What a long, sad trip it's been

I think that in SPN mythology anyway, archangels have a different relationship with each other than they do with lesser angels like Castiel. Although Lucifer was never an archangel anyway, he was the FIRST of all the angels and so he would be much, much higher than an archangel like Michael, but then in Christian mythology it WAS Michael who locked Lucifer up in hell. But this is Supernatural mythology so all the "rules" are out the window.
