Back at GATE -- or, more precisely, below GATE -- Linc and Sucre are back at the pipe where Bellick died. Sucre explains, "You know, Bellick saved my life. Back when we were in [Sona], T-Bag went nuts ... he lit Sona on fire, he told everyone to run. 'They can't shoot us all,' he said. It was a stampede, bro. I was down, I was trampled, I couldn't get up, I couldn't breathe ... but then somebody pulled me back on my feet. It was Bellick. He saved my life." Well, sure, but before that, he did quite a number on you, and don't you forget it.

The guys shimmy through the sleeve then continue to previously-unexplored territory. They're in a big concrete chamber with smooth walls, and the smooth floor is punctuated by inset circles of metal. Sucre's like, "We have to blow up this wall?" and Linc predictably grunts an inquiry as to whether Sucre's got a better idea. As a matter of fact, he might -- why not blow everything up? Here, he'll selflessly step on this MINE embedded in the floor.

David Baker tells Mahone that his life goal is to build an autonomous, self-sustaining city, "a community living entirely in harmony." Mahone asks how close David is to making that a reality, and the mad city planner replies, "Well, that's a matter of opinion. People look at something like this and they think it's impossible. In reality, it could happen tomorrow." Yes, but that would probably require the One World Conspiracy reinventing itself as the One World Nonprofit, and the odds of that happening are ... actually quite good, given this show's pioneering work in implausible plot developments. "This won't just serve the rich," Baker adds, and Mahone's eyes narrow as he draws a bead on Baker's demons. Baker notices, and asks, "How long have you been working for them?" "Too long. I came in in 1994," Mahone replies. Baker grumbles about how he's temperamentally unsuited for day jobs -- "I like to finish a job and move on, put it in the past." Mahone asks, "Do you always leave your name behind, instead of the correct specifications?" Nope -- Scylla was special. Mahone bluffs about the blueprints and we establish that Baker included a legend with the blueprints. Mahone lies about reading that, and Baker concludes, "You're not [One World Conspiracy]." Cut to Mahone quietly freaking out.
