Lestat quoting Othello (Act 5, scene 2), in Interview with the Vampire (strike-throughs are words cut out, and the last line is different, too):
Yet she must die, else she’ll betray more men.
Put out the light, and then put out the light.
If I quench thee, thou flaming minister, I can again thy former light restore Should I repent me. But once put out thy light, Thou cunning’st pattern of excelling nature, I know not where is that Promethean heat That can thy light relume. When I have plucked thy rose
I cannot give it vital growth again,
Its needs must wither.”
