Ok. So... is Tyrion a Targeryen/Snow?
He also was able to communicate with / keep docile the dragons (in the cave where they were chained). His mother also died giving birth to him. Do non-Targeryen women die when giving birth to Targeryen men? (Dany's still-born fetus looked dragon-like, but she was able to carry it.) Is that why that line has so much incest? Tywin always hated Tyrion. Right before Tyrion killed him, Tywin claimed that Tyrion was not his son. Was he being literal? Could the Mad King have impregnated Tyrion's mother? There are three dragons. Are there only two dragon riders / living Targeryens? And if there are 3 Targeryens alive, and we have met all three, it doesn't seem plausible that it be anyone else. Ep1, S1 Tyrion claims to Jon that dwarfs are treated like bastards by their fathers. What if he was treated like a bastard because he is one?
