Buffy: How could you be so stupid? You never leave anyone alive, you have to finish them off.
Sorority Girl: Or turn them by making them drink your blood. Oh, that guy Carlos saw you.
Lana: His name's Clark.
Buffy: Oh, whatever. He saw you feeding and he was sneaking around my room. That's two strikes. I'm not waiting for a third.
Lana: He's my boyfriend.
Buffy: So? Lana, you're going to live forever now. He's going to get old and withered and sag in places you don't want to see sagging. You're special, he's not. Deal.
