Dean Winchester: I'm so proud of you, Sam. You know that? I've always looked up to you. Man, when we were kids, you were so damn smar... smart. You never... You never took any of dad's crap. I never knew how you did that. And you're stronger than me. You always have been. Hey, did I ever tell you... Did I ever tell you that night that, uh... that I ca... That I came for you when you were at school? You know, when dad hadn't come back from his hunting trip?

Sam Winchester: Yeah, um... Uh, the Woman in White.

Dean Winchester: The Woman in White. That's right. I must have stood outside your dorm for hours... because I didn't... I didn't know what... What you would say. I thought you'd tell me to... to get lost or get dead. And I don't know what I would've done... if I didn't have you. 'Cause I was so scared. I was scared, 'cause when it all came down to it, it was always you and me. It's always been you... and me.

Sam Winchester: Then don't leave me.
