After the commercial break, Gavin asks again: "Who was your colleague meeting?" No answer from Olivia, and one of Gavin's goons starts getting his gun ready. In the next room, the dingbat FBI agent asks Charlie if they should move in.
Since the cavalry's not forthcoming, Peter jumps to his feet, and all the bad guys start pointing their guns at him, and he says, "That's enough!" and tells Olivia to tell them, because he's not getting "greased over Ernesto's dirty little secret," and Olivia, playing along (I think) tells him to shut his mouth, so Peter says Ernesto is dying, but doesn't want anyone to know.
Despite everything obviously going to hell in the next room, Charlie is still waiting for Olivia to give the signal to move in. Olivia, meanwhile, is pretending to chastise Peter for spilling the beans, and so they argue, and then there's Conrad (presumably) strolling in. Hey, it's Mikey Palmice from The Sopranos! "Gavin! Who are these people?" he says. Gavin says according to them, Ernesto's sick. Olivia says, "It's true. He found out the day before Christmas." Then she and Peter share a meaningful look and might as well have said, "Nudge nudge, wink wink." Conrad says he spoke to Ernesto this morning: "He's fine. Kill them both right now." Gavin steps forward with his gun in Olivia's face, which is when the FBI teams bust in and Olivia and Peter start cracking a couple of skulls while the other agents handcuff everybody.
Conrad's bent over, hands behind his back, and Olivia strolls over to say, "John Scott says hi."
Back at the federal building, Olivia's in Broyles' office. He tells her that Conrad Etienne Moreau is a French citizen wanted in at least half a dozen biological attacks, and those are just the ones they know of. "He's been manufacturing biological weapons and distributing them on the black market for years. And you caught him." By which he means that Olivia might try cracking a smile. Which she does, but then grouches that "I didn't do it alone." Broyles tells her that despite the successful outcome of the case, John Scott's still a traitor as far as the department is concerned, like NICE JOB CHEERING HER UP, BROYLES. "Even if he was telling the truth, there's no way to confirm it," he says. Olivia says she knows the truth, and leaves to go mope somewhere else.
