well, harold here is the antichrist and he and michael had a tiny bit of history since michael was supposed to keep him in line...preferably without killing him. i also write sol -the reincarnation of the biblical king solomon- who i had michael as his guardian angel since sol is protected by god as one of his chosen. there's no real reason why sol is chosen, but apparently he is since in history he was gifted with the seal which bears the true name of god and allows him to control demons as well as makes him immune to magical influence. if you want to write with either of them, i'm game for it!
and michael knows trick of course. i figured you'd know that though since they were brothers in heaven and trick is big daddy's bff. LOL
