chunk: At the local courthouse, a psychiatrist explains that Norman murdered Mrs. Bates and her lover 10 years prior out of jealousy. Unable to bear the guilt, he exhumed her corpse and began to treat it as if she were still alive. In order to preserve that illusion, he recreated his mother in his own mind as an alternate personality, often dressing in her clothes and talking to himself in her voice. The "Mother" personality is as jealous and possessive as the real Mrs. Bates had been: Whenever Norman feels attracted to another woman, "Mother" flies into a rage and kills her. As "Mother", Norman had killed two missing girls prior to Marion, as well as Arbogast. The psychiatrist then says the "Mother" personality has taken permanent hold of Norman's mind. While Norman sits in a holding cell, Mrs. Bates' voice is heard protesting that the murders were Norman's doing and that she "wouldn't even harm a fly." Meanwhile, Marion's car is pulled out of the swamp.
