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.
