JOHN
No, Mary. I only want to catch that train. I'm content with the rest. The same things must happen, and they must lead me the same way, to you, Mary. Good night, now, dear.
MARY
Good night?
JOHN
I shall stay here on the sofa holding the crystal and thinking. Then I'll have a biscuit and start at seven.
MARY
Thinking, John? What about?
JOHN
Getting it clear in my mind what I want to do. That one thing and the rest the same. There must be no mistakes.
