Question: is tywin lannister a targaryen?
Answer: He's a Secret Targaryen The hypothesis goes like this: Tywin wasn't Tyrion's father, and he's actually the child of Joanna Lannister and the Mad King Aerys Targaryen. ... After Tyrion shot him, a dying Tywin choked out a damning sentence: “You're no son of mine." HBO. This would also fit in the three-headed dragon theory.
