At the Fringe lab, now, Walter squeezes some gel onto Charlie's stomach to get him ready for the ultrasound, and it's only NOW, after Olivia showed up, and took Charlie down to the lab, that Charlie decides to ask what this is about (but it's OK, because he said, "Enough with the suspense" first, is that it?) and Walter explains that he thinks the stinger that was inside Charlie implanted some embryos. "I think this is why the creature didn't eat you. I think you may be carrying its offspring," he says. Charlie's all, are you telling me I'm PREGNANT? "We're hoping not," says Olivia. Yeah, thanks for that.
So Walter runs the ultrasound wand thingy over Charlie's stomach and looks at the monitor, asking Astrid to go to ten-times magnification, which she does, and sure enough, there are little wormy things crawling around inside Charlie. Walter says, "One small piece of good fortune is the creature doesn't mate in the traditional way," like I'm sure Charlie feels better about the larvae inside him since he wasn't RAPED BY THE EAGLE REPTILE, and Peter gives Walter crap for his "great bedside manner." Olivia asks what they do now, and Walter says he doesn't know, because they've already spread throughout his system. He looks really down, and walks away. Peter follows him and quietly tells his dad to calm down.
Charlie, meanwhile, asks Olivia how these things were actually born in the other victim. Olivia smiles and says, "It doesn't matter, because, um, it's not going to go that far." Which I'm sure Charlie is smart enough to translate as, "If it goes that far, you're going to be in a world of pain that will make you crave the sweet release of death, which will actually be coming pretty quickly itself."
Peter's telling his dad that there has to be something he can do, but Walter looks awfully despondent. "You can't check out right now. We cannot let this man die!" His dad snaps that he knows that, loudly enough that Astrid, Olivia and Charlie look over to see what the commotion is. Walter says he's thinking, and then he looks over at a beaker with a couple dozen writhing larvae. He tells Astrid to draw 25 milliliters of blood, and tells Peter to get some trichlorimide; he's going to try poisoning them.
Astrid warns Charlie that the needle is going to pinch a little bit, and Charlie grimaces, like you'd think it would take a lot more than this to cause him pain, considering what he's just been through. While Peter and Walter prepare the poison, Charlie asks how much time he has if this doesn't work. Olivia says, "The last victim, we figured 24 hours after he was..." "...knocked up," finishes Charlie. Olivia says yes. "So I have about 16 hours," says Charlie. Well, I have an idea! Someone pull up a television and a couple seasons of Arrested Development, and the time will fly by!
