**The relationship between Werecoyote-Werewolf Chimera Theo Raeken and Human Stiles Stilinski**

Theo and Stiles were forth grade classmates until Theo and his family left Beacon Hills after the death of his sister Tara in the early 2000s. In the autumn of 2012, Theo returned to Beacon Hills, claiming that he had heard that Scott McCall had ascended to the rank of True Alpha and he wanted to join the McCall Pack, leading them to believe that he, too, was a recently turned Werewolf. However, Stiles was immediately suspicious of Theo's motives, as he found the fact that Theo returned at the same time that the Dread Doctors started creating Chimeras to be too convenient to be a coincidence.

Theo was dedicated to his portrayal as a well-intentioned Werewolf, and Stiles' investigation into Theo went nowhere. Additionally, the supernatural drama occurring in Beacon Hills forced Stiles and Theo to have to work together, and the numerous good deeds Theo performed, such as saving Lydia Martin's life when she was slashed by Tracy Stewart's Kanima tail and preventing the electromagnetokinetic Chimera Josh Diaz from uncontrollably killing Stiles on the roof of Beacon Hills Memorial Hospital, caused Stiles to begin to let his guard down around Theo, even caring enough to warn him that Lydia and Parrish were searching the woods for the Nemeton, which would inevitably lead them to the bodies of Donovan Donati and Josh Diaz, whom Stiles and Theo killed, respectively.

Unfortunately for Stiles, Theo was soon revealed to be a Werewolf-Werecoyote Chimera and partner of the Dread Doctors who used the secret that Stiles was forced to kill Donovan Donati in self-defense to start breaking the bonds between Scott and Stiles, as well as Scott's bonds with the rest of the pack. Theo's ultimate goal of stealing Scott's Alpha powers (by having Liam Dunbar kill Scott so that Theo could kill him) and then taking the McCall Pack for his own, though this plan was eventually thwarted when Theo, in a fit of impulse, killed Scott himself, preventing him from becoming an Alpha. Stiles was especially horrified when Theo revealed that he wanted Void Stiles in his pack and insinuated that the fact that Stiles had more blood on his hands then any of them made him more like Theo than Stiles wanted to admit.

Despite the disaster Theo wrought on the McCall Pack, they had no choice but to align themselves with Theo and his new pack of Chimeras in order to fight the even greater threat Beacon Hills was facing, the recently-resurrected Beast of Gevaudan, and to save Lydia Martin from her torturous stay at Eichen House. However, this time, Stiles and his pack knew better than to trust Theo, and at the end of the season, they successfully imprisoned Theo in an underground cavern with help from Kira Yukimura and the Skinwalkers.

In Season 6, Theo was released from his prison by Liam Dunbar and Hayden Romero, who sought to use his powers to help fight the Ghost Riders. When Theo asked them where Stiles was, they realized that he, unlike everyone else, still retained his full memory of Stiles. Theo remained a prisoner until he assisted the pack in their fight against the Wild Hunt, thus bringing Stiles back from the Phantom Train Station and possibly hinting at Theo's potential redemption and reconciliation.

Theo continued to assist the pack after Stiles left for his internship with the FBI, but never reconciled on-screen or fought side by side in their final battle against the Anuk-ite and Monroe's Army; however, Scott referred to Theo as one of the pack's (and the town's) protectors, indicating that he had redeemed himself to become a trusted ally of the McCall Pack.

## Throughout *Teen Wolf*

* Season 5A
* Season 5B
* Season 6A

In *Creatures of the Night*, Stiles and Malia were warned by Liam that Scott was in trouble and led them to the tunnel by the entrance to Beacon Hills High School, where Scott and Kira were fighting against a mutated Werewolf named Belasko. Shortly after, Theo, in Werewolf form, jumped into the fray and helped Scott and Kira fight the creature while the others assessed the situation.
Afterward, Theo approached the pack and quickly realized that no one remembered him and remarked that he looked different than he did in the fourth grade. Scott then realized that it was Theo, their old classmate, who had moved away while they were in elementary school, however Stiles continued to eye him suspiciously. Theo explained that he had come back to Beacon Hills with his family and that after he heard that Scott had become a True Alpha, he wanted to come back to his hometown and join their pack.
Theo left soon after, and while the others were heading toward the school for Senior Scribe, Stiles wasted no time voicing his suspicions that Theo had conveniently popped up right when a new shapeshifter arrived in town, but Scott was more concerned about Belasko and how he tried to take Scott's powers.
In *Parasomnia*, Stiles had still not yet dropped his suspicions toward Theo. He woke up early before school to do some research on him at the Beacon County Sheriff's Station with his father, Sheriff Stilinski. Stiles explained that he knew that Theo and his family left Beacon Hills when he was nine or ten years old, and that his older sister Tara Raeken died in an accident when he was eight, but Stilinski, not convinced, simply begged Stiles to go to school.
When Stiles argued that Theo was a Werewolf, Stilinski reminded him that his best friend Scott was a Werewolf, his girlfriend Malia was a Werecoyote, and he was close friends with Kira, whose Kitsune nature he admitted he still did not understand. Stilinski went on to essentially tell Stiles that his suspicions toward Theo were not high on his priority list, and until "flying monkeys come soaring through this station," Stiles should just go to school. When Stilinski refused to do a background check on the Raekens in exchange for Stiles doing what he asked, Stiles reminded him that he wasn't the only law enforcement officer who knew about the supernatural and went to Jordan Parrish for assistance.
Stiles met up at school with Malia, where he explained to her what he found in the background check on Theo's family-- a speeding ticket signed eight years ago by Theo's father. When Malia looked at him in confusion, Stiles exasperatedly argued that people who speed are usually trying to get away from something. This argument was immediately killed when Malia asked him how many speeding tickets he would have if his father hadn't gotten him out of them-- seventeen.
Malia bluntly pointed out that he could understand why Stiles was worried about Theo, as she thought he was really hot with great hair and a perfect body and agreed that he should feel threatened. This did nothing to make Stiles feel better. Seeing that Stiles was genuinely worried, she offered to torture Theo for him, but Stiles preferred to act the way a detective would-- get the story, verify the facts, find the piece that doesn't fit, and catch them in the act. When Malia asked him why he was so suspicious of this new student, Stiles remarked that he remembered Theo from fourth grade, and that this wasn't him.
During second period, Stiles had a free period, along with Scott and Theo, leading Stiles to grab Scott so they could question Theo on what had happened to him since he left Beacon Hills in the locker room. According to Theo, he was skating around in a neighbor's empty pool around a year earlier when he lost track of time and realized it was now nightfall. During his last attempt at a handplant, Theo fell hard, but was confused when he never heard his skateboard fall down with him. When he looked up, a large man with glowing red eyes growled at him, his skateboard in hand, before attacking him and biting him on the right oblique.
Scott had no trouble believing this story and guessed that the Alpha wanted to turn him on purpose, but Stiles immediately questioned Theo on why he wasn't the pack of the Alpha who bit him. Theo answered that by his first full moon, the Alpha was dead, and he learned later from a surviving pack member that the Alpha who turned him was killed by twin Werewolves, implying that it was Ethan and Aiden Steiner's original Alpha. Theo, seeing Scott was the more accepting of the two, urged Scott to listen to his heartbeat to confirm that he wasn't lying, but Stiles snidely pointed out that he could just know how to steady his heart rate while he's "lying his ass off." When Theo asked him why he would want to lie, Stiles suggested that it was because he wasn't who he said he was.
Realizing that Stiles still didn't believe him, Theo brought up another story from when they were children, though he still focused on winning over Scott, since Stiles was clearly still skeptical of him. He reminisced about the fact that Scott had asthma when he was a kid, just like he did himself. He had a bad asthma attack one day in fourth grade, and he was waiting to go to the emergency room when Scott reassured him by telling him everything to expect-- oxygen and IV prednisone. This made the whole situation feel less scary for Theo, like everything would work out okay, and he said it made the process easier. He then changed the subject to the present day, stating that he's been on his own this whole time, and reminded them that they all knew lone Omegas don't make it on their own. Theo went on to swear to both Stiles and Scott that he was the same person they knew in fourth grade, and added that he was hoping they were as well. He then set off for class, joking that they weren't the only people on whom he needed to make a good impression.
After Theo left, Stiles stayed behind with Scott to review what they had just learned, and Stiles was appalled when he realized that Scott believed his story. Scott reminded him that they needed to give people the benefit of the doubt sometimes, but Stiles insisted that this was not one of those times, maintaining that he could feel that something was off about him. Scott joked that Lydia was the psychic, not him, and Stiles snarkily responded that Lydia was actually a Banshee, and there was a difference, but could not dispute Scott's point.
Still not trusting Theo, Stiles broke into the administrative office to get into Theo's file, where he found paperwork signed by Theo's father where his signature didn't match the one on the speeding ticket from eight years earlier. He wasted no time tracking down the rest of the pack in the library, where they were studying for their classes. When he showed them to the others, Malia reluctantly agreed that they were *sort-of* different, causing Stiles to reply, "They're *totally* different! Come on, look. The garlands don't match, the undulations of the sinuous stroke are totally off... and look! Look at this-- perfect example of the criminal tremor."
Confused, Kira asked Stiles if now he thought that Theo was actually Theo, but his parents weren't actually his parents, and Stiles simply stated that *someone* wasn't who they said they were and warned that they would be in trouble when Stiles figured out who it was. Scott reminded Stiles that no one has done anything wrong, but Stiles corrected him by saying "yet" before adding, "If Theo's parents are both psychotic killers, we should not trust him, right?" Malia pointed out that her own parents were the Desert Wolf and Peter Hale, both of whom were mass murderers, which was the final straw for Stiles, who stormed off to figure it out on his own, frustrated by his friends' lack of support in the matter. In Stiles' Jeep, Liam was waiting for Stiles to join him, asking him what a "criminal tremor" was before Stiles drove off.
Stiles and Liam apparently spent hours spying on Theo at his house, watching him play video games, before seeing him set off for the Beacon Hills Preserve. The two then followed him through the woods, thinking they would catch him doing something suspicious. Stiles instructed Liam to use his superhuman senses to get a feel for Theo's emotions, Liam initially complimented his nicely-scented soap before stating that Theo smelled sad, like grief. Stiles became horrified when he realized they had just followed Theo into the woods to pay tribute to his sister, who died under the bridge on which Theo was currently standing and insisted they leave, embarrassed to have been wrong.
Unfortunately for them, Theo had sensed them in the trees behind him and eventually caught up to them to ask them what they were doing. Liam, on edge, growled under his breath defensively, and when Theo remarked to Stiles that Liam was tougher than he looked, Stiles retorted, "Only when we let him off his leash." Knowing that Stiles still didn't trust him, Theo reminded him that they were in Little League baseball together and asked him why he was so suspicious.
Put on the spot, Stiles had no choice but to reveal what he had learned about him today. Theo agreed that the signatures did look different and asked him if he thought his dad was an impostor, Stiles nodded, causing Theo to ask him who he thought he was. When Stiles admitted that he didn't know yet, Theo offered to give him a DNA sample, but he declined due to the fact that he didn't have DNA from years ago to compare it. Theo sighed and explained that though he came back for Scott, he also came back for Stiles, or someone like him-- "Someone who's willing to walk into the woods in the middle of the night to protect his friends." Theo admitted that he didn't have anyone like that in his life, but Scott and the rest of the McCall Pack did, and he wanted to be a part of it.
Now thoroughly embarrassed about being wrong, Stiles and Liam walked back to the Jeep in silence, only to find Scott waiting for them there. When Scott asked them if they found anything, Stiles curtly said "no" before preparing to drive away, causing Scott to correctly guess that Theo went to the bridge in memory of his sister. Unfortunately for Stiles, the Jeep wouldn't start, which prevented him from getting out of this conversation, though he tried to use the fact that he needed to fix the problem as a way to ignore Scott's questions.
Finally, Stiles admitted to following Theo out there and asked Scott what he wanted him to say, as Stiles being totally paranoid was not exactly new information. Scott asked him if he was finally going to at least *try* to give Theo the benefit of the doubt, Stiles argued that he gave a lot of benefit to a lot of people, leading Scott to remind him of other people Stiles initially distrusted who ended up being close friends-- Derek Hale, Kira Yukimura, and Liam Dunbar, to name a few. Stiles, knowing that Scott was right, weakly argued that he *was* right about Peter Hale before shouting at Liam to try to start the engine again. Scott sighed and asked Stiles why he couldn't trust anyone, and Stiles explosively responded, "Because you trust everyone!" before punching the engine, hurting his hand enough that Scott used his powers to take his pain.
That night, Stiles was standing in front of the crime board in his bedroom while he talked with his father. Stilinski, just like Scott, pointed out that they generally wait until a person has committed a crime before declaring them guilty, but Stiles insisted that Theo was guilty of *something*, he just didn't know what yet. Stilinski replied, "Accusations require proof, and proof *always* trumps instinct-- it *has* to," before urging Stiles to let it go and get some sleep. After a moment, Stilinski asked Stiles if he really thought Theo was guilty, and when Stiles assured him that he did, Stilinski stated that all he needed to do then was wait-- those who are really guilty eventually make a mistake that gets them caught.
In *Dreamcatchers*, Stiles continued to not trust Theo, though he was much less outspoken about it due to how many times he was seemingly proven wrong in previous days. However, when a transport van taking Donovan Donati and his lawyer, Mr. Stewart to federal prison was found attacked, with Donovan missing, Mr. Stewart dead, and the driver comatose, Stiles immediately assumed that Theo was somehow involved, even thinking that Donovan may have been referring to him when he talked about his attacked. Despite Stiles' suspicions, Donovan was actually talking about Tracy Stewart, whom they thought was a newly-turned Werewolf who was out of control. Unbeknownst to Stiles, Theo was hiding in the shadows, watching the scene unfold.
Theo eventually caught up with Stiles, Scott, and Alan Deaton at the Beacon Hills Animal Clinic, where they were observing the unconscious Tracy Stewart and had learned that she was actually part-Kanima when she awoke and instinctively paralyzed everyone with her Kanima Venom. When he found them laying on the floor, trying to recover use of their muscles, Theo rushed in and wasted no time helping them to their feet, even the reluctant Stiles who groaned and grimaced the whole time. When Scott explained that they lost Tracy and Malia, who went after her, Theo begged Scott and Stiles to let him help, pointing out that it didn't even have to mean they trusted him or were accepting him into the pack yet-- he could still help them save Tracy.
The four men then went to the Beacon County Sheriff's Station, where Tracy had paralyzed the deputies (including Valerie Clark) and Stilinski himself, severely clawed Lydia's side, and had knocked out Natalie Martin and dragged her down to the basement, where she was subdued by Malia and inadvertently killed by the Dread Doctors, who deemed her a failure. Stiles froze as soon as he saw Kira applying pressure to Lydia's bleeding wound, unable to react until Theo pushed past him, took off his belt, and used it as a tourniquet by applying it around her ribs to stop the bleeding.

## Trivia

* Theo was notable for specifically wanting Stiles and Malia to be in his pack, believing that, since they had both killed before, he had the best chance of tempting them into embracing their darker nature just like him.
	+ For this reason, Theo encouraged Donovan Donati to try to kill Stiles in order to get back at Sheriff Stilinski, knowing that Stiles would likely be forced to kill Donovan in self-defense, which would not only put a wedge between Scott and Stiles, but would also make it that much easier to tempt Stiles into embracing his violent side.
* Theo once told Stiles that he reminded him of his sister, Tara. Whether or not this is a true statement or something he just said to try to win Stiles over remains to be seen.
