How we cite our quotes: All quotations are from Harry Potter and the Order of the Phoenix.
Quote #1
SIRIUS BLACK: We think Voldemort wants to build up his army again. Fourteen years ago he had huge numbers at his command, not just witches and wizards but all manner of dark creatures. He has been recruiting heavily and we have been attempting to do the same. But gathering followers isn't all he's interested in. We believe Voldemort may be after something...
MAD-EYE MOODY: Sirius!
SIRIUS BLACK: Something he didn't have last time.
You could say that Voldemort's a little bit obsessed with the past. He wants to get his hands on this prophecy so he can figure out his connection to Harry Potter… and why he failed to murder him all those years ago. Seriously: step into the present, Voldy.
Quote #2
SIRIUS BLACK: I wanted you to have this. Original Order of the Phoenix. Marlene McKinnon. She was killed two weeks after this was taken. Voldemort wiped out her entire family. Frank and Alice Longbottom. Neville's parents. They suffered a fate worse than death, you ask me. It's been fourteen years and still a day doesn't go by I don't miss your dad.
HARRY POTTER: Do you really think there's going to be a war, Sirius?
SIRIUS BLACK: It feels like it did before. You keep it. Anyway, I suppose you're the young ones now.
Sirius is pretty wistful about the old Order of the Phoenix, but those were the good old days when his best friends were alive and he hadn't spent twelve years in prison for a crime he didn't commit. Of course, there's nothing wrong with looking back if it provides you good intel for the present.
Quote #3
KREACHER: Nasty brat, standing there as bold as brass. Harry Potter, the boy who stopped the Dark Lord. Friend of Mudbloods and blood-traitors alike. If my poor mistress only knew...
SIRIUS BLACK: Kreacher! That's enough of your bile. Away with you!
KREACHER: Of course, master. Kreacher lives to serve the noble house of Black.
SIRIUS BLACK: Sorry about that. He never was very pleasant, even when I was a boy. Not to me, anyway.
One thing Sirius is not wistful about—his childhood. He can't stand the ancient house elf that looks after his family house. The feeling seems to be mutual. Kreacher is just as racist and awful as the Black family who used to live in this house. Guess everyone who lives at 12 Grimmauld Place is stuck in the past.
