This post is dedicated to Castiel's growing emotions.
I snapped
50 caps in total. It's barely noticeable but clearly you can see that Castiel is irritated with Dean here.
Impatience, plus tongue = super hot angel!
Then anger which he displayed several times through the episode. I would also like to throw in a dash of fear because he is talking about a being that could kill him with one thought. That would terrify me.
Throw in a Dean staring at Castiel's mouth.
Topped with a Castiel getting pissy at Sam.
Totally gratuitous but he looks so lost and pleading.
Then there is the very much totally look of regret and sorrow in his face when he tries to take action against the boy.
In conclusion. NOT EVIL AND DOES NOT LOOK HAPPY ABOUT WHAT HE FEELS IS THE RIGHT THING TO DO.
Last but not least, I think he's feeling remorse here!
And as Dean would say, Yatzee! Castiel is NOT emotionless. He is very much an emotional being, and seriously, Misha's performance is so incredibly nuanced.
