How we cite our quotes: All quotations are from Harry Potter and the Order of the Phoenix.
Quote #4
SIRIUS BLACK: This is the Black family tree. My deranged cousin. I hated the lot of them. My parents with their pure-blood mania. My mother did that after I ran away. Charming woman. I was sixteen.
HARRY POTTER: Where did you go?
SIRIUS BLACK: Round your dad's. I was always welcome at the Potters'. I see him so much in you, Harry. You are so very much alike.
Sirius has awful memories of his family, but remembers only good things about Harry's dad. We have to wonder if he's giving Harry the honest story here. Is he remembering things like they really were or just thinking of his best friend with rose-colored glasses because he's gone?
Quote #5
HARRY POTTER: This connection between me and Voldemort... what if the reason for it is that I am becoming more like him? I just feel so angry, all the time. What if after everything that I've been through, something's gone wrong inside me? What if I'm becoming bad?
SIRIUS BLACK: I want you to listen to me very carefully, Harry. You're not a bad person. You're a very good person, who bad things have happened to. Besides, the world isn't split into good people and Death Eaters. We've all got both light and dark inside us. What matters is the part we choose to act on. That's who we really are.
Harry wonders if what's happened to him in his past is going to change him for the worst, but Sirius doesn't think so. Sure, bad things have happened to him, but Harry has a choice. He can be a good person or a bad person if he wants to be. Basically, our past doesn't dictate who we become.
Quote #6
NEVILLE LONGBOTTOM: Fourteen years ago, a Death Eater named Bellatrix Lestrange used the Cruciatus Curse on my parents. She tortured them for information, but they never gave in. I'm quite proud to be their son. But I'm not sure I'm ready for everyone to know just yet.
HARRY POTTER: We're going to make them proud, Neville. That's a promise.
Another tragic backstory. Like Harry, Neville doesn't have any parents—except his aren't dead. Just tortured into insanity. Which is worse? That past is back to haunt Neville now that Bellatrix has broken out of Azkaban and is on the move.
