Supernatural, Season 3

Sam:
Drop the attitude, Dean. Quit turning everything into a punchline. And you know something else? Stop trying to act like you're not afraid.

Dean:
I'm not!

Sam:
You're lying. And you may as well drop it cause I can see right through you.

Dean:
You got no idea what you're talking about.

Sam:
Yeah, I do. You're scared Dean. You're scared because your year is running out and you're still going to hell, and you're freaked.

Dean:
And how do you know that?

Sam:
Because I know you!

Dean:
Really?

Sam:
Yeah, because I've been following you around my entire life! I mean, I've been looking up to you since I was four, Dean. Studying you, trying to be just like my big brother. So yeah, I know you. Better that anyone else in the entire world. And this... is exactly how you act when you're terrified. And I mean, I can't blame you. It's just...

Dean:
What?

Sam:
It's just I wish you would drop the show and be my brother again. Cause... just cause.
