As far as I know, you can't get a by this late in the series because it would be unfair. Wrt a two-person final. The Rose and John year, at least they were both incredibly good dancers, both popular so there was at least some question about who would win. A two-person final with Ellie and Layton will be dull because we all know Ellie will win. I mean I want her to win because she's great but it'll be dull because no matter how lovely the dances we'll all just be waiting for her getting the glitter ball at the end.
