Mary is startled later when she discovers someone looking at her through a peephole in the bathroom wall. She calls out to Norman, who is downstairs and out of reach. The two are horrified to find a bloody cloth that has been stuffed down the toilet. Norman appears confused and believes he may have committed another murder. Mary goes down to check the motel. In the parlor she is surprised by Lila, who reveals herself to be Mary's mother. She has been calling Norman claiming to be his mother, even going so far as to dress up as her and allowing him to see her in the window. Mary has been helping her. She was responsible for restoring Mother's room at the house and locking Norman in the attic. All of this was an attempt to drive Norman insane again and have him recommitted.
