Continuity mistake: When Claire first sees the ghost, Norman rushes in and Claire grabs and hugs him. Her hand was just in the tub yet as she's hugging Norman, her hand is dry. She would have left some kind of a wet mark on Norman's shirt.

Chosen answer: Spencer's theorem was Norman's father's theorem. Norman wants to be greater than his father was, so to be accidentally complemented on something that his father did would be bad enough. To say that the guy knows that his father is dead is to imply that the guy probably insulted him intentionally.
