SAM: All right, come on. We don’t have much time. As soon as the flare’s out, they’ll be back.
DEAN: Wait, wait
. Sam, wait. Dad, you can’t come with us.
SAM: What? What are you talkin’ about?
SAM: Dean, we should stick together. We’ll go after those demons—
DEAN: Sam! Listen to me! We almost got Dad killed in there. Don’t you understand? They’re not gonna stop
, they’re gonna try again. They’re gonna use us to get to him. I mean, Meg was right. Dad’s vulnerable when he’s with us. He’s—he’s stronger without us around.
, no. (He puts a hand on his father’s shoulder. DEAN watches sadly.) After everything , after all the time we spent lookin’ for you—please. I gotta be a part of this fight.
JOHN: Sammy, this fight is just starting. And we are all gonna have a part to play. For now, you’ve got to trust me, son. Okay, you’ve gotta let me go. (All three of them are silent for a moment, close to tears. Finally, SAM pats his father’s shoulder once, then lets go. JOHN and DEAN share a look, then JOHN walks to his truck. Once there, he looks back at them one more time.) Be careful, boys. (He gets in his truck and drives away.)
