@Joe Nation,
Yeah, I thought it was pretty idiotic, too. Troy did have a good plan.
My wife was speculating that maybe Tarzan thought that the votes were going to be split between him or Lief. So, he thought he would tip the scale, maybe?
Either way, you never know how folks are going to go, although figured that Christina and Alicia were going to vote along with the other women, and not Troy.
The only reason that that Kat is still there, as she's useless, as she's part of the alliance. The moment I saw her jump off the beam in the water challenge for no reason, early in the game, she should have been gone.
