Factual error: The Saturn in the show is an Ion which stopped production in March of 2007. Therefore, it couldn't be a silver 2009 Saturn they were looking for.
All the Rage - S6-E1
Continuity mistake: The team is moving into an industrial space where they believe the perpetrator is hiding. There is a generator outside with a red power cord leading under the door they are about to breach. When they burst through the door, the cord is no longer there but it can be seen a few seconds later, but now it is black.
God Complex - S5-E23
Continuity mistake: The chase scene when Maggie, Tiff, and A are chasing the suspect is a total mess. Maggie radios in to say "he ran down the subway", but he doesn't and they pursue him in the streets. Almost immediately, the suspect hijacks a car three blocks away. They locate him in Queens, but now it's night and raining. However, when the chase began, it was bright daylight and clear. Maggie chases him into a crypt, and in the last scene, daylight is shining through a window.
Character mistake: OA says that Vickers went to Erasmus University Amsterdam, but the Erasmus University is in Rotterdam not Amsterdam. (00:07:03)
Visible crew/equipment: When the team of Special Agents are at the auto shop in Red Hook, just as Scola says, "Ethan Chen, you're under arrest," there's a visible pink nylon T-marker on the sidewalk. (00:20:15)
Prodigal Son - S5-E3
Visible crew/equipment: After Agent Hobbs reads the text that Zack sent to Clayton, Jubal tells ADIC Reynolds they need to evacuate Chapman, and in the next shot facing Reynolds there's an orange T-mark taped to the floor behind him. (00:19:35)
Continuity mistake: Early in the show when Vince is driving to the hospital after he is wounded by gunfire, he gets out of the car twice.
Continuity mistake: Early in the episode in the aftermath of the shooting in the pawn shop in which the two glass doors have been shattered and all glass has fallen, there are scenes with large sections of broken glass in the doors.
Continuity mistake: The chase scene toward the end of the episode is a mess. Toward the end of the episode, Scola runs through a door twice while chasing the suspect and, just a few scenes later, Tiff, while chasing another suspect approaches another door twice before she enters.
Continuity mistake: Toward the end of the show Scola and the brother of the principle terrorist emerge from the building containing the now disabled bomb. The brother and Scola exchange a few words and the brother walks away. After a very quick camera change the next shot shows the brother far away from Scola, much too far for him to have walked given the shortcut away.
Plot hole: When Scola and Nina enter the suspect's apartment and begin the search, Nina, before she enters one of the rooms says to Scola " come in here you should see this" indicating that she was aware of something important in a room that she had not yet been in.
Character mistake: The team identifies a blue Lexus fleeing the scene of the murder, but later in the show OA says to Maggie that they've located the black Lexus.
