Buffy the Vampire Slayer, Season 7

The First (as Buffy):
I envy them. Isn't that the strangest thing?

Caleb:
Well, it does throw me just a tad. I mean, they're barely more than animals. Feedin' off each other's flesh, it's nauseatin'. But you, you're everywhere. You're in the hearts of little children. You're in the souls of the rich. You're the fire that makes people kill and hate. The fire that will cure the world of weakness. They're just sinners. You are sin.

The First (as Buffy):
I do enjoy your sermons.

Caleb:
And you're in me. Gave me strength no man can have.

The First (as Buffy):
You're the only man strong enough to BE my vessel and I know you feel me, but... I know why they grab at each other. To feel. I want to feel. I want to wrap my hands around some innocent neck and feel it crack.

Caleb:
Amen.
