Silence Lay Steadily

Background

Steven and Hugh find Luke unconscious in the Red Room. Steven, Theo, and Shirley all become locked inside with Luke, and all experience revelatory nightmares about their lives as the house tries to kill them; all the siblings are saved by Nell's ghost. They awaken to find Luke dying. Nell's ghost explains that the Red Room is the "stomach" of the house and can disguise itself as different rooms to each person to calm them while it "digests" them.

It disguised itself as the tree house for Luke, the gaming room for Steven, and so on. The siblings apologize for not saving Nell and she assures them that they all loved each other. Olivia's ghost keeps the siblings trapped, not wanting them to leave. Hugh convinces her to open the door, telling her he will make her a promise.

She frees them, and Shirley and Theo drive Luke to the hospital. Hugh and Steven stay behind and the aftermath of Olivia's death is revealed, including the fact that the Dudleys were Abigail's parents. Hugh says goodbye to Steven, entering the Red Room to stay forever with Olivia and Nell (his promise).
