Audio problem: At the end when DiNozzo is explaining to the marine what happens, the audio doesn't match his mouth. (00:40:00)
Visible crew/equipment: Just near the end, as Ducky faces the other M.E. in Autopsy with his guilt, the camera shows a person reflected in the silver wall (who would be standing beside Ducky). It's not Ducky, as the M.E. is looking at and talking to Ducky with a different angle. The person appears to be dressed in medical scrubs, but the M.E. and Ducky are the only two in the room. (00:40:45)
Character mistake: Dr. Ducky mentions that the inventor of the guillotine in France was Dr. Joseph-Ignace Guillotin, but it was actually Dr. Antoine Louis.

Continuity mistake: When Gibbs and the director sit down for the Chinese food, she picks up her fork and places it into some food. Camera cuts and now she is reaching across the table. (00:32:20)

Visible crew/equipment: When Ziva is with Jason Edom in the interrogation room, Ziva sits down and asks him if he's afraid of germs. Then after Edom's closeup, the red T-mark is visible on the floor near the door in the wide shot. (00:31:55)
