I was expelled from Hogwarts?

Hooked nose, black hair, walking like a bat... Even after twelve years of absence, Sirius still recognized Snape at a glance based on these features alone.

"Oh, Severus, it's good to meet you. My dear old classmate."

Snape ignored Black's greetings, looked at him with an almost contemptuous smile on the corner of his mouth, and said:

"I'm surprised that you're still alive, Black... I thought you'd have been turned into a pile of bones in Azkaban."

"I'm disappointed, Severus." Sirius smiled, "It's a pity that I didn't die under the kiss of the dementor."

"You stupid lions of Gryffindor are indeed hard-pressed, just like your friend Pettigrew Peter, who was supposed to die twelve years ago, but he has survived until now."

The big mouth under Snape's hooked nose twisted into a mocking smile, and he said in a strange way:

"I heard that you spent twelve years in prison for him. Wow, what a picture of brotherly love, worthy of being a close friend, really warm..."

"I admit that I was wrong and believed in the wrong person." Sirius didn't laugh anymore, he said deeply and coldly:

"I'll kill Peter, I swear I'll kill him...to avenge James and Lily."

"I doubt it." Snape dragged his voice, and said slowly: "You were played around by him back then, will it change now?"

"Or is it that Azkaban has the ability to increase IQ? In that case, I will probably believe that you, a stupid but proud idiot, can do it."

"You've been clever since you were a child!" Sirius pursed his lips tightly, suppressing his anger and said:

"Joined a group of evil Slytherin gangs when I was in school, and followed them to Voldemort after graduation... When Voldemort fell, he saw the wind and turned to this side."

"You're really not stupid, Severus...you know what's best for you, always on the stronger side...I really admire your wisdom."

"Those friends of yours back then were far inferior to you... More than half of them died on the battlefield, and a small half entered Azkaban, unlike you...but they stayed in Hogwarts to enjoy themselves."

Sirius was within two palms of Snape's face, and each could feel the other's breath.

"I don't know why Dumbledore and Rove are willing to believe in you and think that you have been transformed, but I understand you..."

"Sense of responsibility, sense of honor, friendship, which one do you have?" Sirius asked softly, his eyes lingering on Snape's face.

"Hmph, don't bother thinking about it, we both know the answer. Severus, you are a wise man, but you are also a coward... a coward!"

Snape's eyes widened suddenly, with hatred and the most downright contempt in them.

"Yes, I'm a coward, not as good as you, great warrior. But, Black..."

Snape retorted in a bitter tone: "At least I'm not stupid enough to temporarily change the secret keeper and kill my best friend."

Sirius felt the blood rushing straight to his face.

For a moment, Rove thought that the two of them were about to take out their wands and start fighting. After all, the two sides were too good at hurting each other, and they jumped repeatedly on each other's sensitive points.

As expected of the best "friend", he always knows what to say to break the opponent's defense.

But at this moment, Professor McGonagall appeared, she came over, pursed her lips, and asked sternly:

"What the hell is going on? What are you two doing here?"

"It's nothing, Professor McGonagall." Sirius took a step back, panting heavily, as if he had just finished a long-distance run, "It's just two old classmates catching up... talking about the Dark Lord and his lackeys and other topics. "

"Speaking of dogs." Snape said with a sneer on his lips:

"I received a letter not long ago. Mr. Malfoy claimed that Potter took a big black dog on the train and let the dog bite him...isn't that right, Mr. Malfoy?"

"Yes, sir." Malfoy in the crowd had a blush on his face, and he said excitedly, "Mr. Scamander can testify that he also gave me medicine to treat rabies."

Rove was about to slip through the gate with Shirley, Hermione, and Neville, so he had to stop, and he replied:

"Oh, yes, that's right, I did heal Malfoy's wounds, but I don't know who bit them."

"It's okay, there must be other witnesses." Snape showed a sly smile, with a smug look in his eyes and said:

"I remember Mr. Potter, who is still under probation. If this is confirmed, Professor Dumbledore may have no reason to keep you."

"Professor Snape, I must remind you that I became the dog." Sirius said with a blank expression:

"Malfoy took his two little followers and used school violence against Harry. As a teacher, I just gave a small punishment. This matter has nothing to do with Harry."

"Punishment?" Professor McGonagall exclaimed: "Professor Black, we never use magic to punish students, let alone... bite students as punishment!"

"I know... point deduction and confinement." Sirius shrugged and said:

"Professor McGonagall, I am a professor for the first time, and I will be familiar with these rules in the future, and I will be more measured when punishing students.

I will also study hard with Professor Snape, and learn from his excellent method of punishing Gryffindor students. "

Malfoy didn't expect that he was bitten by the new professor. He looked up at Black and muttered something, some of the words were clearly heard, "my dad".

"You can go back and tell your father, but it's better to tell your mother... Narcissa Black Malfoy." A faint smile appeared on the corner of Sirius' mouth.

"You tell her that when my cousin was in Azkaban... I missed her and her husband very much. Bella and I are both in prison, so it's a pity that we didn't see her."

Malfoy's slightly flushed face turned pale again.

Snape snorted coldly, didn't bother to pay attention to the mean-mouthed mad dog, turned around and threw his sleeves, and strode away.

"All the students go in." Professor McGonagall urged: "Hurry up, the first-year students are coming soon!"

Only then did the students reluctantly walk towards the auditorium.

Sirius walked up to Professor McGonagall, and he said apologetically, "Sorry, Professor McGonagall, I caused you trouble on the first day."

Professor McGonagall was stunned. The Sirius in her memory would never apologize like this, and would always fly freely, like a collection of Weasley twins.

But Professor McGonagall immediately realized that the two of them hadn't seen each other for twelve years.

For Sirius, it was twelve cruel years, and the years left their marks on him and changed his character.

McGonagall looked up at Sirius carefully, looking at this student who once had a headache.

When he was a student, Sirius was extremely handsome, but now he has a short stubble covering his chin and cheeks, and there are a few touches of silver in his black hair, making him look a little bit old.

In fact, he was just in his early thirties!

A sad smile appeared on the corner of Professor McGonagall's mouth. She patted the middle-aged man's shoulder and said softly:

"No matter what, it's good to come back...children, you are welcome home."

Sirius wanted to say something, but at this moment, his eyes were red and swollen, and his lips trembled so that he couldn't speak. He tried his best to endure, but he couldn't stop the tears from streaming down his face.
