Sister’s keeper
In “My Brother’s Keeper,” a seventh-season “Dallas” episode, Cliff and Pam (Ken Kercheval, Victoria Principal) walk down a busy street together.
CLIFF: I tell you, there is nothing better than some good Mexican food to clear the cobwebs out of your hair.
PAM: Ugh. Just the thought of Mexican food right now is enough to make me sick. What I need is some more sleep. Do you know what time Christopher got me up?
CLIFF: You’re healthy. You don’t need anymore sleep. I think there’s a pretty good Chinese restaurant right around this corner.
PAM: Well, there’s a coffee shop just down the block.
CLIFF: You can’t exist just on coffee.
PAM: So I’ll have some toast. Since when are you so concerned about what I eat?
CLIFF: I’m not concerned about what you eat. I’m more worried about you right now.
PAM: You really are.
CLIFF: Yeah. And I tell you, I’m gonna be the one to pick you up and drive you to court tomorrow.
PAM: [Laughs] Why? Are you afraid I’ll change my mind?
CLIFF: No, except I know that you’re hurting right now, and I don’t want you to be alone. [They stop and face each other. He holds her arms.] Believe it or not, I understand how much you love Bobby. And tomorrow is going to be a rough day, and I want to be with you.
PAM: You know, whatever else has gone wrong for me these past few years, it’s wonderful to have my brother back.
They lean in to each other and smile.
