Walter happily identifies people in old photos in the living room, and then asks Teddy if they have more recent pictures of his mother. "We don't own a camera," says Teddy. Under his breath, to Astrid, Walter says, "No, of course. Cameras have no optic nerve. The photos would only show their deformities." Well, sure. But going by the logic on this show, when people look at the pictures, their scrambled optic nerves would only show magical undeformed people. Windows and mirrors don't have optic nerves either, yet I'm guessing that reflections appear to be normal, otherwise every visitor to town would see deformities in every pane of glass and polished surface.

Anyway, all of a sudden Teddy seems to realize that he's not supposed to have strangers in the house, and Walter agrees, but asks if he can use the bathroom before they leave, and Teddy reluctantly directs him there. Astrid stands around looking awkward until she sees the game Operation sitting there. "Oh, I loved that game!"

Meanwhile, Olivia and Peter are still mulling over the case, realizing that Joe Falls is in his 30s, too young to be one of the soldiers tested in the experiment, so it must have been his father. "I guess folks with that kind of deformity don't tend to leave home," says Olivia. I don't know. Have you seen peopleofwalmart.com? Speaking of which, Peter's still puzzling out the census data, and he says that going back 30 years, the only time the population goes down is when somebody dies. "What about when people move?" asks Olivia, as they arrive at wherever it is they're going. "No, that's just it. They don't. Nobody ever leaves this town," says Peter. Olivia asks if he's saying that he thinks everyone in Edina is one of them, but before he can answer, they see the sheriff's car arrive, spotlight shining through the windshield. It's not bright enough to prevent Peter seeing the gun aiming at them from the passenger side. "Get down!" he yells, as the deputy opens fire. They don't call it the shotgun seat for nothing. Peter and Olivia run for cover in a nearby barn, with Olivia returning fire.

Meanwhile, back at the Falls' house, Walter is completely lost. He listens intently, hears a low humming. He's going down into the basement! Hey, wait a second -- if the machine produces a hum that's loud enough to be heard in town, shouldn't it be earplugs-necessitatingly loud out here? Well, maybe the machine Walter finds in the basement also produces an electromagnetic pulse that targets the eardrums and makes everything sound the same volume. Also: magic!
