Supernatural, Season 9

[Young Dean is fastening a tie.]

Sonny:
Oh, look at you. You clean up good!

Young Dean:
Thank you. You know, uh ... I've never actually been to one of these school dances before.

Sonny:
Yeah. Look, about that, Dean, your old man's outside … and, man, he's really something. I tried to tell him what a big night it was for you, Dean, and ask him if he could come back later, but he just said to tell you he had a job, said you'd know what that means.

[Young Dean tries to hold back tears.]

Sonny:
You know, after I got out of jail, this place gave me a second chance, and it's done the same for you, too.

[Young Dean nods.]

Sonny:
So if you want, I'll stick my neck out for you, and I'll fight for you to stay.

[John's car horn honks outside. Young Dean goes to the window to look, and sees a very young-looking Sam holding a spaceship out the window of the car. Young Dean laughs, choked-up, and turns back toward Sonny, holding out his hand. There's a tear trickling out his eye as they shake hands.]

Young Dean:
Sonny... thank you ... for everything. But I have to go.
