Of course, none of the people in this timeline, except for Peter, realize how much havoc Walter can cause at an investigation site. He tells Peter to "look at this," and to everyone's horror, kicks a hubcap off a car. Then everyone's amazed when he tosses at the truck ahead in line, and it sticks to the driver's door. He's already figured out that the floating objects and the failure of the electrical systems were caused by a brief surge in the area's electromagnetic force, which was so strong it left a residual magnetic force in all metal objects in the vicinity.
Broyles asks if Walter has any idea what caused it, and Walter doesn't, probably because he didn't see the "previously on Fringe" scenes this week, which conspicuously reminded everyone that David Robert Jones stole a bunch of amphilicite, which is very bad news. To figure it out, Walter's going to need some samples from here as well as some of the plane's wreckage and the black box, so Broyles and Astrid head out to get custody of the wreckage and the bodies from the NTSB.
Of course, this being Walter, he just happened to see a sign for a place down the road that serves rhubarb pie. Sure, it's probably open! It's only the middle of the night!
So the team heads down to Westfield, past a sign welcoming people home, so it must be for any of the 584 people who supposedly live here. They pull up at the diner, Walter gleefully taking at its word the sign that proclaims the rhubarb pie to be "the best" in this town of fewer than 600 people. I've got twenty bucks that the menu also proclaims the rhubarb pie to be "world-famous," which is an adjective used with an alarming frequency on small-town diner menus. Olivia can't get a signal on her cellphone, so she heads off for a payphone so she can get an ETA from Astrid.
Inside the diner, they're welcomed -- along with the classic "Will You Still Love Me Tomorrow" on the jukebox -- by a friendly proprietor who invites them to come in out of the cold and have a seat. "Your largest slice of rhubarb pie and coffee, please," says an absolutely giddy Walter. Peter's just looking for the bathroom, and the owner gives him directions. Serving Walter coffee, he starts in with the diner small talk of where they're from and which relatives might be in the area, and then the owner's surprised when Walter admits he had no idea that he was in Vermont. "How does a man drive all the way from Boston to Vermont and not even know that he's there?" asks the owner, not unpleasantly. Walter guilelessly explains that he's not allowed to drive: "I haven't renewed my license since I got out of the mental institution," he says. This throws the owner for a momentary loop, but then he starts guffawing and tells Walter the pie's on the house.
