As they walk into another room they pass by a coffin with a hand sticking out. They come across a stash of odd items including an M-16, top hat, and toy statue. They hear some chanting and go to a window to see Hank at a podium and a group of women, including Eve Parson, chanting and dancing around a cauldron. Josh goes to get the tires while Greg stays and watches the seance. As Josh is rolling the tires, he finds the casket with the arm hanging out and when he opens it, finds Mrs. Andrews in a wedding dress. The door to the room Greg is in shuts and is locked.

At night, Christie has a nightmare and starts to sleepwalk. She walks over to the window overlooking the pool as the person wearing the robe looks at her through another window. She goes outside and walks into the pool. She wakes up as her mouth hits the water and the person in the robe calls out to her. She runs inside and calls out to Eve and tells her someone tried to kill her. Eve tells Christie she wants to take her to see a psychologist, but Christie accuses Eve of wanting to get rid of her.

As Greg is leaving, he is pulled into the embalming room by Paul. Paul tells him Sheriff Duncan was at the mortuary asking questions about Greg and Josh once told him he wanted to run away and join the Navy.
