Oh and just because...here's the Something Wicked exchange.

""""""JOHN: All right. You know the drill, Dean. If anybody calls, you don’t pick up. If it’s me, I’ll ring once and then call back. You got that?

YOUNG DEAN: Mmhmm. Don’t answer the phone unless it rings once first.

JOHN: Come on, dude, look alive. This stuff’s important.

YOUNG DEAN: I know, it’s just—we’ve gone over it, like, a million times, and you know I’m not stupid.

JOHN: I know you’re not. But it only takes one mistake, you got that? (DEAN nods.) All right, if I’m not back Sunday night?

YOUNG DEAN: Call Pastor Jim.

JOHN: Lock the doors and windows, close the shades, and most important—

YOUNG DEAN: Watch out for Sammy. (He looks at YOUNG SAM, who is watching television.) I know.

JOHN: All right, if somethin’ tries to bust in?

YOUNG DEAN: Shoot first, ask questions later. (JOHN puts a hand on his son’s shoulder.)

JOHN: That’s my man. (He leaves the motel room. DEAN shuts the door behind him and locks it. He continues to watch SAM.)"""""


Dean is being treated with responsibility here reflected in the language...
