The original ending (which was seen at the 2007 ScreamFest) saw a possessed Katie returning to the bedroom alone, holding a knife and bearing a large circular bloodstain on her chest. She sits down next to the bed on the floor, rocking (movie shorthand for: I have gone nuts). In the background, the answering machine takes a message from a friend asking where they are. The friend then arrives in person, screams when she discovers Micah’s body and leaves. The police are next to show up, ascending the stairs with their guns ready. At this point Katie comes round, confused. But it’s too late: the police shoot her.
A third ending was also filmed. In this version, Micah is dead downstairs. Katie approaches the camera, knife in hand, and slits her own throat
