Dr. Raymond discovers Mary's identity as Lila's daughter and tells Norman that the two of them must be the ones harassing him. He also has the corpse of Norman's mother exhumed, to prove Norman is not being haunted by his mother. Norman is only partially convinced, saying the one behind everything must be his "real mother", despite there being no record of him being adopted. Norman confronts Mary with what Dr. Raymond told him. She says that she has given up her part in Lila's ruse, but Lila will not stop. Later, Norman becomes too terrified to leave his room, saying he saw his real mother in the house. Mary admits to Norman that his sanity is beginning to erode and stays to comfort him.
