Once the Bishops shut up for two damn seconds they can hear it too, and Walter starts humming a song to it: the prelude from Carmen, and then he starts singing nonsense lyrics to go with it: "Hard artichokes rarely keep, Norwegian elephants, Singapore sleep." Peter asks him what he's singing, and Walter has no idea, says it just popped into his head. Must be the buzzing.
A sheriff Velchik strolls up, and anybody watching this immediately goes, "Well, he's in on whatever's going on," because it's character actor Michael O'Neill, who specializes in hard-ass authority figures -- and if not for him (as Richard Walsh), Jack Bauer's first 24-hour day might have been a whole lot less eventful. Anyway, he notes that they've all gotten acquainted with "the Edina hum" and explains it as huge turbines at the military base five miles down the road.
The sheriff suggests they go for coffee, and once they're inside, seated, Olivia says, "So, I take it you've heard about what happened last night to the three troopers in Jonestown," which is an odd thing to say, because wouldn't that be why he's meeting with them? The sheriff says he understands they took a kid, and Olivia slides over the picture of Teddy (deformed), and the sheriff is all "my god" and he says he's never seen anything like that before, although "Telling those stories is a bit of a local pastime. You hear 'em all over this part of the state."
While Olivia talks to the sheriff about how this boy was picked up by their town, a man at a nearby table gets up and leaves, leaving a perfectly good piece of blueberry pie behind. What kind of madness lurks in this strange town! Meanwhile, the sheriff is saying they get their fair share of sightings but he's never been able to confirm them. "Nothing like this," he says, looking thoughtfully and NOT AT ALL SUSPICIOUSLY at the picture of Teddy. Olivia says they'd like to see the reports, and the sheriff says, after the slightest of pauses, "Of course. Anything I can do."
