In season 4 of Game of Thrones, Bran Stark and his brother Rickon were marching with Hodor, Jojen, and Meera towards the giant weir-wood tree on the hill where the three-eyed crow was.
When Bran asks the crow if he can fix his legs, the crow says that that is beyond his power. Heartbroken, Bran's eyes begin to fill with tears, but the crow responds:
You will never walk again, Bran... but you will fly
What does this mean? How can Bran fly? Does his ability of warging will help him fly?
Can anyone answer these questions without spoiling any events from the coming seasons?
