Everyone scatters except Walter, who keeps examining the dead body. He digs in the wound and pulls out what looks like a quill or a needle or something. "Oh no," he says, and it looks like we're going down the "someone is finishing what Walter started!" route.
Meanwhile, out in the woods, an Animal Control van stops and two guys get out, grumbling about the report of a "monster" that they have to check out. "It's always 'a monster.' 'Monster' must be housewife for 'raccoon,'" says the one guy. Really? Are we supposed to believe that Animal Control gets enough "monster" calls that turn out to be raccoons that this guy needs to be a douchebag about it? Then they hear a rustling and snarling in the bushes. They look kinda scared, but creep forward anyway.
Back at the Fringe lab, Peter comes into Olivia's office to ask if there are any leads on the fourth victim, and she says no, and then stares at him to the extent that Peter asks her what's up, and she says "nothing," but then does a bad job of nonchalantly asking him about calling Rachel, whether it was anything important.
Not only was it not important, but it was annoying as well. Apparently Peter and Rachel were trying to remember the name of the mind-bogglingly irritating "if you like pina coladas" song, like, did either of these two ever hear of Google? More important, did they ever hear of shutting up instead of talking about the pina colada song? And Olivia's all, "So you two are friends now," and Peter smiles at her. "Does that bother you?" he asks. She says no, and he keeps grinning because he knows that it does. The phone rings to break the awkward tension, and Olivia answers: "Hey, Charlie. What's up?"
Walter frantically rifles through his files until he finally finds the one he's looking for, and he looks through. "Oh, good heavens," he says, quietly. Behind him, Olivia comes in to tell Astrid that Charlie got a report from Animal Control about a woman in Newton who nearly hit a "monster" on Route 30, so she's going to meet him there to check it out, and she wants Astrid to call her with any news. As she heads out the door, Walter calls out with a very worried-sounding "be careful," and she pauses, and then thanks him, and then takes off instead of asking him what's up. Peter, though, strolls out of Olivia's office and asks him what that was all about. "Nothing. Just want her to be safe," says Walter, and I guess that's the end of that.
