From what I was saying on another message board...
I didn't like the twist at all. It's great for Ben, but it sucked for Chrissy who actually won the challenge. Whomever wins the fire building challenge is just going to have another point on the resume. I thought Devon was going to have a good shot at beating Chrissy regardless, if he would have been the one that finally sends Ben to the jury, that's just another reason to vote for him. And if Ben survives (outlasts) yet again, another reason to vote for him.
Am I crazy in thinking that Chrissy's best move right there might have been to save Ben? Acknowledge that he's a strong competitor and deserves a spot in the final 3... but she's looked at as the good guy for saving him. And Devon probably beats Ryan, so Ryan is a jury vote for Chrissy almost certainly. It might have backfired, and hindsight is 20/20 considering Ben won anyway, but I think it just might have worked.
