Eva's with the mysterious Dr. Hendrix near the bunker. He reassures her that he's "very good" at whatever it is that he does. She wants him to hurry it up, but he says it takes as long as it takes, since the bunker is huge and a mistake would be very, very bad. Eva offers to send in some help, but Hendrix says the operation is too delicate to trust to anyone but himself. "We only have one shot," he says. "Take it quickly," Eva says. Yeah, for real: the mid-season is about to end!
Jo knocks on the door of Dr. Hendix's trailer. There's no answer, and Jo immediately gives up, cursing Carter under her breath for sending her all the way out here for nothing. And there's even worse news: Zane's there. He followed Jo to tell her that "this passive-aggressive thing is really annoying." Jo says she's happy to switch to plain old aggressive, but Zane thinks about that for a second and wisely decides against it. She walks away and Zane gives up and heads in the opposite direction. But then there's a musical flourish as Jo stumbles upon a small metal canister. She calls Zane back so he can tell her what it is, even deigning to say please. He studies it and says it's a pressurized container on a remote trigger, although he doesn't know what that trigger is supposed to set off. Whatever it is, he says "a device like this" could pack quite a punch. At this, Jo finds a pile of many canister crates and asks what kind of punch thousands of them would pack. Way to litter, Hendrix.
