The wizard in Hogwarts is unscientific

After listening to Sirius' loud roar, Andy was silent for a while, with the corner of his mouth twitching slightly.

Of course Andy doesn't believe him right away.

Andy analyzed the entire process of Sirius betraying Harry's parents and the entire process of his escape from Azkaban.

In fact, there is a possibility that Sirius may have been wrongly accused, but what is more, there are irrefutable facts.

"You are the secret keeper of the Chidan Loyalty Curse. After you were arrested, you never defended yourself."

Andy asked calmly: "How do you explain these two points?"

"I've heard something. You and Harry's father, James Potter, have a very good relationship. The two of you are almost inseparable. Before you betrayed them, James Potter might indeed let you do it. The godfather of profit."

At this point, Andy did not continue to ask, but patiently waited for Sirius's answer.

"I didn't betray them!"

Now that everything has been said, Sirius has no intention of concealing it anymore, "We have changed the secret keeper, and only four people know about it. Me, James, Lily...and that shameful traitor, Peter Pettigrew." !”

Andy raised his eyebrows.

If Sirius said it, then it was not Peter Pettigrew who was chasing Sirius, but Sirius who was chasing Pettigrew.

After thinking for a while, Andy asked: "So... Peter Pettigrew is still alive? How to prove it?"

"He's the rat!"

Sirius yelled, "I saw that newspaper, he was disguised as a Weasley mouse and he was following that kid called Ron Weasley!"

"Ha! Twelve years have passed and he is still like this, without any courage!"

Ron's rat?

Banban?

"Is he an Animagus too?"

Before Sirius could answer, Andy asked again: "Why did you change the Secret Keeper in the first place?"

Hearing this question, Sirius became decadent, and his tone was a little weak, "It was me... I suggested it! I was too ostentatious back then, and I was a sure target for Death Eaters."

"For better confidentiality, I propose to change the secret keeper to that mouse. He is very low-key and hardly attracts attention. As for me, I will continue to attract the attention of Death Eaters openly."

"did not expect……"

Sirius's tone was full of regret and hatred, "I didn't expect that mouse to turn to the mysterious man. He betrayed James and Lily's family."

"It's all my fault, I shouldn't have believed him!"

"I thought I could atone for my sins by staying in Azkaban, but then I saw that rat again. Their family won the Galleons jackpot, and it was even in the newspaper!"

At the end of the sentence, Sirius's tone didn't know whether he was thankful or mocking.

Andy: "..."

To be honest, Sirius's explanation was quite logical, but after all, these were just his words, and Andy couldn't trust him.

"I heard that Remus Lupin is also your friend?" Andy asked another question.

"Yes!"

Sirius understood what Andy meant, and he explained: "In fact, there was indeed a traitor on our side back then, and we didn't know who he was."

"Remus...Remus..."

Sirius hesitated, "Anyway, I suspected Remus was a traitor and couldn't believe him."

Is there something wrong with this person?

Andy thought for a while and said slowly: "So, there are only four people who know about you changing the secret keeper. And now, the only one who can prove your innocence... is the mouse, that is, the little one Peter Dwarf?"

"You thought he was dead, so you didn't defend yourself after being caught, and you tried to make up for your mistakes through self-punishment?"

"To be honest, I kind of believe you now!"

After hearing Andy's words, Sirius looked at Andy in disbelief.

He thought Andy wouldn't believe him.

After all, even if another adult came over and heard his words, he would think that he was defending himself.

Sirius originally thought that he would be very lucky as long as Andy could hesitate for a moment after hearing his explanation and not immediately send him to the hands of the Ministry of Magic.

He could take the opportunity to escape.

Or ask Andy to invite Dumbledore over.

"Yes! I kind of believe it."

Andy said expressionlessly: "Stupid Gryffindor, this is very much in line with your approach!"

Sirius:"……"

He swore that when he regained his freedom, he would definitely challenge Andy to a duel, three hundred times!

"I'm going back to investigate."

Andy glanced at Sirius and said, "You can rest here for a while! If I find clues, I will bring Dumbledore here with me."

Sirius' expression softened slightly.

Of course he won't stay here and wait for Andy. He plans to escape from here and then execute the traitor with his own hands.

Of course, if he couldn't escape, he would wait for Dumbledore here.

Then, Sirius saw Andy raise his wand.

?

There was a flash of white light, and Sirius completely lost consciousness.

"It's a bit troublesome!"

Walking out of the cave where the laboratory is located, Andy looked slightly troubled.

Sirius's explanation is actually very easy to confirm. As long as Ron's mouse Scabbers is found, he can prove whether he is lying.

But in this case, all the plans to 'infiltrate the Department of Mysteries' came to nothing!

There are also experiments on magical transformation...

"Actually... Sirius may not be needed!"

Andy suddenly thought: "The experiment of magical transformation can be to catch people in Knockturn Alley; the plan to infiltrate the Department of Mysteries can also be to change anyone at will."

"The biggest loss in the whole thing is probably the Ministry of Magic's bonus - a full 10,000 gold galleons. If Sirius attacked the Ministry of Magic, it would be 20,000 gold galleons."

"But compared to that, if you can gain Dumbledore's favorability, it's not a loss."

"Um……"

"I also need a house elf!"

Andy quickly hatched a plan again.

Sirius was originally chosen mainly because he could serve multiple purposes.

As long as he catches Sirius, he will not only save Andy a lot of trouble, but he can also take advantage of the opportunity to make a lot of money and gain prestige.

Since he was wronged, he had to be replaced.

"Dumbledore's favorability...is not bad either!"

Andy thought that since Dumbledore couldn't be put into the ring and carried with him, he could only increase his favorability and ask questions about magic at any time.

Snapped!

Andy apparated to the square in Godric's Hollow and sent a letter to Dumbledore at the Owl Post Office, explaining the matter simply.

Summoning the Fat Cat Patronus, Andy ordered, "If you see my principal, bring him here!"
