Placing Katrina's riddle bet during the Quidditch game was undoubtedly because she didn't want other people to watch. Perhaps Isobel had her own considerations and obviously didn't want too many people to know the secret of entering and leaving Ravenclaw.
Although, the chances of students from other houses being able to successfully answer the riddle and gain access to the Ravenclaw common room are low.
"Wait!"
Before Isobel turned and left, Albert suddenly called her.
"Is there something?" Isobel stopped and turned to look at Albert.
"Do you know that Professor Snape has a certain ability? When I look into his eyes, I feel like he sees through me." Albert took a few quick steps and walked side by side with Isobel in the corridor. "Do you know what this is?"
"Why do you think so?" Isobel was silent for a moment and asked.
"I think this should be a kind of magic." Albert said as he walked: "In the Muggle world, there is a term called mind reading."
Isobel stopped, stared at Albert and asked, "Do you want to learn this kind of magic?"
"No, I want to find a way to counter him." Albert looked helpless. "No one wants others to understand what they are thinking, especially Professor Snape. To be honest, I hate the feeling of being seen through."
"You mean Legilimency?"
"So, it is indeed a kind of magic." Albert showed an expression that said it was as expected.
"Legitimate memory can be used to cheat on exams." Isobel also stopped and looked Albert up and down, and suddenly said, "Of course, you probably don't need to cheat."
"Is there any way to counter it?" Albert immediately asked, "I mean magic that can protect yourself from being understood by others."
"Brain Occlumency, there should be such books in the restricted area." Isobel stared into Albert's eyes and said coldly: "Actually, you know, right!"
"What's the matter?" Albert's heart skipped a beat and he immediately looked away, pretending to be puzzled and asked.
"About Occlumency." Isobel's expression remained the same. "Or Legilimency."
"Well, I found similar statements in the library, but I didn't find any relevant books." Albert knew that he couldn't hide it from the other party, so he didn't continue to play dumb, otherwise he would really become a fool.
Isobel looked at Albert deeply and looked away.
"I hope to find relevant books. Of course, it would be even better if you know how to use this magic and are willing to teach me." Albert said with a smile.
"I do know Occlumency," said Isobel.
It really does!
Albert was just talking casually just now, but he didn't expect Isobel to say that she knew the brain-blocking technique!
Albert was silent for a moment, then suddenly thought of a possibility, and asked tentatively, "Did Mr. McDougal teach you?"
"Why do you ask that?" Isobel asked calmly, because Albert guessed right.
"So, I guessed right." Albert said to himself, "This Easter, Professor Broad took me to attend Mr. McDougal's party..."
Isobel suddenly made a hushing gesture to him. Someone was walking towards them from the other side of the corridor. It was Professor Smith.
Although Albert was a little confused, he didn't say anything more about it. When he turned around, he found that Professor Rowena Smith had appeared a few steps away from them.
"Good afternoon." Professor Smith greeted the two with a smile, and then his eyes fell on Albert, "Have you written back to them?"
"Yes, he wrote back to me a few days ago." Albert nodded.
"That's good." Professor Smith suddenly asked, "By the way, what are you talking about?"
"We are discussing ancient magic runes." Albert explained casually, "Professor Barbling is preparing to publish a book related to ancient magic runes, and she hopes that I can help her revise the manuscript for this part. Isobel is also very good at ancient magic runes, and I am asking her if she is willing to help."
"Revise the manuscript?" Smith looked at Albert in surprise. He remembered that Mr. McDougal had asked Albert to do the same thing before, so he felt relieved.
"My attainments in ancient magic runes are far inferior to Albert's." Isobel declined politely.
"Well, that's a good thing." Professor Smith said with a smile, "When you're done, remember to tell me so I can buy a copy and read it."
"I'll write it down," Albert said seriously. He actually took out a notebook from his pocket and simply wrote down this sentence.
At this moment, both Isobel and Professor Smith were stunned.
None of them expected that Albert actually wrote this down.
After Professor Smith walked away, the two continued the previous topic.
"By the way," Albert asked. "Can you teach me Occlumency?"
"Why should I teach you?" Isobel asked back.
"I have Galleons." Albert said without hesitation.
"I'm just getting started." Isobel was not lying. She learned the art of brain block this summer vacation. As Albert said, his uncle Mog McDougal taught her.
However, does what you just said count as agreement
"It doesn't matter. I just need you to show me the way." Albert said without hesitation, "I will figure out the rest on my own."
Albert crossed his two index fingers and said, "How about this price?"
"You really are rich?" Isobel said meaningfully.
"Learning Apparition also requires Galleons." Albert didn't care. "Of course, since you are not a regular student, I think the price is appropriate."
"Okay, as long as you don't regret it." Isobel agreed.
"When does it start?" Albert asked.
"On Sundays, once a week, in the Transfiguration Club classroom." Isobel thought for a moment and reminded, "Don't hold your expectations too high. I'm not good at Legilimency. Also, I won't return Galleons."
"No problem." Albert said with a smile, "If you know of any books on Occlumency, please tell me."
"This... A Guide to Advanced Occlumency." Isobel hesitated for a moment, then said, "This is the book my uncle showed me. If you want to find it, you should be able to find it in the restricted section of the school."
"See you this weekend!" Albert nodded and prepared to leave.
"Aren't you worried that I'll lie to you?" Isobel asked curiously.
"Will you?" Albert asked back, "Besides, I have Galleons."
Isobel's face twitched. This kind of talk always made her feel like a rich man. Of course, she believed Albert's words. After all, how could a guy who took out ten Galleons to bet with Katrina be short of Galleons
As for using this matter to make fun of yourself
Isobel thought that unlikely.
Although the trust between the two parties was not high, their social circles now and in the future were bound to overlap to a large extent. Both Albert and Isobel had actually discovered this. Moreover, both parties were geniuses with their own pride, and would never and would not bother to do something tasteless.
Of course, in Isobel's view, Albert was just a rich sucker, and she didn't think he could easily master the brain-blocking technique.
However, Isobel obviously didn't know that there is such a thing as cheating in this world.
