yeah but on the recap they showed Bobby and Mark make an alliance (oops, sorry Survivor copyright) -coalition. And then Bobby told the audience that he didn't think the mole would do something and then rules Mark out.

Mark: I wouldn't lie to you.

Bobby: I don't think the Mole's going to make a coalition with anyone, I really don't.

Then Clay also does the same thing with Mark, shakes his hand and tells him, "I'm not the Mole." Mark agrees and repeats "I wouldn't lie to you."

Everything is showing us how Nicole wins it (in my opinion) -and since Mark also fits into the winner mold. Remember in the chain gang task, Nicole looks at Mark and he comments to us he knew then it was truthful and not about the game. There's a character transfer thing going on there. One of them is the winner, and one is the Mole.
