Carter won't be joining them because he's got another mission: breaking into the bunker with Zane, Allison, and Allison's ugly dress. On the way down, the group exposits all of the strange things Eva's done since arriving in Eureka, just in case you haven't been watching or paying attention this season. Allison says this place is like a window to Eureka's past, but Thorne seems to want that window shut. I like shutting my windows, too -- my ghetto apartment doesn't have screens so when I keep the windows open it lets the bugs in. Allison enters the bunker easily by entering in the security code she apparently knows. Way to keep the place sealed off, Eva.
Zoe and Lucas run into Kylie taking atmospheric readings for Henry outside Café Diem. With the authorities gone, Zoe apologizes to Kylie for her earlier comments. "You mean when you sold me out?" Kylie says. Sold you out nothing, Kylie -- you were trying to get Zoe to share half of the blame for something that you were completely responsible for. "You made a second sun!" Zoe cries. Yes, I think people who make second suns should have the whistle blown on them. But Kylie says Zoe's just like every other politician: she'll say anything to get what she wants.
Having easily broken into the bunker, Zane scans the area for fusion reaction leftovers and finds none. Carter asks if that's a good or a bad thing, and Zane answers that it means they aren't being irradiated. I would have found a way to test that before actually entering the site, but there you go. "Rats," Carter says. Allison explains that not being irradiated is something to cheer for, and he says he literally meant rats -- they're all over the place. Allison and Zane don't seem to mind, but Carter hates/is scared of rats, making him the subject of Allison and Zane's derision. Zane says he's not finding any evidence of materials that could fuel the mini-sun as Allison waxes nostalgic about Eureka's past and what the bunker can tell them about it. She can't believe such a huge plot contrivance could have been hiding underground all this time. With that, she finds the door to room 307.
