I love the difference between this Cas and the Cas we have now. Like when Misha first started on the show I think he did such an amazing job of portraying something alien inhabiting a human container. Like back in seasons 4/5/6 whenever Cas talks or moves it looks like he is having to make a conscious effort to remember to at least try to look a little bit human.
Like in the second gif here - and we see it a lot in the first few seasons - Cas starts to talk and then remembers you’re supposed to look at people when you talk to them - and he doesn’t always remember to do that, something he just keep on talking to the air in front of him - so he turns his head and then it looks like a split second later he’s like, “Oh, right, the eyes, gotta move the eyes too.” so his gaze turns to Dean but it’s a fraction delayed from the movement of his head.
I dunno, I always noticed that about early Cas but it’s bled away now, he’s more comfortable in his body and moves more naturally.
