Sam Winchester ( Jared Padalecki ), Dean Winchester ( Jensen Ackles ), and Bobby Singer ( Jim Beaver ) enlist the help of the demon Crowley ( Mark A. Sheppard ) in securing a spell to summon Death ( Julian Richings ) and bind him to their will so that they can use him to stop Castiel. However, Castiel intervenes and breaks the binding spell. Death decides not to punish Sam, Dean, and Bobby for binding him and instead reveals to the group that the entities Castiel is struggling with are the Leviathans, God 's first creations. They had been locked into Purgatory to prevent them from eating the rest of God 's creations. After Castiel finds that he has lost control of himself and slaughtered a group of people under the control of the Leviathans, he goes to Sam, Dean, and Bobby for help, and they help him send all the souls he had consumed back into Purgatory. However, the Leviathans remain in Castiel 's body and assume complete control, revealing that they have killed him from within. Meanwhile, Sam struggles throughout the episode with psychological fall - out of the `` wall '' in his mind that had been protecting him from his memories of torture at the hands of Lucifer and Michael in Hell, having been torn down by Castiel. Sam begins hallucinating and sees Lucifer ( Mark Pellegrino ), who tells him that he was never truly saved from Hell ; what has transpired since the fifth season finale `` Swan Song '' is all an elaborate illusion controlled by Lucifer designed to psychologically torture Sam by giving him false hope before dashing it. 128 `` Hello, Cruel World '' Guy Bee Ben Edlund September 30, 2011 ( 2011 - 09 - 30 ) 3X7053 1.80 The Leviathans realize that they ca n't stay in Castiel 's rapidly destabilizing body and so walk his body into the local water supply and disperse there, possessing civilians who ingest or otherwise come into contact with the water. Seeking a steady food supply of humans, they infiltrate various human establishments. When Bobby responds to a distress - call from Sheriff Jody Mills ( Kim Rhodes ), he discovers that one of these places is Sioux Falls General. Meanwhile, Sam continues to see Lucifer and questions if the world he sees is real or if -- as Lucifer claims -- he is still in Hell. Lucifer urges Sam to kill himself in order to end the illusion, but Dean helps Sam overcome his hallucinations by distinguishing between the pain of real - life and the tortures of Hell. When the brothers return to Bobby 's house, they find it burned to the ground with Bobby conspicuously absent, leading them to fear the worst. The Leviathan Edgar ( Benito Martinez ), having been sent to kill them and Bobby, attacks them and though they manage to temporarily stop him by crushing him under a car, Dean 's leg is broken and Sam does n't respond to Dean 's frantic attempts to wake him up after Edgar knocks him out with a pipe. While being carted off in an ambulance, both brothers receive a shock : Sam is still seeing Lucifer and starts to seize, and Dean learns that the ambulance is taking them to Sioux Falls General Hospital. 129 `` The Girl Next Door '' Jensen Ackles Andrew Dabb & Daniel Loflin October 7, 2011 ( 2011 - 10 - 07 ) 3X7051 1.72 After being sprung from Sioux Falls General Hospital by a perfectly alive Bobby, Dean and Sam join him and lay low for three weeks while Dean 's broken leg heals. In that time, Sam has still suffered hallucinations, but has kept quiet about them. While collecting food, Sam discovers the return of an unknown serial killer and takes off on his own to find her. In truth, the killer is a Kitsune, a monster who removes the pituitary gland in the brain as nourishment. Sam eventually tracks down the monster as an old acquaintance, Amy Pond ( Jewel Staite ), who years ago he had a crush on while hunting Amy 's mother. When Sam confronts Amy on the deaths, she reveals that she has a son who needed fresh meat in order to survive an illness brought on by harvesting dead bodies. As Amy had helped protect and defend Sam, even killing her own mother, Sam lets her go. Dean manages to catch up to Sam and get the truth to his disappearance, and urges Sam to find Amy and kill her. Sam refuses, and acknowledges Dean has been treating him like a hand grenade, and emphasizing that he is managing his hallucinations and atoning for his past actions. Dean agrees to stop badgering him, but later tracks and kills Amy in front of her son because he believes that Amy would have killed more humans in the future. Dean does n't kill the son who has n't killed anyone, but warns that if the son kills anyone, he will. The son promises that the only person he will kill is Dean. Throughout, the Leviathans are shown to maintain an eye on the various rocker aliases of the brothers, using the aliases to catch up to them. 130 `` Defending Your Life '' Robert Singer Adam Glass October 14, 2011 ( 2011 - 10 - 14 ) 3X7054 1.69 While investigating a series of murders in Dearborn, Michigan, Dean and Sam learn that the Egyptian god Osiris is responsible for the killings. A god with nothing but revenge on his mind, Osiris is putting random people on trial for any mistakes they 've made in the past and then promptly killing them if they 're found guilty. Upon sensing Dean 's guilt, Osiris puts him on trial with Sam becoming Dean 's lawyer. But both Sam and Dean are stunned when Osiris calls a witness, someone they thought they 'd never see again : Jo. Jo, however, tries to assure Dean he had nothing to do with her death. Osiris 's second witness is Sam, and he also tries to convince Dean that he had nothing to do with how his life turned out. Sam then calls Dean to the stand, and Osiris then poses a question to him, `` Does he ( Dean ) want Osiris to call the final witness ? Or would he like to hear the verdict ? '' Dean chooses to hear the verdict, which stuns Sam, because he does n't know who the last witness is. Osiris then turns Jo into a vengeful spirit and forces her to try to kill Dean, however, just before she can, Sam stabs Osiris with a ram 's horn, thus saving Dean. The episode ends with Sam telling a quizzical Dean that although he ( Sam ) has done a lot of bad things, he has paid his dues ( with Hell ), hence feels no more guilt. 131 5 `` Shut Up, Dr. Phil '' Phil Sgriccia Brad Buckner & Eugenie Ross - Leming October 21, 2011 ( 2011 - 10 - 21 ) 3X7055 1.92 Sam and Dean find cases of individuals meeting gruesome deaths in Prosperity, Indiana. Several of the crime scenes, however, contain ancient Romanian coins, acting as hexed objects. The brothers learn that each victim was connected to Donald Stark ( James Marsters ), a wealthy businessman, philanthropist and pillar of the community. While Donald assures the brothers that the business deal he and the victims were in had nothing to do with their deaths, Sam searches the house and discovers that Donald 's wife, Maggie ( Charisma Carpenter ), is a powerful witch who is currently separating from Donald. In the process, though, Maggie is killing people connected to ' helping ' Donald set up a fling with one of the victims. Heading to Maggie 's house, Sam and Dean learn that Donald 's personal assistant is next, and manage to save her before Maggie 's curse kills her. Later on, however, it is revealed that Donald himself is a witch, as he uses his powers to destroy Maggie 's auction paintings and decapitate her best friend. When Sam and Dean realize this, they wait for the two to meet at Donald 's house, then try to kill them using a spell with chicken feet. The spell fails, and Sam suggests they counsel the witches on their failing marriage to prevent them from killing Dean and himself. Although they manage to counsel the witches, they are summarily thrown around and beaten for seeming to side with the other party, until Dean is able to say that Donald never tried to have a relationship with his receptionist. The two witches reconcile their love, and Sam and Dean leave with their lives. At the hotel, however, Sam and Dean are confronted by one of the Leviathans, who had been tracking them for days.

Meanwhile, Bobby continues in the course of finding a way to stop the Leviathans, discovers that decapitation works. However, with the head in close proximity, it eventually re-attaches itself to the torso. The brothers eventually find the Leviathans in Iowa but are arrested by local law enforcement. Bobby gets a visit from Sheriff Jody Mills, who offers to clean up the cabin and cook some food for Bobby. While cleaning, however, some soapy water spills onto the Leviathan, causing serious burns. Bobby gives the hostage Leviathan 's severed head to Jody, telling her to dump it. Soon after, Dean, given a phone call, contacts Bobby and manages to learn how to at least stall the Leviathan. The local sheriff eventually helps Sam and Dean when he sees the Leviathan eating one of the officers and turning into Sam and Dean. Sam, in an interrogation room, is confronted by the Leviathan Dean, who reveals Dean 's killing of the kitsune, Amy. Dean and the sheriff manage to decapitate the Sam Leviathan, and then the Dean Leviathan shortly after, keeping the heads with them to prevent re-attachment. Afterward, however, Sam confronts Dean about Amy 's death, telling him he ca n't talk to him right now, leaves Dean and sets forth alone. Meanwhile, one of the Leviathans, disguised as an FBI agent, contacts his superior - a man named Dick Roman - about the recent failure.

Calling in the 1st ranger, he is also taken by the mystery creature ; the creature is eventually shot by Bobby. The hunters soon learn that the monster is actually a vicious, hyperadrenalized human - zombie. As they discover this finding, Dean exhibits similar ' stoned ' symptoms as the forest ranger had. Eventually, Sam and Bobby realize that the cause behind Dean 's mind - dulling ( and that of most of the burger joint patrons ) is the Turducken sandwich, which ends up secreting a grey substance similar to what was within the hyper - zombie. Following the meat to the supplier, the hunters inadvertently discover the base of operations for the Leviathans. It is discovered that the Leviathan were working on a food additive designed to render humans complacent and mindless, potentially for ease of world domination. However, the leader, Dick, appears and closes the project down because the adverse side effects - zombified humans - made headlines, which is something Dick wants to ensure does not happen to keep humans in the dark about their presence. He also dispatches the lead scientist Leviathan, Dr. Gaines, by placing a bib around his neck, and forces Dr. Gaines to eat himself. Bobby, watching everything, is then attacked by another Leviathan and brought to Dick, who reveals that he plans on eating Bobby in the future, but plans to use him to lure in Sam and Dean. The brothers break into the facility and free Bobby, spraying down the Leviathan with Borax to incapacitate and stall them. They then make their escape, with Dick attempting to shoot at the van.

Inside Bobby 's head, he relives one last memory of a night with Sam and Dean as the dream world around him fades away, and the reaper tells him to make a choice : to let his life go, or stay, and become a ghost.

While collecting the slippers, Dean touches the slippers, and begins to be drawn to them, much to his embarrassment ( as the slippers attracted those interested or practiced in ballet ). Before the slippers take their hold, Sam and Dean find the antiques dealer who sold the slippers, and multiple empty curse boxes, as he had sold three other cursed objects. The brothers race to retrieve the cursed objects, although they fail to save one woman, who drinks steaming water from a cursed tea kettle and kills herself. After locking away the cursed objects, the dealer reveals that his mother collected the objects ( presumably being a hunter ), and was recently killed in a car crash after selling her store to a realtor named Joyce, who has recently been buying up several properties in town. Getting the paranoid Frank to dig into the company and its subsidiary, Dean discovers that it is a Leviathan front. Meanwhile, Sam, tired from forced sleep deprivation due to Lucifer haunting him, inadvertently attracts the attention of Joyce 's assistant, George, while getting a coffee. George then follows Sam to the antiques dealer. The Leviathans then set up a trap, forcing the dealer to say he touched a cursed object to lure the brothers to the store. Once there, the monsters attack the brothers. However, George, tired of Joyce 's belittling behavior and reckless impatience, subtly aids Sam and Dean in beheading Joyce, gleefully planning to eat her. Due to their shock, George briefly describes to the brothers that the only real way to kill a Leviathan was to eat them ( or force them to eat themselves, via ' bibbing ' ) and that in this situation, he means them and the people of the town no harm.

Then a hunter ( Garth ) ( DJ Qualls ) is shown getting out of his car. Garth at first believes it 's the ghost of a local legend and torches her bones, however, to his surprise, there is still another dead body reported, hence he decides to call Dean for help. Dean is surprised when he gets a call from Garth asking for the brothers ' help on a case. Sam, Dean and Garth investigate the case, and find out through a translator that the monster is targeting the children of the owners of a local brewery. They find out that the owners had removed one of their partners, who was n't in favor of selling the brewery. This partner, Dale, had literally been the brain behind the company, and loved the company like his own child and upon being removed from his position, had taken his own life. They then find out, that before he died, Dale had harnessed a Shōjō ( 猩猩, a Japanese Sea Spirit ), by placing it in a spell box and sending it as an apology to his old partners, making sure that once the box was open, the Shōjō would kill their children. Eventually, Dean kills the Shōjō, with a blessed ( by a procedure carried out at the back of a restaurant ), samurai blade. Another important story is that of Bobby 's ghost. Bobby has been making his presence felt in the last few episodes, first by dropping the card that led Dean to the hunter who knew Castiel / Emanuel, and from then on helping Dean whenever he gets stuck. For instance, when the Shōjō knocks the blade out of Dean 's hand, it immediately glides back into his hand. Sam tells him it 's just his mind playing tricks on him, as Sam had done a Ouija Board, and had no response. However, Garth, Dean and Sam both find that whenever an EMF meter is put next to Dean, it lights up. Eventually, when they are about to leave the motel they were staying in, Dean goes back to get Bobby 's flask that he left behind. It is then shown that Bobby is present through the flask, but Dean 's inability to see him saddens him greatly. 145 19 `` Of Grave Importance '' Tim Andrew Brad Buckner & Eugenie Ross - Leming April 20, 2012 ( 2012 - 04 - 20 ) 3X7069 1.57 Sam and Dean get a call from Annie Hawkins ( Jamie Luner ), an old hunter friend, asking for help on a case in Bodega Bay, California. When they arrive in town, they find out Annie has disappeared. They trace her last whereabouts to an old abandoned house that is haunted by a powerful ghost. Unknown to them, the ghost of Bobby is following them around, having tied himself to his old flask that they carry. He finds the house populated by mostly mindless ghosts and the spirit of Whitman Van Ness. Bobby discovers the ghost of Annie and the two try to solve the murders. They discover that Van Ness murdered all these people and trapped them in the house, but Bobby gets pulled away when the boys leave before he can learn anything else. Having finally learned how to properly use his ghostly abilities from an arrogant ghost named Haskel Crane, Bobby is able to leave Sam and Dean a message that Annie is trapped and that he is still with them. They return to the house where the ghost of a prostitute named Victoria lets them know about Van Ness before he destroys her. Sam and Dean head off to find and destroy Van Ness ' bones with the ghost following them after he ties himself to an object he places in Sam 's pocket. Bobby and Annie manage to discover the bodies of all the victims and plan to burn them to put the ghosts to rest. However, after Van Ness attacks them, Dean destroys the object and Van Ness returns to his house where he tries to destroy and absorb Bobby. Just in time, Dean burns Van Ness ' bones, destroying him. They return to the house where Bobby is now visible to the Winchesters. Bobby leads them to the remains of Van Ness ' victims, including Annie, and they burn them, putting them all to rest. Dean, however, is furious that Bobby stayed as it 's unnatural and he should 've moved on. Bobby, furious, disappears, but listens invisibly in the boys ' backseat as they discuss the situation, unsure how to handle it and how it will turn out. 146 20 `` The Girl with the Dungeons and Dragons Tattoo '' John MacCarthy Robbie Thompson April 27, 2012 ( 2012 - 04 - 27 ) 3X7070 1.61 Lead Leviathan Dick Roman acquires Frank 's hard drive that contains sensitive information about the Winchesters and gives it to an unsuspecting brilliant hacker named Charlie ( Felicia Day ) telling her that she has 3 days to crack the encryption or she is fired. At the same time, Bobby appears to Sam and Dean and explains the Leviathans ' great plot which he learned before Roman killed him : everything they 're working towards is to turn humanity into the perfect food source for as long as the Leviathans exist. As Charlie hacks the drive, it automatically sends an email to the brothers letting them know what happened and its location from a GPS tracker on it. Charlie successfully hacks the drive, but learns the truth about the Leviathans and Roman from reading Frank 's files on them and then witnessing her boss, Pete ( David Stuart ), get eaten and replaced by a Leviathan. She runs from her job and encounters Sam and Dean who track her down and they team up together to have Charlie infiltrate Dick Roman Enterprises, erase Frank 's drive and hack Dick 's files so they can learn his plans. She succeeds, learning that what Dick had recently been looking for in archeological sites has been found and Sam and Dean retrieve it and replace it with a Borax bomb. Dick realizes her betrayal and attacks her, but Bobby ( who tagged along with her through his flask ) and the boys rescue her, but Bobby attacks Dick and displays signs of becoming a vengeful spirit worrying Sam and Dean as there 's no returning from that. Charlie goes into hiding while Roman worries about the Winchesters figuring out the tablet they stole from him. 147 21 `` Reading is Fundamental '' Ben Edlund Ben Edlund May 4, 2012 ( 2012 - 05 - 04 ) 3X7071 1.66 Sam and Dean break open the clay tablet they stole from Dick Roman causing a storm from which lightning strikes teenager Kevin Tran ( Osric Chau ) and causes Castiel to wake up. Meg calls them and they arrive to find Castiel awake and with his memory intact, but insane. Castiel explains the tablet they found inside the clay is the Word of God, information from God written out on a tablet by Metatron, the celestial scribe, but he lacks the ability to read it. At the same time, Kevin is driven to drive to the hospital where he steals the tablet before Sam catches him while Dean tries and fails to get answers from Castiel. Kevin displays the ability to read the tablet which contains information about the Leviathans, but has a hard time with it and two angels arrive to take him away, explaining that he is a Prophet chosen to interpret the Word and that he needs to be taken away to learn to do that. When they try to kill Sam and Meg, Castiel intervenes, but when they still refuse to stop, Dean banishes all three angels. The group make their way to Rufus ' Cabin where they ward themselves from angels and have Kevin set to work on translating the tablet while Meg sneaks out and kills two demons that followed them. This draws the angels ' attention, but when one tries to kill Castiel, Meg kills her. The other angel allows Kevin to finish the translation before taking him away, but upon his return home, the two angels with him are killed by a Leviathan waiting for him. Sam and Dean discover that the tablet contains instructions on how to kill a Leviathan : `` a bone of a righteous mortal washed in the three bloods of the fallen. '' The first is a fallen angel and Castiel gives them a vial of his blood before disappearing. 148 22 `` There Will Be Blood '' Guy Bee Andrew Dabb & Daniel Loflin May 11, 2012 ( 2012 - 05 - 11 ) 3X7072 1.58 Dick forces Kevin Tran, the prophet chosen to read the Word of God to translate the Word for him by threatening his mother. Bobby reveals to the Winchesters that the blood of the remaining fallen, the Ruler of Fallen Humanity and a Father of Fallen Beasts refers to Crowley and an Alpha. They summon Crowley, but he refuses to give up his blood until they get the other items needed, directing them to the Alpha Vampire who escaped before Castiel could kill him. Along the way, they learn that the domesticating substance has been added to corn syrup and is now everywhere, with people now acting very dumb. Arriving at the location Crowley gave them, they find a bunch of vampires dead from feeding on infected humans and a young woman named Emily who claims that the Alpha kidnapped her as a little girl. With Emily 's help, they locate the Alpha, but leave her and the flask behind at a hotel, as Bobby is showing greater signs of becoming a vengeful spirit. After Emily reveals herself to be loyal to the Alpha and seeing Dick on TV, Bobby possesses a maid and heads off with the flask to get revenge on Dick. Sam and Dean are captured by the Alpha who refuses to cooperate due to a deal with Dick, but when Edgar arrives, he has them locked up to hear what Edgar has to say. Edgar reveals that the Leviathans have betrayed the vampires and are using the fact that they and other monsters feed on the infected humans to wipe out all monsters. He tries to kill the Alpha, but Sam, having broken free, decapitates Edgar. Grateful to Sam and Dean and recognizing they have a common enemy, the Alpha gives them his blood and they leave only to find Bobby gone and realize he 's likely lost to them. Meanwhile, Dick summons Crowley into a Devil 's Trap, telling him they have a lot to talk about. 149 23 `` Survival of the Fittest '' Robert Singer Sera Gamble May 18, 2012 ( 2012 - 05 - 18 ) 3X7073 1.56 Dick speaks to Crowley about a deal : in exchange for giving the Winchesters the wrong blood, Dick will give him and his demons Canada to do whatever they want with as long as they leave America alone. After going through an extensive contract, the deal is struck. At the same time, Sam and Dean break into the crypt of a group of nuns and steal a bone of one they feel is righteous enough for the weapon. Hacking into Sucrocorp 's security cameras using what Charlie taught them, Sam and Dean spy on Dick, but discover that through the arm of the real Dick Roman, he has had many other Leviathans take on his form in order to protect himself and they ca n't tell which is which. Bobby, still possessing the maid arrives to get his revenge on Dick and when Sam tries to stop him, nearly strangles him to death before he regains control of himself and leaves the maid 's body. At the same time, Kevin breaks free and discovers that Dick plans to poison creamers to kill off all skinny people, but is recaptured afterwards. Sam and Dean unsuccessfully summon Crowley while Meg arrives with Castiel who reveals that he discovered that his entire garrison has been destroyed and if any angels have survived, they are in hiding. Crowley arrives and is furious to see Castiel, but after realizing he 's insane, gives them his blood and explains the deal Dick made with him, assuring them that this is really his blood. He also reveals that Cas, who refuses to fight anymore, can help them kill Dick. Castiel refuses to help and after he disappears to get the game Twister, Meg explains that due to him having the Leviathans inside of him, Castiel is able to tell them apart and will be able to identify the real Dick Roman. Bobby returns, but is now having trouble controlling himself and asks Sam and Dean to burn his flask. They do so, promising Bobby that they will finish Dick, but not out of vengeance. Afterwards, Castiel agrees to help and Dean has Meg crash the Impala into Sucrocorp to attract the guards ' attention while he, Sam and Castiel sneak in. Meg decapitates the guards, but is captured by demons working for Crowley. Sam rescues Kevin who explains to him Dick 's plan to kill the skinny people and the two head off to blow up the lab. Dean and Castiel confront Dick in the lab, but when Dean stabs him through the heart with the weapon, it fails to kill him. However, Dean reveals this to be a trick and while Castiel holds Dick in place from behind, stabs Dick through the neck with the weapon, killing him. However, Dean and Castiel disappear and Crowley betrays Sam, taking Kevin and planning to become the next major threat. Crowley also has an army of demons in the building dealing with the remaining Leviathans located there now that Dick is dead. Dean and Castiel find themselves in Purgatory surrounded by monsters and Castiel disappears on Dean. Production The series was renewed for a seventh season on April 26, 2011, and remained on Fridays at 9 : 00 pm ( ET ). The CW announced on August 20, 2011, that the season would be increased to 23 episodes, up one episode from the 22 - episode pickup the series had previously received. On January 11, 2012, it was announced by the executive producer of the show, Robert Singer, that there was another cliffhanger ending planned for season seven. Reception Critical reception to the season has generally been positive. It received a positive review from the review aggregator website Rotten Tomatoes, where it was reported as having a 100 % approval rating with an average rating of 8.8 / 10 based on 5 reviews. However, one criticism from reviewers was of the lack of an emotional link between the Leviathans as a whole and the Winchester brothers, an element which had been present in previous seasons. The lack of threat from the monsters was also noted as a downside to the season, though the portrayal of James Patrick Stuart as Dick Roman, using corporate mannerisms and charm mixed with his own self - confidence, was pointed to as a high point of the story arc. The overturn of Mark Sheppard 's character Crowley at the final moments of the season, was very surprising for the critics. Many argued that Crowley 's successful separation of the Winchester brothers by taking advantage of Dean 's imprisonment in Purgatory and the kidnap of both Kevin and Meg was a good cliffhanger going into the next season, and that it opened up many possibilities and questions. Another well - received point was the return of the Impala at the end of season, much to the appreciation of the fans, and Misha Collins ' portrayal of the resurrected and traumatized Castiel, which brought a new element to the chemistry between the brothers.
