That’s that, Jock
In “No More Mr. Nice Guy, Part 1,” “Dallas’s” fourth-season opener, Miss Ellie and Jock (Barbara Bel Geddes, Jim Davis) talk while leaving Dallas Memorial Hospital.
ELLIE: Jock, now that Bobby’s back, you’ve got to find a way to keep him here.
JOCK: I don’t know how. He was mad as hell at me when he left.
ELLIE: Well, that was because he felt you’d given him a job to do and then you didn’t stand behind him.
JOCK: Well, I couldn’t. When he opened Ewing 23, he made Cliff Barnes a partner in the profits. After what that man’s done to us, no way.
ELLIE: Does Ewing Oil have to cost us another son? Jock, I know how important the company is to you, but I’ve lost Gary and now, unless you stop him, Bobby will leave again.
JOCK: Ewing Oil has been my life, Ellie.
ELLIE: And J.R. may be dying because of it. [Jock puts his hand on her shoulder.] I don’t think the company is worth my family. I want Bobby home, no matter what it costs Ewing Oil.
