Scisaac

**Scisaac** is the friendship between Scott McCall and Isaac Lahey from the Teen Wolf fandom.

## Canon

Though Scott and Isaac attended the same high school and both played on the lacrosse team, they had little to no interaction before his turn into a werewolf. They were also distant due to Scott being the co-captain of the Lacrosse team and therefore, being part of the popular crowd due to this status. After Isaac became a werewolf, the interactions between Scott and Isaac grew.

In "Chaos Rising," Isaac meets up with Derek in the loft to recover the memories the Alpha Pack had stolen from him during his brief capture. However, they needed Peter's help to perform the memory ritual that Derek did not know of. During their conversation, Isaac points out that Scott wouldn't trust Peter and therefore, Isaac wouldn't either. Instead, he wanted to believe in Scott to do the ritual as well. Derek tells Isaac to trust him at the least, which he reluctantly does. After Peter and Derek failed to access Isaac's memories of where their missing Packmates were, Scott wanted to help his friend remember, so he suggested that his mentor, Deaton could help Isaac. He also stared at Stiles when he spooked Isaac by putting on a rubber glove and slapping it on his skin. This scared Isaac and made him feel more uncomfortable about being submerged in water. Scott even tried keeping Isaac down when he was trying to get out of the water. Unlike Scott, Derek grows frustrated when Isaac doesn't tell them where Boyd and Erica are. However, Derek's shouting method worked and Isaac was able to tell his friends that he remembered where the Alpha's were hiding Boyd and Cora. However, Isaac mentioned seeing Erica's body, much to his horror.

In “Fireflies,” Scott is confident in Isaac’s abilities but he felt that they’re going to need more help than three werewolves chasing Boyd and Erica.

In "Unleashed," Scott gets worried about Isaac during gym glass as they practice for their upcoming track marathon. He sees him running after the twins and tries calling out to Isaac but it's too late. When Isaac confronted the twins, Scott came after. However, they are interrupted when they hear a girl screaming and come to the sight. To Isaac and Scott's horror, another body has been found. After Stilinski comes into the scene, Scott watches as Isaac and Stiles argue about the human sacrifices. He initially took Isaac's side that the Alphas were responsible for the murders taking place because it made no sense. However, Scott was eventually divided on who was right when Stiles pointed out that human sacrifices weren't far-fetched as compared to  Isaac and Scott's werewolf physiology. After Isaac got detention, Scott told him to keep it cool because Aiden and Ethan were just trying to get underneath Isaac's skin. Even though Scott rarely loses his cool, seeing Aiden flirting with his best friend, Lydia Martin made his blood boil. It was the final straw when Scott learned that The Alpha Twins locked Isaac and Allison in the school closet, with Isaac turning into a werewolf and having a panic attack.

After Isaac hurried Allison, Scott saved her and yelled at Isaac to calm down; and like an alpha and beta bond, Isaac summited  Knowing that Isaac wasn't to blame and suffers from claustrophobia due to his abusive father locking him in a freezer,  Scott decided to get even with the Alphas Twins for hurting Isaac and Allison. The tree decided to pull a prank on them and see how they liked it. Remembering that Isaac got detention for "punching" Ethan, Isaac, Scott, and Allison sabotaged their bike and Isaac staged it to look as though Aiden rode his bike through the school hallway in front of Jennifer Blake. Ms. Blake grew angry and gave Aiden detention. As they were leaving the school, Scott and Isaac took pleasure in their revenge against the twins. However, Aiden and Ethan were provoked and proceeded to attack Scott and Isaac until Deucalion intervened and punished Ayden and Ethan by scarred the twins with his cane for both engaging in a pointless prank war with two wolves and probably going after a future, potential ally. Isaac wondered who that was and  Scott figured that must have been Deucalion. At the end of the episode, Isaac comes to Scott's house and asks for a place to stay after Derek throws him out for no explanation. Scott and Melissa welcome Isaac into their home and allow him to stay with them, marking Isaac and Scott as foster brothers.

In time, Scott and Isaac became as close as brothers. Since Isaac's personality often reflected the Alpha, he was with, Isaac learned to adapt to  Scott's no kill rule.
