Over at the lab, Walter and Astrid are ... running hairdryers over the neck tech? Or something? Walter gets annoyed because Astrid suddenly stops, but it's because she's shocked to suddenly see Peter standing there. As is Walter, when he turns around. "I need you to suture my shoulder, Walter," says Peter. Walter, very concerned, looks at Peter's wounds, like the massive gash on this forehead, and tells Astrid he needs his medical kit, disinfectant and pain medication.

While Walter tends to Peter's owies, he tells Peter about the diagnostic simulation and how the tech is completely reshaping his brain. "The areas that relate to emotion are being commandeered to make room for more logical thought," he says.

Yeah, but Peter's already aware. In a monotone, he starts rattling off everything that's happing: "Shrinking the nucleus accumbens in my limbic system, suppressing emotional memory in favor of higher rational thought, also expanding my cerebral cortex," he says. Walter of all people, says Peter, should know that there's no reason to be afraid of harnessing the untapped potential of the human brain. What? Considering Walter had pieces of his brain removed to LIMIT the potential of his human brain, that sentence makes no sense.

"Are you also aware that the changes will soon be permanent? And if that happens, there's nothing I can do to get you back," says Walter. Wait, aren't you supposed to be accepting the reversibility of all phenomena? At any rate, Peter says he's going to shift Windmark's future so that he passes through the square at exactly 7:19 p.m. "When he does, I will know that he has been reset onto the correct path," he says. Walter says he can't allow Peter to make that mistake, but I'm not aware of any way Walter would be able to stop him. "Don't you see, Walter? When he passes through the square, she will be avenged," says Peter. Walter says they all want Windmark dead, but the way to do it is by watching these fucked-up tapes telling them how to get the equipment they need for a plan that none of them knows how to set in motion. And despite Walter telling Peter that they -- and he -- need him, Peter stands up, all bandaged up, and says he has to go.

Olivia's roaring down a back road in the truck, working on her left-arm tan hanging out the window and cranking up the John Denver. Or else she's all business, talking to Anil on the speaker phone to tell him she's got a truck and a magnet and she needs a place big enough to store them. Anil tells her they've got a warehouse outside the city: "When you're close, I'll have someone meet you and guide you there," he says. Olivia's got to hang up, because up ahead, blocking the road, is an obvious kidnap situation, I mean "car accident."
