Twenty returning castaways begin their adventure -- and their second chance -- in the middle of the South China Sea.

A gut-wrenching challenge; contestants plead for their place in the game at a heated tribal council; Abi-Maria keeps ruffling feathers.

A family emergency forces a contestant to leave the game; a classic immunity challenge features local delicacies.

Thirteen castaways form the largest merge in the history of the competition; two castaways feud; the individual immunity challenge is a game of balance.

Castaways thirst for a much-needed reward after an intense water challenge; a tribal council takes a surprising turn.

The castaways switch from two tribes to three; a castaway is caught sending a message to another tribe.
