This twist AGAIN??:
In addition, throughout the series, at least one castaway each episode will be banished to a separate island (Exile Island) miles away from camp. While being separated from the tribe is not desirable, the castaways will learn that there is a hidden Immunity Idol somewhere on Exile Island. If found, this Immunity Idol could save an individual from being voted out at a future Tribal Council.
SURVIVOR: COOK ISLANDS will feature the series' most ethnically diverse cast to date. The castaways will initially be organized into four tribes divided along ethnic lines (African-American, Asian-American, Hispanic and White) before merging in a later episode.
