while the professor takes kami to a hospital and betty goes home, denise stays behind ("if i learned anything from horror movies, it's that the psychotic fictional horror villain never goes for the hot girl in a room that's dark when she's all alone and most vulnerable"). hearing noises coming from her old textbook, denise flips through the pages, and sees herself and the professor having sex in them. denise is transported into the book, and when she and the professor finish fornicating, the professor turns into freddy, and he puts denise into a coma.
