Supernatural, Season 1

Sam:
Dean, if this demon killed Mom and Jess, and Dad's closing in, we've gotta be there. We've gotta help.

Dean:
Dad doesn't want our help!

Sam:
I don't care.

Dean:
He's given us an order.

Sam:
[firmly] I don't care. We don't always have to do what he says.

Dean:
Sam, Dad is asking us to work jobs, to save lives, it's important.

Sam:
Alright, I understand, believe me, I understand. But I'm talking one week here, man, to get answers. To get revenge.

Dean:
All right, look, I know how you feel.

Sam:
Do you? [Dean seems shocked at Sam's tone] How old were you when Mom died? Four? Jess died six months ago. How the hell would you know how I feel?

Dean:
Dad said it wasn't safe. For any of us. I mean, he obviously knows something that we don't, so if he says to stay away, we stay away.

Sam:
I don't understand the blind faith you have in the man. I mean, it's like you don't even question him.

Dean:
Yeah, it's called being a good son!

[Sam gets out of the car and starts getting his stuff out of the trunk]

Dean:
You're a selfish bastard, you know that? You just do whatever you want. Don't care what anybody thinks.

Sam:
That's what you really think?

Dean:
Yes, it is.

Sam:
Well, then this selfish bastard is going to California.

Dean:
Come on, you're not serious.

Sam:
I am serious.

Dean:
It's the middle of the night! Hey, I'm taking off, I will leave your ass, you hear me?

Sam:
That's what I want you to do.

Dean:
Goodbye, Sam.
