Things weren't looking good for Yau-Man from the beginning of the episode when his teammates started discussing his elimination before they had even had an immunity challenge. So, when they did finally make it to the immunity challenge, and his team lost, he was basically doomed. Most of his tribe figured he was someone they would never be able to beat if they were to make it to the end with him, so why not get rid of him now? And they did. Poor Yau-Man! You were robbed!
