I think I agree with your assessment, Miriel. It's a cool idea but I can't quite see them doing it

Final Cylon: Billy Keikeya imo. (Or maybe Crashdown) But in seriousness, any thoughts on the probabilities of it being a lesser character like that? I can't see them doing it because it'd be hard to have the impact, but on the other hand even if it's someone like Gaeta or Zarek (Both strong possibilities) it won't quite be up there with Roslin or Adama, however dumb it would be to have them. So I fear it will be someone that big a deal. Or they get to Earth and it's like the 25th century, there's one Earth government, and the President of it turns out to be the final cylon.
