Olivia's getting ready to leave Fitchburg, but not without an eye-rolling lecture from Simone about the mysteries of the universe and how her rational mind can't make sense of her loss and how her heart will find its own way and blah blah blah.
Olivia barely pays attention before acknowledging that Simone has a gift, but adds that it's just an anomaly and not anything that was bestowed upon her. "I know because I'm an anomaly," says Olivia, who proceeds to list all the badass things that she doesn't actually do anymore, like catching bullets in mid-air and lighting things on fire. "I've seen the seams between universes ripped apart, things that humans shouldn't see," she continues, adding that people make up explanations and assigning meaning to things because it's reassuring. Olivia can't do that, though: "I know too much. It's all just numbers. And the invaders, as you call them, they're just better at math than we are," she says.
She thanks Simone, who looks like Olivia just killed her dog, and gets in the truck. Then Simone starts smiling, and Olivia asks why. Yeah, Olivia just destroyed you! How dare you smile! Simone says, "Because I believe. You can't know everything." OK, just drive away, Olivia.
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.
