A wailing voice takes us over to the challenge area. I feel you, wailing voice. Jeff welcomes the final four. He takes the immunity necklace back from Eliza, and then introduces what they're calling, not unreasonably, a "vertical maze." You can think of it as a really big jungle gym that has the additional challenge of only being traversable in particular ways, and you'll be about right. Each person will be assigned a color, and they'll each go around the maze picking up ten pairs of tiles in their color. When they've gotten all their tiles, they'll untie each pair, and each pair will contain a letter tile. Whoever arranges the letters into a two-word, ten-letter phrase first wins immunity.

"Survivors ready...go!" So as usual, Scout is never in it. It's a battle among the other three, and as usual, there's very little substantive recapping to be done. Because you don't really want to read a whole page of "[person] climbs up" and "[person] climbs down," and unfortunately, nobody's blurred ass hangs out or anything. Suffice it to say that Chris, Twila, and Eliza all perform similarly and adequately. And people keep almost stepping on Scout. Chris eventually stakes himself to a small lead, and although it takes him a couple of minutes to sort out the word puzzle, he manages to win immunity, and is mightily excited, as I think he believes this to have been his moment of greatest peril. It certainly would have been had Eliza won immunity, which she almost did. Anyone else in this final four would have been wise to realize that Chris had more jury votes in his pocket than the rest of them, and I suspect Twila and Scout would have turned on him and gone to F3 with the less popular Eliza and not even been all that heartbroken over it. And Chris knows it, so when he wins, there is much "YEAH!"-ing and fist-pumping. It's one of the few major displays we've seen from Chris this season, actually. Jeff calls Chris over and puts the immunity necklace on him. He then intones that, after thirty-seven days, one of the three remaining women will be taking a powder.
