Oh. My. God.
Jon.
He really is a true-born Targaryen, not a bastard.
*faints*
So he was the grandson of the Mad King and Dany was the King's daughter. Who has more right to the throne, him or Dany? But really. It doesn't really matter much since Jon doesn't want to be King. That's the beauty of Jon.
Did Drogon bend his knees to Jon? It really did look like he did!!
