FBI: Season 5 (DVD)

Working undercover on a sting operation, OA succeeds in getting close to the buyer, but things take a turn when the buyer's partner is murdered and the bomb they were after has disappeared. Via information from Curt, they learn that the man that stole the bomb is intending to use it at a building where the Federalist Society conference will be held. With still more than 300 people inside the building, OA decides to act against Castille's orders which are to leave the area. He takes an SUV, puts the bomb in it, and manages to get to a safe distance before it denotates. The main suspect flees, taking a young man hostage and the two enter a building with Jubal arriving to lead the hostage negotiations. As Jubal talks to him, Scola and Tiffany use the opportunity to sneak up on him, bringing the crisis to an end. Jubal finds himself struggling to fulfil a promise to attend his son Tyler's birthday party and eventually misses it. Tyler's mother, Sam informs Jubal that four children came to the party, a relief for Jubal as Tyler is going through a tough time as a result of being diagnosed with leukaemia.
