I don't know why Jason handed Tai the idol, maybe there's a rule that the super idol has to be played by the same person and they have to have both idols before the votes are read. Sometimes I think Tai is too much of a goof, so while putting out the fire in the middle of the night was great to add more heat to Scott and Jason, I can't bring myself to think he actually did it for that reason.
Julia did some good work this episode, she went from the bottom of the bigger alliance to the bottom of the smaller one but with idols, she's had no solid alliance of her own since being sent to exile so she obviously had to do something. Winning that idol was a game changer, took the target off her back, she positioned herself for the swing for both sides and along with the idol reveals forced the bigger alliance to take out one of their own.
The other alliance had no choice but to vote for Debbie, unfortunately that's killing two birds with one stone since stubborn Joe most likely won't trust them now, but it would have been more troublesome if they voted Joe and kept Debbie. Don't think the guys will be too upset on the Debbie over Cydney vote, since they still have a game changing power in their pocket.
Also Joe instantly volunteered out of the reward challenge, why do old people apply for this show if they can't even compete, might as well have replaced him with a coat tail riding pretty girl.
