Once a Hero - S4-E8
Revealing mistake: When we see Ziva having a close up look at the dead girl, the dead girl's eyes twitch and move slightly. (00:09:20)
Once a Hero - S4-E8
Revealing mistake: When Ducky and Gibbs are in the morgue examining the body of the girl found in the hotel, the camera cuts for a few seconds to the girl lying on the slab. During that shot, you can see her neck moving to her pulse (just after Ducky says, "There's some bruising on the sternum"). (00:19:10)
Once a Hero - S4-E8
Continuity mistake: When DiNozzo is resting at his desk, he has he feet crossed with his left foot on top of his right foot. When the shot changes his right foot is now on top. His hands have also gone from clenched to unclenched in the same shots. (00:20:25)

Once a Hero - S4-E8
Other mistake: When Abby is talking to the microscope guy during the line "you understand without having to go find a dictionary" there is a half second flash of another shot with DiNozzo walking off camera in a street setting. Maybe just a encoding error on Netflix but it persisted after reloading. (00:23:45)
Once a Hero - S4-E8
Audio problem: When the director is working out the letters on The Wall in the video feed her mouth doesn't move for the last L but her voice is heard. (00:38:20)
Continuity mistake: During the scene where Tim and sister Sarah are working on the past evening's timeline, Sarah's clothes lying on the counter change position between the wide shots and the close-ups. Also the plastic her shoes are sitting on in the wide shots disappears in the close-up when she removes them and when she picks up the baggie of money. The screen shot of the locations in the time line also change locations. The 9:30 and 10:00 individual locations show up in the Georgetown University area but when they zoom out to show all three locations, the two time location now show the George Washington University, Foggy Bottom area of D. C., and it shows Tim's residence as being in Arlington National Cemetery. (00:06:35 - 00:07:50)
Visible crew/equipment: When Abby is going through the garbage to disprove Tim's sister you can see a crew member's foot in the screen- it's a brown boot.
Continuity mistake: When the mannequin is hit it's on the double yellow lines with another mannequin stood on the lines behind the first one. When the 4x4 drives off, the second mannequin has moved on its own from the double yellow line to the side with the other 2 upright male mannequins. (00:00:45)
Continuity mistake: At the start, Otto hits the mannequin straight forward. Camera changes and now the mannequin is to the side of the 4x4. After the mannequin is hit, the woman looks out of her side window to look at it. However when we see the 4x4 drive off the mannequin is now on the opposite side. (00:00:50)
Visible crew/equipment: At the start of the sexual harassment class, when Tracy Taylor explains, "A coworker shows you a cartoon or photo of a sexual nature," we can see three orange T-marks taped to the floor near her. (00:02:55)
Visible crew/equipment: When Gibbs is discussing Lt. Seabrook with Dr. Pike, just as Gibbs says, "Gonna need your security tapes and access logs that you keep, Doctor," the cameraman's reflection can be seen moving on the glass surface. (00:10:25)
Chosen answer: It is never stated, however she must have been there several years if she is on presidential detail.
