Continuity mistake: "Patriot Down": The beach scene in the opening sequence is repeated at the end, but the dialogue differs the second time. Gibbs is kneeling on the sand when someone puts a gun to his head and says, "Welcome to Mexico." When Gibbs reaches for his weapon, the voice growls, "Don't even think about it." These two lines are delivered in reverse order when the scene replays at the end.
NCIS: Naval Criminal Investigative Service (2003)
1 mistake in Patriot Down - chronological order
Starring: David McCallum, Lauren Holly, Mark Harmon, Michael Weatherly, Pauley Perrette
Yankee White - S1-E1
Gibbs: I heard you quit, Agent Todd.
Kate Todd: Happy news travels fast. Yes, I resigned. It was the right thing to do.
Gibbs: Yep. Pull that crap at NCIS, I won't give you a chance to resign.
Kate Todd: Is that a job offer?
Agent Afloat - S6-E2
Trivia: Season 6, "Agent Afloat": Maybe real aircraft carriers posing as fictional ones shouldn't let viewers see their registration numbers. When this episode aired, producers heard from several "carrier purists" complaining that CVN74 is the U.S.S. John C. Stennis, not the (non-existent) Seahawk.
Question: Before she joined NCIS, how long was Kate with the Secret Service?
Chosen answer: It is never stated, however she must have been there several years if she is on presidential detail.
