Regardless of where she finally ends up after both dances, I think she's still got that "post-Olympic-High-Vote" from the GBP. It may not last long (at least certainly not as long as I perhaps initially suspected), but it may just be enough to keep her safe for a week or 2.
Harsh as it sounds, her emotional state probably wont help her either. I think she's easily going to be the most emotionally fragile of the lot, and I get the feeling the GBP will tire of it fairly soon.
Of course, if she is indeed that emotional, I think an early exit would be the best thing for her. I can't imagine (potentially) 3 months of this will do her any good.
