Became good friends with the Boy Who Lived

The summer vacation passed by inadvertently. On September 1st, after packing everything, Aries said goodbye to Selena and Ariana, and came to King's Cross Station alone with his luggage.

Since the Greene family lived not far from King's Cross Station, Aries was one of the first returning students to enter Platform 9 3/4.

Aris entered Platform 9 3/4 with an adult wizard. Aris looked at the wizard strangely. The wizard had a haggard face. Although he looked young, his gray-brown hair was mixed with white hair. He was wearing an old patched robe. Although it looked worn out, it was well-kept. He was dragging an old suitcase in his hand. A name could be vaguely seen on the suitcase: Remus Lupin.

Noticing that someone was staring at him, Professor Lupin did not act unnatural. Instead, he smiled gently at Aries, got on the train, and walked towards the last carriage on his own.

Aries paced after Professor Lupin and entered the last compartment of the last carriage. After Professor Lupin put away his luggage, he sat down by the window and Aries sat opposite him.

"Returning student?" Professor Lupin spoke, his voice tired. "What year are you in? Which house?"

"My name is: Aris Grindelwald," Aris said, "I will be a third-year student when I return to school, in Gryffindor College. I am very happy to meet you, Professor Remus Lupin."

Professor Lupin forced a smile and looked at the name vaguely visible on his suitcase. He said, "You are very smart, Aeris. The last name Grindelwald is not very common. Who is Geralt Grindelwald to you?"

Aeris said indifferently, "It's my grandfather, but please believe me, professor, I may not know as much about my grandfather as you do."

Professor Lupin smiled and said, "I am indeed very tired, Aris. It has been a pleasure talking to you, but I really need to take a nap."

"As you wish, Professor," said Aeris. "I will go and look for my companions, too."

Professor Lupin leaned his head against the wall of the carriage, and soon he began to snore softly. Aries also walked out of the compartment and considerately closed the door.

He greeted familiar classmates along the way and sometimes exchanged a few words, "Hey, Aries!" Draco poked his head out of a cubicle and greeted Aries.

"Drago!" Aeris said enthusiastically, "How was your summer vacation?"

"It's terrible!" Draco said in annoyance. "That Potter guy is really nosy. He made our family lose a house-elf. We have to do a lot of things ourselves, even though that house-elf has been working for our Malfoy family for generations."

"Don't blame him," said Aeris, "he just has a strong sense of justice."

"Hmph!" Draco snorted coldly. Someone seemed to be calling him in the cubicle. Draco hurriedly said, "Wait a minute..." and returned to his cubicle.

At a boarding entrance, Eris saw Hermione trying to move her luggage onto the train. Eris immediately went over to help, helping Hermione carry the luggage onto the train.

"Thanks, Aeris," Hermione said casually. "Which compartment are you in?"

"The last car," Aeris answered, and Hermione gave him a strange look.

"At this point, there are only a few empty compartments in the last few carriages," said Aeris.

"Excuse me!" Harry's voice came. Harry and the Weasley family also arrived. Aris helped Harry and Ron carry their luggage onto the train. Harry said, "Let's find a compartment. I have something to tell you."

"There's still room in the last carriage." Aeris said, and several people walked towards the last carriage of the train.

Along the way, just as Aries said, almost all the compartments were filled with students returning to school. When they were about to reach the last compartment, Ron yelled, "Ginny, don't follow us!"

Ginny glared at Ron and said, "You're such a good brother!" She looked into a compartment and went in.

Aries led the other three people into the last compartment of the last carriage. Professor Lupin was sleeping soundly in the innermost seat.

"Who do you think he is?" Ron asked.

"Remus Lupin!" Hermione replied.

"How do you know everything?" said Ron.

Hermione pointed impatiently at Professor Lupin's head, where his suitcase was placed. Ron smiled awkwardly and continued, "What do you think he's going to school for?"

Hermione rolled her eyes and said, "We are still short of a Defense Against the Dark Arts professor!"

After Harry put away his luggage, he closed the door of the compartment and slowly recounted to several people what Mr. Weasley and Mrs. Weasley had argued about last night.

In fact, recently an evil wizard named Sirius escaped from Azkaban. Sirius was once a sworn follower of Voldemort. People thought that Sirius escaped from prison in order to kill Harry and avenge Voldemort. The source of the Weasleys' argument was whether to tell Harry about this.

Hermione looked at Harry worriedly, "Don't look at me like that, Hermione," Harry said unnaturally, "Your eyes are really like Mrs. Weasley's. I'm not a child anymore. Don't forget, I escaped from Voldemort three times... Don't be like this, Ron, cheer up... I'm not a porcelain doll that will break at the slightest touch..."

"Have you figured out how to deal with an adult evil wizard?" Aeris said quietly, "I don't think they will be lenient just because you are a minor."

Facing the silent Harry, Aeris continued, "Courage is a good quality, Harry, but recklessness does not mean courage. Moreover, Sirius may not be coming for you. Don't do something stupid like actively looking for him before he stands in front of you."

A few people chatted for a while, and the witch who sold snacks opened the door of the compartment. A gentle voice came: "Do you need snacks? Dear children!"

Several people bought some snacks, and Ron said hesitantly: "Should we wake up this... uh... professor?"

Hermione shook Professor Lupin slightly and called softly: "Professor... Professor... wake up... Professor..."

But Professor Lupin seemed to have fallen into a deep sleep. After frowning slightly, he did not respond further.

"Let him sleep, dear!" said the witch who sold snacks. "I'm in the train control room. If he's hungry when he wakes up, just let him find me there."

Aries bought a lot of chocolate frogs and hid some of them for emergency use. While they were enjoying their snacks, it started raining heavily outside the train and the rain was getting heavier.

The door of the compartment was pulled open, and Draco walked in arrogantly. He glared at Harry fiercely and said sarcastically in a dragging tone: "Isn't this our righteous partner, the famous Mr. Harry Potter?"

"Drago, how did I offend you again?" Harry said helplessly.

"You are pretending to be innocent now, aren't you?" Draco said angrily. "We lost a house-elf because of you. I have not had a decent summer vacation."

It seemed that Draco's voice disturbed Professor Lupin's sleep. Professor Lupin made a meaningless humming sound in his throat. Draco looked at the sleeping Professor Lupin in confusion.

"Why is there a grown wizard on the Hogwarts Express?" Draco asked.

"We still want to know," said Harry. "I was impulsive, Drago. I did it in the heat of the moment. I really didn't consider the trouble it would cause you."

Harry handed the largest chocolate cauldron to Draco and stared at him earnestly. Draco took the chocolate cauldron and snorted coldly, glared at Harry and said, "I'll settle with you later." He turned around and left the compartment arrogantly, not forgetting to close the door.

Professor Lupin slept all the way as the train continued on its journey. The other people in the compartment changed into their robes tacitly, which was actually just putting the loose robes on the outside. For some reason, the closer they got to Hogwarts, the colder it felt.

Ron yawned out of boredom and muttered, "It's almost time..."

Before Ron could finish his words, the train vibrated and slowly stopped. Ron said, "We have arrived..."

Just as a few people stood up, the lights in the compartment suddenly went out without any warning. It was already pitch black outside the window and the surrounding scenery could not be seen. Messy footsteps were heard in the corridor of the carriage.

"Luminescent flashes~" Two voices sounded at the same time, and Aeris and Hermione each conjured up a ball of light, illuminating the dark compartment.

The compartment door was pulled open, and Neville stumbled in. Aeris quickly supported him. "Excuse me," Neville said, "I only saw the light here, so I wanted to come in and ask what happened."

"We don't know for sure, Neville," said Hermione.

Another figure flashed into the compartment, and Neville let out a cry of pain, "I'm sorry, Neville..." It was Ginny's voice, she seemed to have stepped on Neville's foot.

Just as Harry was about to walk out of the compartment, he bumped into someone. Harry helped the person up. It was Draco, who looked terrified.

"Run...Potter...Run..." Draco said in a trembling voice, "Dementors..."

Before Draco could finish his words, a tall, thin figure in a wide cloak just... slid over. Yes, not floating, nor walking, but the hem of that thing's robe slid over along the ground.

The face of this humanoid creature was hidden under the hood, with two large, bony hands... er... it would be more appropriate to say claws. The large, bony claws were covered with horrible scabs. Its head, hidden under the hood, turned, as if it was looking at everyone.

There was a suction force coming from under its hood, and the temperature in the car suddenly dropped below freezing. Frost even began to form on the window glass.

"Potter... Potter..." came Draco's terrified voice. Aris looked over and saw Hermione curled up in the seat holding Ginny. Ron was standing in front of them, but he was also trembling with fear. Harry collapsed on the ground and seemed to have lost consciousness. Draco slumped beside Harry, holding Harry's head and shaking it. He didn't look much better than Harry.

Neville beside Aeris was also shaking. "Expecto Patronus~" a slightly tired voice came, and the silver light dispelled the cold and blocked the Dementors outside the compartment door. Professor Lupin finally woke up and said, "We can't hide Sirius in his robes. Leave, guards of Azkaban."

But this Dementor had no intention of leaving. It turned its head towards the unconscious Harry, as if it wanted to get closer. More and more Dementors gathered here. Aris took a quick look and saw that there were about a dozen of them.

Aris raised his wand, and the scene of being adopted by the Greene family kept appearing in his mind. "Expecto Patronus~" Aris chanted the spell slowly and firmly.

An inspiring tiger roar sounded out of nowhere, and the shadow of a huge silver tiger slowly solidified. The tiger roared again, and the coldness in the carriage was completely dispelled. The tiger stared at the Dementors fiercely, roared again, and then pounced towards them.

More than a dozen Dementors fled in panic. Tiger wanted to chase them, but Aeris said, "Don't chase them. We need you here..."

The tiger roared unwillingly and then paced slowly around Aeris. Everyone gathered around Harry. After a long while, Harry finally opened his eyes with difficulty. When he saw people's worried expressions, his eyes were confused.

Without hesitation, Aries stuffed a chocolate frog into Harry's mouth and said, "Chew!"

Aris distributed the chocolate frogs to others, then tore open the package of a chocolate frog, stuffed it into his mouth, and chewed it in big mouthfuls.

Professor Lupin looked at Aris in surprise and said approvingly, "You really don't look like a third-year student, Aris."

"Everyone get ready," said Professor Lupin. "After the train starts, we should be able to reach Hogwarts in about ten minutes. I'm going to the control room." After that, he left the compartment.

After a while, the train started to move slowly.
