Dr. Peter was a castaway on Survivor: Kaôh Rōng and he was originally a member of the Chan Loh (Brains) tribe. He formed an alliance right away with Liz and the two immediately strategized. Chan Loh won the first couple immunity challenges, keeping Peter safe. Overconfident he had the numbers on his side and control over Debbie and Joe, the tables were turned when the others targeted both him and his ally Liz, with Liz going home. Chan Loh would win the rest of their immunity challenges until the tribe swap, at which point Peter ended up on Gondol. His arrogance easily annoyed his tribe mates. He wanted to flip on his former Chan Loh tribe mates, but was unsuccessful in having any strategic influence over others. He tried to flip back to his original allies, which annoyed the rest of his tribe and caused everyone to distrust him and he was blindsided and became the 6th person voted out on Day 16.
