James had both idols, but he needed to 'use' one before the votes were read to nullify the votes against him. He thought (wrongly) that his tribemates would not vote aginst him, so when they did, it surprised him. Thus, he was eliminated without getting to use the special advantages that he had.I assume that the idols will be out of play now - they were only good until the final 5 anyway, so although it would be possible to hide them again, the survivors only have one episode to find them, so I don't think it will happen.
