I know GRRM said that you do not have to be a Targ to ride a dragon. It was quite an interesting tidbit and one that has spark massive debates over who will ride one or be one of the three heads.
Lancel, Osmund Kettleblack and Moonboy for all I know
the list goes on.
One thing seems certain in the fandom, it's Dany and Jon Snow.
Martin has often been compared to Varys in his interviews, he won't lie, but he will often be vague or steer things around.
What if his statement about not needing to be a Targ to ride a dragon is a lot more simple than it seems?
What if the two other riders aren't Targs...but have the blood?
Jon Snow and Aegon
Let's just assume that Aegon is a Blackfyre in this case, he's Aegon Blackfyre, not Aegon Targaeryen. He has the "blood of the dragon" as Dany so loves to remind us and with all the foreshadowing of another Dance of Dragons it would involve two real dragons.
Jon Snow, in this case, R + L = J is true, no secret marriage on the Isle of Faces, no drunken septon marrying them, no polygamous marriage and so forth, he's simply a bastard. He's not Jon Targaeryen, he's Jon Snow...err...Sand...fuck it, Snow sounds cooler. He has the Targ blood, but he's not a Targ.
It seems pretty simple, you don't have to be a Targ to ride a dragon...neither are.
What are your thoughts on this if any? Too simple? Too blasé and typical for Martin's fantastical world?
