'Marcone(/Dresden?) - John gets fed up of everything in the Supernatural world being so damned messy and melodramatic AND TAKES OVER. Every supernatural entity out there goes from disbelieving scorn to gibbering terror. Harry is like "I told you so", and doesn't know whether to be scared, furious or amused by the fact that Marcone overthrows the White Council in an underhand fashion. If Harry accidentally ends up as spoils-of-war in the process, that would be hilarious.'
I...kind of want to write this fic. It'd definitely be Marcone/Dresden if I did.
