Assuming that Not Nice and Very Dim goes this Friday (and also assuming that the general public _do_ get to vote for the winner, and there are no more tricks up BB's sleeve) then this is how I think things will go.

Jonny and Jade will be third and fourth respectively, both getting roughly 21% / 9% of the votes.
Alex will be second, with 31% of the votes
And Kate will win with 39% (mainly cos I'll phone the number 600 million times from work)

Robert is your fathers brother. (Big brother!)
