Sophia and Thomas are on a private jet. I wonder who's flying it. I also wonder if Sophia, who is currently the subject of a nationwide hunt by the combined might of the entire United States law enforcement and intelligence community, actually went to an airport. Oh, and I guess I go on to wonder where they're going. The show will not bother to explain any of that, because it's apparently more interesting to watch Sophia and Thomas bicker about how Sophia doesn't like Thomas's methods. It's not just the enormous financial empire (which presumably paid for the private jet she's currently enjoying); she's also still mad that Thomas teleported that Avias Air jet out of the sky in full view of everyone. And then threatened to kill the passengers. Thomas defends the teleportation on the grounds that it saved Sophia's life, and the threatened mass murder as the thing that got her out of that Alaskan prison. She says that the detainees could have escaped from Inostranka at any time, but that they stayed so as to protect the ones who were on the outside. Then she tells Thomas that he was afraid of the rain when he was a child (and so much for that bit about them being from a place without water), so she locked him outside during a heavy downpour or something, which made him cry, and from that she concludes that he's stupid and weak. Then they exchange apologies. This whole time, Thomas has been looking twitchy and Sophia has been looking serene, which is the nice way to say "expressionless." I kind of hope he does kill her at this point.

Thomas and Sophia's car (driven by someone) pulls up to a building. They take an elevator down to a mysterious underground concrete bunker. A technical gizmo rises out of the floor, and Thomas enters in a security code. He actually enters it three times, because it's not accepted the first two times he tries. This is how the show intends to convey to us that he's nervous. Then a cube of goo appears, and Sophia reaches inside it to bring out a glowing cylinder. This is the Key Module, which is apparently still viable. If so, it's the first viable thing on the series! Anyway, Sophia turns and sees that Thomas is pointing a gun at her.
