As epic as the Season 8 finale was, I wish it hadn’t thrown such a skewer in my big bang. Serves me right for trying to write canon for once :S
What I want from Season 9 - Dean and Cas go find all the fallen angels (that don’t hate Castiel) and bring them back to the bunker, where Sam starts training them to be a hunter/army against the forces of Hell. woot,
When Castiel dies for the first time, Sam watches Dean grit his teeth and mutter “dumb son of a bitch.” He watches his brother take out his anger in tense, vicious barbs against Zachariah, and then growl out “learned that from my friend Cas” like he’s dedicating Zachariah’s pain to the downed angel.
It’s the first time Cas dies, and the first time Sam wonders just when Dean started to care so much about that angel.
