Supernatural, Season 4

Castiel:
You asked to see me.

Dean:
Yeah, listen, I, uh, I need something.

Castiel:
Anything you wish.

Dean:
I need you to take me to see Sam.

Castiel:
Why?

Dean:
There's something I gotta talk to him about.

Castiel:
What's that?

Dean:
... The BM I took this morning, what's it to you? Just make it snappy.

Castiel:
I don't think that's wise.

Dean:
Well, I didn't ask you for your opinion.

Castiel:
Have you forgotten what happened the last time you met?

Dean:
No. That's the whole point. Listen, I'm gonna do whatever you mooks want, okay? I just need to tie up this one thing; five minutes, that's all I need.

Castiel:
... No.

Dean:
... What do you mean "no"? Are you saying that I'm trapped here?

Castiel:
You can go wherever you want.

Dean:
Super, I wanna go see Sam.

Castiel:
Except there.

Dean:
I wanna take a walk.

Castiel:
Fine, I'll go with you.

Dean:
Alone.

Castiel:
No.

Dean:
... You know what, screw this noise; I'm outta here.

Castiel:
Through what door?
