Ethan suspects that the school's hairiest jock, David Stachowski (Jake Epstein) is a werewolf and while trying to prove this fact, he is accidentally hit with a misfired werewolf spell from Benny. Ethan has a vision of David trying to find a cure for himself during the full moon, which confirms his suspicion. However, when Sarah finds out about this cure, she hopes she can use it for herself to become human again. On the night of the full moon, Benny's misfired spell makes Ethan transform into a werewolf. Sarah finds the cure, a drinking potion, and ends up using it all on a werewolf trying to kill Benny, whom she thinks is David. However, when the werewolf is cured, it turns out to be Ethan himself. David isn't a werewolf; he only transforms into a shaggy dog under the full moon.
