[SPOILERS, SPOILERS EVERYWHERE]
In the HBO series 'Game of Thrones,' three characters stand out as the fan favorites due to their wisdom and wit. Daenerys Targaryen (Emilia Clarke) has a fan base as faithful as the Unsullied, and Jon Snow (Kit Harington) proved the importance of his character when millions of fans swore to stop watching after the tragic season finale. Tyrion Lannister (Peter Dinklage) has always been the underdog who refuses to be brought down.
The three characters are also the ones in the running to win the Iron Throne, but could all three possibly be related?
Theories about Jon Snow's lineage have already emerged, stating that Ned Stark's bastard may actually be the son of Rhaegar Targaryen, who is Dany's older brother.
A new theory has recently become public, where fans speculate that Tyrion is the result of the rape of Joanna Lannister by Dany's father Mad King Aerys Targaryen.
During the Anniversary Tourney that celebrated the tenth year of Aerys' coronation, the Mad King had made a joke about Joanna's breast that made her husband Tywin resign as the Hand of the King. Although this doesn't lead to anything in the book, fans point out that Tyrion was born around nine months after the event.
Tywin Lannister (Charles Dance) also famously disowned his son right before Tyrion killed him with a crossbow. Although some might consider this a scathing remark about Tyrion's treachery, some fans think Tywin finally realized that Tyrion might not be his son and is just as mad as Aerys himself.
Fans are also pointing to the prophecy of the Three-Headed Dragon that was told to Dany in the House of the Undying. Daenerys was obviously one of the dragon's heads but the other two heads would also have Targaryen blood.
Fans speculate that it is hinted upon when Dany finds herself in a Dothraki tent (Dany herself), the Wall (Jon Snow) and a throne room (Tyrion, who currently rules Meereen).
The truth might finally be revealed when George R.R. Martin releases his new book 'Winds of Winter.' Or fans can watch out for the sixth season of 'Game of Thrones,' which airs in 2016.
