Ruth:
Angela believes that Princess Diana was murdered by the British Security Services. By us. [Jo laughs]

Angela:
What's funny?

Jo:
Nothing.

Angela:
You find that funny?

Jo:
No.

Angela:
Funny? That your boss was on a committee that ordered the faking of the car accident which killed Diana?

Harry:
Angela, what are you talking about?

Angela:
I'm talking about you being chair of the contingent events committee.

Harry:
The what?

Angela:
The committee that organized, then ordered the assassination.

Harry:
This is madness.

Angela:
You can't deny there was such a committee.

Harry:
I can. Angela, you must let us help you.
