I have to know the answer of why he gave away the final vote.
It was either blind fear of Maggie (judging from his senseless blubbering to Julie, I think this is it,) blind fear of James dominating the game after they got to final 5 (still does not explain why he would give away the final vote, since two are in the finals,) or he's completely retarded, and despite knowing so much about the game did not realize he was forfeiting almost all hope of his team actually winning money at the end.
