Factual error: In Oregon and New Jersey, state law requires that a gas station attendant pump the gas. Romero pulls into an Oregon gas station and encounters a nosey person. They are both pumping their own gas.
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)
Factual error: When printing the image of the painting, Stella uses the printer driver "Microsoft XPS Document Writer" - which would save the output to a file. However, she still gets a printout from the printer in the office. (00:02:30)
Suggested correction: Microsoft XPS Document Writer creates a document in XPS format then prints said document. I use it at work. It works in the same way as "print to PDF".
Factual error: The show is supposed to be set in Pennsylvania. But when Roman is getting treatment in a doctor's office, and his phone vibrates on a table next to him, a close up shot of his phone is shown and the cell service is ROGERS. This cell service is only in Canada. (00:22:00)
Factual error: When entering the house looking for his wife, he grabs a guy around the mouth and stuns him with a stun gun. He would have been shocked as well. (00:33:00)
Factual error: The FBI agent introduces himself and says "Mike Weston - I did my thesis on Joe Carol at the academy." FBI agents are required to have a university degree, but they don't write thesis' at the academy. A person is either in a university or at Quantico getting trained. They are not writing papers at Quantico. They need the degree beforehand to get in. (00:10:30 - 00:11:30)
