They arrive on-site in a black van identifying Fringe Division as being part of the Department of Defense and go racing across a sidewalk jammed with people who are all "Oh shit! Fringe Division!" Oh, and don't worry, McNuggets lovers: the alternate universe has McDonald's.
The Fringe team and several footsoldiers enter a beautiful old theater with the music stands and other trappings of an orchestra set up on stage. "Site's secure, boss," Charlie tells Lee, who strides up on the stage and waves some sort of wand that sprays a mist or something in the air. In front of him, the air is shimmery and distorted, and there are red tendrils, looking like tinted light reflected in water. He taps the clip on his ear, which appears to be Alt-Bluetooth and tells "chief" (a.k.a. Alt-Broyles) that it's bad: "We've got Stage 3 degradation," he says. Broyles is watching the action through several feeds displayed on his fancy tabletop monitor. He asks if there are any data indicating the event is contained. Lee keeps looking. Oh no! The red tendrils are all shifty! That is probably not good in this universe! He says they're in potential quarantine mode here. Broyles is all "damn!" and tells him to send up a "looker."
Outside, behind the scene roped off with red police tape, Alt-Olivia interviews a witness (after asking for his "Show Me," which is I guess what they call ID over there). This guy is worried about a quarantine, but Olivia tells him there's nothing to worry about, and asks him for whatever details he can giver her about what he saw.
Inside, on the stage, Lee is holding a silver dollar, and he decides to look at both sides carefully so that we can see one side has the Liberty Bell and the moon, and the other has Richard Nixon (last seen in "Jacksonville"). He kisses it (lucky silver dollar?) and puts it in a small jar of water, where it floats on the surface. He radios Broyles: "We're getting decreased gravity measurements here, Colonel." Broyles, who's wearing a wedding ring -- well, perhaps it's more accurate to say he's wearing a ring that would signify a wedding in our universe -- doesn't look happy.
