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.
Character mistake: As Reddington sets up the blood transfer between himself and Ressler he inserts the intravenous line in Ressler's arm first and then in his own arm. This way the remaining air inside the line gets into the recipient's body and could very well kill him. Judging the expert way he handles the set up he should know to first insert the IV in his own arm, let the line fill with blood and then insert the IV in Ressler's arm.Lenore Scott
Factual error: Tom Keen watches an arms deal. The supposedly German plates of the BMW read "DD17-36F9." This, however, is not a possible combination in Germany, as there would not be numbers in the first half, nor a letter after a number in the second part. [exceptions from the first being the most important officials' cars like the federal president's, but even then the latter applies]. Furthermore, no more than 4 numbers can be used, except for in police and military vehicles (which also never have a letter after a number, and start "Y" for military, or "DD-Q" for Dresden police). "DD-F1736" would have been a correct plate for the town of Dresden, for example. (00:23:15)
Plot hole: At the end of this episode Red takes off his shirt revealing his burned back, which leaves us to think that he might be Elizabeth's dad. However, this particular mark should have been noticed and written down in Red's prisoner file when he was taken into custody the first time (Episode 1). In that case Elizabeth would already know that Red is burned and could have asked some questions about it.
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.bnemirow
Character mistake: When Aram wears the CDC hazmat suit, the CDC personnel advises Aram that he has 20 minutes of air to keep him alive, making the mission time critical. What she says additionally is that "oxygen levels plummet and carbon monoxide (CO) levels rise" CO is not a byproduct of human respiration - carbon dioxide is.
Factual error: Early in the episode, a detective knocks on the door and identifies himself as being from the Metropolitan DC Police Dept., and displays his badge. Apparently the prop department gave the actor the wrong badge, because the one he flashes is from the NYPD, not the DC Police. (00:04:00)Nightguy
Revealing mistake: In the shot of the assassins fleeing the scene of the bullet-ridden Range Rover in Shanghai, China, people are casually crossing the busy street in front of and behind the car. Nobody is looking at what just happened. Computer generated graphics were used to place the car and assassins' motorcycles in the shot. (00:00:50)
