I think I may have come up with the oddest HP crossover bunny on record. Reparo!Dean and muse!Marquis de Carabas (of Neverwhere) who both live in my head, have decided they'd like to star in a slash fic together, and are now ganging up on me to force me to write it.
*bangs head on monitor*
I'm going to have to, now. If I don't, the Marquis will sulk and refuse to give me any more darkfic ideas.
