The book also mentioned something interesting about Tyrian's birth. Tywin Lannister and King Aeres II were very good friends in their youth. He made Tywin his hand when they were both young men in their early twenties. It is said that the King was a real womanizer and screwed around a lot. It is said that after Reagar was born, his wife had seven still births or miscarriages. The babies were all deformed, some with large heads, some with tails or wings. He also had an eye for Joanna Lannister, Tywin's cousin and new wife. It said that Tywin was so worried that he sent his wife and the twins back to Castly Rock to keep them away from the King. When Tywin's father died, he had to return to the Rock for the funeral and to settle the affairs of the Westerlands. The King insisted on going with him. King Aeres was at Castly Rock for some time, again, close to Joanna. Within a year after that, Joanna gave birth to Tyrian Lannister and died giving birth. It was at that time that Tywin quit as hand of the King. If Tywin suspected that Tyrian was not his child, he would never admit it out of pride and be seen as the cuckold. It would explain his break with his friendship of the King. Tyrian being born a dwarf goes with Aeres other deformed babies that didn't make it. The King later had a second successful child born, Viserius, after that fallowed by another miscarriage. Danyrius was born shortly after the King died. Her mother, the Queen, also died in childbirth. It is very possible that the reason that Jon Snow, Tyrian Lannister and Danyrius Targaryen are the three main characters of the story are because they are all related. All three of their mother's dyied in childbirth possibly and they may all have the blood of the dragon. Millisandre, the red priestess, saw something in Jon. She knows. The red priestess in Volantis stopped in the middle of her speech when she she saw Tyrian in the crowd. She knew something too. There are three dragons. We'll see who rides them. Just remember that you heard it here first.
