Daenarys... she has the most spirit to be rightful and just, Tyrion too.. he doesn't seem as sincere maybe but he also has a good heart and is quite rightful? I like Jon too though, don't know though if he has a right to the throne, to the North, albeit, he does. I think he would be a pretty good warden of the north. Not sure if I like Stannis very much but I did like how he treated his daughter, means he has a heart, those that have a heart like that are usually good rulers. The rest... nah, Tommen is just a kid. Just a gimmick sitting on the throne. Maybe he'll be a good king but he might be too gullible.. (explained by his age maybe.. you might say) .. but otherwise, with Cersei being his mother he might get corrupted.. or something like that. Jamie is pretty good too, his heart is in the right place. It was only Cersei who set his sight on vengeance. Now his bound on killing his brother lol.. which I hope doesn't happen (or anything like the sort).
