I was having some difficulty trying to figure out which face goes with which name...or even which face goes with which face (from the pictures on the website). Their named "portraits" didn't help me on some of them in the group picture.
If you are needing some help like me (I taped the show, so was able to replay the beginning to get their names), here are their names in accordance with where they are located in the group photo (including the tribes' names).
