ah see but i did warn against going full lotr… in any case, i have a hard time seeing the role of ____ in the north being anything but a shared role (again, with the dear hope that the remaining starklings survive…). funny enough, d&d almost got it right with the judge/jury/executioner gimmick they pulled with sansa/bran/arya. but they failed in that it was a very dumb way to display shared power, it lacked context, it was preceded with so much bullshit between arya and sansa, and nothing about bran or arya or sansa is right in the show. absolutely nothing. but if the remaining starklings do make it back to Winterfell, I believe they all will have roles in ruling it. I just don’t think it’ll be as narrow as the show portrayed it.
as a little aside, i’m always a little wounded when i see arya basically forgotten as part of the hierarchy at winterfell. arya is, quite frankly, the most charismatic starkling. she is very good with people, very empathetic, she makes friends naturally, and she has sharp judgement. she really doesn’t have to be embroiled in political drama in order to be a future political player, especially not if the north is going to return to an isolationist state. but that’s a discussion for another day.
as for the valyrian steel weapon for arya, i’m partial to a dagger so that she can still use Needle. but that’s just dreamz.
