Mysterious Walker at Hogwarts

Tina smiled reservedly and said nothing, but Rolf started to yell: "Dean, you are so slow! I hinted to you last time that grandma is very experienced in making magic artifacts! You forgot That device that monitors Lockhart?"

Dean immediately thought of the strange pocket watch in Rolf's hand.

"Sorry I didn't notice." Dean scratched the back of his head, a little embarrassed.

"It doesn't matter, if the exhortation is of no use to you...what magic artifact do you want? Maybe I can help you make one." Tina smiled.

Rolf looked at his grandma in surprise, seriously suspecting that Dean had used the Imperius Curse on her. He had never seen his grandma take the initiative to make any magical artifacts for others.

"No -" Dean was about to refuse, but suddenly thought of something very important, and immediately changed his mind: "-If it's not too much trouble, I really want to ask you to help make something."

Rolf looked at Dean in disbelief, having a new understanding of how thick-skinned he was. He was so embarrassed to ask his grandma!

"What do you want to make?" Tina asked generously.

"I want you to help make something similar to a monitor to monitor the danger level of an Obscurus. If the Obscurus is about to explode, you can remind me in time." Dean was actually very worried about Knightley, for fear of the Obscurus. It will explode suddenly without him knowing it.

"Monitor? Obscurus?" Tina looked at Dean and asked hesitantly: "Could you be the Obscurus in the prophecy?"

Dean felt nervous. Shouldn't such an important prophecy be kept secret?Why does Tina actually know that?

"No, you're not. I'm not of the right age. So that Obscurial One is your family member?" Tina's words showed that she actually knew a lot.

Noticing the confused expression on Dean's face, Tina immediately reacted and said with a smile: "I guess you must have seen the music box that suppresses the Obscurus? In fact, that is also one of my works."

"So that's it!" Dean suddenly realized. Although Newt said that the music box was the result of his and Dumbledore's research, the two of them obviously did not have such good craftsmanship. They should have provided theoretical and magical support and actually made it. The person is actually Tina, which makes sense.

Now Dean no longer has any psychological burden: "The Obscurus may be my sister. I am very worried that the Obscurus will break out without my knowledge, so can you please make such an alarm device?"

"Of course it's no problem. Theoretically it's not difficult, but it will take some time. I will make it as soon as possible." Tina agreed happily.

"I'm so grateful!" Dean struck while the iron was hot, "Grandma Tina, I actually have something else to do when I come here this time. Can you agree to let Rolf accompany me to find someone?"

"Who are you looking for? Is there any danger?" Tina immediately asked sensitively.

"Go to London to find Remus Lupin." Dean glanced at Rolf who was worried. "The principal wanted me to ask Mr. Lupin face to face about something. He also suggested that Rolf accompany me."

"Remus is a cautious person. Dumbledore asked Rolf to accompany you, probably because he was afraid that you would be too young to win Remus' trust." Tina pondered.

"Do you know Lupin?" Dean was a little surprised. He deliberately didn't mention that Lupine was a werewolf, trying to get away with it. Unexpectedly, Tina mentioned Lupin in a very familiar tone.

"Of course I know." Tina's tone was slightly unhappy, "I also know that he is a werewolf!"

"Grandma Tina, the full moon night has just passed, so Mr. Lupine should be safe in the next month." Dean said quickly.

"Huh, don't I know?" Tina snorted coldly, "If it weren't for this reason, I would have gone to Dumbledore to settle the score - he actually dared to ask Rolf to meet a werewolf!"

"Grandma Tina, calm down. I told you that the principal has thought things through very carefully." Dean said quickly, "Can you let Rolf accompany me?"

"...Okay." Tina conveniently put the admonisher Rolf had been coveting for a long time into his hand, "Be careful, if the admonisher sounds an alarm, you must run away immediately!"

"Is this... just for me?" Rolf held the admonisher in his hands, feeling unreal.

"If you don't want it, just give it back to me!" Tina's face darkened.

"I want it, of course I want it!" Rolf said, immediately hanging the admonisher on his waist and deliberately showing it off.

"Tsk~ look at your potential." Dean seriously despised Rolf for such a mean person.

"Boys, if you are going to find Lupin, act quickly. It is better to see a werewolf during the day than at night!" Tina reminded.

"So you agree that Dean and I will act together?" Rolf confirmed.

"Why did I give you an exhortation?" Tina rolled her eyes at Rolf. This kid was just trying to get an advantage and act like a good boy.

"Grandma, I love you so much!" Rolf said in a very disgusting way.

"Stop doing this, you know what I ask of you, safety, safety is the first priority." After Tina finished speaking, she took out a bottle of brown magic potion and handed it to Dean: "Please give it to me." Give this potion to Lupine, I think it will help you win his trust."

"Grandma, why don't you let me hand it over?" Rolf asked a little annoyed.

"I think Dean is more reliable, okay?" Tina said with a straight face.

"It's so sad that you're going to lose me like this!" Rolf protested.

"Grandma Tina, if I'm not wrong, is this a bottle of wolfsbane potion?" Dean asked.

Tina unexpectedly looked at Dean and said, "The young man is pretty good. He actually recognizes the wolfsbane potion. This is not the level that a first-year wizard should have."

"This is all thanks to Professor Snape's extra 'care' for him~" Rolf put his arm around Dean's shoulders and smiled, "Dean was detained by Snape for a long time, so he mastered these things that he shouldn't have mastered. knowledge."

Dean was helpless and unintentionally let Snape take the blame again. Even if he was willing to defend Snape, no one would believe it.

"It seems I have to write a letter to Snape. It will be helpful to ask him to confine you a few more times." Tina said seriously.

"Wow~ No, grandma, I was just joking!" Rolf panicked.

"I'm not kidding you." Tina said seriously, "You really need to make some adjustments, otherwise what will happen if your OWL fails?"

"Grandma, you have to have some confidence in your grandson's excellence!" Rolf patted his chest and said, "I'm not bragging. Among the students in my class, I am definitely the best one."

"It's a pity that it's not as good as a first-year freshman." Tina said sarcastically.

"Grandma!" Rolf was so shocked that he became autistic. He seriously doubted who was Tina's grandson.
