Joe Anglim (original Bayon, Ta Keo after 1st swap, Bayon after 2nd swap)
Following Episode 7 (the merge): While Joe is atop the dominant alliance in the game, he will need to continue to win individual immunity challenges, because the moment he loses one, he will become a target. In my estimation, Joe should not be crowned Sole Survivor unless he attends at least two tribal councils without the immunity necklace around his neck and survives those votes without any intervention. Of course, had someone else in his alliance won the immunity challenge, he probably would not have been voted out, because of the venom toward Kass. At the same time, with Fishbach waiting for his opportunity to strike, Joe will have to be very creative in maintaining his relationships with others, notably Spencer, who is a good sounding board for strategy.
