As far as I am aware of the series, the trone will be rulled by someone not obvious like Daneris
Some outsider would make a change
As things stands now Jon Snow seems to be the one who deserves the throne and he is the one who doesnt even want the throne. He is King of North just because he wants to defeat the Night King and not because he wants power. He should be King.
Wouldn't it be nice if both Jon Snow and Daenerys Targaryen would rule the kingdom? The traditions of the Targaryans would still remain true since they are related and they are stronger together with both their armies and of course, Khaleesi's dragons.
Also, the characteristics of Jon Snow is good and fit to be a king like when he is ruling the Night's Watch. Probably a lot of people like him because of his background, being a bastard (Not knowing yet the R+L=J theory becoming true) and he has become the most interesting character.
