Oliver Phelps: George Weasley
Fred Weasley : Look everyone, it's the heir of Slytherin!
George Weasley : Be careful! He's a seriously evil wizard.
Ron : Come on, Harry. Fred and George were just having a laugh.
Harry : They're the only ones.
Ron : Okay, so half the school thinks you're nipping off to the Chamber of Secrets every night. Who cares?
Harry : Maybe they're right.
Hermione : Harry! Harry? Oh, come on!
Harry : Look, I didn't know I could speak Parseltongue! What else don't I know about myself? Look. Maybe you can do something, even something horrible and not know you did it.
Hermione : You don't believe that, Harry. I know you don't. And if it makes you feel any better, Malfoy's staying for the holidays, too.
Ron : Why would that make anyone feel any better?
Hermione : Because, in a few days the Polyjuice Potion will be ready! In a few days, we may truly know who is the heir of Slytherin.
