Isaac Lahey/Relationships

===Scott McCall===
As of 2026, November 2012 was the last time Scott or Isaac ever saw each other again. Isaac currently lives in France with the Argent family and Scott currently lives in San Francisco with Eli Hale and Allison Argent. 
===Derek Hale ===
Isaac was the second beta werewolf created by Derek Hale and the first to join his pack after he was rejected by both his first beta, Jackson Whittemore, and his protege Scott McCall. While Derek was both desperate to build his pack, Derek, in a way, took pity on Isaac, especially because he was constantly abused by his father at home. Derek (who, unbeknownst to anyone, was in a hurry to build a pack to gain power and defend himself against the Alpha Pack, who were about to head to Beacon Hills) was forced to team up with fellow Werewolf Scott McCall and his human best friend Stiles Stilinski to break Isaac out of jail during his first Full Moon as a Werewolf when he was accused of killing Mr. Lahey.
Since Isaac's personality often reflected the Alpha he was with, Isaac became just as ruthless as Derek, intimidating both Scott and Stiles. Isaac initially followed Derek"s every word, showed a willingness to kill Lydia if necessary if she turned out being the Kanima. However, Isaac struggled k to keep up with Derek and began questioning his training methods. As time went on, Isaac started directing his attention to Scott while still remaining at Derek's side. Isaac was also the only one of Derek's Betas who gained control of his temper during the full moon. Unfortunately, after the Kanima's defeat, Isaac went to live with Derek in his loft and help him finding their missing packmates. As the Alphas started targeting Derek's Betas, the older werewolf kicked Isaac out of his loft. After Derek threw a glass at Isaac, the boy quickly left, remembering Mr. Lahey used to abuse him like that.
Even though Isaac was fostered by Melissa and Scott, tension between Isaac and Derek continued as a result of this fight continued to linger for some time. Despite the tension between the two, Isaac and Boyd worked together to protect Derek from the Alpha Pack, but to no avail as it resulted in Boyd's death. However, Isaac had enough of Derek constantly putting himself before everyone and not doing anything to help him and the Pack, other than sit there and watch Cora die. As a result , Isaac joined the McCall pack instead. However, after Derek sacrificed his Alpha Spark to cure Cora, Isaac and Derek repaired their broken friendship until Allison's second death.
The fight against the Oni and the Nogitsune was the last time Derek and Isaac ever met due to the founders sacrifice against the Oni and the Nogitsune nearly thirteen years later. 
===Stiles Stilinski===
Stiles used to hate Isaac, mostly because they were on opposing sides on how to deal with the Karma and the Argents. Not only were they classmates but Stiles and Isaac were both teammates on the Beacon Hill cyclones. After learning Derek bit Isaac and turn him into a beta werewolf and that Isaac was going to be locked in a holding cell on the night of the full moon, Stiles worried about his father and all the other officers at the precinct. However, Stiles did show a sense of urgency and concern that the hunter dressed up as a sheriff's deputy was going to kill Isaac with the wolf's Bane Bullet. 
N season 3, despite no longer being rivals, Stiles grew jealous of Scott and Isaac's relationship, which even grew more concerning when Isaac moved into the Mccall house. Stiles wasn't afraid to hiding his disdain. They often fought our butt heads, much to Scott's frustration. In the fourth episode of Season 3, the boys tried debating about Kyle's true killer. Stiles believed it was a ritual sacrifice while Isaac was convinced that the Twins committed the murder. However, they tried getting Scott to side with them; however, Scott saw both sides of the argument. 
After the Oni killed Allison, Isaac left Beacon Hills for good and it was the last time the two saw each other. Isaac currently lived in France with Argent Relatives and Stiles went on to become an FBI agent in later adulthood.
