So Vimes on highler this coronation he thinks he sees a dragon like flying out some fog but it's just a crow. The fight was just a complex mating ritual and so they fly off to be together. A patrician who when he was overthrown was thrown in the dungeon is fine because he had trained a bunch of rats as his right hand man. He says our people who will follow any dragon worship any god ignore any iniquity all out of a kind of humdrum everyday badness not the really high creative loathsomeness of the great sinners.
