So it's Puka and Raro getting to the story questions first, with Puka ahead by a small margin. Both tribes appear to finish at the same time, but Probst suddenly says, "You've got to get on your mats!", which he totally did not say at the beginning. Both tribes jump for their mats, and despite the fact that he was clearly separated from at least one tribe by a black separator designed to keep them from seeing each other's work, Probst announces that Puka has won. Flicka immediately protests that they were on their mat first, although she has no idea either. Jeff does say that Raro has the questions right, so now it's down to Hiki and Aitu for the last immunity spot. Finally noticing that Aitu is not trying at all, Jeff contemptuously says, "Aitu is having a holiday." Hiki finishes the questions and gets the last immunity. It's kind of a bummer seeing Hiki celebrate -- Nate jumps about three feet in the air -- when they win immunity. You know they probably feel like chumps watching it back and not realizing that the challenge had been thrown, but in reality, they still did play better and deserve it, because they were smart enough not to throw the damn challenge. This is the other problem with challenge-throwing: Hiki just got a huge morale boost, because they don't know that Aitu threw it, so they got the same improvement in their frame of mind that they'd have gotten if they won it fair and square.
So when everyone is all situated at the end of the course and Aitu has finally stopped pretending to do things at half-speed by accident, Jeff announces that "after reviewing the tapes," it turns out that Puka and Raro tied at the end, so they'll each be getting two tarps. A tie? A tie? But if it's a tie, how will we know which race is better at obstacle courses? Come on, I want to know! Aitu has earned the right, by losing, to send someone from any other tribe to Exile Island. Billy announces that they're sending Yul, because when you identify someone as smart and awesome and a leader and boffo at challenges, what you really want to do is put him in the position of having secret immunity and being even harder to get rid of. Idiots. Being on Exile Island does not weaken people enough that they lose challenges. It just doesn't. It's only a couple of days, and if you pick a guy who's strong to begin with, he's going to have enough food and water to maintain. It's just a goofy decision, same as it was to let Terry wind up with the immunity idol last time. Yul heads down to the beach to be picked up by the boat.
