Other mistake: In modern time Natalie Vasquez dies in episode 13 and her character is just discontinued. In flashbacks after that episode she's never seen again. She's not even seen at the graduation day of the trainees, but we see her at the Grand Central bombing, which supposedly happened just days after the trainees became agents.
Factual error: The shoulder patch on the U.S. customs and Border Protection officer's uniform is wrong. The real patch doesn't state Dept of Customs and Border Protection and United States Homeland Security in a smaller circle on the patch. The real patch just states U.S. Customs and Border Protection - U.S. Customs and Border Protection is not a department. Also, the officer doesn't have a name tag on over the right pocket.

Continuity mistake: When Dr. Susan Langdon and Simon are sitting while she eats a hamburger, she doesn't have a gold wedding band on her finger. As the scene continues and she takes a bite, a wedding band appears on her finger. When the scene ends, once again she doesn't have the gold wedding band on her finger. (00:39:00 - 00:42:00)Snag.1
