I think the only reason Xavier got the pass was because of 2 English lads that were out, contacting home. It was Dana's punishment to them.
Of course no way should a guy that already got beat get a free pass to the semi's... I hope he gets his arse handed to him again.
IMO it would invalidate the whole competition that a guy who got beat in the first round went on to win the thing. Unless he has a rematch with Brad in the semi's to redeem himself. Thats actually the fight that makes the most sense for the semi's,
