[At the end of the episode, we find Don watching a movie and drinking a beer in his apartment, alone in the dark. There's a knock at his door]
Charlie Eppes: Don?
Don Eppes: Charlie? You all right?
[Don goes to open the door, concerned, to find his brother holding a cardboard box - apparently the same one Don was looking for earlier containing things from Don's time in Albuquerque - nervously]
Charlie Eppes: Hey. I uh, found this box. I thought I'd...
[He walks in]
Don Eppes: What, bring it over at two in the morning? What did you do? You opened it?
[He takes the box from Charlie and goes back to his chair]
Don Eppes: What is with you man? Even when we were kids, you were always going through my stuff.
Charlie Eppes: You always had cool stuff.
[Charlie stays back, watching his brother as he pulls an envelope from the box addressed to Don at his L.A. address]
Charlie Eppes: Seems like you left a lot of good friends back there, huh?
Don Eppes: Yeah, well.
[He takes a shaky breath]
Don Eppes: Family first, right?
Charlie Eppes: [softly] Right.
[Don takes a diamond engagement ring from the envelope, turns it in the light, then glances back at Charlie, who looks at the floor. He sighs]
Don Eppes: Look. I was gonna tell you, I just... I don't know. I mean, we were in two different worlds. You know how it is. And mom got sick, and I don't know.
[He looks at a snapshot of himself and Kim looking happy and in love]
Charlie Eppes: I understand.
Don Eppes: Yeah?
[They exchange a look]
Charlie Eppes: Yeah. I agree. We're from... uh, from two different worlds.
[He looks at the floor again]
Don Eppes: Well, not so much lately.
[He laughs]
Don Eppes: See me all the time now.
Charlie Eppes: Yeah.
[He looks up and nods, smiling]
Charlie Eppes: I've learned a lot from you, actually.
Don Eppes: Thanks.
[Don grins and Charlie shifts nervously, still unsure, so Don shifts gears]
Don Eppes: You want to watch the rest of the movie?
Charlie Eppes: Okay. Sure.
[He finally comes into the living room and sits down]
Don Eppes: It's a great flick. It's about baseball.
Charlie Eppes: The most statistically-driven sport in the world.
[Don offers him a beer, then chips, and Charlie just smiles and declines, and the two watch the movie in companionable silence]
