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: 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)
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 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: At the start, Reddington and Dembe are talking to a garageman. He has a protective helmet on him. They zoom in and out of him, and show him from side and front. The strap on his helmet is different every time. One time it's over his ears, one time fully above it, and the next is sits low on his ear. All this within a short minute-long talk.
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.
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.
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)
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.
