Factual error: The episode takes place on the Destroyer DD 964 U.S.S. Paul F. Foster, but every time the ship is shown sailing past the camera you see the number 51 on the side. This is the number of the U.S.S. Arleigh Burke, a DDG not even the same class of ship. (00:11:15)
Visible crew/equipment: When Tony tries to buy the sword for $500 the saleswoman walks away, and as he agrees to $600 in a following shot, the blue T-mark is visible on the floor. (00:23:10)
Continuity mistake: Tony boards a helicopter to go to Puerto Rico. When he lands, it's a different one. The first has the number 406 on its side.
Continuity mistake: When DiNozzo rings Gibbs, we can see Kate taking metal scrapings on a pole that has tape on it just above her hands. When we get a closeup of Kate, the tape is not there. (00:25:50)
Continuity mistake: When the lady at the base exchange is throwing stuff at Tony, Tony has a yellow shirt in his hands that disappears, only to be thrown again. (00:24:00)
Revealing mistake: When the team run from the Captain's office at sunset, Gibbs closes the door as the last man out. However, a shadow can still be seen to move over the door. We know there is no-one else in the office. (00:38:05)
Revealing mistake: Just after Agent Todd is seen going through the diary, there is a shot of the ship sailing past the camera. However the number 51 on the side of the ship is backwards, showing the shot is flipped. (00:30:20)
Answer: I hadn't seen the backdoor pilots yet but while it wasn't explicitly stated, at least onscreen, I heard somewhere Vivian got either fired from NCIS due to jeopardizing a case, got resigned from the agency, or transferred to the FBI.
