CQCStargaryen

I think it's a cool theory, but I HIGHLY doubt that the show will make this reveal. Maybe Tyrion will be a dragon rider. But maybe Bran will warg that dragon. I guess we'll have to wait and see.

I have a very random question. I need all of you who are knowledgeable in both the book and the show to help me out here. Humor me here. In a completely hypothetical situation, let's say that Tyrion is actually the bastard son of Aerys II and Joanna Lannister. How could the book, or more specifically the show, go about revealing this parentage?
