In this episode, a mysterious E-mail sent out to all the students except for Alvin becomes yet another worrying issue for our hero, until a little trick played on Henry, the "mentally weak link" of... the class, reveals what his classmates really have in store for him. Relieved and emotionally moved, Alvin allows himself to relax at the pool, where he once again has sex with Rachel, and at Lauren's house, where, much to his surprise, he finds out that his new girlfriend has a thing for bondage... and for screaming out real loud while being pounded, even when her own parents are in the adjacent room!
