When the time comes I want it to be Arya who crowns Bran the King in the North. Afterall it was the winged wolf who watched over the night wolf when she was at the HoBaW.
Just imagine the scene where the hall of winterfell is brightly lit & all the northern bannermen are present. The Winter Rose is crowning the Winter King and the whole hall is filled with the echoes of the northern lords crying “ King in the North”, “King in the North”!!
