Peyton Sawyer as a Stilinksi AU: Peyton is Stiles’ older sister and all she wants to her dad and brother safe and healthy. At first, she tries to keep Stiles and her dad out of the werewolf drama going as far as to threaten Derek, but when she’s dragged in, she is given no choice but to fight back. When Derek saves Stiles, Peyton realizes that some of the supernatural is good (as well as that her younger brother’s feelings are probably reciprocated). She even forces Stiles and Derek to get their act together and go out.
