Mysterious Walker at Hogwarts

"What should we do?" Several people from the wizarding world didn't know how to start. Although Hermione was born as a Muggle, her interest in sports was average, so she didn't have much experience.

"It's very simple. First we need a banner, the bigger the better." Dean is very familiar with this.

"How about this?" Ron ran back to the dormitory and pulled out a sheet stained by the pet rat Scabbers.

"Well, let's make do." Dean looked at the stain in the corner of the bed sheet with disgust. If he hadn't considered Banban's true identity and the unforeseen consequences of refusing, Dean would have really not wanted to use this bed sheet.

"Clean up!" After noticing Dean's expression, Hermione cast a cleaning spell, and the sheets became as good as new.

Dean took out the set of Mark Harding's limited edition paints that Fianna had given him, first wrote the words "Potter Must Win" on the bed sheet, and then began to wave the paintbrush under the gaze of everyone.

About an hour later, a huge, lifelike Gryffindor lion appeared on the sheets.

"Dude, I didn't expect you to be quite talented in art." Seamus opened his mouth in surprise.

"Seamus, keep your mouth shut. If you spread the word about me again, you will lose my friendship." Dean warned.

"Okay, let's see the effect?" Simo suggested after a perfunctory sentence.

Ron and Neville each grabbed the two corners of the sheet and stretched it out for everyone to see.

"The effect is good." Seamus touched his chin and commented.

"I think it's not even interesting - what do you think?" Dean looked at Hermione who was eager to give it a try.

"Can I make a suggestion?" Hermione asked cautiously.

Since the troll incident, Hermione has realized her problems, has become much more restrained, and doesn't care so much about breaking school rules. This makes her much more lovable, and she is gradually accepted by others.

"Say it," Ron said.

"I don't mean anything else. I just think this lion is not vivid enough and it is difficult to attract others' attention in a fierce competition." After Hermione finished speaking, she glanced at Dean worriedly.

"I guess you must have thought of a solution to this problem?" Dean looked at Hermione with a smile.

"Maybe I can use a three-dimensional charm on it to make it look more real, and then use a voice charm to make our cheering voice for Harry stay on it, and then use a loud voice charm to come out of its mouth - this way Would the effect be better?" After Hermione finished speaking, she found that everyone else was looking at her in disbelief.

"Hermione, have you mastered all these spells?" Neville looked at Hermione with admiration and said.

"A little bit." Hermione said modestly, a little embarrassed.

"Let's do it." Dean agreed.

Immediately afterwards, Hermione showed everyone her outstanding talent and skills in spell casting - after continuously casting the three-dimensional spell, the voice spell and the loud voice spell, the cheering banner simply became an automatic cheering device.

"Dean, what do you think?" Hermione asked a little proudly.

"It's perfect. Now I just need to use another solidification spell to fix these effects - you do it or I do it." Dean said and pulled out the blackthorn wand - after the troll incident, Dean re- Linked the magic power to the Thunderbird wand.

"Come on. I'm not very proficient in the solidification spell yet." Hermione put away her wand. It seemed that she had indeed matured a lot.

Dean waved his wand with satisfaction and applied a solidifying spell to the cheering banner, fixing a series of magic spells.

"Ron, please keep it and take it out during the game to give Harry a surprise." Dean said to Ron.

"Of course there is no problem, but what about this three-dimensional lion?" Ron was a little worried. This lion was too conspicuous.

"A simple Smoothing Charm can solve it. We just learned it not long ago-" Hermione suddenly realized something at this point and quickly covered her mouth with her hands.

"Hermione is right, you need to learn how to use magic." Dean said, using a smoothing spell to temporarily flatten the three-dimensional lion, then folded the cheering banner and handed it to Ron.

Ron, Seamus and Neville all looked at Dean and Hermione with strange eyes, as if they were wondering when they had become so in tune with each other.

……

The day of the first Quidditch match soon arrived, between Gryffindor and Slytherin.

On the morning of the competition, Harry seemed very nervous and didn't even have an appetite for breakfast.

"You must have a few bites of breakfast." Ron tried to get Harry to eat something.

"I don't want to eat anything."

"Eat some toast," Hermione joined in the persuasion.

"I'm not hungry."

"Harry, you need to maintain strong physical strength." Seamus said, "The seeker is always the person that the opponent should guard against."

——Unfortunately, it still has no effect.

"Dean?" Ron looked at Dean for help.

"That's enough! I told you I'm not hungry!" Before Dean could think of how to speak, Harry stood up from the dining table very irritably and walked towards the Quidditch pitch.

"I'll come as soon as I go." Dean grabbed a few pieces of toast and two sausages on the table and chased after them.

"Hey, Harry, wait for me." Taking advantage of his height and long legs, Dean caught up with Harry in two steps.

"Dean, please, don't bother me." Harry said in a low voice. He didn't want others to notice that he was nervous.

"I just wanted to join you on the way." Dean said easily, "You know I come from a Muggle family and have never watched a Quidditch match before, so I want to go to the stadium early to get familiar with it - you can give it to me at your convenience Can you introduce me?"

"Well, of course. The rules of Quidditch are easy to understand, although not easy to play. There are seven people on each side, three of them are called chasers..." Harry began to explain incessantly.

Dean could see that Harry was definitely a natural Quidditch player. When he talked about Quidditch, he was full of confidence, and the previous nervousness had long since disappeared.

Dean took advantage of Harry to get to the exciting part and calmly handed Harry the bread and sausages in his hands. Harry, who was in high spirits, finished the food without even realizing it - almost the equivalent of two hours of food. Meal size.

Dean was even a little worried whether eating too much would affect his condition.

"Are you feeling better now? Gryffindor's youngest Seeker in a century?" Dean said to the hiccupping Harry with a smile on his face when they arrived at the Quidditch pitch.

"Thank you, Dean, but I think I ate a little too much." Harry thanked him sincerely.

He had already realized Dean's intention.

"It doesn't matter. There's still some time before the start of the game. You can warm up and digest it." Dean suggested.

"I will." Harry nodded.

"Then I'm going to the stands." Dean pointed to the stands with the Gryffindor flag, "If you have time, pay attention over there. We have prepared a gift for you."

"Thank you, I'll keep an eye out."

"See you later, we are waiting for your good news."

"Um... Dean, can you predict the outcome of the game?" Harry hesitated and stopped Dean who was about to leave.
