I really, really liked the episode. I enjoyed seeing it from Castiel’s perspective and I liked the way it showed Dean and Co realising stuff as well. Think the direction this episode took was very brave. Dean’s reaction - about Castiel being family and so on - was just perfect, so in character and so Dean. I loved Sam’s reaction, too.
Some touches that I loved:
-Me and Mrs Jones playing when Crowley and Castiel met - thought that was genius.
-‘This makes you Lois Lane’
-Crowley being Crowley.
-Castiel’s thoughts about Sam and Dean being his friends and thinking about protecting them
I’m so looking forward to the double finale.
