This was so awesome. Heartbreaking throughout, but such an amazing pay-off. Obviously, still many questions, but a perfect ending nonetheless.

I found myself affected profoundly by Cas in this story. He has so much more character than his siblings and even other humans. Yet he has had more crap thrown at him than most. To go from a powerful being to a human who is practically dying and still venture on is such a powerful story arc.

WOW. I really loved this. Like, there are no more words.
