Continuity mistake: When Gibbs and McGee go to Captain Vetter's home, Gibbs holds up his ID with his left hand in the shot facing Vetter, but the ID is held up in his right hand in the next shot facing Gibbs. (00:17:45)
Visible crew/equipment: While Ducky and Gibbs are at the crime scene in the field, in the long shot just as Ducky says, "He took a tumble down the hill," the raised camera crane, camera, and camera operator (feet are dangling off the front of the crane platform) are visible at the left side of the screen. (00:04:10)
Visible crew/equipment: While Ducky starts to tell Jimmy about an English earl, when Gibbs walks into Autopsy, the reflection of crew members are visible on the steel door's surface. (00:08:35)
Continuity mistake: When Gibbs thumps Tony on the back at the storage locker, his hand is balled up in a fist. In the next shot, Gibbs' hand is extended flat. The pen in Gibbs' hand also disappears. (00:04:45)
Character mistake: In isolation, Tony mentions John Travolta and says that he's known as the "king of cool." That nickname referred to Steve McQueen, not Travolta. (00:15:10)
Character mistake: When Kate mentions James Bond, and DiNozzo lists the actors who have played him, he forgets Timothy Dalton. As a self-proclaimed film buff, that's not a mistake he would make.
Visible crew/equipment: On the rooftop, after Caitlin leaps in front of Gibbs and takes the bullet in her vest, just as Gibbs and Tony help Caitlin stand up, in this shot the blue crash mat is visible on the ground. (00:41:45)
Revealing mistake: When Kate is shot by Ari, Michael Weatherly flinches before the sound of the gunshot, in anticipation of the forthcoming squib explosion. (00:42:20)
