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.
