Gordon Holmes: What can we expect twist-wise for this season?
Jeff Probst: Twists this season…I think are going to surprise the players because of how simple it is. We don’t have a lot of twists planned. Our big twist out of the gate hinges on one change in the game. We’ve often done something where we say, “Pick one person to make a decision on behalf of your tribe.” That’s worked well. The nice thing about having one person is that no one knows your lie. So, what we’re saying is you have to share your lie. Two people have to decide whether or not to deceive the tribe. And now you’re linked with them. If you lie, they know your lie and you know theirs. What do you do? Do you get rid of them because they know or are you linked with them to the end? And part of the lie is a clue to an idol. Who gets it?
Holmes: In “Survivor: Cagayan” the chosen players had to decide between a bag of rice and a clue. To differentiate this twist; if you take the clue, you still get a smaller bag of rice to throw the rest of the tribe off of your scent.

(EDIT: To clarify, the way the twist works is two people from each tribe will have to make a choice between a big bag of BEANS and no immunity idol clue or a small bag of beans and an immunity idol clue.)

Probst: We’re hoping at least one tribe takes the bait. Cause when we have our switch, which we always do, people start comparing stories. In a perfect world, the White Collar tribe lies. They live up to their name and they deceive.
