Hurley & Dave

Background
For some reason, we never see Dave. Hurley claims that he is on his team with him, but we never get to see him. It looks like Hurley is competing by himself. Hurley appears to have talked to Dave, but it just looks like Hurley is talking to the air. Right now, The JayGT Police Force are looking into the situation to see if Hurley is participating alone, which would be cheating, or if Dave is just invisible, which is fine.
