I Swung a Sword at Hogwarts

"You all saw it, didn't you? That's Professor Lockhart's real teaching ability."

"Oh, come on, Hermione, it was obviously John who was teaching us. Lockhart didn't even take out his wand."

After Defense Against the Dark Arts class ended, Hermione rushed to find Harry and Ron to defend Lockhart's name.

But Ron was even more convinced that Lockhart was a fraud—throughout the entire class, the man hadn't even pulled out his wand.

If anything, it was more like John was the one teaching.

When Neville failed to cast the Levitation Charm, it was John who used Transfiguration to subdue the troll.

Lockhart? He had cowered behind the podium, scared out of his wits.

"Hmph, but that class went really well, didn't it?" Hermione tried to argue back, though she was starting to be convinced herself.

Watching her idol fall off his pedestal left her feeling conflicted.

Ron shrugged nonchalantly. "If John keeps teaching the classes, I've got no problem with Lockhart being there."

Harry watched the two of them argue, but his mind was on something else—the voice he'd heard while helping Lockhart answer fan mail on Saturday.

Because of the curse-flinging fight between Ron and Malfoy, both he and Ron had been assigned detention.

The good news? Malfoy's overprotective father hadn't stormed into Hogwarts over it. Rumor was that John had smoothed everything over.

That made Harry feel very grateful to him.

Just then, Filch's angry roar echoed through the corridor.

The Weasley twins giggled nearby. Frog brain matter was smeared all over the walls, driving Filch into a furious frenzy.

Being a Squib, he had no magic and had to clean everything by hand.

It didn't take a genius to figure out who was behind the prank. Percy, ever the stickler, marched up to lecture the twins with a stern face.

"You shouldn't be playing pranks like this."

"Oh, come on, Percy."

"No—call me Prefect."

"Maybe you'll get into the Ministry someday."

"Yeah, you'd fit right in with all the other dull and uptight people."

Fred and George fired back in perfect rhythm, leaving Percy fuming.

Percy was the odd one out in the Weasley family. Though Mrs. Weasley was proud of him, his serious demeanor didn't fit in with the rest of the household.

None of the other Weasleys would be caught dead reading a boring book like How Prefects Gain Power.

Still, Percy was determined—he wanted authority.

That's why, even though Lockhart's teaching was terrible, Percy still showed him the utmost respect.

In the end, family ties won out. He left with a warning, tail between his legs.

Fred and George made faces at his retreating back. Even Ron couldn't stand his older brother at times.

The twins may have teased him constantly, but they never acted like Percy—so rigid and high-and-mighty.

Percy didn't just feel out of place in the Weasley family—he felt like an outsider even in Gryffindor.

In Gryffindor, poor grades were tolerated. But having no friends or sense of humor? That was unforgivable.

"John, you were right. I told Father not to come to the school. Next time I see that Weasley, I'll make sure he's crying."

Over in the Slytherin common room, Malfoy proudly told John how he'd stopped Mr. Malfoy from interfering.

After being ambushed by Ron on Saturday, Malfoy had been ready to demand that the Weasleys be expelled from Hogwarts.

John frowned and gently told him, "Draco, don't act like a child. A powerful wizard doesn't hide behind his father. You can fight back with a curse—but never give people a reason to look down on you."

That advice had changed Malfoy's mind. He'd fired a curse back, and honestly, it had felt more satisfying than letting his father handle it.

By retaliating, both sides became equally at fault. If Mr. Malfoy had shown up, he probably wouldn't have gotten what he wanted anyway.

Daphne ran up to John with sparkling eyes and a playful smile. "You were amazing. That Transfiguration in class was perfect! Where on earth did you get a troll?"

"Oh? That was courtesy of Professor Lockhart."

John kept up appearances for Lockhart, trying to preserve his image at least a little. No need for everyone to completely doubt him.

But Daphne wasn't stupid. She scrunched her delicate nose and said with irritation, "Yeah right. He's not capable of that. Ugh, I don't get why my mother likes him so much."

John just smiled and didn't say more.

The "troll" had actually been a Boggart in disguise.

Boggarts took the shape of whatever frightened someone the most, but their actual power wasn't very high.

Even if they turned into a troll, they were probably only half as strong as a real one.

By using Occlumency to project a specific fear—a troll—and then stepping forward, John had made the Boggart transform into exactly what he wanted.

He remembered in Harry's third year, the Defense professor had also brought a Boggart to class.

Of course, that professor taught them how to defeat Boggarts—not how to use them.

Lockhart's actual abilities weren't much, but the stories in his books—stolen or not—contained valuable knowledge.

If followed correctly, the instructions weren't as useless as some critics claimed.

Unfortunately, Lockhart himself didn't seem to understand this.

Under John's guidance, their curriculum avoided practical spells unless absolutely necessary.

For every year except the second, classes focused more on theoretical applications drawn from the books.

Defense Against the Dark Arts centered around magical creatures, protection against dark magic, and appropriate countermeasures.

Handling this year's content would be relatively easy.

After being named Lockhart's assistant, many students began to see that John was different from them.

Even Professor McGonagall praised his Transfiguration as being at a senior student level—something that made all of Slytherin proud.

And thanks to Lockhart's favoritism, Slytherin's hourglass surged ahead in house points.

The other three houses were left far behind, and Slytherin walked with their heads held high.

"George! Fred!"

Percy's furious voice echoed in the hallway.

John exited the Room of Requirement just in time to see the two Weasley twins sneaking back toward the Gryffindor Tower.

Percy was storming down the corridor, having caught a couple of students out past curfew.

One glance was all it took—those flaming red heads were unmistakable.

But instead of catching the twins, Percy found himself face-to-face with John from Slytherin.

"I ought to give you a warning. I won't deduct points, but you are breaking school rules," Percy said, straightening his glasses and smoothing his perfectly tidy robes—a stark contrast to Ron's sloppy appearance.

He spoke rigidly, by-the-book.

John shrugged, then suddenly had an idea.

"Percy Weasley, come to think of it, we've barely spoken before."

John had always found the Weasley family memorable.

Aside from the two who had already graduated, Percy had the lowest presence.

But you couldn't deny that Percy was impressive—he'd earned twelve O.W.L.s, the mark of a classic overachiever.

Some even suspected that if it weren't for family tradition, he might have ended up in Ravenclaw.

All Weasleys were sorted into Gryffindor. The Sorting Hat probably didn't want to break the pattern.

The entire Weasley family disliked Slytherins instinctively—but this was John Wick, the boy who had saved the Trio.

Percy frowned slightly, then politely declined, "Sorry, I still have to help the professors patrol…"

"If that's the reason, you don't need to worry."

John gave a small smile and said casually, "Would you be interested in having a cup of tea in the Defense Against the Dark Arts office?"

He spoke as if inviting someone to his home, so naturally that Percy was a little taken aback.

Lockhart might be unreliable, but he was still a professor—and John sounded far too relaxed.

Then Percy remembered John was Lockhart's assistant.

Relaxing his frown, he nodded. "Alright, but only for a little while."

"That's more than enough."

John smiled, though his thoughts had already turned to something else.

If there was one unforgettable twist in the Harry Potter series, it was how one loyal Dumbledore supporter in the Weasley family eventually turned his back and sided with the Ministry.

That person was Percy, who thirsted for power—and that made him one of the few characters John remembered clearly.

He recalled how Percy rose through the Ministry ranks, even going so far as to sever ties with his family for the sake of ambition.

And that kind of ambition was exactly what John needed.

A new idea began to form.

Maybe he could recruit Percy Weasley.

After all, the connections John now held were incredibly valuable.
