Supernatural, Season 6

Tortured Sam:
I wish you hadn't come, Sam.

Sam:
I had to. I'm here, right? Out there in the real world, I'm at Bobby's, aren't I?

Tortured Sam:
How do you know?

Sam:
This whole time, I've smelled nothing but Old Spice and whiskey. Figured if I could get back here, back to my body I could, I don't know, I could snap out of it somehow.

Tortured Sam:
First you have to go through me.

Sam:
Why?

Tortured Sam:
Humpty-dumpty has to put himself back together again before you wake up. And I'm the last piece.

Sam:
Which means I have to know what you know. What happened in the cage?

Tortured Sam:
Trust me. You don't want to know it.

Sam:
You're right. But I still have to

Tortured Sam:
Sam, you can't imagine... Stay here. Go back, find that bartender, go find Jess, but don't do this. I know you. You're not strong enough.

Sam:
We'll just have to see

Tortured Sam:
Why is this so important to you?

Sam:
You know me. You know why. I'm not leaving my brother alone out there.

Tortured Sam:
(picks up a knife and holds it out to Sam) I'm not gonna fight you. But this is your last chance. (Sam takes the knife.) Good luck. You're gonna need it. (Sam stabs him, absorbing his memories.)
