A scene from “Unfinished Business”

Prince Charles: It's always been hard for us to understand the connection that Diana has with people, but the fact that it's inexplicable shouldn't lead us to deny it. I've just been out there. I've seen it for myself. People taking to the streets. Not just here, all over the world, in their hundreds, thousands. And they will expect us to show grief and compassion and for you to be mother to the nation.

Queen Elizabeth II: If you don't mind, I'm concerned with being a grandmother to William and Harry. That's my priority. And I'd rather not be lectured on how or when to grieve or show emotion.

Prince Philip: Particularly by the person who caused her the most pain.

Prince Charles: All right. All right. I admit, I let her down in life. But I will not let her down in death. We can't have it both ways. Haven't we learnt that yet? We can't be a private family when we want to be and a public one when it suits us. Time and time again, we try to have it both ways. We can't, and it's time William learnt that. Yes, he's a shy boy, but he's also a future king. And when his mother dies and people grieve, he has to behave like one.
