The Earth revolves around the Sun, and the Moon revolves around the Earth.
Whether in Muggle or wizarding households, this was considered basic knowledge.
Harry and Ron stared at Sherlock as if he'd grown a second head.
Until now, Sherlock had always struck them as someone who knew everything—a walking encyclopedia who could deduce even the unknown from observation and reasoning.
But this?
Hermione couldn't hold back her disbelief. "You—you seriously didn't know the Earth orbits the Sun?"
It was hard to imagine that in the 20th century, someone could be unaware of such a fact.
"You all seem surprised?" Sherlock chuckled at their expressions. "Even if I did know it, I'd make an effort to forget it."
"Forget it? But why?" Hermione asked.
Sherlock tapped a finger against his temple.
"To me, the brain is like a hard drive. It only makes sense to store what's useful.
"Most people stuff their minds with useless junk. The result? The truly valuable information gets squeezed out. When they finally need to learn something, they find it difficult."
"But that's… the solar system! It's fundamental science!" Hermione exclaimed, still wide-eyed.
"So what?" Sherlock replied impatiently, his tone bordering on rude.
"You say we revolve around the Sun. But whether it's the Sun, the Moon, or we're spinning like teddy bears around a garden—it has no impact on me or my life, does it?"
"So please, don't torture me with your grand ideas."
Hermione: Σ(°△°|||)︴
Harry and Ron exchanged glances.
He kind of makes sense, and I… don't even know how to argue with that.
Sensing he'd been a bit harsh, Sherlock softened his tone.
"Apologies. That was rude of me. Still—not a big deal. From today onward, I will remember it… at least until Astronomy becomes an elective."
Hermione: ￣△￣
That day, the first-years' understanding of Sherlock deepened yet again.
Hermione came to a new realization:
He's nothing like me after all!
After Thursday's Transfiguration and Charms classes, Friday—the final school day of the week—arrived.
"Having class with Slytherin is bad enough. But Potions with them? Absolute nightmare!" Ron groaned.
According to the schedule, Gryffindor first-years had double Potions every Friday with Slytherin.
Which meant every Friday felt like Black Friday to them.
"Snape's the Head of Slytherin. Everyone says he favors his own," Ron grumbled, even losing his appetite as he poked dismally at his breakfast.
"Professor Snape?" Sherlock and Harry echoed in unison, a vivid image forming in their minds:
Oily black hair, a hooked nose, sallow skin—distinct and unpleasant.
Sherlock had committed the image to memory through observation.
Harry had an additional reason.
"Sherlock… at the Welcome Feast, Professor Snape was staring at me…"
Harry was just about to share the incident in detail when suddenly—
A hundred or so owls swooped into the Great Hall.
Among the fluttering feathers and scattered letters, a beautiful snowy owl flapped down between Harry's jam jar and sugar bowl, dropping a small note onto his plate.
"Hedwig?" Harry blinked.
He was surprised. So far, the birthday gift from Hagrid—his beloved owl—hadn't brought him anything.
Unlike Sherlock's owl, Watson, who regularly delivered intriguing items or notes.
"It's an invitation. Hagrid wants to have afternoon tea with you," Sherlock said casually without looking up.
"Wait—Sherlock, did you learn some kind of spell from Professor Flitwick to read through paper now?" Ron asked jokingly, then laughed at his own absurd idea.
But his laughter died as he noticed Harry's face. Harry was staring at the note in shock.
"Don't tell me he got it right again…"
Harry nodded and slid the note over.
Written in messy scrawl were the following words:
[Dear Harry,
I know you've got Friday afternoon free. Would you like to come over for a cup of tea around three o'clock?
I'd love to hear how your first week went.
Let Hedwig bring back your answer.]
—Hagrid
Harry and Ron looked at each other.
Even after seeing it happen again and again, Sherlock's uncanny deductions still amazed them.
"Bloody hell! How did you figure that out?" Ron asked.
"Figure what out?" Sherlock replied mildly.
"I mean… how did you know it was from Hagrid? And that it was an invite for tea?"
"I don't have time for small talk," Sherlock said curtly, in the same sharp tone he'd used with Hermione earlier in the week.
But before Ron could retort, Sherlock added with a smile:
"Forgive my rudeness—you interrupted my train of thought. But it's all right now.
"Let me ask instead—you couldn't tell the letter was from Hagrid?"
"Not before opening it."
"Well, recognizing what it is is easy. Explaining how I knew—that's the tricky part.
"It's like proving one plus one equals two. It's obvious to us both, but still complicated to prove in technical terms."
Seeing Harry and Ron's eager expressions, Sherlock decided to elaborate:
"I saw Hedwig flying toward you from a few tables away. She had a note tied to her leg—obviously, someone had written to you.
"The Dursleys definitely wouldn't write, and you don't know many people at Hogwarts yet. Most of your classmates eat and study with you. They wouldn't bother with owls.
"Hedwig usually begs you for toast whenever she arrives. Today, she didn't—so someone already fed her.
"So who at school has the means to feed her, a connection with you, and a reason to send an owl?
"The only one who fits all those conditions… is Rubeus Hagrid.
"As for the letter's content—well, since he brought you to Hogwarts, it's only natural he'd want to check in.
"And since Friday afternoon is the only free slot on our timetable, it's easy to deduce he's inviting you for tea."
"Brilliant!"
"Absolutely brilliant!"
Harry and Ron couldn't help but shout, earning puzzled glances from nearby students.
