Prisoner of Azkaban

'No need to tell us he’s [Sirius’s] no good. Look at the state of him, the filthy layabout! Look at his hair!’ — Uncle Vernon

'Scary-lookin' fing, inee?' — Stan on Sirius

'They say Sirius Black's mad, and maybe he is, but he was clever enough to escape from Azkaban, and that's supposed to be impossible.' — Mr Weasley

"The stranger was wearing an extremely shabby set of wizard’s robes which had been darned in several places. He looked ill and exhausted. Though he seemed quite young, his light-brown hair was flecked with grey." — About Remus

"And then, from far away, [Harry] heard screaming, terrible, terrified, pleading screams. He wanted to help whoever it was, he tried to move his arms, but couldn’t …"

'Eat. It'll help.' — Remus, handing Harry some chocolate.

The very first time I saw you Harry, I recognised you immediately. Not by your scar, by your eyes. They’re your mother, Lily’s. Yes, I knew her. Your mother was there for me at a time when no one else was. Not only was she a singularly gifted witch, she was also an uncommonly kind woman. She had a way of seeing the beauty in others, even, and perhaps most especially, when that person couldn’t see it in themselves. Your father, James, however, had a certain, shall we say, talent for trouble. A talent, rumour has it, he passed onto you. You’re more like them then you know, Harry. In time you’ll come to see just how much.’ — Remus (film)

'That suggests that what you fear most of all is — fear.' — Remus to Harry

'He's the best Defence Against the Dark Arts teacher we've ever had!' — Dean Thomas about Remus

“‘Not Harry, not Harry, please not Harry!’
  ‘Stand aside, you silly girl … stand aside, now …’
  ‘Not Harry, please no, take me, kill me instead -‘
  Numbing, swirling white mist was filling Harry’s brain … What was he doing? Why was he flying? He needed to help her … she was going to die … she was going to be murdered …
  He was falling, falling through the icy mist.
  ‘Not Harry! Please … have mercy … have mercy …’”
— Harry hearing his mother’s last moments through Dementors

'I solemnly swear that I am up to no good.'

"Messrs Moony, Wormtail, Padfoot and Prongs
Purveyors of Aids of Magical Mischief-Makers are proud to present
THE MARAUDER’S MAP”

George: ‘Moony, Wormtail, Padfoot and Prongs. We owe them so much.’ Fred: ‘Noble men, working tirelessly to help a new generation of lawbreakers.’

'Do you know, I still have trouble believing it. Of all the people to go to the dark side, Sirius Black was the last I'd have thought …' — Madam Rosmerta

'Never saw one without the other, did you? The number of times I had them in here — ooh, they used to make me laugh. Quite the double act, Sirius Black and James Potter!' — Rosmerta

'Black and Potter. Ringleaders of their little gang. Both very bright, of course — exceptionally bright, in fact — but I don't think we've ever had such a pair of trouble makers —' — McGonagall

Professor Flitwick: ‘You’d have thought Black and Potter were brothers. Inseparable!’ Fudge: ‘Of course they were. Potter trusted Black beyond all his other friends. Nothing changed when they left school. Black was best man when James married Lily. Then they named him Godfather to Harry.’

'James Potter told Dumbledore that Black would die rather than tell where they were, that Black was planning to go into hiding himself …' — McGonagall

'… An' Sirius Black turns up, on that flyin' motorbike he used ter ride. […] Thought he'd jus' heard the news o' You-Know-Who's attack an' come ter see what he could do. White an' shakin' he was.' — Hagrid

'An' then he says, “Give Harry ter me, Hagrid, I'm his godfather, I'll look after him —' — Hagrid

'Pettigrew … that fat little boy who was always tagging around after them at Hogwarts?' — Rosmerta

'Hero-worshipped Black and Potter. Never quite in their league, talent-wise.' — McGonagall

Lily, take Harry and go! It’s him! Go! Run! I’ll hold him off

Harry: ‘I heard my dad. That’s the first time I’ve ever heard him - he tried to take on Voldemort himself, to give my mum time to run for it …’ Remus: ‘You heard James?’ Harry: ‘Yeah … Why — you didn’t know my dad, did you?’ Remus: ‘I — I did, as a matter of fact. We were friends at Hogwarts …’

'That was quite some Patronus,' said a voice in Harry's ear. // Harry turned around to see Professor Lupin, who looked both shaken and pleased. // ‘The Dementors didn’t affect me at all!’ Harry said excitedly.

Snape: ‘Your father didn’t set much store by rules either. Rules were for lesser mortals, not Quidditch Cup-winners. His head was so swollen —’ Harry: ‘SHUT UP!’

Mr Moony presents his compliments to Professor Snape and begs him to keep his abnormally large nose out of other people’s business.' // 'Mr Prongs agrees with Mr Moony, and would like to add that Professor Snape is an ugly git.' // 'Mr Padfoot would like to register his astonishment that an idiot like that ever became a professor.’ // 'Mr Wormtail bids Professor Snape good day, and advises him to wash his hair, the slimeball.'

'These mapmakers would have wanted to lure you out of school. They'd think it extremely entertaining.' — Remus

'… I would have thought that what you have heard when the Dementors draw near you would have had more of an effect on you, your parents gave their lives to keep you alive, Harry.' — Remus

'I thought you'd come and help your friend. Your father would have done the same for me.' — Sirius

Remus: ‘Looking a bit ragged, aren’t we, Sirius? Finally the skin reflects the madness within.’ Sirius: ‘You’d know all about the madness within, wouldn’t you, Remus?’ (Film)

‘I did my waiting! Twelve years of it! In Azkaban! Trust me, you wouldn’t have lasted a week!’ — Sirius (film)

Snape: ‘I told Dumbledore you were helping your old friend into the castle. And here’s the proof.’ Sirius: ‘Brilliant! And – as usual – dead wrong.’ (film)

Sirius: ‘The Map never lies. Pettigrew’s alive. And he’s right there.’ *Points at Ron.* Ron: ‘M-me? It’s lunatic …’ Sirius: ‘Not you, you idiot. Your rat.’ (film)

‘I was a very small boy when I received the bite. My parents tried everything, but in those days there was no cure.’ — Remus

‘The truth is that [the Whomping Willow] was planted because I had come to Hogwarts.’ — Remus

‘For the first time ever, I had friends, three great friends. Sirius Black … Peter Pettigrew … and, of course, your father, Harry – James Potter. […] I was terrified that they would desert me the moment they found out what I was. But, of course, they, like you, Hermione, worked out the truth … And they didn’t desert me at all. Instead they did something for me that would make my transformations not only bearable, but the best times of my life. They became Animagi.’ — Remus

‘Your father and Sirius here were the cleverest students in the school […] Peter needed all the help he could get from James and Sirius. Finally, in our fifth year, they managed it.’ — Remus

“‘Harry … I as good as killed them,’ [Sirius] croaked. ‘I persuaded Lily and James to change to Peter at the last moment, persuaded them to use him as Secret-Keeper instead of me … I’m to blame, I know it […] I was scared. I set out for your parents’ house straight away. And when I saw their house, destroyed, and their bodies – I realised what Peter must have done. What I’d done.’ // His voice broke. He turned away.”

“He was a very short man, hardly taller than Harry and Hermione. His thin, colourless hair was unkempt and there was a large bald patch on top. He had the shrunken appearance of a plump man who had lost a lot of weight in a short time. His skin looked grubby, almost like Scabbers’s fur, and some of the rat lingered around his pointed nose, his very small, watery eyes.” — About Peter Pettigrew

‘I, a spy for Voldemort? When did  I ever sneak around people who were stronger and more powerful than myself? But you, Peter – I’ll never understand why I didn’t see you were the spy from the start. You always liked big friends who’d look after you, didn’t you? It used to be us … me and Remus … and James …’ — Sirius

‘Believe me. I never betrayed James and Lily. I would have died before I betrayed them.’ — Sirius

‘James wouldn’t have wanted me killed … James would have understood, Harry … he would have shown me mercy …’ — Peter

‘THEN YOU SHOULD HAVE DIED! DIED RATHER THAN BETRAY YOUR FRIENDS, AS WE WOULD HAVE DONE FOR YOU!’ — Sirius

‘This cringing but of filth would have seen you die, too, without turning a hair. You heard him. His own stinking skin meant more to him than your whole family.’ — Sirius on Peter

'Beautiful, isn't it? I'll never forget the first time I walked through those doors. It'll be nice to do it again. Freely.’ — Sirius looking at Hogwarts

“There was a terrible snarling noise. Lupin’s head was lengthening. So was his body. His shoulders were hunching. Hair was sprouting visibly on his face and hands, which were curling into clawed paws.” — Remus’s transformation

‘You are – truly your father’s son, Harry …’ — Sirius

‘It’s cruel that I got to spend so much time with James and Lily, and you so little. But know this; the ones that love us never really leave us. And you can always find them in here.’ — Sirius (film)

Harry: ‘You told me Moony, Wormtail, Padfoot, and Prongs would’ve wanted to lure me out of the school … you said they’d have thought it was funny.’ Remus:  ‘And so we would have. I have no hesitation in saying that James would have been highly disappointed if his son had never found any of the secret passages out of the castle.’

‘You think the dead we loved ever truly leave us? You think that we don’t recall them more clearly than ever in times of great trouble? Your father is alive in you, Harry, and shows himself most plainly when you have need of him. How else could you produce that particular Patronus? Prongs rode again last night.’ — Dumbledore
