Plot Summary:During Tony's task for the SecNav, Tony took gunfire and sustained a concussion, and he acquired the bloody badge of some other NCIS agent; however, he has no memory of his activities; Gibbs puts him in touch with a shrink. Flashbacks abound, and conversations with the shrink continue; Ducky tells Gibbs about EJ's having removed a microchip from Levin's body. In a flashback, while Gibbs talked with the SecNav, a Navy captain staggered toward the official, and the officer fell dead; the victim had an incision similar to Levin's. In another, Tony found EJ, and they took gunfire but evaded. Slowly, with coaxing, Tony begins to recall; he, EJ, and Cade met in a dark alley, with each believing that one of the other two had sent a summons to the meeting; someone else opened fire. Later the Metro PD found Cade's body along the Potomac River. Gibbs tells Tony the rest of the story, and Tony recalls who the shooter is. EJ remains missing.
