Argus Filch: A pity they let the old punishments die. There was a time detention would find you hanging by your thumbs in the dungeons. God, I miss the screaming.
Hermione Granger: I had you looking in the wrong section. How could I be so stupid? (throws a giant book on the table) I checked this out weeks ago for a bit of light reading.
Ron Weasley: This is light?
Hermione Granger: You can help Harry, then. He's going to go and look in the library for information on Nicholas Flamel.
Ron Weasley: We've looked a hundred times!
Hermione Granger: Not in the restricted section. Happy Christmas.
Ron Weasley (to Harry): I think we've had a bad influence on her.
Rubeus Hagrid: Now, you listen to me, all three of you. You're meddling in things that ought not to be meddled in. It's dangerous. What that dog is guarding is strictly between Professor Dumbledore and Nicholas Flamel.
Harry Potter: Nicholas Flamel?
Rubeus Hagrid: I shouldn't have said that. I should not have said that...
Harry Potter: I don't know, Sir.
Severus Snape: Pity. Clearly, fame isn't everything... is it, Mr. Potter?
Harry Potter: Clearly, Hermione knows. Seems a pity not to ask her.
Minerva McGonagall: Perhaps, it'd be more useful if I were to transfigure Mr. Potter and yourself into a pocket-watch. That way, one of you might be on time.
Harry Potter: We got lost.
Minerva McGonagall: Then perhaps a map? I trust you don't need one to find your seats.
Draco Malfoy: This is Crabbe, and Goyle. And I'm Malfoy. Draco Malfoy. (Ron snickers) Think my name's funny, do you? I've no need to ask yours. Red hair and a hand-me-down robe? You must be a Weasley. We'll soon find out that some wizarding families are better than others, Potter. You don't want to go making friends with the wrong sort. I can help you there. (Draco extends a hand towards Harry, Harry doesn't shake it)
Harry Potter: I think I can tell the wrong sort for myself, thanks.
Harry Potter: He killed my parents, didn't he? The one who gave me this. You know, Hagrid. I know you do.
Rubeus Hagrid: First, and understand this Harry because it's very important: Not all wizards are good. Some of them go bad. A few years ago... there was a one wizard who went as bad as he can go. His name was V... His name was V...
Harry Potter: Maybe if you wrote it down?
Rubeus Hagrid: No, I can't spell it. All right, Voldemort.
Harry Potter: Voldemort?
Rubeus Hagrid: It was dark times, Harry. Dark times. Voldemort started to gather some followers. Brought them over to the Dark Side. Anyone that stood up to him ended up dead. Your parents fought against him. But nobody lived once he decided to kill them. Nobody, not one. Except you.
Garrick Ollivander: Curious. Very curious.
Harry Potter: Sorry, but what's curious?
Garrick Ollivander: I remember every wand I've ever sold, Mr. Potter. It so happens that the phoenix... whose tail feather resides in your wand, gave another feather. Just one other. It is curious that you should be destined for this wand... when its brother gave you that scar.
Harry Potter: And who owned that wand?
Garrick Ollivander: We do not speak his name. The wand chooses the wizard, Mr. Potter. It's not always clear why. But I think it is clear... that we can expect great things from you. After all, He-Who-Must-Not-Be-Named... did great things. Terrible... yes, but great.
Harry Potter: You knew? You knew all along and you never told me?
Petunia Dursley: Of course we knew. How could you not be? My perfect sister being who she was. My mother and father were so proud the day she got her letter. "We have a witch in the family. Isn't it wonderful?" I was the only one to see her for what she was. A freak! Then she met that Potter, and then she had you... and I knew you would be the same. Just as strange, just as... abnormal. And then, if you please, she went and got herself blown up! And we got landed with you.
