Andy the TSA Sleeper has a big cart full of confiscated stuff, which secretly includes the three virus canisters. He has to get through a locked door guarded by a jolly coworker, but Jolly C. pulls some fuzzy handcuffs out (because "me and the wife like to keep things interesting") and lets him through.
Sophia and Carlos go through the security checkpoint. Sophia is randomly chosen for a hand-scanning. So I may have misunderstood that scene earlier where TSA Andy said he'd get them past security. Maybe he just gave them bogus boarding passes. Oh, hey! You know who should be doing this instead of Sophia? Alex. Remember Alex? The Russian flight attendant? They've already got a sleeper whose job involves the international terminal and they're not using her for this? Sloppy work, aliens. As she's going under the wand, Sophia's phone rings. But she's not allowed to answer it while in the hands of security. We see that it's "Devon." The phone keeps ringing until Sophia has been declared clean. When she answers it, we learn that Devon is the one from the Bureau of Engraving. He says he was stopped, and now it's all up to her. As she listens to the phone, Devon gets shot dead. So the phone connection is still active? The guys who shot Devon could probably justify following up on that without notifying Jarvis right away. But they don't. And now Sophia is sad because she heard Devon die.
It's time for the cabinet meeting. Before they enter, Peel tells Martinez that the food and engraving viruses have been stopped. The entire cabinet rises to applaud Martinez when he enters the room. He looks around slowly and we get a POV shot where it's all tilty and blurry. He falls! Martinez is down! There's no explanation for this, other than the need to have something dramatic happen right before a commercial break. How great would it be if they just completely threw logic out the window now that we're in the series finale? Just have characters gasp, "Oh no!" and throw to commercial, then never mention it again.
Sterling and Simon walk up to Baggage Claim 3, which is where TSA Andy was going to get the canisters through. He told this to Sophia and Carlos, and it was also apparently in the laptop somehow. They go up to Jolly and tell him about the bioweapon and ask if anyone claiming to be a TSA agent has recently rolled a cart of stuff through here. He would like to see some identification before he gives that information out. Well, that's perfectly reasonable. Sterling identifies himself as Blake Sterling, Director of National Security, but Jolly would still like to see a badge. Hey, this isn't strictly relevant to this scene, but it just occurred to me that there was no reason for him to take those fuzzy handcuffs earlier. In his job, shouldn't he have access to real handcuffs? Okay, moving on. Sterling pulls a gun on the guy and demands to know if somebody came through here or not. Jolly admits that TSA Andy did, indeed, go through this door. So that's where Sterling and Simon go.
