Mouse hopes King will choose her, so she starts to make the cave as cosy as possible, but that just causes a disagreement with the overprotective Dragon. The pair even fight at the Christmas market, and go their separate ways. Mouse hangs out with the foul-mouthed Brother, while an unfortunate spell renders Dragon invisible and inaudible. Which makes a reconciliation difficult, of course.
