Continuity mistake: When Norman is in Madeleine's shop, he picks up a chocolate chip cookie. We see him bite it, and we get a good look at the cookie. Then he sees Madeleine and begins talking to her. That is not the same cookie he had, because all of a sudden it has a huge chocolate chip near the top now...when it didn't before.
Bates Motel (2013)
1 continuity mistake in The Cord - chronological order
Starring: Vera Farmiga, Freddie Highmore, Max Thieriot, Olivia Cooke, Nicola Peltz
Other mistake: After the scene where Norman texts Bradley that he is coming over, the next shot is Norman looking at the small transcript of his messages to her. If you look, you can see that the transcript starts at 2:34 PM. However, it's nighttime. You can even see the time says 2:34 PM at the top of the phone screen. Also, the original text of 'Hey' is missing although he texted her immediately after receiving it with 'I want to come over and see you.' (00:37:40)
Dylan Massett: You'll do anything to get your way.
Norma Louise Bates: I've never gotten my way, and that includes being your mother.
