Continuity mistake: In the first episode, Liz says that the fire happened when she was 14. Later in the series, she states that it happened when she was 4.
Suggested correction: Liz tells the criminal Reddington she got her scar at age 14. She could have been lying. Would you tell a criminal the truth in interrogation? Maybe she was testing his knowledge of when it happened.
Continuity mistake: When Agent Keen first finds Tom's blue key in the base of the lamp she places it on the whiteboard in her op centre, however when she realises that she has to play along with Tom, she is seen putting it back when it was in the base of the lamp. The next time she takes it, it is back on the whiteboard again.
Continuity mistake: The BMW 5 Series equipped with the dirty bomb you see in the beginning of the show is one of the 'F10' type. The car that actually explodes is another car. Possibly an older 5 Series 'E34', but not an 'F10'. Later in the episode you see the F10 again, but when the FBI agent starts the BMW, the interior of an 'E60' BMW 5 Series is shown. (00:00:30)
Mako Tanida - S1-E16
Continuity mistake: After Mako Tanida gets Agent Raim, the camera shows his pant leg with a visible tear in it exactly where Tanida later cuts it with his blade. (00:01:27 - 00:02:15)
Continuity mistake: Agent Keen breaks the train window and dives through the broken glass and cuts her face in two places as she pursues the young man. Her two cuts alternate throughout the following scenes on the train from dripping blood to barely scratches. That evening at home with her husband her face is practically clear and at Reddington's home later that evening her skin is perfect.
Continuity mistake: When Agent Keen attacks Craig in his hotel room he pushes her to a rectangular shaped mirror on the wall but when Red enters the hotel room they zoom in to the same mirror, which is now square.
Continuity mistake: When the plane is about to land the landing gear is deployed. After the abort order, the plane flies low over the landing strip, and the landing gear is up. When it ascends the landing gear is deployed again. (00:34:40)
Continuity mistake: The clock in the hotel initially reads 9:21 and then abruptly changes to 9:20. (00:19:48)
Continuity mistake: When Keen enters Red's Bethesda apartment, the camera pans over pictures on the mantel. Directly left of the picture of a little girl/man on a swing, is a picture of a woman holding hands with 2 children (looks like 1980's, adult woman looks like Keen.) When Keen reaches out to pickup/view the swing picture, the woman/children picture is no longer there and a really old family photo is in its place. (00:21:25)
The Troll Farmer (No. 38) - S3-E1
Continuity mistake: When Solomon forces Isabella to take a photo of her baby and send it to him, the picture she takes is different to the one he receives. Note the position of her baby's hands and stuffed Panda.
Continuity mistake: Rachel the journalist puts on her jeans twice when speaking to Reddington.
Continuity mistake: The knife hole and blood on the envelope of the note to Scottie Hargrave changes. In the first close up, the name is aligned to the middle of the hole and there's a trail of blood running down towards the corner. In Scottie's hand, the hole/blood is higher up and the trail of blood is gone.
Alexander Kirk: Conclusion - S3-E23
Continuity mistake: When Tom Keen returns from shopping to find someone over the cot of baby Agnus, a fight breaks out, during which the camera jumps to different shots of the baby who is wrapped in a pink blanket, then no blanket, then back to wrapped in the blanket. (00:37:22 - 00:37:58)
Continuity mistake: The time on Navabi's phone screen jumps from 6:06 to 6:08 in a matter of seconds when she's talking with Elise.
Continuity mistake: Right at the beginning of the episode a Cadillac Escalade gets stolen. The car is the newest model. The chase begins and the car is a new model right up to a scene when they crash into some other cars. That part was filmed with older model Cadillac. The damage is quite severe, but the chase continues again with the new model that has only one bit of damage - a mirror that has come apart.
Continuity mistake: After the fight at the club, the amount of blood on Liz's chin increases after Emma points it out to her and Liz washes it off in the bathroom.
Continuity mistake: When Emma and Jessica are waiting for the other two, Emma is looking at herself in the broken side mirror, and Jessica is leaning on the hood next to her when the van pulls in. In the next shot, with the van still pulling in, Emma and Jessica are now standing in front of the Cadillac.
Natalie Luca (No. 184) - S4-E12
Continuity mistake: In the scene with Tom, Reddington, Dembe and Agnes; Dembe is playing with Agnes in her cot while Tom and Reddington talk. Dembe later picks up Agnes and puts her on his knee, only for her to return to her cot mere seconds later.
Abraham Stern (No. 100) - S5-E11
Continuity mistake: In the beginning of the episode, Reddington is in a Mercedes S-Class driven by Dembe. This specific car model is mainly used by Reddington in his travels. The car is a 2013 W222 Mercedes S-Class. The interior is also depictive of the specific model W222. Suddenly, he gets into a car accident where the Mercedes he is in is not a W222 but a W221, an older model from 2006 to 2013. (00:00:08 - 01:10:00)
Nicholas T. Moore (No. 110) - S5-E20
