These are her confessions
In “Denial, Anger, Acceptance,” a third-season “Dallas” episode, Sue Ellen (Linda Gray), clad in a robe, enters the hospital waiting room. Bobby (Patrick Duffy), Ann (Brenda Strong) and Christopher (Jesse Metcalfe) see her and stand.
SUE ELLEN: I started the fire. [Bobby’s face drops]
ANN: [Stunned] What?
SUE ELLEN: I was drunk, and I came down to get more to drink. And then I remembered that John Ross had a bottle in his room. And I saw their wedding invitation, and I lit it on fire. And then I passed out. [Crying] I am so sorry I lied to all of you. [Looks at each of them] I’m an alcoholic — and I will be, until I die. [Sobs as Ann embraces her]

Why would you do that to yourself I lost two Aunts that way not only that they both had cancer i remember that Bobby helped you on the Orginal show don’t do it to yourself
Great scene!
Linda Gray was great, as always. Script and storyline no so much.
I would really enjoy seeing Sue Ellen back on top! She took her punches with John Ross being a goofball husband, losing the election for Texas Governor, and of course what got her drinking again, JR passing away. Linda Gray is the best and I do not like to see Sue Ellen so miserable.
Enough with Drunk Sue Ellen. We want to see Strong Sue Ellen back. Maybe when the truth comes out about “J.R.’s Masterpiece,” Sue Ellen will find her backbone again.
No need to upset Miss Texas here. She’s trying & losing her alcoholic battle with its demonic addiction. Lets help her get sober so she can help the Ewings put the smackdown on Cliff Barnes’s proxy, Elena, & that god damned Barnes wife of John Ross’s.
