Dean Cas! (hugs him) Man, You've no idea how good it is to see you again.
Cas Dean...? (peers closer and then blinks rapidly, as if in recognition) You're Dean. This is... this is you. Dean.
Dean Cas, you okay? You're not scrambled in the noggin again, are you?
Cas I'm not - my "noggin" isn't "scrambled". I just - I never knew you looked like this.
Dean Cas, you've seen me on many occasions for the past four years. Don't tell me you don't know what I looked like. Last I checked, you have working eyes. (suddenly worried) Your eyes are fine, right?
Cas My eyes are fine, Dean. But... this is new. (fingers reach up to brush over Dean's features)
Dean (a little uncomfortable but not shying away) Cas?
Cas (fingers still gently touching Dean's face) I used to see your soul only. It was easy to see you then, I can - could - see you anywhere in a room. Bright, warm, pure, painful sometimes, and so much guilt and regret, and so much good. I never knew you looked like this. I feel like...
Dean Like what, Cas?
Cas I don't know. Like I know you and yet I don't know you at the same time. (fingers slowly drop) Hello, Dean.
