Aitu is still ahead a bit. Candice zip lines next, and she gets a bag and heads back. When Brad returns for Raro, Parvati swings down and gets a bag. She's now trailing Candice. When Candice gets back, Ozzy swings down, and while Jeff correctly points out his impressively contorted "monkey pose," I'm not sure he actually did any better than most of the rest of them -- it's mostly about keeping your feet out of the water so there's no drag, and I think there were others who did that just about as well, although their approaches weren't so showy. Ozzy fetches a bag and comes back. He's gaining on Parvati, who's walking instead of swimming back toward shore, which Jeff openly scolds her for. Jeff needs to shut up. It's not like I'm a bit Parvati fan, but I don't think he needs to turn into the Great Jefftini, bouncing basketballs off her head and telling her she'll never amount to anything. Parvati finally returns, and Nate leaves, just shortly before Ozzy returns to shore. Raro did not make up huge ground there on the swimming, even with Brad swimming and Nate swimming. I'm not sure Nate's theory that Brad not swimming totally doomed them in the reward challenge can really hold up. It would probably have been closer, but would it necessarily have changed the outcome? Not sure.

Anyway, Nate swings down and gets a bag of puzzle pieces. He starts back. Ozzy brings back the last bag for Aitu, and he, Yul, and Candice carry the pieces up the ladder. Now, JessiFlicka, Becky, and Sundra are working on the puzzle. Nate finally gets back for Raro, and they all take their puzzle pieces up. The long and the short of it is that Jenny has some kind of crazy puzzle mojo, at least on this particular puzzle, and Raro solves it almost instantly. After sucking wind for the rest of the challenge, Raro actually wins immunity, and why? Because Aitu blew it on the puzzle at the end. Great theory, Raro nitwits, on how crazy it is for a guy to think that it was important for people who were good at puzzles to step up and be good at puzzles. Raro celebrates their victory extravagantly. Jeff hands them the immunity idol. Aitu will now have to send someone home, and they'll have the afternoon to think about it. They head back to camp.

We return to Aitu on Day 18, where Jonathan is giving what I think he intends as a pep talk about how actually they performed very well in the challenge. "It's not like they handed us our asses," he says, sounding even more like Alan Alda than usual. "It was just one of those things," he says. Ozzy tells us that he's "bummed out that someone has to go home." As usual, he sounds halfway like he's stoned, but I think it's actually his hair. I think that secretly, when you have that kind of hair, you talk like a stoner, whether you want to or not. He says that if it's him, then it's him, but he thinks that it won't be. He predicts it will be "someone else." That's quite a limb you're going out on, Karnak: "I predict the person voted off will be one of six people."
