Here's how I see things playing out. We have MM, where Harry will be taking a vacation from his dimension. When he comes back, he has to go through with the wedding. Then we have the wrestling book. In that book Harry, by no means of his own planning, loses winter power. But the favor owed to Molly comes into play with her telling him to leave her. That way he still has coverage from Molly in winter and the White Court through Lara.
