You Better Watch Out - S10-E10
Other mistake: McGee's text to Tony says "Dell's body found. Rock Creek Park." The suspect they are looking for and body found is named Justin Cannady. (00:22:23)
Visible crew/equipment: While at Gitmo, Sergeant Spooner is attacked by a detainee, and when Tony joins in the tussle the gun is fired. It then cuts to the tented Global Courier van, and the pink tape mark is visible on the ground behind the van. (00:35:50)
Factual error: There is a flashback scene in this episode, where a young, dejected Abby Sciuto is walking along railroad tracks after failing to give the bear back to Ricki. This scene starts with a shot of the railroad tracks, then pans up to Abby. It can be seen that the rails are laid on concrete sleepers, with modern steel clips holding the rails to the sleepers. Given that the flashback appears to take place when she was at least a couple of decades younger (i.e. the mid-1990s), such modern methods of construction wouldn't have been used. A period-accurate railroad track would have wooden sleepers, spikes and lighter rail. As such, it's obvious that the producers just went to the nearest railroad tracks and filmed the scene there.
Lost at Sea - S10-E4
Character mistake: During the interrogation of Petty Officer Sparks, JAG Officer Lieutenant Nora Patel says "Lieutenant Sparks has a right to legal counsel." (00:21:50)
You Better Watch Out - S10-E10
Continuity mistake: When Tony's dad arrives at the NCIS office for Christmas, he is met at the elevator by Ziva. He is holding a Christmas present (which looks like a bouquet of flowers) with the 'red' end up. As the camera angle changes, he is now holding it 'red' side down. (00:28:25)
Continuity mistake: When DiNozzo is talking about the pictures on the film, he has the film in his hand. But as McGee speaks, Tony has his hand held out and open. (00:02:50)
Continuity mistake: At the start, DiNozzo is holding up his 1974 camera. When the shot changes, the way it's held changes. Take note of his finger in relation to the lens of the camera. (00:02:30)
Lost at Sea - S10-E4
Continuity mistake: When Borin and Dinozzo are talking about why she accepted the date, Borin's hair is constantly switching/moving place. This is not because of the wind. (00:27:00)
Lost at Sea - S10-E4
Continuity mistake: When DiNozzo says about the bet being off, his facial expression changes completely in an instant cut. He goes from concentrating and serious to joking and laughing. (00:27:30)
Lost at Sea - S10-E4
Continuity mistake: The way Gibbs holds the key card that Ducky gives him changes between shots. Watch the sides of the card. (00:09:30)
Continuity mistake: When we see Ducky arriving back at the naval yard, two men walk past his cab but when the shot changes, they walk past again. (00:24:20)
Continuity mistake: When Ziva is on Tony's shoulders, she goes from grimacing and looking at the floor to looking above her and not grimacing as much instantly. (00:04:00)
Character mistake: Ducky states that the Romans believed that the vein of 4th finger on the left hand ran directly to the heart, thus, logically, it was the "ring" finger. However, there is no evidence that the belief originated with the Romans, nor that the 4th finger has a special vein...the fingers in the hand have a similar vein structure.
Continuity mistake: When Gibbs visits Abbie's lab to ask about the smoke detector and computer, he finds the CPU disassembled on her table. The "hard drive" is placed on a white tray in front of the cover, which has been removed from the CPU. Initially, the hard drive is white in color. However, in the close-up shot, it turns black and looks like a different piece altogether. Furthermore, the white tray disappears, and the hard drive sits on the CPU cover. In the wide-shot, the white tray reappears, and the hard drive is again white as it was originally. (00:24:50)
Continuity mistake: When Gibbs comes into Abbie's lab, she hands him a blue Fufu drink, it starts in her left hand, at the cut it jumps to her right hand. (00:07:50)
Chosen answer: It is never stated, however she must have been there several years if she is on presidential detail.
