Game Of Thrones: 10 Lesser Known Fan Theories That Might Actually Be True
7. The Hound As The Faith's Champion
Yes, Arya left the Hound to die, but since we didn't actually see him die, so he might still be out there somewhere. The theory is that Sandor Clegane, the only man in Westeros without a religion, finds faith. The faith, to be exact.
After Cersei's walk, she will be put on trial by the faith and her champion will be a member of the kingsguard, the resurrected Gregor Clegane a.k.a The Mountain - and the faith will be in need of a champion. Fans believe that Sandor might be the gravedigger with the monks (in the books), who is dealing with his own redemption, and he might become the champion for the faith.
Even if he doesn't find religion and only uses the faith to kill his brother, wouldn't that be awesome?
If this theory rings true, we could see a deathmatch between The Mountain and The Hound and ultimately we could see Gregor burning "alive" (since the undead aren't really fans of fire) by the hand of his own brother that he tortured with fire.
