My question is whether a marriage between Daenerys and her nephew Jon could work as part of the story's climax. I suspect many readers would regard it as too cliché of an ending, but I wonder if it really needs to be. Suppose the marriage is entirely political in nature and that they do not even end up liking each other. I can easily imagine them smiling and holding hands in front of a cheering crowd, only to sullenly leave for different parts of the Red Keep as soon as the doors are shut.
