“Well – let’s drink to a Gryffindor victory against Ravenclaw! Not that I’m supposed to take sides, as a teacher …”

Lupin, Prisoner of Azkaban, Ch. 12

“Do not expect me to cover up for you again, Harry. I cannot make you take Sirius Black seriously. But 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. A poor way to repay them – gambling their sacrifice for a bag of magic tricks.”

Lupin, Prisoner of Azkaban, Ch. 14

“You’re the cleverest witch of your age I’ve ever met, Hermione.”

Lupin, Prisoner of Azkaban, Ch. 17

“I have no hesitation in saying that James would have been highly disappointed if his son had never found any of the secret passageways out of the castle.”

Lupin, Prisoner of Azkaban, Ch. 22

“People have said it, many times. It comes down to whether or not you trust Dumbledore’s judgement. I do; therefore, I trust Severus.”

Lupin, Half-Blood Prince, Ch. 16

“I neither like nor dislike Severus. No, Harry, I am speaking the truth. We shall never be bosom friends, perhaps; after all that happened between James and Sirius and Severus, there is too much bitterness there. But I do not forget that during the year I taught at Hogwarts, Severus made the Wolfsbane Potion for me every month, made it perfectly, so that I did not have to suffer as I usally do at the full moon.”

Lupin, Half-Blood Prince, Ch. 16

“Sometimes you remind me a lot of James. He called it my “furry little problem” in company. Many people were under the impression that I owned a badly behaved rabbit.”

Lupin, Half-Blood Prince, Ch. 16

“My kind don’t usually breed! It will be like me, I am convinced of it – how can I forgive myself, when I knowingly risked passing on my own condition to an innocent child? And if, by some miracle, it is not like me, then it will be better off, a hundred times so, without a father of whom it must always be ashamed!”

Lupin, Deathly Hallows, Ch. 11

(“And what would you say to Harry if you knew he was listening, Romulus?”) “I’d tell him we’re all with him in spirit. And I’d tell him to follow his instincts, which are good and nearly always right.”

Lupin, Deathly Hallows, Ch. 22
