Buffy: My mom… said some things to me about being the Slayer. That it’s fruitless. No fruit for Buffy.
Angel: She’s wrong.
Buffy: Is she? Is Sunnydale any better than when I first came here? Okay, so I battle evil. But I don’t really win. The bad keeps coming back and getting stronger. Like that kid in the story, the boy that stuck his finger in the duck.
Angel: Dike. It’s another word for dam.
Buffy: Oh. Okay, that story makes a lot more sense now.
