It involves two important characters and has an outcome we can totally see happening: Jon Snow (Kit Harrington) killing Cersei Lannister (Lena Headey).Writes Dremling:To quote the end of Cersei’s prophecy, “When your tears have drowned you, the Valonqar shall wrap his hands about your pale white throat and choke the life from you.”Since the Valonqar is Valyrian for the little brother, most people think that Jaime, or maybe Tyrion, will kill Cersei. If there’s any family that has a score to settle with Cersei, it is House Stark. Jon’s Targaryen connection remains a secret to many in Westeros, but it seems likely to play a big role in the episodes ahead. Jon may not actually be the illegitimate son of Eddard Stark (Sean Bean) as we were led to believe for so many seasons, but he is still Ned’s nephew. [via: Reddit; h/t: The Independent] I think that in a show as unpredictable of Game of Thrones, this is too obvious. But saying this in Valyrian suggests that the person will have Valyrian blood.The Targaryens have Valyrian blood. So Cersei’s murderer could be anyone who is a little brother. Jon Snow is a Targaryen. The last Targaryen to sit on the Iron Throne, Aerys (also known as the Mad King), was killed by Jaime Lannister (Nikolaj Coster-Waldau), so there’s a symmetry to a Lannister ruler being taken out by a Targaryen.Let’s not forget the Stark angle, either. He wants to kill Cersei. There would make for some poetic justice, that’s for sure. We may not find out whether or not the theory is correct during “Game of Thrones” Season 7, but with the following season being the last, the answer is definitely coming. He is the little brother of Rhaenys and Aegon. I think it is very likely that he does.This theory works for a number of reasons. Posted April 20, 2017 by Stephanie Topacio LongThere’s nothing like a good “Game of Thrones” fan theory to get you through the months when the HBO fantasy drama series is off the air.Lately, a theory posted on Reddit by a user called Dremling has gained popularity. The Valonqar means “the little brother”, not Cersei’s little brother.
