They follow Alan to a university, where he teaches dentistry classes. There, Alan maniacally instructs all of his students to pull all of the teeth out of all their patients. As he hallucinates and shoots a dental student that he mistakes for Matt, the detectives burst into the room, but Alan uses a hostage to escape. Eventually, he wanders into an auditorium where an opera singer is practicing. Enchanted, he watches her from behind. When he reaches out to touch her, she transforms into Brooke, who laughs at him. Defeated, he falls to his knees and is arrested by the detectives.
