Prince Charles: I have done my best, my very best. And I am suffering.
Queen Elizabeth II: No, you are not suffering. We're all suffering, having to put up with this. Let me make something clear. When people look at you and Diana, they see two privileged young people, who through good fortune have ended up with everything one could dream of in life. No one, not a single breathing living soul anywhere, sees cause for suffering.
Prince Charles: They would if they knew.
Queen Elizabeth II: Knew what? They know that you betray your wife and make no attempt to hide it. They know that thanks to you, she has psychological problems and eats or doesn't eat, or whatever it is she does or doesn't do. They know that you are a spoilt, immature man, endlessly complaining unnecessarily, married to a spoilt, immature woman, endlessly complaining unnecessarily. And we are all heartily sick of it. All anyone wants is for the pair of you to pull yourselves together, stop making spectacles of yourselves, and make this marriage and your enormously privileged positions in life work.
Prince Charles: And if I want to separate...
Queen Elizabeth II: You will NOT separate or divorce or let the side down in any way and if one day, you'd expect to be king...
Prince Charles: I do.
Queen Elizabeth II: Then might I suggest you start to behave like one!
