Over at Deerfield, Sean's in his room, watching some old black and white movie in which some sort of disaster is causing people to flee in terror from some unseen creature. It's abruptly shut off, and we see that Sean's mother is there. "I told you, Sean, it's too loud," she says. Sean, you may be telepathically linked to a bunch of homicidal genetic freaks, but you mind your mother! She ignores his demand to turn it back on, but then he's distracted as Astrid comes in, because he's just realized he can't hear the voices anymore. And he seems saddened by that, because it's different from when he couldn't hear them before; then, he still felt like they were with him. Not like now: "They're gone. There's nothing anymore, just silence." He asks Astrid why, but she doesn't know, and says they may never know, and she comforts him and this is all wrapping up kid of early, meaning that more shit is going to go down. Mother and child cry, Astrid smiles, all is well. And, um, that's it for the army of two hundred hive-minders? Really? OK...
Peter and Olivia seem to think so. They're pulling up at a gas station and discussing Walter's theory about the telepathic Boys From Brazil just protecting the hive. Olivia's got something else on her mind, which is apparently how once she and Peter were done with a case, they'd go back to one of each other's houses and, you know, get bizzay, like can someone just turn the hose on Olivia already? She's like Pepe LePew after a cat with a stripe of white paint down its back. "So now, I don't know if I'm just supposed to ignore that, or what you want, and I guess I just... Peter, how do you want to play this?"
At least Peter's chuckling now instead of scowling, and when Olivia says she just wants him to think about it, he confesses that he has been thinking about nothing else, but he's afraid because he's made this mistake before. Hey, haven't we all made that mistake before? Cheating on the love of your life with her doppelganger from an alternate universe?
The thing that he's really afraid of, he says, is that when he looks into her eyes, he knows it's her. Well, right. I mean, it is her, isn't it? I mean, this is Peter's timeline, it's just that it was as though he never existed. And so now that he is here, isn't the original timeline just bleeding through? And if he needs to use the machine to pop back into his own timeline, doesn't that make this timeline just revert? And why -- oh, they're making out now, so I guess it's time to shut up.
