This episode causes a problem with the timeline of Anthony DiNozzo. In the interrogation scene, DiNozzo states that Tanner tried to put a stop to Honor Corps "twenty years ago" in a flashback we've just seen with Tanner and a young DiNozzo. In the beginning, it's established that DiNozzo was 17 when he came to the academy, but actor Michael Weatherly is actually 47, leaving a 10 year inconsistency. Given the events of the story, the flashback is still quite early in DiNozzo's tenure at the academy, so no additional years could have passed before the final flashback. It is also unlikely that we're to believe the adult DiNozzo is supposed to be 37 given his characterization in the past few seasons, plus the NCIS Wikia (The NCIS Database) gives his year of birth as 1968 (the same as the actor).
