The next day, Corinne and Bob set off to get the treemail. The scene at camp Nobag continues just long enough for us to see Sugar bang her toe on a log. Alone, Bob and Corinne agree that tonight would be the perfect time to blindside Matty. Except for the fact that it's also the perfect time to get rid of Corinne that nasty hag. Corinne's hoping that the Fang alliance will do that if he doesn't win immunity, thereby saving them for another three days. Back at camp, the five talk about who should go home next. Sugar tells us that she's confident that their five-person alliance will stick together until the end. Matty thinks Bob should go home next. Sugar says that Matty's the only person who can beat Bob in a physical challenge. Bob is fifty-seven years old. Crystal is an Olympic champion. I'm sorry, I just can't get over how freaking bad she is at this. Sugar says the plan is to vote Bob out before Corinne, because Bob is a much bigger threat.
In the woods, Bob tells Corinne that Marcus never threw that immunity idol in the ocean -- he snuck it in his pocket at hid it at Kamp Kota. But he didn't bring it to Tribal Council with him, so Bob took it for himself. "Is that a legit idol?" Corinne says, as Bob shows her something wrapped in some cloth. "No!" Bob says; "but it sounded pretty good, didn't it?" It did to Corinne, and if she's the self-proclaimed smartest person in this game, then surely it will convince the other mutants. Bob says he's going to put another fake idol together and explain its existence with the story he just told Corinne. Damn ... that might be genius. Although, if Bob had that all this time, why wouldn't he have used it before? He could have given it to Randy to double-blindside everyone. Surely the Fang Five will think of that and realize there's no way this idol could be real. Bob tells us he's going to make his second "very good" fake idol and let it slip to someone on the Fang alliance that he has it, so they'd better rethink their voting strategy. Corinne says this will only work if one of them wins immunity today. "Well, we'll do that," Bob says. Corinne is very pleased that someone has once again done the thinking for her.
Immunity challenge! Today we get the trivia challenge. Probst will ask questions about Gabon. For each answer a contestant gets right, he gets one ball. Once all the questions have been asked, the contestants will throw their balls at a big target at the bottom of a hill. Whoever's ball is closest to the center wins immunity. As always, this is Susie's challenge to lose!
