Continuity mistake: When the victim falls to the ground in the pre-title sequence his eyes are closed and a pool of blood spills onto the floor from his mouth. When Tony and Ziva are examining the body and taking photo's of the victim, his eyes are now open and the pool of blood is gone from by his mouth. (00:00:50 - 00:03:10)
Visible crew/equipment: When Gibbs and Ziva enter Second Chances to question the owner about Curtis, in the overhead shot Gibbs stops beside the counter, and the red tape mark is visible on the floor between his feet. (00:18:20)
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.
