Continuity mistake: When Agent Wells drives the van filled with bombs out of the parking structure both back doors of the van are open revealing the bombs, in the next shot both doors are closed.
Continuity mistake: Agent Wells is chasing the bad guy on foot. In the first shot her SIG is not cocked. In the next shot it is cocked. In the next shot the slide is retracted. In the next shot she somehow magically fires it. Then the hammer is somehow forward again. A few seconds later as she climbs the stairs it supernaturally transforms into a Glock. And at no time does she use a proper grip on the gun.
Other mistake: When Agent Wells tells the White House they need to alert the Pentagon that Lozano is inside the Pentagon, she is told "it's already done, they are locking down the building right now." Then, later in the same episode, we see Lozano use a key card to easily pass through the building. (00:15:45 - 00:21:15)
The Mission - S1-E5
Continuity mistake: At the end of the episode the undamaged Capitol building is visible in the background, despite being destroyed in the first episode. (00:39:13)
Continuity mistake: Agent Wells is wearing high heel shoes when she gets kidnapped and wakes up on the ship in S1:E19. In S1:E20 she is wearing low heels when she tries to escape on the ship. In S1:E21 she is again wearing high heels when she drives away from the FBI building.
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: Hannah leaves the house in a Ford Fusion. In the next scene she is on the highway in a Toyota Camry. (00:26:50 - 00:27:50)
Continuity mistake: They are taking an oath from the capital building steps that should still be in rubble.
Suggested correction: It's stated that the Capitol is being rebuilt, this is not an error.
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?
Continuity mistake: When Hannah Wells and Jason Atwood confront Brooke Mathison and she tries to fight back with her hidden pistol, Jason fires three shots at her, while Hannah fires two shots at her. However when they show Brooke Mathison again, only one shot is visible on her body. Because she was facing Jason, there should have been at least the three shots he fired at her visible. (00:39:53)
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)
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 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 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.
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?
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.
Party Lines - S1-E16
Continuity mistake: Agent Wells is wearing a green jacket with a black bag. In the next shot, she is wearing an orange jacket with a red bag on her back. (00:36:50)
Continuity mistake: Mike answers the phone with the hoses to breathe and then he doesn't have them anymore. (00:39:45)
Factual error: In the opening scene, Abe Leonard meets with a terrorist leader in what is supposed to be Iraq. However, during their conversation, their breath can be seen, even though Iraq has a hot, dry climate. Even at night, the temperature rarely drops low enough for your breath to condensate, let alone in an urban area during daytime.
