Game Of Thrones: 15 Theories Better Than What We Got
10. Bran's Multiple Personalities
Completing the hat-trick of theories based around the eventual King of Westeros, in the same vein of Bran taking the place of someone in the past, there was a theory suggesting he went back in time and lived as every Brandon Stark throughout history.
The Stark lineage is full of namesakes of Bran's, from Bran the Builder to Bran the Breaker, Bran the Shipwright, and Ned's older brother, among many, many others. Some thought that Brandon was more than a family name, with a deeper meaning running through it.
This would have given Bran, who had so much potential going into the final season, much more significance to the story, and his coronation at the conclusion of episode six would have felt a lot more earned if he had built the Wall, been murdered by the Mad King, and helped establish one of the greatest Houses in the history of Westeros.
Though it would have been slightly strange for Bran to have been betrothed to Catelyn during his time as Ned's brother, this is Game of Thrones, and it would have been no stranger than Jon's relationship with aunt and girlfriend, Daenerys.
