Mysterious Walker at Hogwarts

At this time, the commotion coming from the second floor became louder and louder. It was obvious that Harry and others had not yet dealt with the troll.

Dean scanned the figure of Professor McGonagall rushing towards the second floor, thinking that it would be solved soon, so when he walked to a staircase leading to the eighth floor, he took the initiative to say to Snape: "Professor, I remembered You're on your way, go to the top of this staircase, then turn right and you'll see the portrait of the Fat Lady."

"Are you sure? I remember turning left." Snape asked worriedly.

"I remember, go to the top and turn left." Dean nodded, "If your legs are inconvenient, there is no need to send me up."

"Then be careful." Snape thought for a moment. The disturbance was obviously coming from downstairs. Even if Dean couldn't find a way to wander around, he probably wouldn't encounter a troll, so he finally relented.

"Don't worry." Dean said and rushed up the stairs without looking back.

The reason why he was so anxious was because he felt Ron's wand casting a magic spell through the magic link. In order to ensure nothing went wrong, Dean must provide timely assistance through the magic link.

Obviously this couldn't be done in front of Snape.

Dean ran up a few steps, and after confirming that Snape had walked towards the second floor, he waved the blackthorn wand and chanted the levitation spell - this is what Ron did in the original book, and Dean only You can choose to take a gamble.

On the second floor of the castle, in the messy women's bathroom, Harry was wrapping his arms around the troll's neck from behind.

He jumped up with his wand in his hand and thrust it straight into one of the troll's nostrils.

The troll roared in pain, twisted around, and waved the wooden stick in his hand. Harry hugged it tightly; the troll would throw him off at any time, then grab him and kill him with the wooden stick. A blow.

Completely petrified, Hermione collapsed on the floor.

Ron realizes that only he can possibly save Harry.

When he pulled out his wand but was at a loss, he suddenly thought of what Dean had said casually before: "The troll's weak point is at the back of its head."

Ron suddenly had an idea.

He pointed at the thick wooden stick in the troll's hand and shouted: "Wingardim Leviosa!"

Because the troll kept waving the stick, Ron spent some time aiming, but by chance, he bought some time for Dean, who was not at the scene.

Finally the levitation spell took effect.

The wooden stick suddenly flew out of the troll's hand, spinning high into the air, and then fell heavily, hitting its owner on the back of the head with an earth-shattering explosion.

The troll swayed on the spot and collapsed face down on the floor with a boom that shook the entire room.

……

"It should be fine, right?" Through the magic link, Dean clearly sensed that the levitation spell had taken effect, but at such a distance, he was not sure to what extent the magic power had weakened, and whether it had the same effect as in the original work - until There was sudden silence downstairs, followed by Professor McGonagall's sharp and angry shout.

"What the hell are you playing? You're lucky not to be killed by it! Why don't you just stay in the dormitory..."

Dean swore that he had never seen Professor McGonagall so angry, but this meant that Harry and others were safe.

Dean put away his wand proudly, hummed an unknown tune and walked towards the Fat Lady. This was exactly the effect he wanted!

After the Halloween troll incident, Hermione became good friends with Harry and Ron. Dean was very pleased to see that the Iron Triangle was beginning to take shape - after he had secretly intervened in many things, history still moved forward according to the original track, at least Proof is still under control.

As for who is in control, Dean doesn't care.

The only impact of this incident on Dean was that his "prophecy" talent became more famous - after all, that morning he had just "predicted" that Hermione would soon make friends, and there were more than one. This strange incident allowed Hermione to achieve this "making friends" achievement that was almost impossible in the eyes of others.

With Seamus' big mouth spreading everywhere, Dean once again enjoyed the feeling of being the center of attention at the beginning of school - this bad situation did not ease until November, when the Quidditch season started.

As a time traveler, it was difficult for Dean to understand wizards' enthusiasm for Quidditch.

But after being forgotten again, Dean finally had the opportunity to go to Snape and get the reward he deserved long ago.

After a Potions lesson that was as bad as the weather for a new Gryffindor, Dean excused himself and stayed.

"Professor, are your legs feeling better? I noticed that your movements are still a bit inconvenient." Before getting down to business, Dean expressed concern.

"If you want, I can get it done right away, but I was told that you have to do enough drama." Snape waved his hand impatiently, "Let's get down to business, Mr. Thomas."

"Professor, you promised to teach me the Shadowless Curse and its counter-curse last time." Dean felt a little embarrassed after being exposed.

"Mr. Thomas, your timing is not good." After all the students left, Snape waved his wand and closed the classroom door before saying to Dean with a straight face.

"I'm sorry, Professor. I can't wait any longer." Dean felt a bit arrogant. He felt that he had almost grasped Snape's psychology.

Snape's lips curled up and he spoke slowly and in a long voice: "Mr. Thomas, I noticed that you have used my dispensing device and 'wasted' a lot of precious materials."

"Professor, that happened just after the semester started. I thought you had forgotten about it." Dean scratched his head in embarrassment, a little confused as to why Snape only mentioned that matter now.

"I'm not old enough yet," Snape said sarcastically.

"Then..." Dean spread his hands, "Do you need me to compensate you?"

"Compensation——" A hint of displeasure flashed clearly on Snape's face, "Maybe I shouldn't let you come into contact with Mundungus..."

"What?" Dean looked at Snape confused, not understanding what he was implying.

"Perhaps it was his influence that made you become so philistine." Snape looked at Dean disapprovingly.

After Dean cried bitter tears for the innocent Mundungus, he secretly warned: It seems that his utilitarianism is too strong and should never appear in children of his age.

"Okay, Professor. I know I was wrong." Dean replied honestly.

"Very good, so I decided to set up a small test for the reward I promised you." Snape was very satisfied with Dean's attitude of admitting his mistake.

"What kind of test?" Dean was slightly nervous.

"It's very simple. When you memorize all the recipes in this book, I will fulfill my promise." Snape pushed a tattered book that was not selling well in front of Dean.

It was "Advanced Potion Making" written by Libasio Pollachi.
