When the staff wake her up, she has a gash in her arm and she somehow has Freddy's hat with her.At home, Marge bars the windows and begins drinking heavily. Eventually, she tells Nancy that Freddy was a child murderer released on a technicality. In a form of vigilante justice, the parents in the neighborhood burned him alive. Realizing that Freddy desires revenge, Nancy convinces Glen to help her. She plans to take Freddy into the real world and set up booby traps in her house. Concerned over her influence, Glen's parents prevent the two from meeting.
