DOCTOR (to the WOMAN). He must be blind.
WOMAN. Yes. I think he is.
STRANGER. No. I can see you; but I can't see the lights.
DOCTOR. For you it's growing dark.... You've played with the lightning, and looked too long at the sun. That is forbidden to men.
STRANGER. We're born with the desire to do it; but may not. That's Envy....
DOCTOR. What do you possess that's worthy of envy?
STRANGER. Something you'll never understand, and that only I can value.
DOCTOR. You mean, the child?
MANGER. You know I didn't mean it. If I had I'd have said that I possessed something you could never let.
DOCTOR. So you're back at that! Then I'll express myself as clearly: you took what I'd done with.
