At her apartment, Laura is affected by one last vision of the killer, who has now come for her. The killer attempts to break in through her front door, but Laura deadbolts it before he/she can enter. Upon hearing her distress, Neville (who had been on his way to meet her) breaks through her balcony window. He proceeds to tell Laura they have caught the killer, a troubled colleague of hers named Tommy, and begins an elaborate explanation of Tommy's motivations and back story. Knowing Tommy well, Laura recognizes this as a lie. Neville, still talking about the killer, uses "I". Laura realizes that Neville is talking about himself and that Neville himself is the killer. As Neville details more of his own story, it is implied that he may have multiple personalities. Because of this, and his love for her, he cannot bring himself to murder her and instead asks that she end his life. He takes her hand, pointing the gun at him as she begs him not to and kills him, calling the police as the camera view closes in on her eyes.
