They have played around with the idea that Cass is somehow important or special to God in some way for sure. Like how many angels have we seen killed, and as far as I remember, Cass is the only one God brought back. I don't think your specific question has ever been answered though.Quick question for anyone who can answer it.
Do we know if Castiel was the angel that was charged with snatching Dean from Hell or is he just the first angel that got there?
Because Castiel says Heaven laid siege to Hell. Which implies it was a massive group effort involving alot of Angels. I was just wondering if they were trying to make an opening for Cass to get in or if Cass just happened to be the one that got there.
Does that make sense?
