Cas's quote about leviathans killing angels using the aquarium metaphor is also broad, he meant normal angels which are most likely countless of them. Then yes, he's right. His other quote about Metatron is exact, not broad. He says outright that Metatron is older than creation itself. The top archangels Michael and Lucifer should be as well, given that these two are on the list of the five things the colt can't kill in all of creation. Metatron, Michael, and Lucifer are truly rare anomalies in creation. I also think Metatron might highly likely be on that list of five things as well.
