Hard to pick, but Andy.
To be honest, if the two have gone that we think have gone, I'll be happy with the final group as they've all been in the game not just sitting on the sidelines smoking their way through the show (in Alex's case).
I'd prefer Andy, Jason, Jayne or Evelyn but I won't mind if it's one of the current group (presumably) left there now as they've all be involved in the show enough to warrant their place, even if I don't like all of them personally.
