The next stop on the show's world-wide tour is exotic China, where Chris announces that each individual will be on their own for a race down the top of the Great Wall. Duncan and Alejandro work their strategic faux-friendship. Sierra, meanwhile, continues to tell Cody that they are married and he is forced to pursue desperate measures to lose her from the game. Blaineley cannily persuades Chef to help her cheat but he has a tougher time in the crazy and daring food-eating competition that follows, featuring all kinds of very authentic - and tough-to-swallow – local delicacies.
