Olivia's cellphone rings. While she answers it, Walter notes that there are a dozen different amino acids in the sample, which would allow them to survive in the foreign conditions of this universe. Yeah, did you have to give those to Peter when you brought him over?
Anyway, Olivia gets off the phone and explains that there was strange interference with televisions in the area around the warehouse, and plays the recording for the rest of the team, showing us that people were having a grand old time watching elephants stomp around when the screen went all staticky and showed brief glimpses of other programs. Olivia asks if the shapeshifter embryo could have caused that, and Walter figures they did: "I believe that the interfering signal may have originated in the other universe. We may be getting a glimpse into the other side," says Walter, awkwardly looking like he knows more about the other side than he's really willing to get into right now. Olivia asks Astrid to turn it up because she's a super-tough FBI agent who can't work a volume button on a television her own damn self. They slow it down too, and it sounds like voices, although not necessarily human ones. Almost like whale music. "Shapeshifters are soldiers," says Peter, adding that soldiers never go anywhere without orders. Astrid offers to send it to the FBI's codebreakers to see what they can come up with, but Olivia has a better idea: to take it to the super-secretive shadowy corporation with unclear motives and goals known as Massive Dynamic.
In the lab, Brandon listens to it and says it's not language, but math: trigonometric equations, a radio frequency given off like what happens during a solar flare. Just note that I'm going to have to take his word on ALL OF THIS. He says what's interesting is that their astronomical division picked up a surge in solar activity right around that time. He presses ONE button on his computer, which is enough to bring up a split-screen of a solar-flare frequency from last night, and the interference that Peter and Olivia just brought in. But Brandon says theirs couldn't have come from the sun. (I suppose because it was dark?) He doesn't know where else it could have come from, though, so Olivia is all, "Maybe a parallel universe?" and Brandon gets all excited and says, "Yeah, yeah! Because in a parallel universe, time would be slightly out of sync!" LIKE THIS MAKES ANY SENSE. "And the waves would be too," says Peter, helpfully. Then Brandon looks at the screen and goes "Hmm," and Peter and Olivia are all "what?" and Brandon looks around the lab to see what he can use to demonstrate and, much like Nina Sharp's puzzling access to two identical snowglobes in an office that absolutely defines minimalism, Brandon handily picks up two metronomes. TWO METRONOMES. This lab, with all its technology, for some reason needs not one but TWO metronomes. And he doesn't even have to, like, look in a cabinet for them. They're just right there. "Hey, Gary, you using this metronome?" "Not right now, but I'll need it soon." "I'll just be a sec." "Hey, have you guys seen the metronomes?" "Brandon's using them."
