Our new location is a hospital somewhere. Thomas enters a secure room (well, obviously it's not really a secure room, but he had to use a keypad to get in there) and opens a centrifuge. He takes out some vials of blood and replaces them with some other vials. Well, it's a good thing for him that when the nation's top priority is checking someone's blood, they don't bother to post a guard. Thomas walks out and acts suspicious while I wonder why he's doing this himself. Doesn't he have a minion that could be doing this?
When Thomas gets into the elevator to leave, Sterling joins him. They ride down to the ground floor together in a scene that is as boring as it is pointless. The only remotely interesting thing is that we learn that Sterling used to smoke, and Thomas recommends dark chocolate to boost his serotonin.
FOURTEEN YEARS EARLIER, Sterling gets home to find Laura in bed. He asks her if she loves him, and she says she does. He hints around about the subject of spies, but she won't admit anything. Finally, he tells her that he's bought two tickets to Buenos Aires, and that the two of them can leave tonight. He wants to leave with her and disappear. But as soon as he turns his back, she runs. He watches her get into the car, and Pop Sterling jumps out of the bushes and shoots her dead. Pop Sterling tells Regular Sterling to take the gun and pretend he did it. Because that's how you get ahead!
Simon's pal has found the container that brought the isotopes from the armory to the coffee shop. They have two partial prints, which should be enough to identify the mole.
Sean and Leila run through a parking lot and down a street. Leila wants to know where they're going, and I think the correct answer is "Away from those goons with the automatic weapons." She stops running, because she is dumb. Sean tells her he's going to untangle this whole thing so they can get back to living their lives. He insists that they're going to be okay, which I have a hard time believing. A good start would be for them to stop having this conversation out in the middle of a street.
