On the waterfront in Washington, DC, two Metro cops find DiNozzo Sr., asleep, amnesic, and hung over at the wheel of a parked rented Rolls-Royce saloon; one of them finds a body inside the boot; the victim, wearing dress blues, was a Naval Reserve lieutenant and aviator but not on active duty; Gibbs and company investigate; at the scene they see who the suspect is, so Gibbs excuses Tony Jr. from the case. While talking in the chat room, Senior tells Gibbs about his relationship with the victim; an officer in the JAG Corps approaches the Gibbs team with useful information; Gibbs, McGee, Ziva, and Abby look under many rocks and talk with many people. Senior mentions a factoid to Gibbs, who offers a bit of advice; Gibbs, Duck, and Abby pursue and persist, then they produce and persuade. Tony, against orders, finds important evidence, then the gang figure out the whole thing and nab the bad guy and a helper. Gibbs, Senior, and Junior prepare for Thanksgiving.
