Rachel is talking herself through her fear on the way up, which is going to be nothing compared to going down. Other Rachel and Dave are doing that now, letting themselves tip forward and allowing the ropes and harnesses take their weight as Dave says, "It's always a little concerning when you're stepping off the ledge of a 44-plus story building." Just say 45 stories, dude. In any case, they're walking spider-style down the end of the tower soon enough. Brendon and Rachel get to the top and soon Other Rachel and Dave are no longer walking, but just sort of dangling as they get gradually lowered down from above. Quite the challenge, there. Brendon and Rachel find the banner from above and Rachel says, "Right now it seems like we might have a 50% chance. I like those odds." They're a little optimistic though, because Other Rachel and Dave have already been winched all the way down to the ground. And also because Brendon and Rachel suck.

The Border Patrol finally reaches the twin towers, not ready to give up. Other Rachel and Dave get back to their driver, Tully, and immediately start talking over each other about where they're going. "Who's the navigator? Let me work it, okay?" Dave control-freaks. I sit back and look forward to when they inevitably get lost.

Back atop the tower, Brendon is telling Rachel not to freak out before they head back down. "I feel like I'm about to pretty much die," Rachel says. Brendon goes first, but if the idea was to reassure her it doesn't work. "I'm not gonna lie," he says. "Going down face-forward is pretty scary." Also, he loses his footing and slides willy-nilly down the side of the building for a fair distance. There's just no way to look cool when that happens. Art and JJ are ready to start ascending, but in case you've forgotten, like I have, JJ hates heights. "It's like you're tempting fate, man," says the man who has spent the entire race talking loudly about how he's going to win the million dollars at the end. Eventually Brendon and Rachel reach the ground. "That was so scary," Rachel says. No, what's scary is the extreme close-up from her helmet-cam as she crawls on the pavement like something out of a Japanese horror movie. They jump back into their cab and tell the driver to go to Sand Island, which apparently they recognized by name from overhead. Meanwhile, Art and JJ get to the top, spot the banner and get ready to rappel down.
