Obviously Sharon. Talking the boys out of keeping Nat, who is the best person to take to finals if you want to win, then suggesting a tie to bloody Shelia's hands... After this week if Sharon stays she has 3 guaranteed votes, and she will just need one more vote from someone the other person pisses off between now and the finals. When hasn't someone pissed another off enough in the final 5 to make such a difference? Nat will be mad as hell at TC if she leaves this week, that could be her 4th vote right there.
