A scene from “Unfinished Business”

Queen Elizabeth II: Ask yourself, in the time I've been on the throne, what have I actually achieved?

Princess Margaret: You've been calm and stable and...

Queen Elizabeth II: Useless and unhelpful. This country was still great when I came to the throne, and now look. So much for the Second Elizabethan Age, which Winston talked about. All that's happened on my watch is the place has fallen apart.

Princess Margaret: It's only fallen apart if we say it has. That's the thing about the monarchy. We paper over the cracks. And if what we do is loud and grand and confident enough, no one will notice that all around us it's fallen apart. That's the point of us. Not us. Of you. You cannot flinch. Because if you show a single crack, we'll see it isn't a crack, but a chasm, and we'll all fall in. So you must hold it all together.

Queen Elizabeth II: Must I do that alone?

Princess Margaret: There is only one queen.
