Continuity mistake: At the end, the way Ziva points to the photo on The Wall changes from one finger to an open hand between shots. (00:37:15)

Continuity mistake: When Jimmy and Ducky are giving a run-down of the suspect to Gibbs, Jimmy puts a Sharpie in his mouth and lowers his hand. When the shot changes, he's got his hand on the Sharpie again. (00:23:50)

Continuity mistake: When McGee tells Tony to stop with the pen, Tony has his thumb up in the rear shot and down in the front shot. (00:04:20)

Continuity mistake: At the start, the phone screen is lit up, receiving a call. However, for one very quick shot, the phone screen is off and not receiving a call. (00:02:00)

Continuity mistake: At the start, the position of the phone on the floor changes between long and close-up shots. Note the floor markings in relation to the phone. (00:02:00)
Continuity mistake: Gibbs gives his report to Vance, who opens the folder, and it's one page. Vance is then holding the folder open, and the camera changes to a second angle where you can't see the folder but can see Vance doesn't move his arm an inch. The camera changes to a third angle, and now the folder is closed. (00:18:20)
Continuity mistake: When Tony is holding out the phone to the ladies walking past him, you can see on the phone's screen Ziva and McGee, who are stood in front of a fixed screen at NCIS. In this shot of them, you can see part of the orange wall of the office. Gibbs then walks in next to McGee. When Tony realises Gibbs is there, the orange section is no longer visible, meaning the camera has changed position. Even if McGee, Gibbs, and Ziva had moved, the orange wall should still be visible since the camera is fixed. (00:16:50)
Continuity mistake: When Tony is on a video call with Ziva and McGee, in the shot of Tony holding out the phone, there is no-one in the pool by the orange towel. When we see the same shot from the video call in NCIS, two people have appeared by the orange towel with no time to move into position. (00:16:30)
Continuity mistake: When Gibbs speaks to the Metro detective, the way the officer next to him holds the sheet of paper on his notepad changes between shots. (00:06:50)

Continuity mistake: They say the suspect was dishonorably discharged in 2008. A minute later in the episode they say he was dishonorably discharged in 2010. (00:10:50 - 00:11:55)
Continuity mistake: 5-4: Identity Crisis. When Ziva is speaking with McGee her lapel changes from being turned up and laying down.
Continuity mistake: When he hands Tony the autopsy report, Ducky has hair falling over his forehead, then combed back, then over his forehead again repeatedly from shot to shot. (00:07:15)
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.
