Bran is The Night King
Some fans boiled this theory down to simple similarities in character outfits. Others dug a little deeper into their explanation as to why they thought that Bran is The Night King. The theory comes down to the idea that Bran has been continuously going back in time to try and save mankind from the White Walkers. With each failing attempt Bran eventually ends up getting stuck inside the Night King through a series of time loops. Bran is warned by the old three eyed raven that although “It is beautiful beneath the sea; stay too long and you drown.” That’s how Bran would get trapped in the first White Walker, who becomes the Night King with all of Bran’s powers.
Cersei will Die Giving Birth
This theory feeds off the Maggy the Frogs prophecy. For those who may not know in the first episode of season 5, Cersei visits the local fortune teller, Maggy the Frog. Maggy tells her that she will marry “the king” and become the queen (for a time) “but another younger and more beautiful woman will cast her down and take all that you hold dear.” (the mother of dragons?) Next, Maggy predicts that Cersei will have three beautiful children who will wear golden crowns, but also golden shrouds (accurate prediction of what has happened). Next, Maggy says something that has stuck with many Game of Thrones fans from that day, “And when your tears have drowned you, the valonqar shall wrap his hands about your pale white throat and choke the life from you.” Valonqar is High Valyrian for little brother, which has led us all to believe either Tyrion or Jamie will take her life… but others suspect something a little different. If Jamie is who impregnated her (obviously) and she dies during childbirth, it is then Jamie who ultimately killed her. (what a twist!)
