Ah, but wait! Eva and Zane are still looking through the journals and notebooks to find out if Team Perkins managed to figure out some kind of cure. Zane's found schematics for a bomb, but little else. Allison gets all pissy that the scientists would waste their last month alive working on a "doomsday weapon." Um, no one said "doomsday weapon," Allison. I believe it was "big bomb." Don't get all dramatic, now. Eva defends her brother's honor, saying he was looking for a cure. Carter, of course, has the brainstorm and says the bomb might have been the solution. He asks Zane if there's anything in there about the bomb creating a whole lot of non-bariogenic radiation. In fact, there is! The bomb has enough juice in it to irradiate ten square miles -- enough to fix the groundwater. Zane says there's one problem: they don't know if the guys were able to make the bomb at all. Eva says they would have done as much as they could before time ran out.
Zane heads back down to the bunker, which means he'll be saving the day instead of Carter for a nice change. He makes it into a room where some kind of particle scanner Allison's using on the surface has detected a signature. Of particles. Bomb particles, I guess. Zane finds a metal wall that the signature must be behind. He presses a couple buttons and, lo and behold, the metal wall lifts open to reveal a bomb. Zane reports that the scientists got "pretty far." He'll finish it off. Why were they making a giant cure bomb in the first place? Wouldn't setting it off totally annihilate them?
Zane gets to work. He says it'll take him a couple hours, but all we see is him stick a bunch of wires on it and it's done. "Great work, Zane," Allison says. Zane actually gives Eva's brother all the credit. Aw, he's not a total asshole this week and is even sort of not selfish! Hooray! Before he leaves the bunker, he chalks his name on the bomb below the names of the other three scientists. In Henry's garage, there's a great deal of noise as all three bodies roll over in their coffin shipping containers.
Zane's back at GD with Allison, Mansfield, and Hendrix, who's been brought in to instantanium the bunker (again) to prevent the nuclear blast from going up and destroying the town instead of down into the groundwater, which would save it. Zane and Allison are kind of bitchy to Hendrix, who's only trying to help and do the best he can. He assures them that his instantanium will hold back the explosion, no problem. Right. Let's all be honest here: a nuclear explosion underground would blow the shit out of the mountain no matter how much instantanium you stick on the bunker exits. But I'll suspend disbelief if you will! As for Mansfield, he can't help but remark on the fact that under Allison's leadership, GD has created a problem so big it will require a nuclear explosion to fix it. Not understanding that this might not be the best time, Zane says "how cool is that?" Yeah, Zane. Atomic bomb explosions are so cool. Those people in Hiroshima and Nagasaki had an awesome time. Douche. The moment Zane creates is so awkward that everyone scatters and goes in opposite directions except for Hendrix, who's left standing by himself with no idea where to go. I like Hendrix.
