Lupin didn't agree in the end. As a bystander, Felix could clearly see the professor's reluctance.

He had some guesses. The form of the Patronus had a lot to do with the state of the wizard. Although Lupin tried his best to avoid mentioning the word "werewolf", the influence of this identity on him had already penetrated into his bones. His Patronus was likely to be a wolf or a related subspecies.

Felix didn't know what to say, 'Severus is really ..."

...

One night, Ron crawled in from the common room alone.

"Snape is a pervert! He*..." Ron cursed, causing Hermione to shout uncomfortably: "Ron, don't swear!"

He sat down on the soft chair next to Harry, with a strong smell of detergent on his body.

Harry looked at Ron with sympathy. This was not the first time he lost his temper because of Snape. When Professor Lupin was sick and Snape was substituting for him, Ron was punished to clean the chamber pot in the school hospital and was not allowed to use magic because he contradicted Snape in public.

Snape seemed to intentionally prolong this painful process. He divided the punishment into three times. After each punishment, Ron was as angry as a grumpy lion.

"I'm serious. Snape is a very twisted person. If he hadn't only taught one class..." Ron said angrily, "I didn't write a single word of the paper he assigned. Ha! Sure enough, it was cancelled by Professor Lupin!"

Hermione's expression was not very good. Most of the students in the class were watching, but she had already finished her paper on werewolves.

Ron said sarcastically, "Maybe someone stuffed his head into the toilet when he was at school. Look at his hair, Harry." He looked at Harry, "Didn't you stay tonight to ask Professor Lupin? Did he reveal any information about this?"

Harry said gloomily, "No, I asked him about Dementors and my mother."

Ron's expression eased. He exchanged glances with Hermione and asked in a low voice, "You heard it again on the day of the Quidditch match..."

"Yeah," said Harry, "it's the second time. I was particularly vulnerable facing the Dementors. Professor Lupin said it was because I had experienced more pain." He whispered, "He's right. I heard my mother's dying voice over and over again."

"But," Harry cheered up, "Professor Lupin told me a lot about my mother. You know, I've only seen her in the photo Professor Hagrid gave me and in the Mirror of Erised. No one else mentioned her much..."

"Harry..." Hermione looked at him worriedly.

Harry went on regardless, "I thought Mom had a gentle personality. That's how I imagined her to be, but she's not. Professor Lupin said she was very opinionated, even a little bit aggressive. In that era, she maintained her friendship with her neighbor from a rival college, Snape, for five years. Professor Lupin said he admired her very much." "

Of course! Mom and Snape eventually parted ways because of Voldemort!" Harry said excitedly, "Mom had to grow up. When she first entered school, she didn't know about the war started by Voldemort, but how could a person fight against reality? Every few days, a classmate's family or relatives died, and every month a few classmates dropped out. This is war, isn't it?"

"She must have struggled and hesitated for a long time, but in the end she ended this friendship. Professor Lupin said she was depressed for a long time, and my father comforted her and told her a lot about the Order of the Phoenix, and they naturally came together..."

"Marriage, fighting against Death Eaters, escaping from Voldemort's pursuit, and me," Harry's expression darkened, "until they mistakenly trusted Sirius Black."

Ron said uneasily: "Harry, are you okay?"

"I'm fine." Harry said: "Professor Lupin promised to teach me the Patronus Charm after Christmas. But he rejected my request for special training. Professor Happ was too busy, and I didn't dare to mention it."

"When I wrote the duel system paper, I always used Black as my imaginary enemy, but in fact I can't do much, just a few spells. I'm not proficient yet..."

Ron said, "Harry, we can train ourselves."

Harry stopped talking, looked up at Ron, and said slowly, "Train by ourselves?" This made Ron a little uneasy. He said, "I know I'm weaker and not your opponent, but if you need me, I can be your assistant."

He came up with another bad idea, "If it doesn't work, we can practice with Slytherin students. Malfoy's group is good. Crabbe and Goyle look like they can withstand a few more spells."

Harry thought of Crabbe, who was muscular, and Goyle, who looked like a gorilla, and couldn't help grinning. He restrained his smile and said seriously, "Thank you, Ron."

Ron blushed, "No, nothing."

"Then what are we waiting for?" Hermione looked relieved. She took out a piece of parchment and quickly wrote and drew on it.

"If we want to train on our own, we must be fully prepared, choose the right time and place, choose the right spells, and prevent accidents... There are many things to do!" Hermione said vigorously.

"Hermione?" Ron looked at her dumbfounded.

But Hermione has already entered the working state, "My schedule is different from yours, but... I should be able to find time..."

"How do you find time?"

"Don't interrupt me, Ron." Hermione said impatiently, "It is best to refer to the content of the duel class for the choice of spells. Harry, I need your paper."

Harry handed her the written paper stupidly.

"I will help you hand it over to Professor Hepp, but I need to take a look first and summarize your duel ideas. And Ron, you can't relax either, you can't be too far behind." Ron

had a bitter face, "You don't want me to write a paper too, Professor Binns just left a two-foot homework, you know."

"Well, if you don't plan to, I mean, I can lend you the homework for reference." Hermione tried her best not to mention the word "copy".

Ron whispered to Harry, "She really surprised me."

Harry shrugged and said in a relaxed tone, "That's Hermione. Hasn't she surprised us enough?"

Hermione was still thinking hard, "Maybe we can get a few more people. Of course, the three of us will spend the most time together, but others may also be interested, and their levels are generally good. The dueling class really helps a lot!

Dean is very proficient in the Stunning Spell, and Seamus's Explosive Spell is also exaggerated. He must be very talented in this area... And Neville, Ginny's little evil spells are quite good. I didn't expect her to learn so quickly when I taught her. We can even ask Percy for help. He owes the twins a favor, and the twins" she laughed, "they owe me a lot of favors."

"Wait," Ron shouted, "what's going on with Percy, Fred and George?"

"Remember the couple's mirror? They gave Penelope a 50% discount. She was going to give it to Percy as a Christmas present, but Percy found the twins privately..."

"Then how are you related to Fred and George?" Ron still couldn't understand. His two brothers were not easy to talk to.

"Oh," Hermione said with a bright smile, "I'm the assistant in the Ancient Runes class. They often ask me for reference books, the kind with specific page numbers. They say it's to save time. Theoretical ancient runes are not worth their time."
