Once Thomas and Isabel are out of the room, Sophia tells Simon that Thomas clearly has a secret set of funds. She tells Simon that it's being managed by a banker named Steven Grant, and that Simon needs to go look into it. It's a good thing he doesn't have anything else to do.
Thomas and Isabel are in the parking garage. Thomas knows that Sophia knows about the money, because they did a really, really terrible job of hiding it. He wants to run before Sophia figures out their endgame. They have an endgame? I don't think anyone in this show has the ability to plan things out that far. And I have my doubts about the people creating it, too. Isabel reluctantly agrees that they have to do whatever it is that they were eventually going to do. "You realize how many people will die when we're done?" That's a really vague question. Next they'll be telling us that if Thomas and Isabel do their thing, a mighty empire will fall. That's a Delphic Oracle reference, and it's awesome. Seriously, you should look that up and then be impressed by the Classical reference I just dropped on you.
Back to Sean and Leila. Leila is freaking out about the goon's new old face, saying, "No! No, it can't be!" Which is weird, because she just saw Abby like five minutes earlier. They even talked about how there were injections, and how all the children looked really old. Maybe she forgot. The goon gasps out "Willow Brook Hospital," then he dies. I haven't been keeping track of how many people Sean has killed, but it's got to be at least a few. Even if you don't give him full credit for the explosion in the hacker-dude's lair that one time. Abby's father shows up to tell them not to listen to the goon. And that his family is leaving. Good idea! He recommends that they leave, too. Then he runs back to the gas station. Leila begs him to tell them what he knows, but Sean tells her they're on their own. This is because Sean is used to people not doing what you ask them to do. Although in this case, he's right.
