I suppose that because Cochran did give the idol back to Ozzie Savaii felt safe that C wouldn't flip but whether or not they should have kept a closer eye on him is up for discussion. They could have lied to him about who was getting the idol just in case BUT, to me, the biggest blunder was DAWN. What was she thinking when she kept C's flipping to herself? She had to know it would be the beginning of the end. As others have said she could have saved them by switching the idol to Keith or Jim. At least they would have had a 50/50 chance and seeing that Keith was the nastiest to Cochran they may have figured it would be him. Dawn screwed her tribe and I wonder if they'll find out. She said she came to the conclusion that she liked her tribe so why did she destroy them. I can see Cochran doing what he did because of who he is but why Dawn unless she was flipping also? Cochran, in his own mind, had a reason to flip so imo Dawn gets the worst player award for the episode and maybe season.
