That's the problem though, he's not even a speed bump to Dany anymore. Even assuming that her forces get drastically reduced in the process of getting to and conquering Westeros, he's got what, a couple hundred wildlings left? And even if people believed that he was a Targaryen, and that Lyanna and Rhaegar were married and he wasn't just a different flavor of bastard, who the hell is going to follow a man who got his entire army massacred because he lost his temper?There better be a payoff for the biggest swerve of the entire story when his parentage is revealed. If the only thing that comes of it is congrats you're a blackfyre instead of a snow it will have been a lot of blue balling for nothing. If it's nothing more than to get him on a dragon it's still a let down. Hopefully it pushes him to something other than reluctant hero. Conflict with Dany over her Muslim/Mongol invasion from someone with legit claims would be nice. Wishful thinking but if it's revealed to the other characters at the end then who really cares in the first place, story's already over. Making us wait when we already know would be lame.
If Jon is exceptionally lucky, Daenerys believes that he's her nephew and agrees to marry him to try and repair the relations between the North and the Iron Throne.
