Bran took control of Hodor, made him retarded in his childhood (past) and sacrificed Hodor to save himself by making him 'Hold the door' (Hodor) in the current time.
@Guy_Brohski: Not a Sony drone, I have all the consoles. I'm just pointing out the obvious. There is nothing good on Xbox One that I can't play on PS4 or PC. Those games you listed: Halo 5, Sea of Thieves, Rare Replay, none are that great and do not warrant a purchase of an Xbox One... The best thing going for Xbox One is backwards compatibility with some Xbox 360 games.
