**The relationship between Evolved True Alpha Werewolf Derek Hale and Omega Werewolf Peter Hale**.

Derek and Peter have had a back and forth relationship throughout the years that has gone from being familial to enemies and back again. In their youth, Peter considered Derek to be his favorite nephew and went so far as referring to himself as Derek's "closest confidante" who made it a point to look out for him, though his methods for doing so were questionable, such as his frequent spying on Derek while he was with his high school girlfriend, Paige Krasikeva.

After the Hale House Fire caused by Kate Argent and her many co-conspirators, Derek and his older sister, Laura Hale, the only uninjured survivors, fled to New York to evade the Hunters while Peter was left in a coma in Beacon Hills Memorial Hospital. The two reunited in Season 1 of the series when Derek brought the newly turned Werewolf Scott McCall to visit Peter so that he would know just how dangerous the Argent Family and Hunters in general could be.

However, it wasn't until the end of the season that Derek learned that not only had Peter slowly come out of his coma, but that he had also killed his sister Laura in order to steal her Alpha power so he could fully heal himself of the burns that covered his body from the fire. While Derek was willing to join Peter's pack until he learned the truth about Peter's role in Laura's death; once this occurred, Derek quickly accepted the fact that Peter had to be stopped and ensured that he was the one who would ultimately take Peter's life and Alpha powers, even after promising Scott McCall that he could do so to test out a supposed "cure" to lycanthropy.

In Season 2, Peter, who had used his connection to Lydia Martin (who had been bitten by Peter, triggering her latent Banshee nature) to force her to perform a ritual to resurrect him with a blood sacrifice from Derek and the light of the Worm Moon. After he was reborn, Peter convinced Derek to allow him into his pack, as he needed an Alpha (due to Peter returning to life much weaker than he was when he died and needing the bonds of a pack to regain his strength) and Derek needed a Beta after his former Betas Erica Reyes and Vernon Boyd took off in search of a new pack. After Peter helped Derek figure out how to turn Jackson Whittemore, who was turned into a Kanima after receiving the Bite from Derek, back into the Werewolf he was meant to be, Peter became a member of the Hale Pack.

Peter then became a mentor of sorts to Derek, Scott McCall, and the other members of the Beacon Hills packs, as he knew just as much, if not more, than the other allies and main sources of supernatural information, Alan Deaton and Chris Argent. However, after Peter killed Jennifer Blake, a Darach, on the Nemeton, it became clear that he was just biding his time until he could regain Alpha status and gain more power. He continued to assist the packs in various supernatural issues, such as figuring out how to defeat the Nogitsune and the Oni, why the resurrected Werejaguar Kate Argent de-aged Derek, and who the architect of the Deadpool known as The Benefactor was.

Peter finally saw his opportunity to regain the power he believed he deserved when he teamed up with Kate to turn Scott into a Berserker in order to have someone in the McCall Pack mistakenly kill him in hopes that he would eventually gain Scott's Alpha powers in a convoluted plan that presumably involved killing Liam once Scott had been killed due to the rules of transferring True Alpha powers. When the rest of the McCall Pack and their allies made their way to *La Iglesia* to save Scott and Kira, Derek was stabbed and nearly killed by one of Kate's Berserkers right in front of Peter and the others; whether or not this was part of Peter's plan remains to be seen.

Unfortunately for Peter, upon figuring out Peter's plans, Derek assisted the pack and its allies in neutralizing his uncle with yellow wolfsbane and imprisoning him in the supernatural unit of Eichen House. Derek and Peter were not able to reunite again until the Season 6 finale, *The Wolves of War*, when Derek, who had been traveling in Brazil and the southern United States, returned to his hometown to assist Scott, Peter, and the rest of the McCall Pack in fighting the Anuk-ite and the rabid Hunters who had been corrupted by the fear the Anuk-ite's presence intensified. It was then shown in the flashfowards at the end of the episode that Derek had regained his status as a McCall Pack member and Peter had become a solid ally of the pack as well.

Despite the McCall Pack members being separated for several years due to their respective careers and jobs, both Derek and Peter remained allies of the pack, with Derek raising a son named Eli. When the newly-resurrected Allison Argent wounded and nearly killed Derek with an arrow to his throat, Peter used a blowtorch to cauterize his nephew's wound and stop the bleeding, even replying that he deserved it for slashing his throat fifteen years ago and killing him. Despite this comment, Peter seemed to still care for his nephew and grandnephew to the point that he intended to slit Allison's throat with his claws for her attempts to kill them. Not long afterwards, Derek, Eli and Peter were kidnapped and held hostage by the recently-freed Nogitsune and his Oni. The Dark Kitsune was ultimately incinerated and destroyed by Jordan Parrish, though this act ultimately killed Derek as well because he was restraining the Nogitsune. Peter seemed genuinely devastated and affected by his nephew's loss and he was among those who were present during his memorial service.

 According to Peter, he was once very close to Derek and even went as far as to say that he was Derek's best friend. However, considering Peter was retelling the events of the past from his point of view and was implied to be an unreliable narrator, it's unknown how true the statement was. It is at least revealed that, at best, Peter had mentored Derek, and, at worst, Derek found him annoying and even once threatened to have him banned from school grounds, though it's unknown if this was always the state of their relationship or if Derek was being facetious.

Derek fell in love with a girl called Paige Krasikeva, who was a fellow student at Beacon Hills High School and of whom Peter approved tremendously; while he found the rest of Derek's friends to be annoying teenagers, he believed Paige was perfect for him. Playing on Derek's insecurities, Peter mentioned that Paige would likely break up with him when she found out he was a Werewolf and planted the idea that one of the visiting Alphas seeking counsel from Talia Hale, Derek's mother and Peter's sister, could give Paige "the Bite" and make her one of them so they could always be together.

Out of all of the Alphas attending the summit, Peter had chosen Ennis, who had recently lost one of his Betas to Hunters, to be the one to turn Paige; Ennis agreed to this plan, not only to fill the void with a new Beta but to also "get in good" with Talia, who was a pillar of the Werewolf community. Though Derek initially agreed to this plan due to his fear of losing Paige, he lost his nerve when he heard Ennis attacking her at school and attempted to intervene, but it was no use—Ennis easily overpowered him and pinned him to the floor to show the younger Werewolf that he had already bitten her.

Derek took Paige to the Nemeton's root cellar, where it was revealed that she was dying as a result of her body rejecting the Bite. Shortly afterward, Peter arrived to find Derek cradling the dying Paige in his lap and seemingly became remorseful for his role in what had happened. After Derek was unable to take her pain, Paige begged him to end her suffering, and he mercy-killed her by snapping her spine, causing his gold Beta eyes to turn blue. Peter then took Paige's body and left her in the woods to be found and ruled another one of Beacon Hills' many animal attack victims by the Beacon County Sheriff's Department.

Sometime after this incident, Derek forced himself to attend his basketball game against his family's advice, but had no choice but to hide in the boys locker room when he struggled to control himself during that night's full moon. Peter attempted to teach him the traditional way of the Hale Family by using the Triskelion Medallion and the "Alpha, Beta, Omega" mantra, but it was unsuccessful. From then on, Peter taught Derek his own method of controlling his transformations—to use anger as an anchor and source of power, given him control and strength at the same time.

In *Magic Bullet*, when Scott McCall, who was overwhelmed by fear following his involuntary transformation into a Werewolf by the Alpha and who was unreceptive to Derek's impatient and strict methods of training, admitted that he trusted his girlfriend Allison Argent's family (who were actually Werewolf Hunters) more than he trusted Derek, Derek brought him to the Beacon Hills Home, a long-term care facility where his uncle Peter Hale was a patient.

Scott was shocked when he saw the nearly-catatonic Peter sitting in a chair in his room and asked if Peter was a Werewolf like them, leading Derek to answer in the positive before explaining the story-- six years earlier, while Derek and his sister Laura Hale were at school, their house caught fire, and eleven members of the Hale Family were trapped inside, including Peter, who was the only survivor. Scott, understanding that Derek believed the Argents to be the arsonists, asked why he thought it was them, and Derek angrily retorted that it was because the Argents were the only ones who knew about the family.

Unwilling to believe that the parents of his girlfriend could be capable of such a thing, Scott began to suggest that they must have had a reason before immediately stopping himself, knowing it was the wrong thing to say. Derek aggressively asked Scott what his family could have possibly done to deserve the fact that Peter suffered before pointing out that though the Argents claimed to have a Code that involved only killing adults, and only with absolute proof that they had killed innocent humans, they still set a fire that killed perfectly ordinary, non-Werewolf members of his family. Just then, Peter's nurse, Jennifer, having heard the shouting in the hallway, came into the room to ask them what they were doing and how they got in there, leading Derek to curtly reply that they were just leaving before doing just that.
