(In the bunker…)

Dean Winchester: I wonder what’s gonna happen to this place. After we’re gone, you think some hunter’ll move in, keep fightin’ the fight?

Sam Winchester: Yeah, I hope so.

Dean Winchester: Yeah. Me, too.

Sam Winchester: What are you doin’?

Dean Winchester: Leaving our mark.

(They carve out their initials on the table in the bunker, just as they did in the Baby when they were little.)
