There were a lot of questions heading into the final season of Game of Thrones : What really motivates the Night King ? Will dead Starks rise from their graves ? How might Jon Snow react to learning the truth about his parentage?

Those matters are important, but in addressing them, the show seems to be neglecting some vital mysteries about Bran: Is Winterfell wheelchair-accessible? Whos supposed to check on Bran? Wasnt he cold waiting up for Jaime Lannister all night?

Bran (Isaac Hempstead Wright) uses a wheelchair since he lost his ability to walk after being pushed out a window by Jaime Lannister (Nikolaj Coster-Waldau) in Season 1. It makes sense that Bran wanted to be there to stare Jaime down when the Kingslayer arrived at Winterfell in the premiere, but it also doesnt seem like the best idea to stay outside at night in the middle of winter.

Les Stroud, Canadian filmmaker and star of Discoverys Survivorman , told HuffPost that Bran could definitely be risking hypothermia.

He noted that it doesnt seem too cold in Winterfell at the moment and that its quite possible to sit out all night, but added, Not without covering up his head with the fur.

There are so many mysteries involving Bran right now, even the Three-Eyed Raven would probably have trouble explaining them. Thankfully, Game of Thrones writer Bryan Cogman agreed to hop on the phone and clear up those questions and more. Cogman penned the most recent episode, A Knight of the Seven Kingdoms, along with several others throughout the course of the HBO series.
