Mine is Sandor Clegane. The dude has been traveling a literal and figurative journey of change through this series. I want to see him make it to the end and have his brother roasted. Best by his hand, but having one of Dany's dragons torch him would be great. I would settle for a bro battle as well that ends in fire. Maybe Sandor finally overcoming his mental block with fire long enough to vanquish his brother with it. It only seems fitting that his freak brother should have his abuse of fire when they were younger come back to haunt him.
