Just speculating here, but, if Caryn does go tonight, that means that Tom, Katie, Ian and Jenn make it to the final four. That means:
1. Tom, Ian and Katie will vote off Jenn.
2. Ian and Katie will vote off Tom.
3. Ian and Katie in the final, and (IMHO), Ian will win since he was crucial in immunity challenges. Katie has been nothing more than a schemer.
One of the guys is gone.
Iam is choking.
I think you just nailed the winner...Katie is the only Survivor to gain weight...that's what would happen to me too...LOL
one other thought....Tom would have to win every immunity from now on to stay alive..
