Lestat: It's so easy you almost feel sorry for them. You'll get used to killing. Just forget about that mortal coil. You'll become accustomed to it, all too quickly.
Lestat: Claudia. You've been a very, very naughty little girl.
Lestat: For you, Louis. You can pretend it's wine.
Lestat: Oh Louis, Louis. Still whining, Louis. Have you heard enough? I've had to listen to that for centuries.
Louis: They know about us. They watch us dine on empty plates and drink from empty glasses.
Louis: Then out of curiosity, boredom, who knows what, I left the old world and came back to my America. And there, a mechanical wonder allowed me to see the sun rise for the first time in two hundred years. And what sunrises, seen as the human eye could never see them: silver at first, then, as the years progressed, in tones of purple, red, and my long lost blue.
Claudia: I came to make peace with you, even though you are the father of lies.
Lestat: Should we put out the light? And then put out the light. But once put out thy light, I cannot give it vital breath again. It needs must wither.
Lestat: Enough! Enough! Stop.
Claudia: I want some more.
Santiago: But hark, methinks a mortal doth approach.
Lestat: We are predators, whose all-seeing eyes were meant to give them detachment.
Louis: Blood, I was to find, was a necessity as well. I woke the next evening with a hunger I had never felt.
Louis: I'm flesh and blood, but not human. I haven't been human for two hundred years.
Claudia: It's time we were on our way. I'm hungry, and the city awaits.
Lestat: I am afraid, madam, my days are sacrosanct.
Claudia: Who will take care of me, my love, my dark angel, when you are gone?
Louis: Vampires pretending to be humans, pretending to be vampires.
Claudia: How avant-garde.
Answer: Lestat was quite vain; his disfigurement was most likely the reason he stayed hidden as long as he did. Also, his true age is uncertain, so 100 years could be an insignificant amount of time to him.
