Sophia, as is her wont, is striding around talking to her second-in-command. That used to be Thomas, then Simon, then Michael. Now it's Carlos, which is really scraping the bottom of the barrel. At least the other guys had shown flashes of some sort of personality or history at some point. Carlos seems to have been chosen just because he and Doctor Lu are the only two named aliens they have left. Except for Aaron, I guess, but he seems to be staying in Russia. Which I think is a good call. Stay away from these dopes and their stupid plan. When they moved from Alientown, they didn't just get a new Alientown like any sensible alien invasion with nigh-unlimited funds would have. They appear to have moved into a giant parking garage and are laying out cots. Great. Sophia stops by Doctor Lu's trailer for a status report, and Lu explains that she wants more data on the superflu before she releases it. People on the ship died too quickly to be a good test case. Oh, and she mentions that the aliens are immune to this flu, which is nice for them. Sophia has a plan for another field test. The two of them look at close-ups of dead people on Lu's computer.
Sterling is at home, engaging in his favorite hobby: chain-smoking. A noise makes him reach into a desk drawer for a pistol. Simon strolls into the house, and promptly has a gun pointed at him. Oh, I guess we're supposed to be surprised that it's Simon, because there's a reveal when he turns around. But it was pretty obvious that it was him the whole time. Sterling wants to shoot Simon, but Simon claims he's here to save Martinez's life. He split from Sophia when he realized how many people she was willing to murder. He doesn't bring Sterling up to speed on the killing-billions subplot, but I guess Sophia's killed a few people already.
