No stairway to heaven
In “Things Ain’t Goin’ Too Good at Southfork,” a sixth-season “Dallas” episode, J.R. (Larry Hagman) enters Southfork and heads toward the stairs, unaware a drunken Sue Ellen (Linda Gray) is waiting for him in the living room.
SUE ELLEN: You bastard! You finally came home. [Sips from her glass, pours another]
J.R.: You’ve decided to come back to Southfork, I’m happy to see. [Enters the living room, sets his car keys on a table]
SUE ELLEN: [Glares at him] Not because I wanted to.
J.R.: I was so worried about you, Sue Ellen.
SUE ELLEN: When were you the most worried? Before or after you made love to Holly Harwood?
J.R.: Sue Ellen, just because you may have seen my car in front of her house doesn’t mean anything happened.
SUE ELLEN: [Guffaws] Your car? You think this has anything to do with your car? I saw you and Holly in bed.
J.R.: You couldn’t have.
SUE ELLEN: Why not, because you didn’t see me? No, because you were too damn busy doing other things to see anything. [Begins to cry]
J.R.: [Steps forward] Sue Ellen, don’t fly off the handle. I can explain all of this.
SUE ELLEN: [Swats at him] Don’t you touch me!
J.R.: Darlin’. …
She tosses her drink in his face, grabs his keys and runs out of the room as Miss Ellie (Barbara Bel Geddes) comes down the stairs.
ELLIE: Sue Ellen!
J.R.: [Rushing into the foyer] Sue Ellen!
ELLIE: Well, you’ve destroyed her again. Don’t you ever learn?
Dallas Decoder 
What exactly is wrong with John Ross Ewing the IInd cheating on Sue Ellen with Holly Harwood? He had to orchestrate a deal, so a little romp was needed. He’s J. R., even Jock Ewing Senior strayed & he wound up producing brother Ray Krebbs & Miss elly forgave him b/c it was WW2. Why can’t she & understand that brother J. R. is more than human, he’s the spawn of the master who created the Ewing Oil Company Limited of Dallas, Texas.
R.J., I’m sure J.R. appreciates your support!
