My gut feeling telling me the older brother will get the throne back some how

Yeah. I think the bro is gonna chill in the background, let his tyrannical little brother wipe out the greedy ones until they revolt against him. So the older bro can have the throne with no competition or opponents, with his hands clean and be known as the best choice. Y'know get people say "he's nothing like the crazy guy we had before" when he messed up or become cruel.
