"forgotten why that Targarians ruled them to begin with and why the Targarians intermarried."

So what you are saying means there would have to be another Targaryen for Dany to marry. Is Jon Snow really a Targaryen? Will he and Dany marry and rule on the Iron Throne in the end?

I am positive Jon Snow isn’t Ned Starks bastard.

But I am not so sure he is the other Targarian (and there is another)

But if he is, it wouldn’t keep them from marrying since Targarians married each other anyway.
