Locked Away • Stalia
Beacon Hills High School has determined that Stiles' disruptive behaviour in class has started to affect his classmates, and teachers, even thought he's really just trying to deal with all the supernatural crap in his life. Unfortunately, that resulted in getting D's on tests, skipping class, being a smart ass, and occasionally punching his best friend in the face. Correction; former best friend.
When Scott figured out that Stiles killed Donavon, and he didn't tell him about it, Scott betrayed Stiles and told the school board that, as a concerned friend, Stiles should get professional help. And out of all the places they could send him, they ship him off to the nut house in which he was almost killed. Twice.
