Both Gibbs and Fornell answer a call for help from Diane, their mutual ex-wife; her current husband, Victor (an employee of the US Department of Homeland Security), has disappeared; Tony reports a hit on Victor's credit card at a burger joint the night before, then McGee reports a recent 911 call about a bloodbath at the same place; the gang investigate. Tony and Ziva say that Victor appears to be a suspect rather than a victim; Abby and a friend announce what Victor stole; McGee finds more secrets; Gibbs, Fornell, and Tony find Victor, who expresses relief and reveals the intent of the bad guys. The team plus Fornell go to a football stadium just before a major game; they find the bad guys, and they deal with them. Fornell tells Vance the motive for the criminal activity. Later Diane approaches Gibbs in his basement, and they have a concluding chat, during which she hands him a watch.
