This latest Game of Thrones theory doing the rounds surrounds Bran’s importance in the HBO series’ endgame.
Added to this is the fact that the Night King can touch Bran when he wargs.
Bran’s transition into the night King could occur when they pierce the man’s heart with Dragonglass while Bran is stuck inside his body – a theory which seems more likely upon revisiting the season six scene showing the White Walkers’ creation.
Game of Thrones airs in the US on HBO every Sunday where it is simulcast in the UK on Sky Atlantic at 2am.
