After the commercial break, an agent has removed the front panel and is poking and prodding at the circuitry inside. Fauxlivia asks, "How the hell is it doing that?" and Broyles says it's not really floating, that there is some sort of magnetics inside. With that, the agent unplugs a connection and the GameCube clunks onto the shelf. Fauxlivia asks if this was the source of the number broadcast. "It's definitely wired to output a transmission," he says, and then he asks for the front panel and the fingerprint powder, and I'm kind of surprised it hasn't already been dusted, and he finds a big fingerprint. "It's impossible to do microelectronics with gloves on," says Broyles, who I would think would have a much higher threshold for things that are considered impossible, but anyway. He wants to get the machine to Walter.
Over at Harvard, Astrid is grouchily accepting several file boxes worth of Massive Dynamic's research on numbers stations, and Peter gets off the phone with Fauxlivia and lets everyone now that they think they found the device that uploaded last night's broadcast and they're analyzing the fingerprints they found at the radio tower. And then there's this confusing sequence of moos, only one of which comes from Gene, and I say confusing because I didn't watch this episode with super-special headphones or anything and so didn't understand Peter's consternation, but it turns out a couple of the moos came from some kind of farm sounds Speak 'N Spell, which Astrid is surprised to see is the property of Massive Dynamic. "It's not theft if you own the company," explains Walter, who says that he's found a way to listen to the tape of the numbers broadcast without losing what faculties he has left.
"The key is analog demodulation," says Walter, and I have no idea what happens next, but it involves a "Jimi Hendrix wah-wah pedal" and the Speak N' Spell, and Walter is able to separate the numbers broadcast from the amnesia pulse. "So we still don't know where the numbers are coming from, but I suspect that the device that Agent Dunham found is the source of the pulse," says Walter. Astrid wants to know the key question: why? Peter's got a theory: "Because they cracked the code, or they came damn close to figuring out what numbers stations are. And somebody wants to keep that a secret," he says, and Walter seems to be over his snit and tells Peter he sounded "very Sherlock Holmes" there. "That would make you Watson, dear," Walter says to Astrid, who might consider switching, considering Walter can pronounce "Watson" correctly and didn't call her "Watchman" or "Jetson" or some such.
