Supernatural, Season 4

Sam (is cleaning a gun. Someone knocks on the door. He grabs a shotgun and opens the door, revealing Ruby possessing the coma girl. She holds up a piece of paper)

Ruby:
Proof. This body is 100% socially conscious. I recycle. Al Gore would be proud.

Sam:
You grabbed a coma patient?

Ruby:
You didn't want me to take a body with someone in it, and I made sure that the spirit was gone. Apartment was empty. You happy?

Sam:
Why are you here?

Ruby:
I can't bring Dean back. But I can get you something else that you want.

Sam:
And, uh... what's that?

Ruby:
Lilith.

Sam:
You want me to use my psychic whatever.

Ruby:
Look, I know that it spooks you...

Sam:
Skip the speech. I'm ready. Let's go.

Ruby:
Slow down there, cowboy.

Sa,:
Just tell me what I have to do.

Ruby:
Look, Lilith is one scary bitch. When I was in the Pit, there was talk. She's cooking up something big -- apocalyptic big.

Sam:
So let's kill her.

Ruby:
You want to go in there and half-ass it like before? We have the time to get it right. Let's get it right.

Sam:
Okay. What do you want from me?

Ruby:
Well, a little patience... and sobriety. Promise me that... and I will teach you everything I know.
