Janelle made her deal with chilltown lastnight before any of the veto stuff had started, although she reiterated it just after the beginning of the veto preparation.
I think its more that she made deals and moves drunk (bottle of wine) rather than sleep deprived.......now that everyone is against it she is trying to make it seem like dumb little janie doesn't know what she's doing, while still using the "but I have a bad feeling a floater is going to get us" , she is just trying to play the game, and she tried to use howie to help her get her way not counting on the fact that howie would completely flub it.
