Loyal viewers of "Survivor" already know all the castaways lined up for "Survivor: Cambodia -- Second Chance" because of their appearances during previous seasons. After 30 seasons, however, the faces of some of the 20 returning players may have gotten a little hazy in fans' minds. Here is a refresher about the Season 31 cast members, chosen by the fans, before the premiere Wednesday.

The two tribes for "Survivor: Cambodia -- Second Chance" are listed below:
