The roommates are all hiking. The on-screen text informs us that this is the "Gorkha Region, Nepal" as we hear some Nepalese singing in the background. Irene tells us that "'trekking' is a long word for just walking a hell of a lot." Actually, "trekking" isn't that long a word, but I'm not here to pick nits. Oh wait -- actually, I am. More trekking through the countryside. Mingma explains that in the previous regions they visited, there are generally a lot of Westerners, so no one notices them. In their current area, Westerners are a novelty, so the kids are all following them around. Oh my God! Nathan just did the meanest thing! He turned to a group of little kids and growled at them, and they all ran away. Way to foster international relations and break down cultural stereotypes, Hick-Boy. Trekking, trekking, trekking. Rebecca tells Kelsey that she's "changing." Her clothes? Oh, she means mentally. Rebecca voice-overs that she has been "blessed with the discoveries" as we see her crossing a ravine by walking on a downed tree, and admiring a Nepalese baby.
All the trekking has led them to a rope bridge crossing a giant canyon. Nathan describes it best, when he says, "This is Indiana Jones and the Temple of Doom." They let Stephen go first, which is a bad idea. Given his anger-management problems, I wouldn't be surprised if he got angry because David stepped on the back of his heel, and ran ahead and cut the ropes, leaving them all to plunge to their deaths. But at least it would have been more entertaining than Rebecca's Spiritual Awakening. Stephen starts shaking the bridge and jumping on it, which is not as bad as cutting the ropes, but is still annoying. Apparently, they made it across the bridge alive, because the scene just ends.
Now, they are in some village and Irene tells Stephen that the battery is dead in the tape recorder. In an interview, Stephen complains that everyone is always asking him to teach them stuff, when all they have to do is press record and talk into the microphone. On the one hand, he's right. On the other hand, he's the one who appointed himself "executive director" of the recording process, so maybe it comes with the territory. They manage to record some villagers singing.
