I still think Victoria is the Mole... but Craig was pretty suspicious this episode as well. He could have refused to respond to Victoria when they crossed the finish line, but he answered her.

Also, he may not have wanted to act "too suspicious" as to so obviously hurt the team. His finding the clothes could have been planned to redeem himself a little. He has screwed up enough missions that being able to bring everyone their clothes would make him look good. What were the chances that he accidentally walked into the right cleaners?
