Later, Veronica reveals why George and Georgina were allowed to come to the show so late;Their father wants them to learn not to take things for granted(their father is a multi-millionaire). To ' apologize ' for revealing that about the twins, Veronica asks them to pick a contestant, whom she will reveal a secret about. George picks Ripley. Veronica reveals that Ripley's mother is in rehabilitation. This prompts them to remember the story of the woman who got murdered in the house.Ten years ago, that woman finished rehab then came to her home((currently Deprivation House)). Her husband claimed that she was possessed by a demon and then killed her((after she tried to murder her daughter))). Georgina picks Frank. Frank becomes worried that his secret about ATAC will be revealed but Veronica has no idea about that and instead says something about Joe's cover father making fifty times more than Frank's.
Later, the contestants start arguing and accusing each other of being guilty, Brynn and James walk back to the house midway though. After agreeing to meet in the hall later the party heads their separate ways. Frank looks for Brynn and heads to the Deprivation Chamber where he finds a note saying " The House of Death" , eventually finds Brynn in the library, where she has found a picture, with a blond girl and a demon-like creature with giant claws. This causes people to point fingers at Hal, but his drawings are a completely different style. Frank then later sees Olivia and Gail with a sketchbook, which they refuse to let him see.
