In “Battle Lines,” an eighth-season “Dallas” episode, J.R. (Larry Hagman) stands over John Ross (Omri Katz), who is cleaning his bike on the Southfork patio.
JOHN ROSS: Are you going to see Uncle Bobby at the hospital?
J.R.: Well, I might drop in on him this afternoon. [Looks at his watch] I’ve got an awful lot of work to do at the office.
Sue Ellen (Linda Gray) exits the house and stands on the patio, listening.
JOHN ROSS: Maybe I can go to the office and help you.
J.R.: [Chuckles] Well, that’s a good idea. Maybe we ought to wait until you’re a little older, though, huh?
JOHN ROSS: Daddy are you going to be running Ewing Oil all by yourself?
J.R.: Well, I’m just going to run it until Bobby gets back. Why do you ask that?
JOHN ROSS: Well, you said you were going to run the company all by yourself some day and then give it to me.
J.R.: Well, I couldn’t take it away from Bobby while he’s in the hospital.
JOHN ROSS: But Mama said Bobby can’t see right now.
J.R.: [Sits in a patio chair] John Ross, there’s something I want to explain to you, son. One of these days I expect to control all of Ewing Oil, and Bobby won’t work there. He’ll be doing something else. But I want you to remember that he’s my brother — and I love him very much. And it just wouldn’t be fair to take advantage of him while he’s sick. That’s just something you don’t do to people you love. But when he’s well — and able to defend his shares in Ewing Oil — well, I’m going to fight for it. And of course I’ll win. Then I’m going to give you the whole company — and you’ll never have to share it with anybody. Now you understand that?
JOHN ROSS: I think so.
J.R.: Good. And you’ve got to remember: With family, you play fair. Because there are rules to follow. And if you do, you’ll be able to live with yourself.
