I will gladly come to Winterfell when the king visits.

[This is still a lot for him to take in. Bran being the king now, and the fact that he himself should be but never will, and not being sure how he feels about that, either. At least Bran will be a better king than the Barratheons or the Lannisters ever were.]

I expect that it will be a benefit to Winterfell to have an ally in the one place that's farther north than you are.
