As Jon Snow (Kit Harington) is now confirmed to be a real Targaryen, assumptions about Tyrion lannister’s (Peter Dinklage) real identity now emerge. Allegedly, The Imp is also a Targaryen, the Mad King’s real son and Daenerys Targaryen (Emilia Clarke) half-brother.

This might be the reason why Tywin Lannister (Charles Dance) hated him so much, aside from blaming him for his mother’s death. As evidence to the claim, the Dwarf of Casterly Rock managed to get up close and personal with the Breaker of Chains’ dragons, Rhaegal and Viserion, without them hurting him.

Mad King might be Tyrion’s father

In George R.R. Martin’s “A Song of Ice and Fire” series, Aerys II Targaryen liked Joanna Lannister, Tyrion’s mother, even before she got married to Tywin.

This, too, might be the reason why Tywin and the Mad King never got along, even they used to be cronies. Daenerys’ father was also talking about “liberties” with Joanna on the exact day of her wedding and bed ceremony. However, it was not cleared what that “liberties” meant. Since then, Tywin got overly protective of his wife.

According to IGN, the Mad King was just trying to stress his power over Tywin, as the latter was richer and more powerful in the kingdom than he was. But his lust for his wife is a big part of the theory that Tyrion is actually a Targaryen.

Maybe, Aerys II had an intimate moment with Joanna. In fact, there were speculations that he raped her after she gave birth to Jaime Lannister (Nikolaj Coster-Waldau) and Cersei Lannister (Lena Headey).

Jamie and Cersei both have blonde hair and green eyes. On the contrary, Tyrion’s mane is gold and silver and has mismatched eye color in the book, although it is not depicted on its television adaptation, "Game of Thrones."

Tyrion might not be a real Lannister

"You are no son of mine," these were Tywin’s words to Tyrion often.

The former Lord of Carsterly Rock always claimed that he was not the Little Lion’s father.

There was even a moment when the senior Lannister said that he had to live with the Hand of the Queen as his son because he had no proof to prove that he was not his blood. He even described Tyrion as “ill-made” as he was born a little man.

He even refused him to be his rightful heir and even put a period on his legacy.

Tywin had been known for being obsessed with their heritage. However, he put Jamie to the Kingsguard, a group that forbidden marriage. Thus, he chose to end their bequest by not handing Casterly Rock to Tyrion. This might be because he believed that his so-called youngest son is not a real Lannister.
