Ginny : Hedwig. Mum?
Mother: Ginny, what is it?
Ginny: I was only wondering when Harry got here.
Mother: What? Harry? Harry who?
Ginny: Harry Potter, of course.
Mother: I think I'd know if Harry Potter was in my house, wouldn't I?
Ginny: His trunk's in the kitchen, and his owl.
Mother: No, dear, I seriously doubt that.
Ron: Harry? Did someone say "Harry"?
Ginny: Me, nosy. Is he up there with you?
Ron: Of course not. I'd know if my best friend was in my room, wouldn't I?
Ginny: Is that an owl?
Mother: You haven't seen him, have you?
Ginny: He's wandering about the house.
Mother: What a lovely surprise. Why didn't you let us know you were coming?
Harry: I didn't know. Dumbledore.
Mother: Oh, that man. But then, what would we do without him?
Ron: Got a bit of toothpaste.
Harry: So when did you get here?
Hermione: A few days ago. Though for a while, I wasn't sure I was coming.
Ron: Mum sort of lost it last week. Said Ginny and I had no business going back to Hogwarts. That it's too dangerous.
Harry: Oh, come on.
Hermione: She's not alone. Even my parents, and they're Muggles, know something bad's happening.
Ron: Anyway, Dad stepped in, told her she was being barmy, and it took a few days, but she came around. Harry: But this is Hogwarts we're talking about. It's Dumbledore. What could be safer?
Hermione: There's been a lot of talk recently that Dumbledore's got a bit old.
Harry: Rubbish! Well, he's only. What is he?
Ron: Hundred and fifty? Give or take a few years.
Bella: Cissy! You can't do this! He can't be trusted!
Narcissa: The Dark Lord trusts him.
Bella: The Dark Lord's mistaken.
Severus: Run along, Wormtail.
Narcissa: I know I ought not to be here. The Dark Lord himself forbade me to speak of this.
Severus: If the Dark Lord has forbidden it, you ought not to speak. Put it down, Bella. We mustn't touch what isn't ours. As it so happens, I'm aware of your situation, Narcissa.
Bella: The Dark Lord told you?
Severus: Your sister doubts me. Understandable. Over the years I've played my part well. So well, I've deceived one of the greatest wizards of all time. Dumbledore is a great wizard. Only a fool would question it.
Narcissa: I don't doubt you, Severus.
Bella: You should be honored, Cissy. As should Draco.
Narcissa: He's just a boy.
Severus: I can't change the Dark Lord's mind. But it might be possible for me to help Draco.
Narcissa: Severus. Swear to it.
Bella: Make the Unbreakable Vow. It's just empty words. He'll give it his best effort. But when it matters most...he'll just slither back into his hole. Coward.
Severus: Take out your wand.
