Continuity mistake: Agent Wells spots Lozano leaving the Pentagon and begins a high speed chase. During that chase Lozano is alternately wearing and not wearing his seat belt. In addition, Lozano's car is only damaged in the close-up scenes; whenever the car is shown from a distance, it is completely undamaged, even after Wells has rammed him repeatedly.
Factual error: At the very beginning of the episode, during Agent Wells' escape in the blue van, there is a very tall skyscraper in one shot. There aren't large skyscrapers like that in DC. Also, when she crashes the van into the Tidal Basin, where did all of the cherry trees that surround it disappear to?
Continuity mistake: When the FBI agent is chasing down "Catalan", after crashing his car, suddenly in one shot the slide of her pistol is retracted, as if the gun is empty. Previous shots it is closed and ready to fire. Then right after showing it retracted and locked back, the very next clip she fires her gun, without doing anything about the slide.
Continuity mistake: When Hannah reads the email about The Traitor she has blood on her face, when she arrests Whitaker she is clean and when she remembers the past she has blood on her face again.
Factual error: FBI Agent Hannah Wells pulls up to the house of the First Lady's mother driving a unmarked police vehicle with government license plates. The license plate is I410918, which is a Department of Interior plated vehicle. The FBI wouldn't be driving a Department of Interior vehicle as the FBI is in the Department of Justice. A Justice plate would have a J and a FBI agent vehicle would have a regular license plate. (00:14:00)
Revealing mistake: When the president talks to the reverend in the Oval Office, the picture of President Lincoln is either higher and then lower when it is shown.
Other mistake: The First Lady mentions that her father's heart transplant was done when she was 10 years old in 2002 which means she was born in 1992, and she was 25 years old in 2017, so when did she give birth to her son Leo who's 17 years old? When she was 8?
Suggested correction: The First Lady never mentioned a date. Andrew Booker's (her father) heart transplant was done in 1987, according to the medical record found. Her father died in 2002, but that wasn't the year of the transplant.
Character mistake: The ‘Brit', Damien from Scotland Yard, and Emily are outside the archive facility - Damien pronounces ‘route' the American way (rowt, rather than root).
Character mistake: President Kirkman calls a soldier a Corporal when she's wearing the rank of Specialist. Next, he calls a soldier Private when he is also wearing the rank of Specialist. (00:04:46)
Continuity mistake: When Tom Kirkman visited the man who killed his wife in prison in S2E10, he sat down for the conversation. In this episode, when the surveillance video of him leaks, it shows him having the conversation whilst standing.
Factual error: The dirty bomb went off at the Brandt Metro station. There is no station with that name.
Character mistake: The chessboard on the desk part way into the episode is set up wrong. Any chess player knows the "white on right" mantra for the white square being in the right corner of the board. In the show the entire board is off and black is in the lower right corner. (00:11:20)
Continuity mistake: When Lorenzo gets in his car after he was in the Pentagon, he has his silver case. When Agent catches up with him, and he gets out of his car, there is no briefcase, even when she looks inside the car. What happened to it?
Other mistake: There is a shot of the NIH building. The lintel says The National Institutes of Health, the correct name. Cut to a shot supposedly inside the building, where a wall hanging says National Institute of Health. So does a brochure given to an actor. (00:17:00)
