I 사랑 cass I think he is really funny too. BUT

당신 know, I was having this conversation with my Mom when we watched the sneak peek about how Cas always leaves mid-conversation and we agreed it would annoy the crap out of us. Heck, I still 사랑 him to death, but there would be some curse words yelled at loud volumes that I'm sure he would hear coming from me ;)

I'd be kinda happy if Cas popped up somewhere around me, because that would mean that Sam and Dean would be nearby...

I 사랑 Castiel to death but if he was doing that to be contently i think i would get pissed. And yes i would deff be cussing at mid air after he left
