From CoS the movie (2002).
Harry: Albus Dumbledore is the greatest sorcerer in the world!
Tom Marvolo Riddle: Dumbledore has been driven out of this castle by the mere memory of me.
Harry: He'll never be gone! Not as long as those who remain are loyal to him!
"Are all your family wizards?" asked Harry, who found Ron just as interesting as Ron found him.
"Er - yes, I think so," said Ron. "I think Mum's got a second cousin who's an accountant, but we never talk about him."
"Scars can come in useful. I have one myself above my left knee which is a perfect map of the London Underground."
-Dumbledore
"So, light a fire!" Harry choked.
"Yes - of course - but there's no wood." Hermione cried, wringing her hands.
"HAVE YOU GONE MAD?" Ron bellowed. "ARE YOU A WITCH OR NOT?"
