Why did Tai play his idol on Aubry? He knows he's going to be targeted by Brad. He can guarantee himself a trip to the final 4 with his two idols. While he still got there, he put himself in danger of having to win two immunities instead of one to get him to the FTC. And had he won immunity at 5, he could have given his idol to Cirie, who would have still been in the game. I see no reason how saving Aubry at 6 was beneficial for his game. It was an emotional decision, which is why Tai is not a great player. Play an idol for yourself at 6 and 5. Aubry goes home at 6. At 5, it wouldn't be unthinkable to persuade people that Cirie isn't going to win immunity at 4, so you can get her out then. Then you can vote out Brad or Sarah at 5. You get to final 4, and nobody wants to sit next to Cirie. Cirie is likely voted out at 4. Tai, Troyzan and Brad/Sarah are sitting there. Tai's decisions just baffle me.
