I think Will is going to win. The only thing that might prevent it is if the other contestants react negatively after seeing all the things Will said about them on camera in the diary room.
As I recall, he referred to Krista and Monica as "the two dumbest people I've ever met". Of course, they both probably hate Nicole enough to ignore statements like this, but still.
I'm guessing Hardy and possibly Autumn will vote for Nicole.
Mike, Krista, Monica, Bunky, and Shannon for Will.
Sherry and Kent I'm not sure about but I don't think it will matter.
