In the aftermath of the debacle, Olivia is working her radio trying to find Tyler when Walter comes up and asks, "Where is he?" Olivia doesn't realize at first that he means Peter. That's how on top of things the Feds are today.
Cut to the warehouse, where Beardo is telling her, not for the first time, "We were the hostages in that car." Olivia is doubtful, but Beardo insists Tyler made them do everything we saw them do. And indeed, on second viewing, that mostly holds up pretty well. Even Squinty's gaze, which seemed so squintily malevolent before, can now be read as blankly horrified fascination, knowing what we know now. The episode did a nice job of walking the line there. Olivia is doubtful, until Beardo holds up a bandaged hand and demands, "You think I wanted to saw off my own finger? He made me do it when I tried to get away." As for Peter, Beardo suggests, "You'd better pray he's not with that kid." For all the good that's going to do.
Because Peter is, of course, driving with what appears to still be a hellacious headache. From the shotgun seat, Tyler says this is the result of fighting him. "I can make it stop if you do what I say," he offers. Peter grits out a "yes," and goes limp as though Darth Vader just quit force-choking him. And then he goes right to work on the kid's head, saying, "You know, your father's worried about you." "Awesome," Tyler says drily. Peter starts to pull over so they can talk, but since Tyler doesn't want to, he forces Peter to not only get back on the road but also stamp on the gas, which leads to some very unsafe driving on this narrow two-lane road. They're just about to rear-end a slow-moving truck when Tyler says, "You ready to behave?" Again, Peter says yes, and is allowed to slam on the brakes just in time to avoid an accident. "Just so we're clear," Tyler explains, "I can make you do whatever I want. I can control all of you or just part of you." Peter explains right back, "You know what, kid? You're a real son of a bitch." So at least they've come to an understanding.
That night, Olivia shows Nina a traffic-cam photo of Peter driving Tyler in Walter's car. Nina wonders how this could have happened. "The son of one of your top scientists can control people's minds?" Olivia asks incredulously. "Surely that's not a coincidence." Nina admits that although Tyler's dad works on aerospace projects, he's been working with the pharmaceutical division lately. "What project?" Olivia asks.
