It would be really obvious if Leshawna was voted off next, but it kinda makes more sense too. She has way less plot possibility then Heather does. Heather still has to turn nice and she could contribute to the Duncan/Courtney conflict case there are hints of d/h this season and they do get along pretty well. Not that I don't believe in the lame-o-game, it just doesn't make sense for heather to be voted off instead of Leshawna imo.
