He also shows him a picture of Tims father who married a new wife and has another son with her, making Tim clear that he has nobody else other than Bob to care for him. Later, he asks him if he also wants a girl showing him the yearbook of a college but Tim refuses, making Bob angry, forcing him later to choose a girl named Angie from it who is also abducted by him.He leaves Tim and Angie in a room, suggesting Tim have sex and then killing her with a knife. Tim hesitates but then stabs her with the knife in the stomach, presumably killing her and burying her body where the others are. ........
