-->'''Knox:''' Supposing I said that I'm mortally ill, and that I've only a year or so to live. Supposing I'd broken down and wept. Supposing I'd opened my heart to you, and said that I have no wish to die; that I am frightened and in despair. ''[laughs]'' Well, I can't believe that you'd welcome such a disclosure, finding it distressing, and embarrassing--somewhat inconsiderate. And so, having regard for your feelings as well as my own, it would seem to be both correct and appropriate to...moderate my response.
-->'''Turing:''' ''[quietly]'' Are you dying? ''[Knox ignores the question[[note]]Dilly Knox died in 1943 of lymph cancer[[/note]]]''
