Meanwhile, Walter's telling Peter that he was right when he said before that he doesn't think of the consequences. "Never have. Don't know if I can. That's not who I am," he says, like how nice to just absolve yourself of any requirement to change by saying, "That's not who I am." Peter says he knows that, but Walter was very brave today. Walter offhandedly accepts the compliment and then heads over to check on Charlie. They watch the ultrasound monitor, and the little larvae are wriggling away. "It didn't 'work," says Astrid, and Walter says, "Ever the pessimist," and they keep watching. Slowly (although much more quickly then you'd think this actually would happen, right?) the larvae stop moving, curl up and shrivel up. "They're dying," says Olivia. Charlie asks what happens now. "Now you crap 'em out," says Walter. Could they have not just tried that in the first place? Given Charlie some Ex-Lax and a bucket? Everybody has a good giggle.
And later, Charlie goes home to his poor wife who has no idea her husband almost died, and she's in bed asleep and he gets in behind her and snuggles in and kisses her. "You feel good," she says. "So do you," he says, already falling asleep.
And Olivia heads back to her own place, where Rachel and Ella are asleep on the couch after reading Burlap Bear again, apparently. Olivia settles into her own bed and turns off the light, and closes her eyes. But the wind howls, and Olivia opens her eyes, turns the light back on, and goes back to sleep. It's worth noting that although we can't actually hear anything other than the wind, after the screen goes to black, the closed captioning says "[creature snarls]." Guess they thought better of throwing that in there.
