Continuity mistake: During the investigation of the dead wife's crime scene, the arms of the corpse change position from shot to shot throughout the scene, including a moment where the corpse's arms are crossed, then in the next shot Ducky is shown crossing her arms. Ducky is also shown crossing the same arm twice, and the guitar control also changes direction and position with respect to the body. (00:03:20 - 00:05:30)Spiritfire
Character mistake: McGee seeks Director Vance's permission to hack into the Sea Hawk's computer system. He says that in the past four months, he hasn't worked any crime scenes, etc. This is incorrect, as near the start of the episode, he and Ziva go to an officer's home to advise his wife that he is missing. They discover her murdered and then the team, including McGee, are working the crime scene.
