Lu Ping, who had just accepted the position of professor of Defence Against the Dark Arts, had a similar idea in his heart: Are all the students so strong now? What do you need me to teach when they are so powerful? Is it right or wrong for me to accept this job?

But when he looked down at Harry and Ron, he remembered how they had faced the Dementors...... That's the reaction of a normal child who has just been promoted to the third grade, and the child in front of him who suddenly ran out to protect him with a call for God may be more special...... Truth be told, Lupin wasn't sure if the kid was casting the same spell he was familiar with, had someone modified the Patronus charm?

"Are you alright?"

Leah and Rin Tosaka are not ordinary children, Rin Tosaka has experienced many things even when she was very young, so she can face crises very calmly.

At least compared to Ron and Harry, who were panicked and scared in a cold sweat, these two girls were as if nothing had happened just now.

As for Hermione, she was still struggling with the power gap between herself and Ethan, and had completely forgotten the horror brought by the Dementors.

Sure that the Dementors hadn't had time to hurt anyone here, Ethan finally said hello to Harry and Ron.

Now the relationship between Harry and Ron and Ethan is also considered to be good, and if it weren't for the Slytherin identity, the two would have regarded Ethan as friends.

"Wait, this classmate. ”

Seeing that Ethan was about to leave, Lupin immediately asked about his identity.

"May I ask ...... your name?"

"Ethan. ”

Ethan knew what Lupin wanted to ask, probably wanting to ask Dumbledore about his details, after all, he was definitely not an ordinary student who could release such a powerful Patronus Charm at his age.

First of all, he is definitely a genius among wizards in terms of talent, and secondly, Lupin noticed that Ethan was wearing a Slytherin uniform, so there is a high probability that Ethan is the heir of a wizarding family.

However, Ethan did not report his surname, and he had no way to directly know which family the other party was descended from.

As for whether this would seem rude, Lupin didn't care at all, he had already seen how arrogant and uncaring the descendants of many wizarding families were, and how they didn't take anyone seriously...... In comparison, the young man in front of him at least has enough capital to be proud of, and his strength is still good.

The only episode on the way was the trouble caused by the Dementors, which didn't happen in any of the carriages except Harry, which was on the radar of the Dementors.

I don't know if Harry Potter is too unlucky, or if it's a test he will have to go through as a protagonist.

Nothing happened during the subsequent homecoming, and the Freshman Sorting Ceremony and the welcome and back-to-school dinner went smoothly.

However, when the dinner was over and the students began to go back to their dorms to rest, Ethan was left alone by Dumbledore.

"Go to me. ”

In addition to Ethan, Dumbledore also called Snape and the newly hired Lupin, and Ethan knew as soon as he saw the two men that Dumbledore wanted to ask about the Dementors.

As he expected, after arriving at Dumbledore's office, Dumbledore signaled Ethan to take care of himself and carefully inquired about all the details of what happened to Lupin.

Lupin was in the carriage at the time, so he knew more than Ethan, including the Dementors suddenly breaking into the carriage and intending to attack the students.

"What do you think?"

When Lupin finished speaking, he was surprised to find that Dumbledore was politely asking the young student for his opinion, as if he was not facing a junior Hogwarts student, but a great wizard of his rank.

Glancing at Snape next to him, he didn't seem surprised by this situation, and stood aside very calmly - what was even more unacceptable to Lupin was that Snape was actually making tea for Ethan.

Isn't Snape the head of Slytherin? Why did he make tea for his own students?

"The Dementor attack on the students was indeed an accident. ”

Ethan took the hot tea from Snape, which used some magical plants that had been specially treated, and had a good calming effect on wizards.

Although for Ethan, this effect is equal to nothing, it is hot water with a special taste, but he will not refuse the kindness of others.

"Why Potter?"

Dumbledore feared that this was another ploy by someone to kill Harry Potter by the hands of the Dementors. As for the Dementors being sent by the Ministry of Magic, he knew exactly what was going on in that department.

"Harry has more pain in his heart than other carefree children, maybe it's easier for him to attract the attention of the Dementors?"

Although the Dementors were ostensibly attacking Lea here, Lea only happened to be in front of Harry Potter, and Dumbledore had already determined this from Lupin's description: it was not Leah that the Dementors wanted to attack Leah, but Harry Potter.

As for the reason described by Ethan, Dumbledore didn't know if it was really the case, after all, the magical world didn't know much about the Dementor as a magical creature: it was a magical creature that was full of negative energy, able to feed on human pleasure, and capable of sucking human souls;

It will be banished by the Patronus Charm of the Divine Guardian, which is full of positive energy, but there is no effective way to kill it - speaking of which, Ethan used the Patronus to kill the Dementors, as if it were the first time in the wizarding world that such a creature had actually been killed.

The Ministry of Magic claims to be able to control the Dementors well, but the Ministry of Magic's alleged control is not credible from this incident.

"Anyway, these things were sent by the Ministry of Magic...... Isn't there a need for someone to be held accountable for this?"

“......”

Ethan's inquiry caused an eerie silence in the room, and Dumbledore finally shook his head helplessly: "The Ministry of Magic is to keep Hogwarts safe, after all, ......"

"Because Sirius?"

Lupin's expression changed slightly, but he stood quietly to the side, he was still a little confused about the current situation, he didn't understand what Ethan's identity was, and he wasn't ready to interject until he figured out the situation.

"Yes, we were all worried that he was going to hurt Potter. ”

"Hurt Potter?" Ethan shook his head, "He won't hurt Potter." ”

Ethan is sure of this, after all, he is an outsider who knows the follow-up plot. It's just that this statement will not be easily recognized, especially Lupin.

"Why are you so sure? What do you know?"

"I don't know much, but I know everything I need to know. ”

Sirius is the godfather of Harry Potter, and he was arrested in Azkaban for killing the Potters, who were Harry Potter's parents.

He was believed to be Voldemort's lackey, revealing his friend's hiding place and causing the Potters to die at Voldemort's hands, and after the Potters' deaths, Sirius was thrown into Azkaban without even any trial, and everyone considered him a sinner.

Before this moment, Lupin, including Sirius's former friend, thought so.

"Don't you think so?"

"No, because it's someone else who leaks the secret. ”

"It can't be!"

There are many magical spells in this world, and the Curse of Loyalty is one such spell, Sirius is considered a traitor by everyone, and no one speaks for him, because of the existence of such a spell.

In the presence of such a spell, there is no way to find the Potters except for the betrayal of the Secret Man, but everyone does not know that the Potters and Sirius have secretly changed the Secret Man after consulting with Sirius - and this is the traitor who betrayed the Potters.

Dumbledore didn't doubt the veracity of what Ethan said like Lupin, because he felt that Ethan didn't need to lie about this kind of thing at all, and even thought that Ethan would say this to them in return for the events of the previous school year.

"Do you know who really betrayed the Potters?"

Ethan took a sip of hot tea and muttered in his heart, 'The plot is going to end again...... but he didn't hesitate at all: "I also know that this person is hiding in Hogwarts right now." ”

"What?"

Not only was Lupin taken aback, but even Snape and Hogwarts were frightened.

The man who betrayed the Potters was undoubtedly Voldemort's minions, and that kind of person was lurking inside Hogwarts?

Who could it be?

Dumbledore couldn't think of anyone who would be Voldemort's subordinates, and he basically knew the details of these professors in the school, unless he joined Voldemort's camp later like Quirrell did two years ago, he shouldn't go unnoticed by himself.

"No, even if James and Lily secretly changed the secret person, this secret person must be someone we all trust, how many such people are there?"

"There aren't many. ”

Lupin's face suddenly changed, if it weren't for Dumbledore's presence next to him, and his fame was enough to reassure him, he even suspected that it was a conspiracy against him.

Because Jaime and Lily's friends are only himself and Peter Pettigrew, except for Sirius, and Peter Pettigrew is dead......

"You think I betrayed Jaime and Lily?"

"I'm not talking about you. ”

Ethan was speechless about the brain circuits of these people, and helplessly stretched out his finger and made a chopping motion.

"Could it be that if I cut off my finger and throw it in front of you, it means that I am already dead?" He spread his hands helplessly: "No one has ever doubted him, could it be because of Sirius, a ready-made back-stabber, so you take it for granted that the matter has been resolved?"
