Nicholas T. Moore (No. 110) - S5-E20
Continuity mistake: When they are in the hospital, Elizabeth is talking to the young girl and she closes the door behind her. The next time the camera shows Elizabeth's face the room door is open behind her. (00:06:15)
Dr. Laken Perillos (No. 70) - S8-E10
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.
