If you thought that one big "Game of Thrones" theory about R+L=J was mind blowing, you know nothing, Jon Snow.
Another "GoT" theory is taking over the Internet, and this one changes everything.
The Theory On Tyrion's True Parentage
The theory speculates that Tyrion may not actually be Tywin's son, but rather the son of the Mad King, Aerys Targaryen.
According to Mashable, the fan theory suggests that Tywin's wife Joanna had intimate relations with Aerys while Tywin served as Hand of the King. She became pregnant, and Tywin tried to abort the baby. His attempt then led to Joanna's death and Tyrion becoming deformed.
If the theory is true, it actually explains a lot. For instance, it sheds light on why Tywin is always so salty to Tyrion, saying stuff like," You are no son of mine," and not making him heir to Casterly Rock.
Other evidence includes Tyrion's description in the books. Author George R.R. Martin writes that the character has hair that's so blond it appears almost white and that he possesses a "morbid fascination with dragons," both of which are Targaryen-like qualities.
Perhaps the most convincing piece of it all is when Daenerys hears, “The dragon has three heads,” in the House of the Undying. The three heads of the dragon would then be herself, her half-brother Tyrion and her nephew Jon Snow, whose real father is suspected to be Rhaegar Targaryen.
We would go on to remind you now that GRRM has already said some fan theories got it right, but if this was any more mind-blowing you'd probably end up feeling like Oberyn after a fight with the Mountain, and that's not good for anyone.
