The Devil's Advocate
Call me Dad
if he's not the king of the north, the northerns will no longer follow him... they either gonna say fukk this nikka and go home.. or put sansa dumb ass in chargeYes, no shyt, he wouldn't be King in the North anymore....so what?
The Night King and his army of the dead is the priority right now. Why they seceded absolutely matters, cuz if it was cuz they had fundamental issues with being a part of the Seven Kingdoms, then it could make sense to dig their heels, but if it's strictly because of issues with current leadership, then a coup serves the same purpose. Dany is that coup.
you don't take the roll of king, lead nikkas into a battle against the dead, leave them at home to do some shyt they told you not to, then come back like "hey guys i bent the knee, we're under targ rule again, but ummm lets still continue on with our plans"
shyt ain't gonna work fam
