A scene from “Unfinished Business”

Queen Elizabeth II: I'm not sure what I was expecting. Each of his predecessors, Churchill, Eden, Macmillan, even Alec, each in their own way was formidable. Statesmanlike. But Wilson is neither old nor young, tall nor short, loud nor quiet, warm nor cold. He seems to have come from nowhere and is entirely unremarkable.

Princess Alice, Duchess of Gloucester: Best qualities in a spy.

Queen Elizabeth II: What did you say?

Princess Alice, Duchess of Gloucester: Aren't those the best qualities in a spy? Well, to be forgettable, unremarkable. Not stand out in a crowd. We used to say that about Henry, didn't we, dear?

Prince Henry, Duke of Gloucester: What?

Princess Alice, Duchess of Gloucester: That you would have made the perfect spy, because no one could remember having met you.

Prince Henry, Duke of Gloucester: I ... I'd say that was marginally better than everyone having nightmares having met you!
