Harry Potter: You're the Grey Lady. The Ghost of Ravenclaw Tower.

Helena Ravenclaw: I do not answer to that name.

Harry Potter: No, I'm sorry. I'm sorry. It's Helena, isn't it? Helena Ravenclaw. Rowena's daughter.

Helena Ravenclaw: Are you a friend of Luna's?

Harry Potter: Yes. And she thought you might be able to help me.

Helena Ravenclaw: You seek my mother's diadem.

Harry Potter: Yes. That's right.

Helena Ravenclaw: Luna is kind, unlike so many of the others. But she was wrong. I cannot help you.

Harry Potter: Wait! Please! I want to destroy it.
