yep, as an uberfan and the diabolical genius he is, he should have weighed that more carefully at this point in the game. I could see not wanting to win 3 HoHs though.
I hope he does not out the BG but the DR seems to want to so maybe they'll make him do it during his nom speech. At that point, who cares if they are secret anymore, the others besides Brendon suspect something anyway. I think the DR flat out told Ragan.
