* J.R. going through his emotional turmoil after confirming [[spoiler:Jock Ewing]]'s death.
* [[spoiler:Bobby Ewing]]'s death, even if it did [[TropeCodifier codify]] [[spoiler:AllJustADream]].
** While everyone else had the usual emotions, J.R.'s expressions were priceless, and solidly in the "this can't be happening" range.
-->'''J.R.:''' Don't do this to me, [[spoiler:Bobby]]. Don't leave me.
** And him that night taking it out on Sue Ellen, who was out and about during [[spoiler:Bobby]]'s death and didn't find out until right then. [[MenDontCry J.R. spends the entirety of the Season 8/9 premiere trying not to break down]], [[ManlyTears only letting go when he's alone]] with [[spoiler:Bobby]]'s coffin right after his funeral.
** Also Pam blaming herself afterward.
* In 2012's "Revelations", J.R. to an unconscious and critically ill Bobby:
-->'''J.R.:''' Come on, wake up, you hear me? Wake up and you get better. And you keep fighting. You keep fighting me! Now I'm gonna tell you something you never heard me say before: I love you Bobby, and I don't know who I'd be without you.
* Bobby breaking down and crying after [[spoiler:J.R.]]'s funeral.
** Just [[spoiler:J.R.]]'s funeral in general.
* Pambecca miscarrying her twins. Cliff's move of ordering the explosion on the rig, even after finding out she was on there, definitely means he's crossed the MoralEventHorizon
* Six words: "I shot your father, John Ross."
* This, for John Ross, after Sue Ellen wrongly suspects him of sleeping with his secretary Candice, and later lashes out at him [[spoiler:,while drunk, no less]].
---> '''Sue Ellen''': Once a cheater, always a cheater. I should have learned that lesson the first time around.
---> '''John Ross''': You donít know what youíre talking about, Mama. Yeah, yeah, Candace was in my office and the crazy bitch was all over me. And I turned her down!
---> '''Sue Ellen''': BULLSHIT! I know what I saw!
---> '''John Ross''': You donít know, because youíre drunk! I am telling you the truth!
---> '''Sue Ellen''': Even drunk, I know the sound of a lie, and you are an expert at it, just like your father.
---> '''John Ross''': I AM NOT MY FATHER!!! Are you so hell-bent on punishing J.R. for his sins that youíre willing to destroy the relationship with your only son? Damn it, I need you Mom, and you sided with them. Iím your son. You remember that? Or are you too damn addled to remember who I am? [Reaches for the bottle, holds it up] Why are you doing this to yourself again, huh?
---> '''Sue Ellen''': [Sobbing] Donít you get it? You did this to me. You and your father.
---> '''John Ross''': No, Mama. You did this to yourself. Youíre so busy seeing the ghost of J.R. in me that you cannot stop to take a hard look in the damn mirror. You want me to take responsibility for my actions? Then you take responsibility for yours. [Walks away, leaves the house, slams the door behind him]
