Broyles shows them the picture of the kid, and then Walter excitedly says he saw a kid like this once, who played the banjo, and then he sings "Dueling Banjos" and is surprised when Peter does it too, and Peter has to break it to him that Deliverance was just a movie. "Probably not the same boy," acknowledges Walter. Broyles, with a look that clearly says, "any time you're ready, guys," glances at Olivia, who says Pekarsky's report says the kid looked normal when he was picked up. At which point an FBI agent comes out to say they found something in the file room: a few dozen reports of strange stories about deformed people.
Olivia notes that the reports go back as far as thirty years ago, and reads from one: "I saw him change in front of me. Suddenly he was hideous." Well, it's either deformed freaks or particularly acrimonious divorce court transcripts. "Misshapen and deformed. It looked like a cousin of Bigfoot," reads another. Walter snorts and says the boy bears no resemblance at all to a sasquatch or even a yeti. And Agent Frug (agent Frug?) is all, "You don't believe in those creatures," and Walter testily says "Why shouldn't I? Just because no one has documented flying monkeys or talking lions yet hardly means they don't exist," and Peter naturally feels the need to apologize for his father and calls him a "shock doc."
Olivia notes that all of the reports were dismissed due to lack of cooperation and hard evidence, but the vast majority happened in the same area: just outside Edina, where the boy was picked up. "I guess that's where we start looking," she says, and everybody gets up to go, but Broyles has a word of caution for her: "Whatever these things are, it seems like they've managed to hide themselves for a while. And from the looks of things, they'll do just about anything to keep it that way. Keep in mind." That's about as close as Broyles is going to get to being all mushy. Olivia glances at the bodies being zipped into bags in the other room, gives him a "yes, sir" and she's on her way.
So the Fringe crew pulls into Edina, with Walter still being a crybaby in the backseat. They stop the car and get out, only Walter doesn't think it's a good idea, and Peter assures him that they're just going to ask a few questions. Walter's beef? There may be werewolves in the hills. Olivia's skeptical, but Walter points to the kid changing in front of his eyes: "I believe we may be looking for some kind of therianthrope." Peter explains it for Olivia as a Greek word referring to a creature that has the metamorphic ability to shift between man and beast. Walter insists he saw one as a young man studying in London, and his indignation at not being taken entirely seriously is a little out of place given the fact that he starts talking about the "fairly potent blend of hashish" he was on at the time, not to mention the fact that just a moment ago he thought the inbred banjo-picker in Deliverance was a real person. Olivia interrupts the nattering because she can hear a faint humming.
