Over the next few days, Rebecca and Tyler notice their grandparents exhibiting more strange behavior. When Rebecca asks Doris about what happened the day Paula left home, Doris begins shaking and screaming until Rebecca calms her. John and Doris are later confronted by a woman who was helped by them in counseling; she goes into the house with them but is never seen leaving. Tyler, concerned about the occurrences, decides to secretly film what happens downstairs at night. Doris discovers the hidden camera, retrieves a large knife, and unsuccessfully tries to break into the children's locked bedroom.
