User blog comment:ImperiexSeed/The oldest being, archangel or leviathan?/@comment-71.183.14.109-20150927160730

When did it say cas was anything other than an angel or a mutated one at best? Id like to hear that.. Obviously there will be plot holes. But death did say arch Angels helped God beat back the darkness. Maybe then God tried making other creatures like Levi's, then found that they killed arch Angels them locked them up? Or maybe they can't... Best off asking death or God. No arch Angels are left any more unless the trickster is around somewhere :) people who think the bone is the only weapon must be wrong I think that is the only weapon that can sort out Dick Roman. Otherwise how would they be so many leviathans chasing dean and castiel? They only used the bone once and there was lots in pergatory.. I'm guessing that weapon might make the other ones able to kill?
