Lupin looked at Evan suspiciously, he didn't know why the boy in front of him was outside the castle at this time, it obviously didn't make sense. He wasn't going to delve into it though, and just like him, everyone had their own secrets.

In fact, after more than two months of continuous contact, Lupin had a very good impression of Aven.

In his own class, the other party always answers all the questions at the first time, and it can be seen from the several homework assignments he assigns that Evan has a very deep understanding and unique insights about Defence Against the Dark Arts.

Lupin hadn't seen such a good young man in years, not to mention that Evan and Harry had a very good relationship, just like he had with James Potter, Peter Pettigrew, and Sirius Black.

Lupin felt distressed at the thought of Blake, and he still couldn't believe that the other party would betray Jaime and join Voldemort, who were once clearly best friends.

He shook his head, maybe he had been looking at the wrong person all along.

Blake was also very good back then, but he chose to betray in the end, the smarter people are, the more they account for the gains and losses, and friendship is just a commodity that can be exchanged at any time in their eyes.

So will this boy in front of him, like Blake, betray his friends for his own interests?!

Lupin looked at Evan carefully, hoping to see something from it.

The next second, his eyes widened suddenly, and he seemed to see a familiar figure in the grass opposite Aven.

The tip of his wand emitted a bright light and flew into the grass, leaving nothing inside.

Is it a delusion?

Lupin breathed a sigh of relief, he was now conflicted.

On the one hand, he wanted to see Blake ask the whole story clearly, and on the other hand, he was afraid to see the other party, afraid that Blake would tell him how he had betrayed James and Lily to Voldemort.

Lupin doesn't remember how many times he's been awakened by such nightmares.

Twelve years had passed, and he had been blaming himself for not discovering Blake's true colors earlier, so that he had the opportunity to betray Jaime and eventually kill Peter Pettigrew, all of which was his fault.

Lupin had thought that the guilt would stay with him for the rest of his life, but Black escaped from Azkaban, and everyone said that he had escaped with the intention of killing Harry, the only son he had once been a close friend of.

Lupin must not let this happen again, which is why he accepted Dumbledore's invitation to return to Hogwarts to teach. He wants to protect Harry, and maybe he can catch Blake himself and give an account of what happened back then.

Lupin took a deep breath, now was not the time to think about these things.

"Aven, you should go back to the Great Hall and stay with the others. Lupin took two steps forward, and then he came to a sharp stop.

He saw that the grass in the grass opposite Evan was crushing in one direction, there was indeed something there just now, he was not mistaken, it must be Sirius Black's Animagus, he had seen it countless times, and he would never forget it in his life.

The boy in front of me had contact with Blake, just a coincidence, or

When Evan saw Lupin's expression, he knew what he was thinking, it was really difficult enough, he didn't know how to explain it to the other party.

However, he didn't have to worry about it right away.

Just as he hesitated, something crawled out of the grass, and Lupin apparently heard the sound as well, and another bright light flew over. It was Crook Mountain, startled by the sudden light, and slammed into Aven's arms.

"Professor, I came out looking for this cat, it's my friend Hermione's pet, I just saw it run out of the castle, I was worried it would have an accident, so I followed. ”

Evan didn't know if Lupin would believe his casual excuses, and Lupin looked at Crookshank for a moment, with a relieved expression.

The two men returned to the castle, and they had just turned the corner of the foyer when they saw Dumbledore and Snape standing outside the Great Hall, talking about something.

"The whole castle was searched, and no trace of him was found. Snape whispered.

"Very well, Severus, I didn't really think Blake was going to stay. Dumbledore said calmly.

"But there's one thing I have to report back to you. Snape squinted, "We have a teacher who has been missing during the time we have been in the castle, the same person I told you before. ”

"What do you want to say, Severus?"

"I mean, how Blake got into the castle, do you have any insight into that, Headmaster?" said Snape.

"Many, Severus, every one is possible. ”

"Do you remember our conversation, just before the semester began?" Snape said in a low voice, clearly not wanting others to hear it.

"Remember, Severus. Dumbledore's voice had something like a warning.

"It's like、It's almost impossible, Blake can't get into this school without internal help, especially since that person is nowhere to be seen now, you know what I mean, I did show concern, before you accept your fate"

"I don't believe there's a single person in this castle who would help Blake in. Dumbledore said, his tone making it clear that the matter was over, so Snape did not reply.

The man Snape suspected was obviously Lupin, and Evan looked back and saw that Lupin was calm, as if he hadn't heard what the two men were saying.

"Severus, I must go to those Dementors," Dumbledore said, "I said we'd let them know when we searched them." ”

"Are they going to help?" said Snape.

"Oh, yes," said Dumbledore coldly, "but I'm afraid that as long as I'm headmaster, they'll never be allowed to cross the threshold of the school." ”

Evan saw Dumbledore walking towards the foyer, and when he saw himself and Lupin, he was slightly stunned, and Snape followed.

"Are you eavesdropping on our conversation?" Snape's gaze wandered over the two men, and finally locked onto Lupin with a look of hatred.

"Professor, we don't"

"Be careful when you make up lies, Mason!" Snape turned his gaze back to Aven, "I have to warn you that you should be sleeping in the Great Hall right now, as ordered by the Headmaster, instead of going out of the castle and doing something sneaky with someone you don't know at all. ”

"I" Evan was speechless, Snape and Dumbledore were more difficult to deal with, and he hurriedly repeated his reasons for going out to Crookshank.

"For this stupid cat, Gryffindor deducted ten points. Snape said in disgust, "Now go to sleep in the Great Hall, that's where you should be." ”

Evan hurried towards the Great Hall, and when he was about to enter, he looked back to see Dumbledore, Snape, and Lupin still standing there, not knowing what they were talking about.
