there are a grand total of nine angels in Heaven, including the two of them and one or two on Earth "and that's all. We are the last men and women and divine waves of light standing, as it were." Castiel is horrified by the news, having known that their numbers were small, but not that small.

 File:SPN 1517.jpg
Naomi tells Castiel that they can't help him because no angel can leave Heaven, they are the only thing still keeping the lights on "barely." They need more, especially an archangel. Naomi states that the others thought that any archangel would do and dismisses it as "a long story," but Castiel's news about Gabriel is blessed as with his power, the angels can keep Heaven running. Without Gabriel, the angels will burn out in time, Heaven will crumble and all of the souls in Heaven will fall back to Earth. This would mean billions upon billions of ghosts unleashed upon the world with massive chaos and death.

Castiel returns to Earth, as Naomi accompanies him through the Heavenly Portal. Naomi asks that if Castiel finds Gabriel to let him know about what is happening in Heaven. Naomi promises that if Castiel can't, the angels will do their duty and keep things running for as long as they can. Though Castiel promises that they will find a way to fix the problem, Naomi appears resigned to their fate, suggesting that what is happening is one of the things that simply can't be fixed and "everything ends." Naomi tells Castiel that until the situation is resolved, the Gates of Heaven are closed. After sharing a nod with his sister, Castiel watches Naomi depart through the portal which seals behind her.

During *Unfinished Business*, Castiel is mentioned by Dean to be searching for Gabriel in Texas. He is later mentioned to be helping Gabriel (who decided to join) in settling in the bunker.

In *Beat the Devil*, Castiel and the others prepare the spell for the ritual as he tells everyone Gabriel is extracting his grace in Dean's room. However, it wasn't enough grace to open the rift and this caused the others to reconvene about the plan. Castiel suggested tracking down Lucifer as he is the only choice, Dean and Sam were against this since they had too much experience with him. Castiel convinces them they have no choice since Lucifer was always their responsibility since he was let out of the cage.

Agreeing Sam tells Castiel and Dean he has plan, they go to notify Rowena and Gabriel who just finish having sex of Sam's plan.

After Rowena and Gabriel capture Lucifer, Castiel personally cuts his brother's throat for his grace to power the rift. Once the rift opens, Castiel and the others leave Lucifer with Rowena as they head to the other universe.

In Apocalypse World, Castiel talked to Gabriel and told him of Heaven's state and how it may need him to maintain its state. Gabriel is reluctant since he once abandoned it as Castiel reassures him. The group come across humans who they save from a vampire, Castiel learns that since the angels have exterminated most of humanity, the monsters are getting hungry and wilder for humans to devour. They are then told that Jack and Mary are at a camp which is where they are headed and there is a shortcut but vampires are there, Gabriel wanted to avoid it but Sam and Castiel tells him it is the best way.

Traveling through a tunnel, they deal with swarms of vampires which they fight off. Unfortunately, Sam was attacked by vampires and was dragged off by the vampires screaming. Castiel went after him and killed the vampires but was horrified to find Sam dead and told Dean not to look to look at the carnage.

Very soon, they find an area with warding that weakens Castiel before Gabriel cancels it out and they find Mary who Castiel is happy to see as she is surprised to see him. Mary takes them to the camp and Castiel reunites with Jack. When Jack becomes distraught at Sam's fate, Castiel tries to comfort him but the latter turns him away and asks why they didn't revive him. Both Castiel and Gabriel tell their nephew that they aren't strong enough to resurrect Sam. However, a surprising sight arrives it is Sam alive but with Lucifer whose presence shocks Castiel.

 File:Exodus 9.jpeg
During *Exodus*, Castiel is shocked to see Lucifer and pays witnesses to the tense moment between him and Dean which ends with Jack teleporting away. Lucifer volunteers to help them against Michael as they can't do so alone. Castiel then submits Lucifer to Supernatural Handcuffs if he is really willing to help and escorts his brother after Lucifer is punched by Mary. When Jack returns, Castiel becomes worried after the latter decides to talk with him and tries to discourage him but to no avail. Later on, Castiel tries again though he is forced to agree that Lucifer has point in not being able to spread evil while trapped in Lucifer's Cage.

 File:Exodus 12.jpeg
Castiel travels with the group, he is uneased with Lucifer with Jack and tells Sam that Gabriel went ahead. Gabriel appeared while being chased by a squad of angels, Castiel prepared for a fight but Lucifer easily killed them, revealing the cuffs had no effect.

Afterwards, Castiel takes part in the interrogation of a Resistance Traitor and at Dean's signal tortures him until the latter reveals he allowed the Alternate Charlie and Arthur Ketch to be captured.

During the attack on the angel camp, Castiel intercepts his fleeing counterpart and quickly overpowers him after pinning him to the vehicle with an angel blade to his throat. Castiel is not too shocked to see him as his fascinated counterpart is to see there was "more than one of us." Castiel is disgusted that his counterpart would align himself with Michael and hurt humans and tells him that he much prefers humans to angels. His double states that he isn't any better than him and they are the same. Agreeing with the sentiment, Castiel stabs his other self in the abdomen with his angel blade, killing him.

 File:Exodus 18.jpeg
Castiel takes part in the evacuation to the prime world, after he emerges through the rift he greets Rowena who remarks it was about time before Sam and Dean arrive as well after leaving Lucifer trapped.

During the celebration, Castiel was sad to hear that Gabriel was killed by Michael but was pleased his efforts weren't in vain. He asked about Lucifer and was told by Dean that Sam handled him.

In *Let the Good Times Roll*, Castiel goes on several hunting cases with the Winchesters and Jack before they receive shocking news. One of the humans Maggie was killed by an unknown assailant and Jack goes off to hunt down the possible killer.

Following Jack to a gas station, they stop him from hurting an innocent employee and he leaves shocked that he hurt someone again. As they worry, angel talk is heard and they see a figure watching them before rushing out after the windows are destroyed and the cause is revealed to be Michael who greets them. Shocked to finally meet the Alternate Michael, Castiel becomes angry after remembering Gabriel's death and quickly tries to attack in anger, despite knowing the power Michael wields but is stopped by Sam from fighting while Michael provokes him. Dean then ignites holy fire to keep the Archangel at bay as they retreat from the area.

They returned to the bunker and wondered how Michael made it to their world before they see Maggie alive as she was resurrected by Lucifer who also returned but took Jack.

The group started to plan before Michael arrived and Castiel engaged him but Michael effortlessly knocked out Castiel. Sam prayed to Jack for help and the latter arrived and severely wounded Michael. Castiel woke up and joined Dean and Sam in telling Jack that Lucifer allied with Michael to enter their world and criticized his brother for leaving them to be killed while he makes off with Jack.

Unlike Dean, Castiel was unwilling to let him possess Dean as he, somewhat correctly, believes that Michael would take full control over Dean. He watches as Dean states he has no choice since his family is in danger.

 File:Let the Good Times Roll 6.jpeg
Afterwards, Mary and Bobby return to the bunker where they find Castiel sitting down, bemoaning Dean's fate as the vessel for the corrupt Archangel. As Mary and Bobby approach him, Castiel simply shakes his head in despair, as he knows what had happened.

### Season 14

 File:Stranger in a Strange Land 13.jpg
In *Stranger in a Strange Land*, Castiel contacts the demon Kipling in an attempt to locate Dean. Meeting at Martha's Mowtown Meats, Castiel questioned Kipling who expressed surprise that Castiel wanted to meet with him and that Castiel was looking for Dean when Kipling believed them to be "joined at the everything." Kipling questioned Castiel on what would be in it for him if he answered Castiel's question and Castiel told him that Kipling would get to live if he did and if he didn't Castiel would burn him to ash. However, Kipling revealed he had anticipated this and had the other demons in the restaurant (who were patrons and staff) reveal themselves and they beat Castiel to a pulp. Restrained, Castiel watched as the demon called Sam using his phone to demand that Sam meet with him if Sam wished to see Castiel again alive. As they waited for Sam to arrive, Kipling offered Castiel a drink despite acknowledging that it had no effect on either of them due to their respective natures. Castiel watched as Kipling negotiated with Sam over being the Ruler of Hell before a fight broke out and ended with Sam killing Kipling and abolishing the title. Castiel was soon released and went home with everyone.

Later on, he apologizes to Sam for letting himself be captured but Sam relieves him of guilt as he may have did the same. Castiel soon goes into Jack's room while Jack is wallowing in self-pity of his own powerlessness and uselessness. Castiel reassures Jack that his grace would regenerate in time and that even if Jack doesn't have his powers, he still has his family, although it does not work as Jack is still frustrated by how without his powers, he cannot stop Michael.

 File:Gods and Monsters 07.jpg
In *Gods and Monsters*, when Jack goes over lore about his grace returning Castiel tells him it might take longer because of his human status being a factor. Jack is angry since Michael could cause serious damage in that time and he can't stop it.

While at the bunker, Castiel speaks to Nick who notices his nervousness around him. Even though Nick assures Castiel, he is still put off when remembering his brother. After Nick regains part of his memory and breaks down at Lucifer taking advantage of him, Castiel (recalling his own possession by Lucifer) relates to him and tells the man that is what Lucifer did to everyone. Soon, Castiel notices that Nick is still suffering from Lucifer's influence after he snaps his fingers at Castiel in a Lucifer-like manner after being enraged. Castiel examines Nick and determines that while Lucifer is gone, he may have done more damage to Nick's psyche than they realized. Castiel admits to sympathizing with Nick, explaining his own history with his vessel Jimmy Novak. However, Nick sees Castiel as no better than Lucifer for what he did to Jimmy, leading Castiel to tell Nick that what happened to Jimmy and his family is the biggest regret of his long life.

After Jack returns to the bunker, Castiel is irate at his reckless action though stops after Jack states he needed clarity. Jack soon asks about a way to stop Michael, Castiel tries to consider one while Jack states they might have to kill him, something that causes Castiel to argue with his statement as Dean would die too. However, Jack states Dean would rather die than suffer at the Archangel's hands.

 File:The Scar 8.jpg
During *The Scar*, Castiel and Jack are reunited with Dean who they are happy to see but question on what became of Michael and the latter's intentions. Dean responded he had no idea and went to rest, as Castiel confirmed to Jack it is Dean. Much later, Dean finds himself with a scar on his arm and has no memory of it along with his possession by Michael, Castiel accesses his memories to find out why Michael left Dean and what left a strange scar on Dean's left arm. This triggers a memory of Michael being stabbed in the arm by the hooded figure with their spear, Castiel questioned who the figure was. Castiel and The Winchesters contact Jody Mills who has been investigating three murders she thought were done by a human serial killer but realizes were done by the mysterious person when they describe the weapon. Castiel tries to go with the brothers but a girl who was cursed by a witch comes in and he has to tend to her.

Very soon, the girl who was cursed has succumbed and Castiel has to tell Jack of it. He watches Jack mourn her before he gets an idea, he examines the witches' corpse and deduces her spell is still in effect and spots the necklace she was wearing. He destroys it and the essence goes back to the girl who is resurrected and returned to normal. Castiel congratulates Jack and promises to put in a good word to Sam and Dean about going on a case, to Jack's joy. Castiel noticed Jack was seemingly sick and was told, he was having his first cold and he left thinking everything was alright.

 File:Unhuman Nature 01.jpg
During *Unhuman Nature*, Castiel tends to Jack and finds something is wrong with his body and after he collapses they take him to a hospital. Castiel learn Jack's body is shutting down as he becomes worried. The group contact Rowena and she agrees to help after Jack thanks for saving him. Once Rowena diagnoses Jack, they learn that grace needs to reconstruct his body cells and Castiel's won't do after he offers, as Rowena states only that of an Archangel will do. They contact Arthur Ketch who directs him to a Shaman the men of letters went to. The man was known by Sergei who Castiel decides to meet alone. As Castiel approached Sergei, the latter trapped him in holy fire. After learning that Castiel was alone, he released him. Sergei assured Castiel that his job is solving the unsolvable and gave him a spell and a vial of Archangel grace, which Castiel learns came from Gabriel who went to Sergei before hiding. Castiel asked what he wanted as the man requested for him to tell Sam and Dean that they owe him one.

Castiel returned with Sergei's spell and the grace as Rowena did the spell. It initially seemed to work but it is revealed to have only made Jack's condition even worse, Castiel called Sergei for help. The Shaman told Castiel it was just an experiment and Castiel threatened Sergei, that if Jack dies, he would find him. An unfazed Sergei responded with "you can try".

 File:Byzantium 05.jpg
In *Byzantium,* the group watch over a dying Jack and Castiel goes to talk with Dean but he can't move from his pain before Sam appears to tell them Jack died.

Castiel deduces Jack has ascended to Heaven, which he detects is having distress since its gates are opened. Castiel leaves for Heaven and finds it ransacked before locating Duma who tells him that something attacked her but she doesn't know what it was and she asks to accompany him since she is afraid, which he allows. They go into Jack's personal Heaven but he is not there and Naomi appears. She tells Castiel it is The Shadow, the entity that rules The Empty, something that makes Castiel remember his time in the realm. He questions how she knew and Naomi tells him that he is the only angel to escape the realm and states it is after Jack because of his heritage and Castiel becomes determine to protect him. Naomi tries to get him to reconsider but comes under attack by it and implores Castiel to run. Castiel knew Jack might be in the personal heaven of Kelly Kline and his theory was correct as Kelly is hiding him from the threat. Castiel lets them know its him and shares a greeting with them and Kelly relieves him of guilt after he states he failed her and tells him that Jack is wonderful before he explains that he and the Winchesters are working bring Jack back to life, which is why he present.

After he then informs them of how the procedure goes, they are worried until he tells them what is after Jack, telling them that because of Jack's angel heritage he will be sent to The Empty, which is why he should be revived. However, Duma appears but she is revealed to be possessed by the shadow, The Shadow mentions its meeting with Castiel who attacks it but is overpowered and knocked aside. While downed, Castiel receives word from Dean that the spell is finished as he watches Jack being defeated. The Shadow prepares to claim Jack but Castiel offers it a deal, his place for Jack. A worried Jack tries to intervene but Castiel convinces The Shadow as it makes the terms for claiming him at his most happiest as it wants to make his end painful, Castiel accepts before the shadow leaves Duma who regains her body.

Afterwards, Castiel tells Jack not to tell Sam or Dean of his act, as Jack states he will keep his secret to protect her son when he gets back and he promises. Castiel leaves Kelly's heaven before he is met by Naomi, who has recovered and thanks him for his act before giving him the location of Michael as a reward. Castiel is shocked to hear this and listens to her for the answer.

During *The Spear*, Castiel talks with Jack and the latter appreciates his selfless act. He later joins his friends on where to find Michael and defeat him after learning of his plans to unleash his army on a city. He hears from Sam of Michael's plans to unleash a monster army on a city, disgusted at the latter's intent.

 File:The Spear 05.jpg
He and the others split up with him joining Dean on locating the spear of Alternate Kaia. Castiel notices Dean's mood and becomes guilty at Dean stating they have a win with no problems, which causes him to recall his deal. When Kaia is able to get the drop on Dean, Castiel tries to advance on her but Dean stops him from attacking, telling Kaia that they have come to ask for the spear, not to try to steal it. Castiel watches as Dean makes a deal with her to give them the spear, but in exchange for bring Jack to open a rift as he did with her Main Universe counterpart. Kaia tells Dean and Castiel that they can find her again the same way they did this time and then vanishes as they are distracted by a phone call from Sam.

At Michael's headquarters, Castiel is detected by the Archangel and confronted by him. Castiel attempts to attack him though he effortlessly overcomes his attacks. The Archangel drags the wounded angel to his office where Castiel watches as Dean attacks him while armed with the Spear. Castiel is relieved that it might finally end, when Dean overpowers him but behaves strangely by breaking the spear and Michael's vessel falls dead. Castiel is speechless when its revealed Michael has possessed Dean once more, having left a way to enter his body without consent. Castiel asked why he waited so long to take back control and is disgusted by Michael's desire to break Dean's spirit and locking him away to prevent his interference. Michael taunts Castiel and the rest of Team Free Will by telling them, nothing stands in his way now and his monsters are on the prowl awaiting his signal, which he soon gives with a snap of his fingers.

During *Nihilism*, Castiel was angry at Michael's taunts and tried to attack but Michael caught him and told him not to interrupt before Sam distracted him with a bottle of holy oil that allowed Castiel to cuff the archangel. Castiel became worried as Michael's enhanced monsters started barging on the door as he and Jack tried to hold them off. He watched as Sam called for a Reapers to aid them in escaping, while Castiel couldn't see her but heard both Michael and Sam could. Soon, the group were teleported to the bunker, away from the monsters.

Afterwards, they wondered on what to do about the threat as Michael taunted them about his ongoing threat. Castiel spotted Jack speaking with the Alternate Michael and him leave while telling him not to listen to the villain. Castiel spoke with Michael who expressed his disapproval in Castiel for his ways and the latter asked how he could end a world without a thought. Castiel listened as the Archangel revealed his bitterness at how both his and the main God abandoned their creations. Castiel visibly disapproved of this mindset and by Michael's callous desire to kill God as well as end the world on a whim. He confronted Michael in Dean's mind and fought him but was overpowered, though helped in locking him away to prevent his evil from spreading.

In *Prophet and Loss*, it is revealed Sam told him about Dean's plan to lock himself in a Ma'lak Box, in spite of Dean telling him not to. They were both united in trying to persuade Dean into doing otherwise. Castiel also explained Donatello's status of being between life and death caused the creation of a premature and malformed new Prophet, Tony Alvarez, who killed two people and attempted to kill a third before killing himself. As a result, Castiel meets the Winchesters at the hospital while disguising himself as Dr. Novak. As the group decide to take Donatello off of life support, it is discovered that he is spouting the Word of God. Castiel realizes that Donatello's mind is trying to pull itself back together and as a result, he is no longer beyond help. Castiel searches through Donatello's mind while telling Dean that he found an alternative before he manages to awaken the prophet. As a test, Dean turns off Donatello's life support and he remains alive. After Donatello is taken off of the ventilator, he is confused as to where he is. Soon Dean and Castiel feed him some jello and Donatello requests buffalo wings. Castiel tells Dean that he is no longer the twisted, evil version he became, but Donatello still lacks his soul. Donatello shows no memory of his actions while corrupted by the Demon Tablet and Dean leaves Castiel to fill him in.

During *Lebanon*, Dean and Sam mention Castiel to John Winchester after he was pulled out of the past and he was amazed they live with an angel. Later on, an alternate version of Castiel is created as a result of John Winchester being pulled out of the past. Along with Zachariah confront the Winchesters, the alternate Castiel is shown to be the loyal soldier of heaven and doesn't know Sam and Dean who he attacks. This results in him being banished by Sam. Once John is sent back and history is corrected, the real Castiel returns to the bunker where he meets the Winchesters and asks what occurred as Dean promised to explain.

As of *Ouroboros*, Team Free Will are pursuing an elusive creature that had been killing people and leaving them eyeless. Later on, it is revealed to be a Gorgon. After another attack, Castiel and Dean find a note left by the gorgon who is Noah Ophis threatening them to stop. Castiel noticed the note didn't mention him, as they call the others with Sam realizing Noah can't see angels like him or Jack. Castiel deduced if he and Jack went after Noah, then he wouldn't prepared. Surely enough, they confront Noah who was preparing his latest victim and he realized his powers didn't work since they aren't human. Castiel watched Noah taunt Jack on now he can see Jack with his power before asking his reason and Noah says he's comparing Jack to the black snake and chicken. He then fights the duo and manages to overpower and paralyze Castiel. Noah then overpowers Jack and knocks him away until Sam and Dean arrive. As the Winchesters are overpowered, Jack tends to Cass and uses his powers to heal him before leaving to ambush and successfully kill Noah. The group rush Dean home while Castiel once again scolded Jack for his acts since he needed to preserve his life and also told Jack about their status of Cosmic beings and how they will lose those precious to them. Soon Castiel hears Dean awake and learns Michael disappeared. The group are alerted by the screams of the other hunters and see Michael possessed Rowena. Castiel tried to attack him but Michael stunned him and proceeded to torture him and his friends as revenge for trapping him. Michael would have killed him had Jack not taken a stance against him and eject him from Rowena, freeing Castiel from the Archangel's hold. Castiel witnessed Jack destroy Michael and was amazed that the latter was finally dead as well that Jack regained his powers.

During Jack in the Box, Castiel went to Anael about finding Jack but she refused. Castiel soon made his way to the Heavenly portal where he is confronted by Eremiel who refused to let him through. After a short bout with his brother, Castiel makes his way into Heaven where he knocks Eremiel aside and witnesses Jack turning humans into angels. Although amazed to see this he acts Duma for a word. After seeing her corrupt she is, Castiel takes his angel blade and kills his sister. He then goes to speak with Jack only to find that he’s gone.

He makes his way to the Bunker where he discovers that Sam and Dean have lock Jack in the Box only drove them further apart. Things get bad when Jack breaks out of the box and the alarm is issued in the bunker.

 File:Moriah 14.jpg
In Moriah, Jack has escaped the box and blasted everyone away without killing him. Castiel went to the demons for getting help to enter Hell. However, he is refused and he bemoaned his luck. At that point, he hears a voice and turns to se God. Shocked to see his father again, Castiel questions this and learns that God did pick up on his prayer and has return to handle the situation with Jack. Very soon, God takes him to see Sam and Dean. God explain the jacket canceled out everyone’s ability to lie and properly rectify the situation by undoing that. Got some reviews that he cannot restore Jack's soul and has made a gun called The Equalizer that can destroy. Castiel protests this but after the Winchester see no other alternative, he leaves the bunker angry.

At a cemetery, Castiel prays to Jack who immediately appears to meet him and the two talk. Jack tells him of his meeting with his grandmother and how he left without hurting her. Castiel then noticed Dean arrived, he tried to intervene but Jack knocks him aside. He watched as Dean was about to kill Jack, Castiel, despite clearly hesistant, was willing to fight Dean but was tossed aside by Jack. Even though Dean was ultimately snapped of his murderous rage, God, finally having enough, makes his presence known. Castiel then berated his father along with the Winchesters before God, having enough personally killed Jack. Castiel tended to Jack's corpse, as Sam shot God but this infuriated God, who triggered the Apocalypse. Together with the Winchesters, Castiel prepared to fight side-by-side against God's zombies.

### Season 15

 File:Back and to the Future 08.jpg
In *Back and to the Future*, Castiel and the Winchesters fight the zombies that God raised from Hell off together, with Castiel using his angel blade and Smiting to defeat the zombies, but despite their successes, Castiel, knowing they would be overwhelmed eventually, yelled at Dean and Sam to escape, with him taking Jack's corpse while Sam and Dean covered him until they reached the Carver crypt to regroup. Castiel confirmed he couldn't resurrect Jack or overpower all the zombies and his suggestion they burn their bones was immediately dismissed as their bodies could be anywhere, with Castiel awkwardly stating he wouldn't starve unlike Dean and Sam, which caused Dean to bitterly scoff at him and Dean then ranted to Castiel about how he knew God would do something like what he did, which Castiel could not reply to. Then, Sam thought that he found a way out after finding a drainage pipe behind a concrete wall but when it turned out to be a zombie, Dean asked Castiel's help to which the latter did, slamming the zombie's head with a rock and expelling the soul. Shortly after, when Jack's corpse reanimates. When Sam and Dean think its Jack resurrected, Castiel detected it was a demon and snapping, he slammed the demon to the nearest wall and demanded he get out of Jack's body. When Belphegor stated he can help, Castiel was still against Dean's desire to accept the help as he was an abomination who was defiling Jack's corpse but ultimately allowed the demon to talk. Donating his blood for Belphegor's spell, the demon expelled the ghosts from their bodies but noted they were not destroyed.

They rode on the Impala, with Castiel continuing to be in a bad mood due to Belphegor defiling Jack's corpse being allowed and expressing skepticism that he could contain the ghosts with magic but ultimately pointed out the spell could be cast on Kansas, who is less than a mile away from the cemetery.

In the morning, Dean and Castiel are left in the Impala with Belphegor. Dean suggested Castiel to help the demon work on the spell but Castiel bluntly refused, stating he couldn't even look at the demon who was taking on Jack's body and left Dean, who seemed to understand, to help Sam instead. Castiel and Sam went on to evacuate the townspeople and when visiting one of the houses, Sam was injured by a ghost possessing a clown but was saved by Castiel, who healed Sam. Castiel tried to heal Sam's bullet wound but could not as it contained energy he had never seen before.

Sam and Castiel soon fight off the ghosts with rock-salt bullets until Belphegor succeeds in his spell.

During *Raising Hell*, Castiel and the Winchesters along with Belphegor remain at the town to combat the ghosts, with Castiel remarking they won't be able to contain the ghosts forever as a man told him his wife had gone missing. Soon enough, they find her corpse, with Castiel wanting to tell the family but Sam refuses. When Rowena arrives, Castiel and Sam explained they need her help to create a crystal to contain the ghosts. When Andy snaps at Castiel as all his friends are missing, Castiel could not offer any comfort.

When Castiel is left alone with Dean, Dean shows how angry he is at Castiel for not telling him about Jack despite Castiel just apologizing and ranting on how Castiel had faith in God only to learn that God only wanted them to continue fighting for his own amusement, which Castiel took in stride, commenting on how he is no less hateful towards God for what he did. A frustrated Dean reveals on how he believes that they will not be able to defeat God, which Castiel disapproves, as though Chuck may have constructed the obstacles they faced, it was their way that they dealt with them, and insists that he believes their journey is real.

Castiel accompanies the others as Rowena captures the ghosts and watches silently as they ultimately succeed, although he is unable to heal Ketch's wounds after Dean shot him to get rid of Tumblety. Soon enough, however, Castiel and Rowena notice the ghosts increasing in numbers, effectively meaning they are still pressured since Belphegor's spell will eventually crumble.

After Rowena sacrifices herself in *The Rupture*, Dean finally completely snaps at Castiel as it was him who indirectly caused Rowena to have to do so by killing Belphegor before Lilith's Crook could suck all the souls back and admits freely to remaining angry at Castiel for Mary's death. Castiel finally decides to leave the bunker and the team as a result because of Jack being dead and Dean's anger.

In *Proverbs 17:3*, Sam notes Cass won't answer his calls.

As of *Golden Time*, Castiel is by himself a local police station. A woman recognizes him as an "FBI" agent and asks for help in locating her missing son. Castiel agrees to help and goes to the sheriff who wants prove of his status. Castiel is forced to call Dean when a hunt comes up and Dean begrudgingly helps him while telling Cass to call Sam. With that, Castiel goes to the last location and finds the mother has followed him for confirmation of her son's status. Castiel is forced to tell her of monsters before they find her wounded but still living son. They soon are confronted by the sheriff who is Djinn. He shoots Castiel but the bullets have no effect. Castiel voices his disgust for his acts before smiting him. Castiel then heals the wounded boy with his weakened powers and tells them to keep his secret.

In Our Father, Who Aren't in Heaven, Castiel prayed to Michael for them to talk about things. Michael caught onto the prayer and was angry at him for calling him Assbutt, setting him on fire and then helped send Michael to Hell, even worsened by how Castiel dared to say that Michael must help them fight God. As Michael speculates if Castiel has come to beg forgiveness, but Castiel denies it and surrounds the archangel in a ring of Holy Fire. As the Winchesters capture him with Supernatural Handcuffs, Michael angrily demands to know what Castiel has done. While Michael was detained, Castiel tried to speak with him of their father's betrayal but Michael refused to consider it. Later on, Castiel returned to Michael and admitted how he always disliked his eldest brother, but noted now he just pitied him for his continued misguided faith in trying to be the "good and favorite" son. At first, Michael was unfazed until Castiel berated Michael for not acknowledging he is just a puppet to their father, which finally enraged Michael who then attacked his brother for his words. While no match for Michael's strength, Castiel was nevertheless able to take the opportunity, with Michael focused on gripping his neck determined to hurt him for his words, to show the archangel his memories of God's betrayal. Castiel showed him how God was always around masquerading as the prophet Chuck, the fight with the Darkness, the murder of their nephew Jack and the Apocalypse World Michael. With this, Michael ordered him out to process this revelation. Afterwards, Castiel told Dean about this and the latter would voice his disagreement about Castiel's methods after Michael's reaction. However, both were surprised to hear an explosion from Michael's room. Michael became disillusioned with God, since he learned of the other Michael and decided to aid Castiel and the Winchesters. Michael told them of a ritual to seal God away and told them of a flower called Leviathan Blossom, which only grows in Purgatory. Michael opened a rift that will remain open for twelve hours.

 File:The Trap 08.jpg
During The Trap, Dean and Castiel worry for Sam until getting a call from Eileen and learning God captured them. Although Dean wanted to rescue Sam, Castiel prioritized getting the Leviathan blossom from Purgatory while the rift was still open. Reluctantly Dean agreed and the two traveled to the monster ram realm where they encountered a leviathan but they were able to defeat him. They interrogated him for answers and forced him to lead him to the location of the flower. Castiel also attempted to comfort Dean when they learn Benny was killed by vampires for his betrayal but Dean wouldn't have it. Losing his patience, Castiel confronts Dean on his previous behavior about Mary and Jack while Dean stayed firm in his behavior. However they are soon betrayed by leviathan who is determined to bring Cass to Eve for his part in the leviathan to defeat and sending her back to Purgatory. Dean is knocked out and find Cass gone and looks for him almost forgoing leaving the realm on time. Losing himself in his grief, Dean starts to pray and apologize to Castiel about everything, and declared him as his best friend. Dean makes his way to the rift before he finds a wounded but still alive Cass. The angel revealed that he managed to escape and heard Dean praying. With this, the pair make amends and escape the realm.

In *The Heroes' Journey*, Castiel is mentioned to currently be in Heaven seeing if the angels know anything about where God went.

During *The Gamblers*, Castiel returns to the bunker and discovers the Winchesters before he gets a call of a case. Castiel learns from a local sheriff of something that shocks him. A resurrected Jack has gone on a killing spree, ripping out and consuming the heart of Doctor Sariel. Upon examining Vic's office, Castiel uncovers an angel sword and realizes that the doctor was a Grigori.

Castiel tracks Jack to a church, where the last grigori is torturing Jack with his sword. Before things can escalate further, Castiel arrives and kills the Grigori with his angel blade, rescuing Jack. Shocked to see that Jack really is alive, Castiel unties his nephew and pulls him into a hug.

When Sam and Dean return to the bunker, they are shocked to see Jack with Castiel. After Castiel confirms that its really Jack, Sam pulls him into a hug before Dean holds him close and stares Jack in the eyes. Drinking beers, Jack explains that he wanted to return every day since his resurrection, but he couldn't as Jack can't use his powers without God knowing he's back and trying to kill Jack again. Billie kept Jack hidden in the Empty until God left the Earth at which point it was safe for Billie to resurrect him. Jack explains that eating the angel hearts is making him stronger, but he's not strong enough yet and so they must wait. If Jack follows Billie's plan, he will eventually become strong enough to kill God. This declaration shocked the Winchesters.

In *Galaxy Brain*, Castiel watched Sam and Dean get a call from Jody. After the pair return with Jody, and Dark Kaia, Castiel gets properly acquainted with Jody before he talks with the Winchesters about Kaia. He is against her wishes to use Jack to open a rift since that will cause God to become aware of his revival. Later on, Jack in the Winchesters decide to help Kaia by getting the reaper Merle to help Cass with the warding. Cass also forbids Jody from going to the Bad Place, since she is important to Claire and her death would devastate her. He stays in the bunker before the Winchesters return with Kaia. After Jody takes her home, the group ponder if God sensed Jack before Merle is killed by Billie. Castiel is shocked to see her as the new Death, as she brings up how they defied her wishes. Billie reveals God is destroying other worlds worlds to clean the slate of his ending for the Winchesters. Cass watches as the Winchesters question Billie on why she wants God dead. She reveals that when she became the new Death after Castiel killed her, something that he is self-conscious over, that she learned God had a book in her library. The contents of the book reveal Jack in the Winchesters are ultimately responsible for the destruction of God. Castiel was shocked to hear this news.

During *Destiny's Child*, the group are trying to figure out how Jack will kill God. Sam and Dean later tell Cass about meeting alternate versions of themselves with the arriving Billie telling its because they were fleeing from their world's destruction. Billie states God is nearly done destroying the Multiverse. Later, Cass shows Sam and Dean how their others are trapped between worlds. Billie reveals the next step for Jack: while eating angel hearts strengthened his body, Jack needs to find the Occultum which she states is more spiritual in nature. However, Billie doesn't know where to find it as it has been hidden and missing for centuries. Billie refuses to expand upon what it does beyond the Occultum being powerful and potent and not a weapon per se. Jack confirms that he is ready, pleasing Billie who states that they must be ready, vigilant and not stupid as God must not catch onto what they are doing.

As Sam and Dean go through the lore, trying to figure out where the Occultum is and more specifics of the plan, Jack enters, having just figured out how to pop bubblegum. Sam and Dean try to get more specifics out of Jack for how he will kill God when the time comes, but he clearly doesn't know. Castiel enters, having learned information from Sergei that points to Sister Jo having the Occultum.

After the Winchesters travel into Hell to find where Ruby hid the Occultum, a suspicious Castiel asks Jack to mostly kill him by draining most of Castiel's lifeforce so that Castiel can go to the Empty to talk to Ruby. Jack expresses concern about Castiel's plan, particularly as the Shadow doesn't like him and expresses concern that he may screw up in his soulless state. Castiel expresses confidence in Jack and warns Jack that he must continue to feed Sam's spell so that they won't be trapped in Hell. Jack reluctantly agrees to give Castiel an hour before bringing him back and draws Castiel's lifeforce into a flask. Returning to the realm of nothingness, Castiel encountered what appeared to be Meg until realizing it was The Shadow. After brief banter, it reluctantly allowed him to meet with Ruby. Castiel is directed to a pulsating mass that soon forms into Ruby who is surprised to see the Seraphim. Castiel tries to explain before Ruby remembers that she is dead and Castiel explains that he is almost dead. Castiel explains that he woke the demon up to find the Occultum and Anael told him that she had hidden it in Hell. Ruby is annoyed, pointing out that it is a little obvious for a demon to hide something in Hell. Castiel states that Sam and Dean are searching Hell now, causing Ruby to ask how Sam is doing, stating that she liked Sam and they had a good thing before her death. Ruby explained that Anael lied and tells the shocked Castiel that the Occultum is actually a place and Ruby explains that she and Anael cut a deal and she stashed the Occultum. Ruby states that she can give Castiel the location which is not in Hell after all. Castiel questions if Anael knows where it is, worried that the angel will seek out the Occultum, but Ruby reassures him that Anael doesn't know as Ruby knew that she couldn't be trusted. Ruby insists that Castiel can trust her to tell the truth, but requests that in return he gets her out of the Empty. Ruby points out that the Empty is full of sorrow and despair playing over and over in the inhabitants minds, angels and demons dreaming about their regrets forever. Having experienced it himself, Castiel knows what she means and Ruby requests that Castiel, who clearly has connections, at least try to get her out. Castiel promises to at least try and Ruby whispers the location in his ear. Afterwards, Ruby backs away and vanishes. With this info, Castiel tries to leave, though the Shadow, who is revealed to be working with Billie in exchange for sending it back to sleep when it's all over, tortures Castiel while he is still in its power, despite him reminding it of their dea;;. However, Jack returns Castiel's life force on Sam and Dean's insistence and Castiel vanishes from the Empty, returning to his vessel on Earth.

After returning from the Empty, Castiel reveals that he learned the Occultum's location from Ruby, pleasing everyone. However, Jack expresses worry about Chuck checking in on them, so the Winchesters bring in their alternate selves to pose as them in case Chuck visits.

Reaching the church indicated by Ruby, Jack notes that it all seems to easy before being ambushed by two hellhounds. Barricading themselves inside the church, the four search for the Occultum, eventually finding an orb beneath the floorboards stating in Enochian that "in order to be in the Occultum, the Occultum must be in you." As the others argue about what to do, Jack swallows the orb and is transported away in a flash of light. After Jack vanishes, the group wonder about this before holding off the hellhounds. Fortunately, Jack returns to the church in the form of an orb shortly thereafter, his return destroying the hellhounds as they break in.

After the Winchesters send their alternate selves away, Castiel has informs them that Jack has changed and he is the first being to visit the Garden of Eden since the exile of humanity. Castiel directs Sam and Dean to Jack crying in the kitchen, where he expresses horror over his inability to understand that Mary's death was his fault and Jack begs for Sam and Dean's forgiveness. As the Winchesters stare at Jack in shock, Sam asks what happened and Castiel explains that Jack's soul has been restored.

During *Gimme Shelter*, Castiel works a case with Jack. Castiel grabs Sylvia from behind and renders her unconscious. Castiel sends Jack to call the police while he heals Valerie's injuries. This causes her to wake up, surprised at her healed wounds while the Pastor is shocked.

The next morning, Castiel and Jack stand with Pastor Joe after informing him of what they are, as Sylvia is arrested for her crimes, unaware that the cop driving her away is Zack. Jack questions what will happen to Sylvia and Joe promises that no matter what happens, she won't be alone and he'll find a place where she can get help. Driving home, Castiel asks Jack about his hesitation to speak before and offers to help Jack shoulder his burden. Jack finally reveals that he's been lying to Castiel and the Winchesters: when he kills Chuck and Amara, Jack will die. Jack explains that Billie's spells have been turning him into some kind of bomb and when he goes off, Chuck and Amara will cease to exist. However, Jack won't survive it. Jack begs Castiel not to tell the Winchesters, knowing that they won't understand and believing that it is the only way that they will ever forgive him. Castiel refuses to lose Jack again, but Jack states that its not Castiel's choice.

In *Unity*, after Chuck criticizes the Winchesters for not playing their role. Chuck explains that he and Amara came to an understanding, and Castiel calls his father out on his actions. Chuck tells him to save it and says that all of the versions of himself did what they were told... except for the "real" Castiel. He angrily says that they're all too "broken" to do what he wants, and he's over all of them. The Winchesters don't care, and Chuck tells them that he's going to throw out his "broken toys". He doesn't care if they kill each other or not, and they can have fun watching Jack die.

In *Despair*, the group are worried about Jack before Billie appears and sends him to The Empty where he explodes. Castiel and Dean demand that Billie bring Jack back if he did in fact survive, but Billie refuses until she gets what she came for. She demands God's death book back from Sam, but Sam confronts Billie about the fact that she had always intended to betray them once they defeated God in order to take power herself and how "everyone who got a free pass or a second chance, everyone who was resurrected or came from another world, you were gonna kill them all -- Dean and me too." Sam accuses that of being the order she wants restored and her true endgame. Billie doesn't deny it and Castiel points how Billie lied to everyone, including the Shadow. Sam questions what would stop Billie from stabbing them in the back if he does give her the book, but Billie says that Sam has no choice as Jack won't last long even if he is still alive and if they want him back, Sam will give her the book now.

Sam reluctantly brings in the book, but drops it on the table instead of handing it to Billie directly. Billie opens the book to end, revealing that since they ruined the last one, the book has a new ending. Dean impatiently demands that she bring Jack back now, but she shushes Dean and just continues reading. Visibly pleased by what the book says, Billie comments that its interesting before bringing Jack back from the Empty. However, Billie states that Jack is hers as Jack is still useful.

Castiel watches as Billie prepares to take Jack and leave, until Dean grabs Death's Scythe and swings at Billie. Though Billie avoids a killing blow, Dean slashes her shoulder, causing it glow and Billie to drop Chuck's book. Flinging Dean away with telekinesis, Billie grasps her wounded shoulder and teleports away without Jack, the book or her scythe. When everyone they know disappear, Team Free Will believes its Billie and decide to defeat her. Castiel and Dean enter Death's Reading Room using the Key to Death armed with the scythe. Dean finds Billie standing at her table and she quips about it being the part where she greets him with "hello, boys" before doing so as Castiel emerges as well, armed with an angel blade. Billie mockingly asks if Dean intends to kill her with her own weapon, commenting that he'd better improve his aim. Dean states that he wasn't trying to kill her before, but now she's killing all of his friends. Calling it interesting, Billie flings Dean with telekinesis and begins choking Castiel before lifting him off of the ground. Billie grabs him and angry reminds Castiel of when he stabbed her in the back because she still holds a grudge. He is saved when Dean attacks Billie again with the scythe, pinning her to the wall and cutting her hand. As Billie struggles to keep the scythe away from her throat, Dean states that it's over and demands that Billie call it all off and stop killing his people. To Dean's shock, Billie reveals that she is not responsible for hurting Dean's friends and he is in the wrong place. Billie reveals that if people are disappearing, it's most likely Chuck who is responsible and thus Dean is just wasting time by coming after her. Billie then reveals that Dean had mortally wounded her earlier and shows Dean and Castiel her festering shoulder wound. As a result, while Billie doesn't care about Dean's friends and family, she now wants him dead and is pleased to have the chance to do so. Disarming Dean, Billie strikes him across the face and swings her scythe at Dean and Castiel who avoid the strike. Billie flings them with telekinesis and the two flee through the door back to the bunker with Billie chasing after them.

 File:Billie follows Dean and Castiel in the Bunker, to kill them.gif
As Dean tries to figure out what to do, Billie appears on the bunker's balcony, her wounded right hand now wilted and shaking and causes pain in Dean's heart. Chasing them, Billie calls Dean rule breaking and death defying and everything that she lives to set right, to put down and to tame. Dragging her scythe against the wall, Billie continues taunting Dean while casually strolling through the bunker after Dean and Castiel. Billie chases the two to the dungeon where Castiel puts up a ward in blood that blocks Billie's grip on Dean.

 File:A black tendril reaches out from a portal and pulls Castiel and Billie into the Empty.gif
Undaunted, Billie begins pounding on the door causing the sigil to start flashing as Billie slowly breaks through it. Castiel suggests that they can wait Billie out since she is already dying from her wound and if they can't, they fight. Dean knows that they'll lose and that he just led them into another trap because Dean couldn't hurt Chuck and so needed something to kill instead due to his anger. Realizing that he has one final card to play, Castiel notes that Billie is afraid of something powerful enough to take her: The Shadow. Castiel decides to summon The Shadow and finally tells Dean about the deal that he made with it in *Byzantium*. In his speech, he tells Dean that he is the most selfless, loving human being that he will ever meet and that him caring for Sam, Jack, and everything was because of Dean, admitting that he loves Dean. Dean is left both touched and stunned over Castiel's confession but this soon shifts into horror and devastation as he realizes what Castiel's plan is: confessing his feelings for Dean has triggered Castiel's true happiness to summon the Shadow to take both him and Billie to the Empty. Dean pleads with Castiel to stop but it's too later and Castiel tosses Dean aside just before The Shadow takes him to The Empty while smiling, crying and accepting his fate. He is then to taken to the Empty along with Billie.

In *Inherit the Earth*, Dean sadly tells Sam and Jack that Castiel is dead, clearly still devastated by the death of his best friend, on the verge of tears. Jack later said his name in sadness, before breaking into tears. Much later, a resurrected Lucifer masqueraded as Castiel using his voice in a call to a surprised Dean. After God was defeated and drained of his powers by Jack, Dean carved Castiel's name into the table to remember his sacrifice.

During *Carry On*, Dean dies and ascends to Heaven where he meets Bobby who implied that Jack has resurrected Castiel. He stated Castiel is currently helping Jack to reshape Heaven to be a much better place, with Dean smiling upon hearing his best friend was saved from the Empty after all.

## Powers and Abilities

### Original Abilities

 File:Castiel wings.gif
Since his first appearance, Castiel has possessed astounding abilities and is one of the most powerful supernatural beings the Winchester brothers have ever met. Castiel has shown to possess all the powers of regular angels – including entering human dreams, smiting demons, telekinesis, teleporting and transporting others and himself through time. Uriel seemed so sure of Castiel's powers that he felt confident that if Castiel joined him and his fellow rebels, they would be powerful enough to challenge Heaven and free Lucifer from his Cage. Even Anna Milton, despite having once been Castiel's superior, chose not to directly confront him after Castiel appointed himself as the Winchesters' guardian. Instead, she went back through time in an attempt to ensure that Sam and Dean are never born, although Anna retained her smiting ability while disconnected to Heaven while Castiel did not, showing that Anna was stronger. Even when not at full strength and when weakened by being cut off from Heaven, Castiel was apparently quite powerful by even angel standards and was shown to be a very capable fighter, as he was able to take on and defeat several, at least over half a dozen, of his angelic siblings by himself when he was fighting to prevent the Apocalypse.

These were Castiel's powers as a common angel. Some of this power depended on his link to Heaven.

* **Angelic Possession** – As a spiritual being, like all angels, Castiel needs to use and possess a human vessel to physically interact while on Earth. As an angel, he requires the vessel's permission.
* **Astral Projection** – Castiel is able to partially project his true form while inside his vessel, which appeared at the end of the Season 4 episode Lazarus Rising as shadows of his feathery wings on his back to show Dean proof that he was in fact what he claimed.
* **Chronokinesis** – Although he has said it is difficult for him, even with the powers of Heaven at his disposal, Castiel can travel forward and backward in time, and he can take passengers.
* **Dream Walking** – Castiel appeared in Dean's dream to deliver him a message.
* **Electromagnetic Interference** - Castiel caused a dozen car alarms to stop by raising his hand.
* **Healing** – Castiel can instantly heal the wounds and diseases of humans. Castiel has saved and healed both Sam and Dean many times from their wounds. As a fallen angel, he was not able to heal.
* **Immortality** – Castiel, as an angel, like all celestial beings, doesn't age over time and is immune to disease. He never tires, and does not need to eat, sleep, drink, or breathe to sustain himself or even his vessel.
* **Regeneration** – There are very few things able to permanently harm or kill Castiel, as he has repeatedly shown the ability to quickly, if not instantly, heal and regenerate from any non-supernaturally inflicted wound or ailment, regardless of its fatality.
* **Invulnerability** – As an angel, Castiel is entirely immune to most, if not all, means of physical harm, at least they be enhanced by magical or otherwise supernatural means. In his first appearance, he was completely unfazed by several shotgun blasts and being stabbed by the Demon-Killing Knife. Later, when Dean Winchester punched him out of anger, Castiel barely flinched and the impact sounded as if Dean had punched a piece of metal. An alternate version of Castiel seemed to possess a similar level of invulnerability as he was unbothered by several attacks from Dean, including being bashed in the head by a piece of steel kitchenware.

* **Smiting** – Castiel possesses the ability to kill or exorcise a demon simply by touching his palm to the forehead of its host. He is able to kill lower-level demons and other beings like monsters with a simple touch. When this happens, a strong white light appears from the eyes and mouth of the victim and burns them from the inside out. This ability does not work on demons stronger than Castiel as Alastair proved to possess complete immunity from such an attack. Lost the ability when he became a fallen angel as it came from Heaven, but regained a more powerful version after his second resurrection.
* **Resurrection** – Castiel brought Dean back from the dead. He lost the ability when he became a Fallen Angel as it came from Heaven.
* **Sedation** – Castiel can cause instant unconsciousness in humans by tapping them or simply placing two fingers on their forehead.
* **Localization** - As an angel, Castiel is able to track and locate beings, although not if they are warded by Enochian sigils. He can track warded person's location if they pray to him.
* **Pyrokinesis** – Castiel displays the ability to burn through ropes binding him.
* File:Punch-uriel.gif  **Super Strength** – As an angel, Castiel is physically much stronger than humans, ghosts, monsters, lesser angels, and most demons. Though he typically seems to attempt to avoid fighting, he is a very formidable physical opponent when need be, and is unstoppable when facing mortal beings. He proved capable of overpowering common angels and humans with ease, and he once beat Dean to nearly a bloody pulp. Although incredibly strong in his own right, an angel such as Uriel or a high-level demon such as Alastair had superior levels of super strength. As Uriel exhibited superhuman strength when battling two demons in the episode Heaven and Hell, Castiel most likely possesses such physical power as well. Also his strength has been seen in numerous episodes, and he is shown be quite strong. In the episode On The Head Of A Pin Castiel was able to send Uriel flying through a wall. However, he was no threat to archangels. An alternate timeline version of Castiel displayed a similar level of strength, able to effortlessly overpower and throw Sam and Dean Winchester around like ragdolls.
* **Astral Perception/Senses** - Castiel can see things hidden to humans. Castiel's vision and hearing are at extreme superhuman levels; he was able to see a symbol on a person's heart that was so small Sam needed a microscopic lens to see it. He also has an amazing sense of taste and is able to taste every molecule in a piece of food.
* **Telekinesis** – Castiel has the ability to move objects and even people with his mind, imparting kinetic energy on matter with his mind. He used this to twist Ruby's Knife into Alastair's wound after having stabbed him with it. He later uses this power to unscrew a bolt from a distance.
* **Telepathy** – Castiel is able to read the minds of humans and other lower-level angels.
* **Voice Mimicry** – Castiel once perfectly imitated Bobby Singer's voice.
* **Protective Charm** – Castiel is able to protect someone from harm beforehand, as seen when he prevented his vessel, Jimmy Novak from burning his hand on a pot of boiling water when asked for a sign of faith.
* **Spell Casting** – As an angel, Castiel has extensive knowledge of Enochian symbols and spells which he has used for a variety of effects. He could draw an Enochian Devil's Trap that could completely suppress and bound a demon as powerful as Alastair. He also knew of symbols that could banish or ward off angels. After his first resurrection, he branded Sam and Dean with a pattern of symbols that would conceal them from every angel in creation, even one as powerful as Lucifer. He later did the same to Adam. Castiel was also capable of casting various tracking spells.
* File:17-Supernatural-Season-Ten-Episode-Fourteen-SPN-S10E14-The-Executioners-Song-Castiel-Misha-Collins.jpg  **Holy White Light** **(granted by another angel's grace)** – While possessing the grace of an unknown ranking angel, Castiel displayed this ability, using it to blast a door open and then again on Cain. However, being the very first Knight of Hell, the latter was so powerful the blast of light merely ruffled his hair.
* **Lie Detection** - While powered by Adina's grace only, Castiel was able to sense that the now-human Metatron was telling the truth when he admitted to previously lying about knowing a cure to the Mark of Cain.
* **Limited Cosmic Awareness** – As an angel, Castiel possesses a superhuman level of intelligence. He explained the reason of his chronokinesis limits by partial differential equations, that shows that he has highly advanced understanding of mathematics, explicitly of mathematical calculus and differential geometry. Like other angels he has vast knowledge about celestial related things such as the weapons of heaven, prophets, others types of angels and nephilim. He also retains knowledge about spells and symbols.

### Seraph Abilities

> I do believe he brought me back. New and improved.

> Castiel to Dean, *Swan Song*

 File:Tumblr mnsdkyWMHQ1qkmxp8o2 500.gif
After he was killed by Lucifer during the Apocalypse, God resurrected Castiel and endowed him with new and stronger powers, making him more powerful than before, as he said, "*I do believe he brought me back. New and improved.*" Castiel reveals in *Blood Brother* that he's now a Seraph, a higher species of angel. Not only has he gained greatly enhanced powers – including healing, resurrection, teleporting, smiting, Reality Warping, Soul Channeling, Soul Reading, psychokinesis removal and chronokinesis – while retaining all previous ones, but now he is independent from Heaven and could function with his powers independently of Heaven. This means he retains his full powers and angelic grace despite being a Fallen Angel and cut off from Heaven. His growth in power and strength is emphasized by the fact that when he was a regular angel, an angel of similar rank, like Uriel, was capable of beating him, but in the seasons following his promotion to Seraph, even groups of angels are incapable of killing him, although they are likely lesser angels and are naturally weaker than him. At times, he has been able to completely overwhelm and brutally slaughter his angelic siblings, as seen when Hannah's angels were torturing him, but he broke out and killed them after they murdered Hannah, though his strength may have been partially due to the Attack Dog Spell Rowena had cast on him.

Initially following his rescue from Purgatory, Castiel appeared weakened from his time in the monster realm as he is quickly drained from using his powers such as teleporting or killing a low-level demon. However, this seemed to be temporary as he later but quickly recovered his full seraph abilities. After Metatron took Castiel's grace, Castiel lost his angelic powers (excluding hearing angel radio and recognizing other angels) and was rendered human and powerless. Castiel has recently gotten what is left of his grace back and has stated he is back to full power, though he has broken wings, making him a Seraph again. Although over time after The Fall, he stated that his powers are failing, though it is unknown if this was due to The Fall even though he wasn't directly affected, only having regained a portion of his original Seraph grace or the extended time he has been disconnected from Heaven due to The Fall. His Seraph abilities include:

* **Immortality** – Castiel is immune to age and illness as well as most forms of physical harm on earth.

 File:Castiel full power.jpg
* **Astral Projection** – As a Seraph, Castiel's true visage is far more hazardous and far more terrifying to creatures such as humans, demons, and other earthly monsters. Castiel was able to combine this with the use of his white light even while in a weakened state to force the King of Hell Crowley to retreat.
* **Astral Perception/Senses** - Castiel is capable of immediately discovering a person's identity or their prior medical status by simply smelling their remains, regardless of the condition of said remains. He is also capable of speaking to and understanding animals, as well as listen in on radio frequencies. He saw the true faces of demons from a far enough distance that Dean needed binoculars. Castiel was able to tell that the boys had chosen the bone of Sister Mary Constant just by sniffing it, he was also earlier able to tell that Meg had indeed killed two demons just by sniffing the knife she used, he heard what Sam and Dean were saying from another room. Castiel can also identify genes and hormones in human beings, as he was able to tell a man was gay by looking at him. Castiel was able to perceive Chuck in Donatello while he was speaking to him and the boys in the Bunker.
* **Electromagnetic Interference** - By having his finger pulled, Castiel caused all the lights in his room to shatter.
* **Intangibility** - As a spiritual being, Castiel can phase his vessel through solid matter, exemplified when he tested if Sam's soul was present without leaving any physical effects.
* **Invisibility** – Castiel can become invisible to humans. He used this ability to spy on Dean living a normal life and again when trying to see how much Dean, Sam, and Bobby have learned about him and his alliance with Crowley.
* **Telekinesis** – Castiel has the ability to move objects and even people with his mind, imparting kinetic energy on matter with his mind. His telekinesis seems to be much stronger than when he was an angel, as he could even fling a Leviathan against a tree, a noteworthy feat due to Leviathan's being resistant to the majority of angelic powers.
* **Mental Manipulation** – By placing his hand on a person's forehead, Castiel is able to manipulate a person's mind, being able to create, erase or alter memories or simply alter their perception of events altogether. He easily tore down the mental dam inserted by Death on Sam that protected him from the memories of him being tortured in Lucifer's Cage. Though he was unable to cure Sam from the resulting madness it caused, he was able to transfer the mental damage from Sam to himself. He is also able to show a person the true version of their memories, not just the version they choose to remember. This is shown when he makes Dean see what really happened when he escaped Purgatory. Later, Castiel stripped the ritual to open a rift from the mind of Donatello Redfield, but doing so left Donatello brain dead. However, after Donatello's mind started to reconstitute itself, Castiel was able to finish the process and bring Donatello back to normal. As a method of torture, Castiel was able to use this to inflict great pain on a rogue resistance member.
	+ **Memory Manipulation** - Castiel allowed Sam and Dean to remember the events of the alternate timeline that was created with Balthazar prevented the Titanic's sinking. He erased the memories Lisa and Ben's memories of Dean, after Dean asked him for a favor. He also showed Michael all the visions of God's betrayal.
	+ **Dream Walking** – He was able to enter Fred Jones' dream and take Sam with him.
	+ **Telepathy** – By touching Rowena's forehead and concentrating, he was able to see her memory of Oskar.
	+ **Mental Projection** - Upon his return from Purgatory, Castiel attempted to reach out to Dean mentally, causing images of Castiel to appear on the side of the road and at a window. However, due to Castiel's weakened state, these images lasted too short a period of time for Dean to investigate them or be sure they were real.
	+ **Animal Communication** – Castiel was able to communicate with a cat.
	+ **Lie Detection** - At the request of Arthur Ketch, Castiel was able to sense that he was not lying to the Winchesters at the moment to ease their doubts about him.
	+ **Mind Control** - By touching his hand to a Secret Service agent's forehead, Castiel was able to make him believe that there was no one in a motel room but Kelly Kline and ordered him to wait in his car. The effect only lasted a few minutes.
* **Sedation** – Castiel can cause instant unconsciousness in humans by tapping them or simply placing two fingers on their forehead.
* **Pyrokinesis** – Castiel can now no longer just create fire, but he can manipulate and extinguish it effectively. Castiel displayed this ability when he extinguished the circle of holy fire that trapped Balthazar.
* **Reality Warping** – Castiel, in one instance, altered reality, by shaking a 'Sorry' board-game, and having everything instantly set up. He was later able to fill a vial with his blood just holding it tight in his hand and not making any cuts. Also he was able to change his appearance and clothes into his original one after returning from Purgatory, and he apported every hair and fiber of dirt off his face and coat.
* **Power Negation** - He was able to strip Fred Jones of his powers, although the process severely damaged Fred's mind.

 File:A whore is a whore is a whore by spn castiel-d3fyhnk.gif
* **Super Strength** – Being a Seraph, Castiel has exhibited higher levels of physical strength than he did as a common angel. He is capable of overpowering humans, ghosts, monsters, demons and even his angelic brethren with greater ease, as seen against Raphael's soldiers or against his former friend Rachel. He also once easily forced the demon Crowley against a wall, despite the latter's position as the King of Hell, and left an impression on the wall. In addition, he once again beat Dean to a bloody pulp. However, against the Archangels, such as seen with Raphael, Lucifer and Michael, as well as the Alternate Michael, and Princes of Hell, such as Dagon and Ramiel, Castiel was no match for them, as all the four aforementioned individuals had easily beaten him to a bloody pulp, with Alternate Michael effortlessly knocking him out with a single punch while the real Michael could restrain him even when cuffed with Supernatural Handcuffs with ease, although Castiel was strong enough that while Lucifer was weakened due to his depleted grace, he was able to injure him and briefly held his own while Lucifer's strength was reduced because of Vince's deteriorating body, although on the former he was still unable to defeat him and had to escape and in the latter, Lucifer was still quickly able to pummel him. Neither was he a match for cosmic beings like The Darkness, The Shadow, or Billie as Death, with Amara effortlessly overpowering Castiel's attack and tossing aside Castiel with a single hand, the Shadow effortlessly beating Castiel twice, and Billie easily lifting and strangling Castiel one-handed without him able to break free, despite Amara and Billie being weakened. Though he could still be outmatched by the Leviathans, Castiel proved capable of standing up against them. In Purgatory he managed to hold off two Leviathans, overpower and ultimately incapacitate them with Dean's help. He was also able to overpower his Leviathan captors when he and Dean returned to Purgatory for the Leviathan Blossom enough to escape. Castiel also proved to be strong enough to lift a 1-ton anvil with ease and was also able to rupture a stone wall just by merely touching it. Even in a weakened, injured and trapped state, he was able to overpower and kill Efram along with Jonah. As a seraph, Castiel's strength is sufficient to overpower multiple regular angels at once in combat. When he was attacked by an Angel named Duma and her henchmen, Castiel was easily able to outmatch them, with the Angels only winning the fight when Duma caught him by surprise from behind. Even after Duma became the Ruler of Heaven, Castiel was confident that he could surpass her strength, with Duma choosing to threaten Mary and John rather than challenge him. Castiel easily overpowered Eremiel and even threw the other angel across a room effortlessly. While working a case with Jack Kline, Castiel effortlessly snapped thick ropes and several metal braces which were restraining a victim.

 File:Smiting.jpg
* **Smiting** – Castiel's angelic killing touch became much more powerful after his resurrection. He could instantly kill several demons with great ease by using this ability. He was also capable of killing various monsters using this ability such as creatures even in Purgatory. He tried to smite a Leviathan in Purgatory, but he was unable to, due to negation of his powers. It is unknown if he could've smote a Leviathan when his powers were not blocked. Though Castiel retains this power, in later years he switched to angel blades for killing demons until he smote Dipper and later one of the Bunker Incursion Demons. He also proved capable of smiting zombies. Castiel displayed an exceptionally powerful version of smiting when he killed the demon Belphegor. The smite completely incinerated and charred the demon, and unintentionally destroyed Lilith's Crook.
* **Healing** – Castiel has displayed the ability to not only heal any wound, but can also cure people of both physical and psychological diseases. He was able to heal Kevin Tran of his wounds and was also able to regrow cut-off limbs as he did with Kevin's finger. He easily cured Charlie Bradbury of her carpal tunnel while simultaneously healing a bullet wound, though he suggested she still wear a wrist brace at night. On one occasion while healing a gunshot wound his hand glowed though he usually heals without any visible sign besides the injury healing, but the bullet was stuck inside that man's body. There are some things even he can't heal. According to Castiel, Sam was damaged on the subatomic level from his trials and it was beyond his power to fix that. Despite his fully restored powers, Castiel was unable to heal the damage a Grigori did to Amelia Novak, something that stunned him as he'd never encountered that problem before. He was later able to heal Ishim of a deep angel blade wound. While the healing left Castiel weakened, Ishim felt better than he had in a millennia afterwards. Castiel healed Dean's broken arm from Dagon without trouble and Shaggy Rogers broken arm as well. After Dean suffered an injured leg from a grenade launcher explosion, Castiel healed it, at the same time healing Dean's cuts and bruises from a fight with Arthur Ketch. However Castiel could not heal the deceased security officer killed by Jack in an accident. It is unknown if he was able to resurrect him or not. Castiel was also unable to heal Arthur Ketch after Dean shot him, for a presently unknown reason, more than likely due to his failing powers as it was after this event and the stopping of the Ghostpocalypse that he noted to Dean his powers were failing. While working a case with Jack Kline, Castiel fully healed three of a victim's fingers, which were previously severed.
* **Regeneration** – Like any celestial being, Castiel has accelerated healing abilities. He can instantaneously regenerate from injuries caused by earth-based weapons. However, he takes somewhat longer to heal damages caused by Angelic Weaponry. When shot by a bullet made by melting and repurposing an Angel Blade, once he removed the bullet, he regenerated, but it took time. He has also displayed the ability to quickly recover from harsh beatings delivered by stronger supernatural being such as the mark-enhanced Dean, Lucifer, (Notably having completely recovered by the time Lucifer left Vincent Vincente whereas Crowley was still badly bruised and left with a black eye), and the Alternate Michael.
* **Resurrection** - Castiel easily resurrected Bobby after he was resurrected again as a Seraph by God. By locating Jack's soul in Heaven, Castiel was able to resurrect him long enough for Jack to perform a ritual to cure his fatal condition, bringing him back permanently. However, without the ritual to cure Jack's condition, Castiel lacked the power to bring Jack back for more than a few moments and when Jack returned, he was still sick before the ritual was performed.
* **Biokinesis** - Castiel was able to cure Dean in order to prevent him to become a Jefferson Starship.
* **Localization** - As a seraph, Castiel is able to track and locate beings, although not if they are warded by Enochian sigils. He can track warded person's location if they pray to him.
* **Clairsentience** - He was able to detect Fred Jones' power when he was searching for him. He could detect the presence of the Cosmic Entity while in The Empty stating he could feel it. He could detect that the warding of the Bunker was still intact despite God's intrusion. He can also detect where he is, as he was able to sense that he and the rest of the team were in Northeast Kentucky after traveling to the Apocalypse World.
* **Vessel Locking** – Castiel has displayed the ability to grab a demon's smoke form and force it back into its body to smite it.
* **Soul Reading/Channeling** – By pushing his hand into a person's chest, Castiel can determine the presence and condition of a person's soul, and if the soul was branded by a deal. He can also siphon energy from or completely absorb a soul to recharge and enhance his powers. The process is extremely painful and delicate, having been noted by Castiel as putting one's hand into a nuclear reactor and causing the person to explode should anything go wrong. Castiel displayed this ability to see that a boy had sold his soul to Balthazar and again to see how damaged Sam's soul was after it had been tortured in Lucifer's Cage. He used it to search Sam's body and later informed Dean that Sam's soul wasn't there. Castiel displayed this ability to strengthen himself with 50,000 souls from Hell and again when he absorbed all the 30-40 million souls of Purgatory to evolve into a mutated angel.
* **Leviathan Perception** – Due to having been used as a vessel for the Leviathans, Castiel can see past their vessels and shape-shifting abilities and correctly identify them. This ability allowed him to identify the real Dick Roman, so he and Dean could kill him. While in Purgatory, Castiel was able to sense the presence of two nearby Leviathans before they could attack the group while Dean and Benny were completely unaware of them and later sensed two more approaching as he and Dean neared the escape portal. File:Casvscrowley.jpg
* **Holy White Light** – When Castiel became a Seraph, his holy white light became stronger and more glorious. He used this power to kill a dozen Jefferson Starships. Even while weakened by his time in Purgatory threatening to use this power against the King of Hell Crowley along with displaying his wings caused Crowley to retreat.

### Soul-Enhanced Abilities

 File:SPN 0149.jpg  In order to fight the war against Raphael, Castiel made a deal with Crowley for a loan of 50,000 souls, which enhanced his powers and allowed him to launch the first strike against the archangel. After absorbing the millions of souls from Purgatory (including a large number of Leviathans), Castiel was endowed with god-like abilities that made him both highly dangerous and unstable due to the power intoxicating him and clouding his judgment. During this time, his power exceeded that of the Archangel Raphael and he was confident enough to challenge Death, although Death simply dismissed him as a mutated angel and found him as insignificant as everyone else, implying he couldn't actually challenge him and it was just arrogance (though it was never explained if it was indeed possible for Castiel to defeat him or not).

His new powers took a serious toll on his vessel, as it started to melt as a result of him being unable to contain that much power in his physical form. Death had also referred to him as a mutated angel, which was noted by the lack of the common sound of wings flapping when he teleported from place to place and he did not even bleed at all like usual as shown when Sam stabbed him.

After absorbing millions of souls from Purgatory, he became so powerful that he was able to overpower an Archangel easily, his powers included:

* **Lower Tier Nigh-Omnipotence** – After absorbing souls in Purgatory, Castiel became one of the most powerful beings in the universe, as the souls endowed him with unspeakable power, allowing him to do almost anything he wished. He effortlessly obliterated the archangel Raphael with a snap of his fingers and later killed thousands of angels who were Raphael's followers in Heaven. He could also kill humans with a single thought or word; such as when he said to a hypocritical church preacher, "*He who lies in my name shall choke on his own false tongue,*" causing the preacher to literally choke on his own tongue. As well as perform miracles like making the blind see, curing an entire colony of lepers, exploding a publishing house, causing lightnings to burn down a motivational enlightenment center, smiting Madison square garden, killing 200 religious leaders, changing a church window to his image, scorching a seat, causing a man to sit down hard enough to break the seat, turning off Crowley's TV in his presence and unbound Death with a snap of his fingers. Castiel even told Crowley of his initial intention to eliminate Hell, an entire spiritual realm. However, Death was mostly unconcerned by Castiel's new-found powers and openly mocked him, saying he was no God, but instead calling him a "mutated angel." Also, despite his new-found power, Castiel was willing to keep Michael and Lucifer sealed within the Cage.
	+ File:Whitelightcastiel.jpg  **Holy White Light** – Castiel was able to emit a powerful white light from the palm of his hand in a similar fashion to that of an Archangel. He used this power to temporarily banish Raphael. With 30-40 million souls, he was able to emit an enriched pulsating light from his vessel.
	+ **Power Negation** – He was capable of neutralizing the power of other creatures, including an Archangel's powers. This rendered Raphael helpless.
	+ File:Raphael implosion.gif  **Molecular Combustion** – With a snap of his fingers, Castiel was able to render Raphael down to his component molecules, killing him in an explosion of blood and gore.
	+ **Spell Negation** – With a simple snap of his fingers, Castiel was able to break the powerful spell that Sam, Dean and Bobby had cast to bind Death, something even the latter was unable to do, although the fact that he was bound was probably at least partially responsible for this.
	+ **Sedation** – Believing himself to be the new "God", Castiel confronts a reverend whose views he deems hypocritical. When a parishioner attempts to stop Castiel, he renders him unconscious, breaking the church pew and forcing his body down.
	+ **Smiting** – When Castiel absorbed all the souls in Purgatory he smote Madison Square Garden and all angels who were on Raphael's side.
* **Nigh-Invincibility** – Due to his massive absorption of the Purgatory souls, Castiel became immune to nearly any form of harm as seen when he was unfazed from being stabbed in the back by an angel blade. After turning into a mutated angel, he was no longer vulnerable to angelic blades or any other angelic weaknesses. However, Death and God were still more powerful than him. He was also vulnerable to the mass of souls and Leviathans inside him, which, according to multiple individuals, would eventually cause Castiel's human vessel to explode due to his inability to properly contain so many souls and control all of that power.
* **Immunity** – Castiel became immune to nearly any form of harm as seen when he was unfazed from being stabbed in the back by an angel blade. Enochian signs were now useless against him as seen when he tracked down and cornered Crowley in his sigil-covered trailer.

### Powers Granted by Jack

While briefly empowered by Jack, Lucifer's son and a powerful Nephilim, Castiel displayed a few powerful abilities during this period. Castiel only possessed these powers while holding hands with Jack's mother and lost them once the connection was broken.

* **Super Strength** - During this period, Castiel became strong enough to effortlessly restrain the Prince of Hell Dagon who had easily beaten him in a fight when he was relying on only his Seraphim abilities.
* **Power Negation** - During this period, Castiel was able to render the Prince of Hell Dagon completely powerless.

 File:Dagon's Death.gif
* **Pyrokinesis** - During this period, Castiel was able to burn the Prince of Hell Dagon to ashes, killing her, a feat not previously seen performed by any other character.

### Other Abilities

In addition to his considerable angelic powers, Castiel also has other formidable skills, not a few of which his angelic siblings lack, acquired both from his combat training in Heaven and hunter training and interaction with the Winchesters.

* **Indomitable Willpower** - Castiel has displayed a tremendous amount of mental strength throughout the series. Despite his initial misgivings, he eventually was able to muster the willpower to rebel against Heaven after seeing how far Heaven had become corrupted and despite Lucifer still being released, Castiel was able to keep fighting with vigor and even despite his anger at Dean for trying to make his sacrifice in vain, Castiel only vented up on Dean and did not give up, even without hesitation attempting a suicidal plan by taking on 4 angels.
* After becoming a Seraph, despite God refusing to respond and feeling deeply guilty over having to betray and deceive the Winchesters, Castiel was still able to continue his civil war with Raphael and efforts to find Purgatory until he finally managed to win the war and gain all the power of the souls inside for himself. Even after all the destruction he caused and becoming temporarily insane, Castiel was able to eventually muster the strength to help Dean defeat the Leviathans and keep on living, drawing on his desire to achieve redemption.
* Castiel even managed to temporarily overpower Lucifer's possession over him to save Sam, a truly astonishing feat, though he proved to be inferior in this regard to Sam as he had to use all he had to keep him at bay and could not expel Lucifer.
* Castiel did not give up on saving either Dean or the soulless Jack even as Dean was possessed by Michael and wreaked havoc and Jack killed Mary, persisting on saving Dean even after Michael repossessed him, even able to overcome Michael's attack with sheer rage, a remarkable feat as even Sam was left paralyzed, and refusing to let Jack be killed even though God himself said that Jack cannot be fixed.
* Even after God killed Jack and caused the second Apocalypse, Castiel remained as determined as ever to stop God and despite wanting revenge, Castiel was able to just barely muster the willpower to resist the temptation to kill Belphegor for defiling Jack's body to stop the chaos and even disfigure Jack's corpse to kill Belphegor and as always, even after he was estranged with Dean after Rowena's death, Castiel was still able to remain determined to protecting the world.
* **Master Hand-to-Hand Combatant** - From the beginning, Castiel was already a highly accomplished fighter, deemed to be among the best of Heaven's soldiers. His skills are sufficient to fight against stronger beings, as he was capable of landing vicious blows on Alastair before getting overpowered by him in both their altercations, and outfighting Uriel, able to hit him more than Uriel did and only losing due to his superior strength and getting surprised and hit with a crowbar.
* Even as a fallen angel, Castiel's skill more than made up for his diminishing power against his fellow angels, as he gave one of Zachariah's angels, armed with an angel blade, a swift trashing before killing him with his own angel blade, and easily thwarted a surprise attack from one of the angels guarding Adam's resurrected body, disarming him of his angel blade and using it to swiftly kill the angel. This skill, in addition to his powers greatly increasing after he became a Seraph, has only improved over the course of the series, partly due to his time spent with the Winchesters who are formidable combatants themselves and his brief time spent as a Hunter-in-training.
* His skills are shown in his fights against other inhuman beings, as he is able to disarm many beings with Angelic weaponry and then use that weapon to kill them. He has proven capable of fighting his lesser angelic brethren with ease, shown when he easily defeated one of Raphael's followers despite the latter having just disarmed and was using his angel blade against him when he had just determined Balthazar's location, forcefully tossing away the blades the angel was using against him and tossing him out of the building alongside himself, overpowered and killed Rachel despite having been injured by an angel blade, swiftly defeated Bartholomew unarmed despite holding back and Bartholomew wielding an angel blade, easily dominated Duma and two other angels simultaneously before being caught off-guard, effortlessly beat Eremiel despite him being armed by an angel blade, and even while his hands were restrained by the Supernatural Handcuffs and he was weakened from torture, swiftly overpowered and killed both Jonah and Efram.
* Castiel had also displayed the ability to use his skill to fight against stronger beings, as shown when up against two leviathans and surprised, after recovering from the harsh beat down, he managed to toss aside one and then punch her for Dean to decapitate her, in addition to also being able to force back Magog unarmed before using his angel blade against Magog's sword, surprise and knock Lucifer away from Sam before being soundly pinned down when he fought him alongside Sam and Dean, briefly hold his own against him when his vessel was deteriorating and even managed to force Lucifer to escape from him when Lucifer's grace was considerably reduced, although the fight left Castiel injured enough to pass out. This skill remained with him even as he became human, as he managed to kill an angel in a broken bus without his powers, although the angel was caught off guard at the discovery that Castiel was now human.
* Due to his superior strength, Castiel could easily defeat and beat Dean to a pulp, doing so twice, once before even becoming a Seraph and an alternate version of him easily beat both him and Sam, although it must be noted that Dean was surprised and trying to reason with him and still managed to land blows. Over time, his fighting skills, as they continued to improve, even reached the level from when he briefly held against Dean when he was powered by the Mark, blocking two of Dean's blows and even able to counter and simultaneously get a hold on Dean before finally being decisively overpowered while holding back as he had no intention to harm him, to eventually becoming capable of surpassing Sam in skill, as shown when Castiel outfought not only Sam but also several other humans controlled by the psychic Chip. He was able to easily defeat two of them with a single punch, even doing so with a single hand while handling the other using his other hand, and easily break out when one of them got a hold on him, as well as blocking Sam's attacks with minor struggle and knocking him down and Sam only managed to defeat him when Castiel was off-guard, with it being made more notable by the fact that Castiel had no intentions to kill in the fight.
* He later on used hand-to-hand combat to easily smite several zombies unleashed by God before taking Jack's corpse and fleeing, and easily disarmed a Djinn police officer and beat him with a single punch. Castiel was even able to single-handedly escape from the Leviathans that held him captive and only sustain minor injuries in process, a truly impressive feat due to Leviathan being much stronger than Angels and Seraphs.
* **Master Swordsman** - Castiel is highly proficient in swordplay, proving capable of easily killing other angels, demons and later on zombies with a single angel blade. When fighting the Grigori that held Jack captive, Castiel proved able to make short work of his brother with an angel blade despite the Grigori having a superior weapon and having higher strength.
* **Moderate Hunting Skills** - Due to his time spent with the Winchesters, Castiel acquired basic level of hunting knowledge and skill such as using devil's traps to contain demons he captures and on a few occasions, using fake IDs convincingly enough to fool law enforcement in a similar manner to a hunter. However, the latter is a skill that takes him some time to master. Eventually, he became good enough to successfully wield the weapons used by hunters against supernatural creatures with full understanding of their properties, and could also successfully figure out a monster based on their pattern and became an expert marksman of using weapons.
* **Proficient Torturer** – Castiel was shown to be considerably accomplished at the art of torture, as seen when he tortured one of Eve's Jefferson Starships into giving him information in a matter of minutes, despite having his powers blocked by the mother of all and he also successfully tortured Dr. Visyak into giving him the spell to open Purgatory while Crowley couldn't.
* **Leadership Skills** - Although at times insecure, Castiel has displayed himself to be a considerably talented and natural leader, as during his war with Raphael, he was able to lead his angels into holding off Raphael's larger forces, although he himself acknowledged his defeat was inevitable had he not acquired power from the souls of Purgatory, which allowed him to briefly run all of Heaven itself before losing his powers. He later on led a group of angels who pledged themselves to him against Metatron and did so well enough that Metatron chose to turn his angels against him.
* **Strategist** - Castiel has proven himself to be a considerably masterful strategist, despite this not being his strong suit. He managed to use his powers to unscrew a bolt to fall it on Meg so he can use her body to walk out of the Holy Fire that trapped him, defeat all but Zachariah of the angels that guarded Adam by branding an Angel Banishing Sigil in his own chest and was even able to outsmart Crowley and Raphael, Crowley being a cunning strategist in his own right, by giving them false blood while he had the real blood and used it to gain the power of Purgatory's souls.
* **Deception** - Castiel has shown himself to be an excellent liar, being able to fool Dean, Bobby and Sam of his alliance with Crowley for months with them not even realizing it until learning Crowley was still alive.

### Former Powers

After the Fall, Castiel lost all of his powers. Even when he regained his original grace, all of his powers weren't completely restored. Currently, Castiel is not able to use these powers:

* **Apporting** - Castiel could apport humans and other beings when he had his wings.
* **Chronokinesis** – As both a regular angel and a Seraph, Castiel could not only travel through time himself, but was also able to transport people through time and bring them back. However, the further back he sent someone, the harder it was for him to retrieve them. This was evidenced by the time he sent Sam and Dean to the 1800s; he could only send them for 24 hours or else he would be unable to bring them back and they would be lost to him. Upon his being promoted to a Seraph, Castiel's chronokinetic powers were advanced, but he unfortunately lost all of them after the Fall as seen with his stated inability to retrieve Dean from the past in *The Vessel*.
* **Teleportation** - As both a regular angel and a Seraph, Castiel possessed the ability to transport himself and others to any location as long as the area was not protected by enochian sigils, travelling from one place to another instantly. Like with all angels, whenever he used this power, it was accompanied by the sound of wings flapping and a sudden rush of air. He could, however, teleport without these accompaniments when travelling short distances. He was able to take humans with him, though this seemed to have minor adverse effects to the human, as evidenced with Dean stating that he wasn't able to poop for a week after Castiel teleported him. Unfortunately, Castiel lost his teleportation abilities after the Fall.

## Weaknesses

Even though Castiel is arguably the longest lasting angel in the series and is also one of the strongest and most powerful supernatural beings to appear in the series, he still has weaknesses inherited in all angels.

* **Angel banishing sigil** - As an angel and seraph, Castiel can be banished by the sigil. When he was injured and weakened, the angel Ishim convinced Dean not to banish Castiel as it could potentially kill him.
* **Holy Fire** - Like all angels, Castiel can be trapped by holy fire.
* **Angel Blades** - Castiel can and has been killed by angel blades.
	+ **Angel-killing bullets** - These bullets can significantly harm Castiel and potentially kill him.
	+ **Angel-killing saws** - These saws can significantly harm Castiel and potentially kill him.
	+ **Angel Swords** - These swords can significantly harm Castiel and potentially kill him.
* **Herd of Demons** - While an individual demon is no match for him, in Stranger in a Strange Land, over half a dozen of black-eyed demons succeeded to beat up and overcome Castiel, although he stated he is more embarrassed than hurt.
* **Herd of Zombies** - Although Castiel could easily overpower and smite any of the individual zombies unleashed by God, he admitted even alongside Sam and Dean he would be eventually overwhelmed by those zombies and decided to escape rather than continue fighting all of them.
* **Higher Demons** - As a regular angel, he was easily overpowered by Alastair. The demon Ardat proved capable of telekinetically sending Castiel flying and physically injuring and restraining him, although it must be noted Castiel was distracted by her words of Belphegor's true intentions. Belphegor was able to fling Castiel out of Lilith's Chamber when Castiel was not focused on him, although he later on easily overpowered and killed the demon.
	+ **Cain** - Cain mentioned that he could "swat" Castiel like a fly. Indeed, Cain flung Castiel away with telekinesis and merely shrugged off Castiel's angelic white light and it only ruffled his hair but did no damage to the Knight of Hell.
	+ **Princes of Hell** - While fighting Ramiel, Castiel was effortlessly defeated and nearly killed with the Lance of Michael. When fighting Dagon, the latter was able to disarm and beat him with no real effort. At one point, she lifted Castiel into the air with just one hand with him unable to break her hold. Asmodeus was able to throw both Castiel and a weakened Lucifer with a flick of his hand. Asmodeus later tried to kill Castiel and Sam, he would have succeeded had Gabriel not intervened and kill the demon. It should be noted that although Castiel was a seraph when he was confronted by them, his wings were broken.
* **Primordial Entities** - The Darkness, God, and Death could annihilate Castiel effortlessly. Even when powered by all the souls and Leviathans in Purgatory, Castiel remained inferior to God and Death, as Death showed no fear of Castiel and noted he is not God. While weakened by the mass Smiting performed by the Angels, Amara still effortlessly physically overpowered Castiel, throwing him aside, and was able to painfully carve a message into his chest and apport him to Hell with ease. God was capable of suppressing his memories after resurrecting him, although temporarily, and as displayed in the alternate future where Castiel bore the Mark that held God at bay, God was able to influence Castiel into going mad to the point where the Winchesters could not reason with him and had to lock him away with the Ma'lak Box. Billie, with the power of Death, even while weakened and dying from Dean stabbing her with her scythe, was still easily able to overpower Castiel with telekinesis and physically strangle and lift Castiel and would have killed him had Dean not saved him. Acknowledging that they stood no chance of overcoming Billie even in her dying state, Castiel was forced to sacrifice himself by calling upon the Shadow to kill her. An archangel could also easily annihilate Castiel.
* **Higher Angels** - As a regular angel, Castiel was subservient to Zachariah, a higher angel, forcing him to follow his orders, and was overpowered by Uriel once he was demoted while Uriel got promoted. While still a regular angel, he had to follow the commands of his former captains Anna Milton and Ishim. The Grigori Tamiel was able to eventually defeat a wingless Castiel in a fight and likely would have killed him had Claire Novak not killed him while he was caught off-guard. Ishim was also able to easily defeat Castiel, although it must be noted that Castiel was weakened from healing Ishim.
	+ **Archangels** - Archangels could effortlessly overpower and annihilate Castiel with incredible ease. As a regular angel and a seraph, Castiel was absolutely no match for Raphael or Lucifer, having got easily combusted by them instantly. Later on as a Seraph, Castiel was left severely injured by a single blast of light from Raphael. Even while powered by 50 million souls Crowley gave him, Castiel could only temporarily banish him and was later easily overpowered and beat to a bloody pulp by Raphael without effort. Despite killing Raphael in his empowered state of 1 trillion souls from Purgatory, Heaven and Hell, Castiel knew he was still not powerful enough to defeat the oldest and most powerful archangels Michael and Lucifer, resolving to keeping them trapped in the cage. In almost every time he faced off against Lucifer, Castiel was effortlessly defeated and beaten to a bloody pulp, even once when he was aided by Sam and Dean inside the Cage and later on when Lucifer was significantly weakened from his vessel rapidly deteriorating., Lucifer still was able to easily overpower and sent him flying with an uppercut to the jaw with great force and speed. one point, Lucifer knocked him out by simply telekinetically tossing him aside with great ease and he only ever held his own against Lucifer when Lucifer's diminished grace had weakened him greatly and even then, Castiel had to flee and was injured enough by Lucifer that Castiel later passed out. While posing as the Trickster, Gabriel effortlessly overpowered Castiel, telekinetically sent him flying against a wall with extreme ease, and sent him away with no problem and brought him back with a snap of his fingers. The Alternate Michael effortlessly knocked him out with a single punch. In their next meeting, Alternate Michael very easily and soundly beat him to a severe bloody pulp with just a few punches, effortlessly threw him across a room like a rag doll, and drag him with no effort. Although Castiel managed to resist Michael's biokinetic attack when the latter was holding back to relish in his victory, he later on proved to be just as effected as Sam and Dean when Michael took all of their senses and would have been easily killed had Jack not saved them. Upon angering Michael, even with Michael being restrained with advanced Enochian Handcuffs, Castiel was easily overpowered by Michael and slammed on a table with such force it caused Castiel to bleed greatly, and easily stunned and then placed in a chokehold by Michael, being unable to break free until he showed Michael the truth, and backed down when Michael threatened to kill him after Castiel stopped showing him memories, indicating even with Michael's powers weakened by Supernatural Handcuffs, he could still effortlessly kill Castiel.
* **Nephilim** - A Nephilim can grow stronger than an angel. Jane was able to overpower Castiel and Metatron, forcing Castiel to sneak up on her, although it must be noted that Castiel was at a weakened state as the wounds he suffered from being shot by Crowley with angel-killing bullets had not healed. With a small burst of telekinetic energy, Jack easily incapacitated Castiel and the Winchesters to prevent them from stopping him from leaving the Bunker. Later, Jack effortlessly knocked Castiel to the floor, despite barely even touching him, when he tried to stop him from harming someone, while enraged. The effect was enough to keep Castiel incapacitated for a few moments.
* **Eve** - Eve was able to render Castiel completely powerless through her mere presence in a town. Eve told Castiel as she was older, he couldn't do anything.
* **Leviathans** - Leviathans were able to kill Castiel. They could also negate his powers and overpower him. Leviathans were able to take control of and kill him after he absorbed them. Later, the Leviathan leader, Dick Roman was easily able to throw Castiel across a room with great force.
* **The Shadow** - The Shadow was able to beat Castiel down while attempting to get him to sleep. When they met again, Castiel attacked The Shadow who effortlessly knocked Castiel aside. After Castiel intentionally allowed himself to be truly happy by admitting he loves Dean, the Shadow was able to effortlessly take him and Billie to the Empty by impaling them with black tendrils and absorbing them into a portal it had opened.
* **Grace Removal** - When Metatron removed his grace, Castiel gained a soul and became a human, losing all his powers in the process.
* **Mortality (formerly)** – While human, Castiel was susceptible to human mortality and all that came with it.
* **Magic** - Castiel is vulnerable to powerful magic. Rowena could restrain him through a spell and curse him. Rowena even stated that Castiel would have died had she not lifted the spell. Alastair nearly sent him back to Heaven with a expelling spell, and the Whore of Babylon disabled and caused him pain using a enochian spell.
* **Diminishing Grace (formerly)** - Without his original grace and using stolen grace, Castiel weakened periodically and would've died in the end before he regained his original grace.
* **Mark of Cain** - Dean with the Mark was able to physically hurt Castiel with punches and easily overpower him, with Castiel only surviving due to Dean restraining himself.
* **Enochian Brass Knuckles** - Ms. Watt used this weapon against Castiel in order to weaken and overpower him. They are specifically designed to harm angels.
* **Lance of Michael** - A weapon created by Michael to slowly kill Lucifer. It nearly poisoned Castiel to death before being broken by Crowley.
* **Supernatural Handcuffs** - Castiel states that the handcuffs were able to hold him.
* **Gorgon** - Noah Ophis was able to physically overpower Castiel, and his venom was able to paralyze him.
* **Psychics** - The powerful Psychic Chip Harrington was able to telekinetically overpower Castiel.
