Kelly and BuffJon are just ahead of the Chipsters as they approach Underwater World. Both teams park and run inside. As they do, Reichen hilariously voices over, "It's like, we do everything faster than Jon and Kelly, but then they always go by us at the event." Yeah. You know, running to the event counts as something they do faster than you, and actually, if they're able to pass you in the hallway, it's not like you had built up much of a lead. In this case, it seemed like the Chipsters picked up some time at the Detour and then lost it navigating to the next route marker, so what's Reichen's point? Inside, the teams wind up in a single little clump as they run. Kelly asks Jon to please not push her (heh), and then they all make it to the clue box as a group. They pull the clue, and it's the Roadblock. The hint says, "Just when you thought it was safe to go back in the water." They're surrounded by a shark tank, so if you know your Spielberg movies, you probably know where this is headed. BuffJon immediately points to himself and says he'll do it, but Kelly hesitates. "I think I should do it," she says. Phil, with a shark's face right over his shoulder, explains that in this Roadblock, the chosen person will have to put on scuba gear and walk through the shark tank, dodging a collection of sea creatures as well as oodles of sharks, over to collect a clue from a "treasure chest" on the bottom of the tank. Phil calls the animals a "rogues' gallery of sea creatures." So, you know, somebody is at least trying to write good copy for Phil, which I appreciate.

Reichen takes the task for the Chipsters, and while he knows Kelly wants to do it, BuffJon says, "We've gotta beat these guys," and winds up doing it himself. Considering that she's coming off a pretty unnerving experience at the rappel, I don't entirely blame him for not trusting her nerves entirely at this point, but still, he would ideally have let her have a shot, since it's more than her turn. BuffJon and Reichen both get suited up, with BuffJon winding up in a fuchsia and black scuba suit, while Reichen's is peach and black. So...you know, they're both looking about equally studly.
