Situation Room again. Thomas is on the phone and says he has the counter-agent, which is what you call an antidote when you want to sound scientific. Martinez tells him not to bother, because he's not releasing anybody. Thomas tells him that the passengers could die, and that he could do the same thing to whole cities. So he's kind of in supervillain mode here. Martinez's counterproposal is that if even one passenger dies, he'll execute Sophia and all the detainees. And now that Martinez is threatening to kill 96 people in cold blood, I feel like he's also a bad guy.

NEW MEXICO, 1945. If flashbacks are in the 1940s, we get a year, but if they're more recent, we just get told it's X YEARS EARLIER. I wonder where the dividing line is. Anyway, Thomas enters a darkened room, in which Simon has been waiting. Have you ever tried sitting in a room with the lights out, waiting for hours until someone comes home? I haven't either, but I bet it's boring. It appears that Thomas has not been staying in contact with the rest of They, since he's been working at Los Alamos, giving the country the ability to generate Nuclear Fission. He claims that the US was decades away from it, but thanks to his work, they're now only months away. This does not match up to the historical record, incidentally. It's almost like none of the people making this show have the slightest idea how this sort of research progressed. But in the world of THE EVENT, I guess we are to ignore the work of people like Oppenheimer and Teller and just assume that a possible alien strolled in and told them how to do it. Thomas's plan is to accelerate scientific progress. And he doesn't care about the A-bomb, either: "It's what we're gonna use it for that matters."

In the present day, Thomas staggers around and the camera gets wacky. I think this is meant to represent his disorientation at his murderous threats being met with someone else's murderous threats. Meanwhile, the Avias 514 passengers and the detainees have four named characters between them, and that's if you count "the Air Marshal from the first episode" as a name.
