Anyway, Astrid explains that Walter is giving himself an IQ test, and Olivia says that Falcon's body is being shipped to the lab, so maybe he can have a look when he's done exercising his mind. She gets off the phone and tells Peter that Astrid's having no luck identifying the remaining shapeshifters. "The techs are drawing a blank too. I don't think we're gonna find anything in here that's gonna tell us who Falcon was working with," says Peter. I'd make a comment about how shifty that sounds, but really that's only hindsight because I didn't see it coming at all. But it seems so obvious by this point that I'm embarrassed to have missed it. Olivia grumbles that it feels like every time they learn something new, they're still a step behind: "If we could get to one of these shapeshifters, maybe we could finally get answers."
At the lab, Walter unzips Falcon's bodybag and asks Astrid for a bone saw, aspirator, voltmeter and a ripe banana. Astrid wryly (hopefully?) says she assumes the banana's for Walter. He says he had a sudden craving, which is odd for him, because bananas are usually his least favourite fruit. Anyway, Astrid notes that another twenty names have been cross-checked from Fauxlivia's files -- they're not shapeshifters.
Walter, seeming somewhat embarrassed, asks her if she's read all of Fauxlivia's files. "Most of them," says Astrid, and Walter wonders what Fauxlivia had to say about him. Astrid smiles: "She liked you. She thought that you were kind and brilliant," she says. Not surprisingly, being told someone thinks he's kind and brilliant puts Walter in a cheery mood. As Astrid helps Walter move Falcon into a sitting position, Walter suddenly aggressively opens his mouth wide and bares his teeth, freaking Astrid out just a little. He apologizes, and then realizes what he did: "I was displaying dominance. The serum I took, it must have been meant for a chimpanzee," he says, not exactly making Astrid less concerned about Walter growing chimp DNA in his brain. "Just a bit," says Walter. Oh, well, just a bit. He says his immune system will recognize it as foreign and reject it. Just so long as that happens before he starts flinging feces around the lab.
Anyway, Walter notices something under the fingernails -- blood. Great job missing that, FBI lab techs!
Well, despite Peter's opinion that they weren't going to find anything at Falcon's house, they're still there, looking at a window that was jimmied open, which Olivia says suggests Falcon and his killer were strangers, or otherwise he would've used the front door. Peter offers a noncommittal "hmm" and looks around the room, and now Olivia figures it's as good a time as any to apologize to Peter, who's rather surprised by it. "The last few weeks have been really hard for me. I've been so focused on what the other Olivia did to me that I... I just haven't thought about what she did to you," says Olivia. Well, maybe you shouldn't think too much about everything she did to Peter. She says the good news is Fauxlivia's gone, and they can move past it. Peter smiles and thanks her. Then his phone vibrates, and he says he has to go back to Massive Dynamic for more tests. She offers to drive him, possibly because she wants to have sex with him again, but he says he'll take the train. He does ask her to tell Walter he'll be home late.
