Surprisingly quickly, Scott's wolf howl attracts the giant alpha, who, having savaged Derek, appears in and around the high-school. There Scott has a hellishly hard time trying to hide or barricade with Stiles and, as a result of phony text messages, Jackson, Lydia and Allison. The alpha's howl and presence cause Jackson's back claw wounds to hurt, which he still hides. the monster kills nobody, but apparently waits until Scott, who believes he's being summoned to the alpha pack like Derek said, transforms and transits by killing his friends. Pressed by the others, Stiles finally calls his father, who arrives when it's all over. Thinking of Allison again allowed Scott to re-assume human form unnoticed, but after the trauma she dumps him till further notice.
