Other mistake: The license plate of the car used by Platt (93N-LI62) is the same as the one used by Charlotte Patterson in episode 13 (season 1): The Cyprus Agency. (00:01:10)
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)
Other mistake: The recap of Episode 4.1 has a scene that hasn't been shown until episode 4.2 or 4.3 where the FBI neighbor gets hold of Jennings in his garage to confront him on his alleged affair with his wife. The similar issue with another episode is seen in episode 3.12 or 3.13. (01:00:00)
The Daughter of Autolycus - S4-E5
Other mistake: Lady Felicia says "Ah, Father, how very propitious." The subtitles say "Ah, Father, how very capricious." (00:03:10)
