LAST EDITED ON 03-11-12 AT 04:57 PM (EST)I just read that, according to Bill, it had to be unanimous:
Reality TV World: What I was really looking to ask was last night's episode seemed to go out of its way to suggest that the only way you guys could give up tribal immunity is if everybody in your tribe agreed to do so -- so just to clarify, was that one of the conditions that was in the rulebook or part of the ruling you got from the producers? Because that's something that the show did broadcast but didn't explain in detail.
Bill Posley: Right, right. Once the idea of giving up immunity was put out there, it came to our knowledge that it basically had to be all of us or it couldn't happen. I legitimately felt that either Leif was going home or I had a chance to get Colton, and that's why I went -- I legitimately felt those two things. It was a big move. It was a big move.
ETA: Thanks Dabo, you have faster fingers!
