Revealing mistake: At the end when Norman is being stabbed at by Mary dressed up as Mother, Mary stabs Norman in the hand. You can plainly tell that this hand is a doll, as it is not a natural colour, it is stiff and is stationary, unlike Norman who is moving his hands. (01:35:10)
Psycho II (1983)
Plot summary
Directed by: Richard Franklin
Starring: Robert Loggia, Anthony Perkins, Vera Miles, Meg Tilly
Norman Bates (Perkins) has finally been judged mentally sound and released from the mental institution where he has been for 22 years. Once out, he eventually falls in love with Mary (Tilly). But Lila Loomis (Miles), the sister of Marion Crane who was murdered in the shower 22 years before, protests fiercely over his release and wants him put back in the institution for life. Then Norman sees his mother in the window of the Bates house and the murders start happening again. But this time it isn't Norman... or is it?
Mary: You really wanna know what Norman's like?
Warren Toomey: Yeah.
Mary: Better than you'll ever be, fat boy.
Trivia: The reflection of young Norman Bates in the doorknob when he flashes back to his mother's poisoning is Anthony Perkins' son, Oz.

Chosen answer: The murderer is Emma Spool, Norman's biological mother. She was killing people because she didn't want anybody harming Norman.
Emma was not Norman's biological mother. She was the sister of Norma (and Norman's aunt) and jealous that Mr. Bates chose Norma over her and thought Norman should have been the son she and Mr. Bates were suppose to have. Later, while still mentally ill, she believed Norman was her son and told Norman this.

Emma Spool was, in fact, Norman's biological mother. It was revealed at the end of the movie that she is his real mother and Norma Bates is her sister who adopted Norman and raised him While Emma was institutionalized.

Again, that was just Emma being delusional and/or lying. Tracy Venable tells Norman the truth in Psycho III. Emma was never his mother.

I never knew Emma Spool was Norman's biological mother. In fact, I never heard of Emma Spool. Thanks.
