The only way Annabel would have escaped is if Layton had the least votes and she had the most, so that they would have the same combined score of 5, but pv takes priority.
So as Annabel WAS in the dance off we can be sure that Layton got more votes than Bobby last night.
Annabel seemed to be getting a lot of votes each week - where they then transfer to is key to who is getting the glitterball. I think they will split between Ellie or Bobbie but can't see many Annabel voters now switching to Layton.
So I would say Bobby has more chance of winning than Layton.
