User blog comment:ImperiexSeed/The Leviathans Destruction, how's it going to happen?/@comment-4860000-20120309234037

Well we don't know for sure if normal Angels like Castiel can overpower and/or kill them. Leviathans and angels haven't actually met yet, and if witches is able to hurt them i bet angels can too. And we haven't seen the leviathans using any magic yet (except from shapeshifting), so if they can't use any spells they probably can't take away angels powers like Eve could. I think angels will be the answer to their end, and not Archangels because 2 is dead and the last 2 is in "prison". And i dont think the archangel blade will work on them, because if they work on monsters why doesn't Sam and Dean use Raphaels blade on all the monsters they hunted in season 7, like they use the demon-killing knife on every demon they meet.
