Sure, here's the translation:
In the compartment in front of him sat a red-haired boy.
"Come on in." The boy said, "There's no need to be shy—my aunt asked me to take care of you. Come on, put your suitcase here first."
Harry walked in, letting the boy help him put his suitcase aside.
"By the way, I'm Gareth." The boy said, "Gareth Weasley. I hope you and I both get sorted into Gryffindor."
"Why not Slytherin?" Harry asked, as he had once done.
Gareth chuckled and explained to him: "I imagine you wouldn't want to be sorted into Slytherin either. It's mostly pure-blood or mixed-blood families there, a Muggle-born like you wouldn't be sorted into Slytherin."
"I see." Harry nodded, then said to Gareth: "I don't want to go to Slytherin either because I really dislike the headmaster with the surname Black…"
Upon hearing this, Gareth showed the look of seeing a kindred spirit.
He reached out, firmly shook Harry's hand.
"From now on, you're my true brother, Harry!" he said.
As they spoke, the lady pushing the snack trolley slid open the compartment door.
"Want some snacks, kids?"
Harry was about to dig into his pocket but suddenly remembered that at the start of his first year, he didn't have any money at all.
Payment?
The only Golden Galleon, leftover from buying clothes and books, was meant to be saved.
"I'll take a bit of everything." Gareth said, after fetching a few Sickles and handing them to the trolley lady: "Let me think… I'll have two Chocolate Frogs, I really like them, ma'am."
After the vendor left, Gareth laid out the purchased snacks in a row on the seat.
"Try these, Harry." Gareth grinned and said: "Hey, I really like eating snacks, always can't help buying and eating them—can't finish them all, it'd be a shame to waste, why not help me out with them?"
"Thanks." Harry nodded.
He didn't quite know what he should do now, but following the memories from back then couldn't be wrong.
"Blow-Me-Up Super Bubblegum?" Harry picked up a piece of bubble gum, looking towards Gareth who was unwrapping something.
"Oh, it's a rather magical candy," Gareth put down the Licorice Wand in his hands and said, "it lets you blow bubbles of bluebell-colored, floating in the room for days without bursting—you'll see when you try it."
Harry unwrapped it, popped the gum in his mouth.
Surprisingly, he found he could actually taste the flavor?!
Even now, he felt somewhat uncertain, is this really a memory?
"What are these?" he picked up a pack of Chocolate Frogs and asked Gareth, "They're not real frogs, are they?"
"What?"
Gareth looked up, saw the Chocolate Frog in Harry's hand and continued: "Oh, you wouldn't know, Chocolate Frogs come with picture cards, you can collect them, they're of famous witches and wizards. I've got around five hundred of them, just missing Agrippa and Ptolemy."
Harry opened a Chocolate Frog, took out the card, it portrayed a man's face wearing a tall Magic Hat, holding a long wand, looking quite kind.
Below the Chocolate Frog card, it read: Merlin.
The most famous wizard of all time, sometimes referred to as the Magic Prince, a member of King Arthur's court.
"Oh, it's Merlin." Harry said.
"Don't tell me you've never heard of Merlin!" Gareth looked amazed: "Merlin's beard… But I suppose it's expected, given you're Muggle-born, not knowing Merlin is understandable…"
Just as Harry was about to say something, they found the compartment door being swung open.
Standing at the door was Cassandra—not the first-year Cassandra, but the one matching the age of the Cassandra outside.
Seeing third-year Harry, Cassandra was mildly surprised too.
She clearly hadn't anticipated this Harry sitting here in the carriage.
"Potter?" she asked uncertainly.
At the same time, she was ready to flee, on guard.
She naturally worried it was a disguised Death God opposite her, but didn't want to give up any sliver of hope—what if it's Potter?
"Cassandra!" Harry hurriedly stood up, hesitated a bit looking at Gareth still introducing Merlin to the air: "Um, should I finish playing the part of who I am?"
Seeing Harry like this, Cassandra breathed a sigh of relief.
The person in front was none other than Harry himself.
Death God could imitate Harry, but Death God couldn't possibly mimic this side of Harry.
"So, you're a third year now?" Cassandra raised her head, her gray eyes fixated on Harry.
"Yes." Harry nodded, "I've been searching for you all this time. Luckily, I finally found where you've been sleeping—"
In English, the words "you" and "you all" are the same, so Cassandra only presumed Harry meant "I've been searching a long time for you."
Count yourself kind enough, she thought, not going to find that Grindelwald family's sneaky cat first.
Hah, if I discover you went for that sneaky cat before me, you're done for, Potter!
"So what's happening now?" he also said: "What should I do to awaken you from sleep—and I recall you mentioned Death God earlier? What's that got to do with Death God?"
"As I said, I tried to break the boundary between life and death, so Death God isn't very happy, wanting to drag me into Hell…"
Cassandra said this so lightly, as though she was being chased by a puppy instead of being pursued by Death God.
"Potter, I don't think you should get involved in this mess." Cassandra said, her chin lifted again: "If you lend me help, Death God would relentlessly hunt you."
"To hell with whatever Death God, I don't care." Harry cursed: "I only know, I want to take you back now!"
Cassandra flashed a relieved smile.
"I warned you, Potter." She said smugly: "Yet now you have to play your role correctly—I don't want you exposing flaws, getting our location traced by Death God, understood?"
"Alright then." Harry sat back down.
After answering Gareth's question, he looked up asking: "What's this anyway? I don't think this is your memory…"
"Certainly not my memory, silly Potter." Cassandra's gray eyes showed disdain: "This belongs to the happiest memory of a silly Little Giant like you—"
For some reason, when Cassandra used to scold him disdainfully before, Harry felt a strong urge to fight back.
But after two years without Cassandra's scolding, upon hearing it suddenly, Harry felt an unexpected sense of "that's the familiar feeling"…
"The happiest memory?" he asked.
"Yes." Cassandra answered, "I don't know where the key point is but we'll experience each other's happiest memories, searching for the hint to escape the dream—looks like this is your happiest memory, Potter."
As she said this, Cassandra's eyes passed a hint of playful amusement.
She leisurely looked outside the compartment because… her first-year-self was about to appear soon.
It didn't keep her waiting long, just after Harry and Gareth finished discussing Slytherin, the compartment door opened.
Harry turned his head, standing at the door was a proud-looking little girl.
It was the young Cassandra Malfoy.
Older Cassandra stood aside, a light smile in her eyes, watching her eleven-year-old self.
However…
The memory abruptly stopped at this moment.
(Only four thousand today, had a family gathering eating late, couldn't very well leave early…)
