Lucius Malfoy: Your parents were meddlesome fools too. Mark my words, Potter. One day soon... you are going to meet the same sticky end.
Lucius Malfoy: Who was it?
Albus Dumbledore: Voldemort.
Lucius Malfoy: Ah.
Albus Dumbledore: Only this time he chose to act through somebody else... by means of this.
Lucius Malfoy: I see.
Albus Dumbledore: Fortunately, our young Mr. Potter discovered it. One hopes that no more of Lord Voldemort's old school-things... should find their way into innocent hands. The consequences for the one responsible would be... severe.
Lucius Malfoy: Well, let us hope... that Mr. Potter will always be around to save the day.
Harry Potter: Don't worry. I will be.
Harry Potter: I couldn't help but notice certain things, certain... Certain similarities between Tom Riddle and me.
Albus Dumbledore: I see. Well, you can speak Parseltongue, Harry. Why? Because Lord Voldemort can speak Parseltongue. If I'm not mistaken, Harry... he transferred some of his powers to you... the night he gave you that scar.
Harry Potter: Voldemort transferred some of his powers to me?
Albus Dumbledore: Uh-huh. Not intentionally... but yes.
Harry Potter: So the Sorting Hat was right. I should be in Slytherin.
Albus Dumbledore: It's true. You possess many of the qualities that Voldemort himself prizes. Determination, resourcefulness... and if I may say so, a certain disregard for the rules. Why, then, did the Sorting Hat place you in Gryffindor?
Harry Potter: Because I asked it to.
Albus Dumbledore: Exactly, Harry. Exactly. Which makes you different from Voldemort. It is not our abilities that show what we truly are. It is our choices. If you want proof why you belong in Gryffindor... then I suggest you look more closely at this. (hands him The Sword of Gryffindor) Be careful.
Harry Potter (reads the inscription on the sword): Godric Gryffindor.
Albus Dumbledore: It would take a true Gryffindor to pull that out of the hat.
Harry Potter: Fawkes?
Tom Riddle: So this is what Dumbledore sends his great defender. A songbird and an old hat.
Harry Potter: Albus Dumbledore is the greatest sorcerer in the world!
Tom Riddle: Dumbledore's been driven out of this castle by the mere memory of me.
Harry Potter: He'll never be gone. Not as long as those who remain are loyal to him.
(Harry found the entrance to the Chamber of Secrets...)
Gilderoy Lockhart: Excellent, Harry. Good work. Well, then, I'll just be... There's no need for me to stay.
Harry Potter: Yes, there is. You first.
Gilderoy Lockhart: Now, boys, what good will it do?
Ron Weasley: Better you than us.
Gilderoy Lockhart: But... Obviously, yes. Sure you don't want to test it first?
(Ron pushes him...)
