I want more on Crowley and Naomi's past because it doesn't make any sense.
Remember, he became a demon by selling his soul to hit double digit penii Length, but he's made references to them bumping uglies in the Tigris and Euphrates and all that. Maybe they just forgot it.
I'm really glad they stuck with Metatron being voice of god basically though. Kinda surprised they didn't at least make him a seraphim or something, but it seems like he's more OP than any Archangel at this point. I figured he'd know about the Winchesters and all that just from writing for God and such though. Really excited to see how they end this all.
Also, I wish Meg were still around. Perfect demon to cure and then she can be with good ole Cas.
