An entre ad break later, they replay the last few seconds of the previous act, and then Peter and Olivia belatedly lose radio contact with the command center. Though fortunately and inexplicably not with each other. Peter says they don't have much time. Meanwhile, Diane Burgess's arm is starting to freeze up the same way Gillespie's did, although she hasn't taken hold of the briefcase. Now, see, right up until this moment of the episode, I've been assuming that the device sending the detonation signal is in the briefcase, and our heroes are going to feel pretty stupid very soon. But then we see that Gordon is in fact in the station, watching from a bench, unaware that Peter is watching him. As Gordon gets up to leave, Peter moves in, tackling him to the ground and commencing a crunchy beating. A small remote device flies clear, and as Peter continues thumping the highly trained Army Colonel, Olivia snatches it up and fiddles with it, as Burgess continues to congeal. Walter's up to 26, and Olivia can't figure the damn thing out, so she drops it on the floor and clubs the shit out of it with her cane. Looks like her accident came in handy after all. With the signal killed, Burgess collapses to the ground, not only properly squishy again but still alive. All the FBI's gear comes back online, and Broyles sends in his men, who have a bit of a time pulling Peter off of Gordon. I had no idea he was that invested. Olivia goes and helps up Diane. Walter claps his hands childishly, and even Broyles indulges in a startlingly uncharacteristic display of emotion at how narrowly they averted disaster: he smiles.
