Sean breaks into a house by taking out the window screen. Then he eats an apple and some chicken. A blonde interrups him with a bat. He calls her "Sis," and because I am a kind and generous person, I will not go back to look at those dossiers of Sean and Leila to see if he had a sister back then. Sean explains that he didn't think she'd be home.
Sean's sister gives him a sandwich and tells him that the police have been by, looking for him because they say he killed someone on a cruise ship. He says he was framed. "By who?" she asks. That's his excuse to talk about the attempted presidential assassination and the experiments on little girls. She asks, "Did you go to the police?" "You don't believe me. Why would they?" Well, for one thing, there's that FBI agent who can back up most of what you've said. For another, you know perfectly well they've found that plane by now, and that they know about the attempted assassination. In fact, Michael just escaped from prison. So Sean can probably assume that there are people in the law-enforcement chain that know he didn't kill that dude on the cruise ship. But he's refusing to even check in with them and clear his name. Nice. From now on, all your problems are your own fault, dummy. He also doesn't want to talk about Leila. He's not staying. He just wants to know if Jimmy (an offscreen person that his sister knows) knows people who can hook him up with a fake ID so he can run to Mexico. Liz is outraged that he's just running away. "Don't you wanna stop them?" It would be nice to think that his face adopts an expression of grim resolve, so let's pretend that's what happens.
Sterling extrapolates from Chernobyl that an explosion at San Onofre would devastate most of Southern California. They have a plan for moving the rods. And the general has a magnetic device in Camp Pendleton, so the plan is to extract the uranium and take it over there. Martinez wants to consider attaching a tracking device to the rods and just letting Thomas take them. Well, that would allow a meltdown. Martinez wants to know if there's any reason to believe Sophia, and Sterling tells his story about Maya, the moral of which is that Sterling believes that Sophia and Thomas represent different segments of the aliens. Martinez says to move the rods.
