"Exactly," Stan said, still rubbing his chest. "Exactly. They say he was real tight with You-Know-Who… anyway, little Harry Potter took care of You-Know-Who back then."
Harry quickly smoothed his fringe down over his scar.
He searched for anything that might calm his nerves, and—almost like magic—the most reassuring wizard in the world was sitting right in front of him.
Sean quietly lifted his head and met Harry's gaze, then glanced at Stan's back.
Stan, completely unaware, kept talking.
"All of You-Know-Who's supporters got rounded up, right, Ern? After he disappeared, most of 'em knew the game was over and kept their heads down. Except Sirius Black. I heard he figured once You-Know-Who came back, he'd be second-in-command.
Anyway, they cornered him on a street full of Muggles. Black pulls out his wand and blows half the street to bits—one wizard and a dozen Muggles who just happened to be there. Terrible, innit? And you know what he did next?"
Stan dropped his voice to a dramatic whisper.
"What?" Harry asked.
"Laughed," Stan said. "Stood there and laughed his head off. When the Ministry backup showed up, he went quietly—still cackling like a madman. Must've lost it. Right, Ern? Completely mental?"
"Even if he wasn't mad when he went into Azkaban, he sure is now," Ern said in his low, gravelly voice. "I'd rather blow myself up than set foot in that place. Serves him right… after what he did…"
"They had a hell of a time covering it up, didn't they, Ern?" Stan went on. "Street blown to pieces, all those dead Muggles. How'd they explain it to the Muggles, Ern?"
"Gas explosion," Ern grunted.
"And now he's out again," Stan said, peering at Black's gaunt face on the front page. "Azkaban's never had a breakout before, has it, Ern? Can't imagine how he managed it. Bloody terrifying, innit? Can't picture anyone getting past those guards. Right, Ern?"
Stan had this odd habit they'd both noticed—he tacked "Ern?" onto almost everything, like the driver's grunt was the only thing that made his words official.
What he was saying was wild enough to chill Harry to the bone, and even Ern gave a little shiver.
"Change the subject, Stan. We've got two decent lads on board. I get the jitters just hearing about those Azkaban guards."
Stan reluctantly folded the paper away.
Harry leaned against the window, feeling lower than he had in months. He knew almost nothing about the wizard prison, but every time someone mentioned it, the same dread filled their voice.
The Knight Bus rattled on through the darkness, scattering bushes, trash cans, phone boxes, and trees.
Harry lay on the feather mattress, stomach churning with worry.
"Sean," he asked across the gap between beds, "the Ministry will catch Black again, right?"
"They'll try," Sean said after a moment.
"And if they don't? What'll he do?"
Sean didn't answer right away. He just looked at Harry with those bright green eyes, and Harry suddenly understood what the silence meant.
"Excuse me, miss—could we swap beds?" Harry asked the pockmarked witch whose bed was blocking him from Sean.
She grumbled but moved. Only then did Harry's racing heart settle a little.
Up close, he could see exactly what Sean was writing.
On the neat page was a sketch of a wizard raising a wand, the tip exploding with blinding white light—brighter than the Knight Bus headlights.
Below the drawing were the usual Green's Notes breakdowns of wand movements and pronunciation.
But the pronunciation and gestures were completely new. Harry had never seen anything like them.
"What spell is that… looks like Lumos, but…"
Harry didn't want to interrupt, so he whispered to himself.
"Blinding Light Curse," Sean said, quill pausing.
"Oh—sorry to bother you, Sean… but what's a Blinding Light Curse?"
Harry's voice cracked.
"The first spell I've reshaped," Sean explained, still writing. "I took Lumos and changed the inner order behind it—from 'I want light' to 'I want to blind.' Once the wizard's purpose inside changes, the order changes with it…
The old order collapses, then rebuilds into something new. So even using the same basic movement and sound, you don't get soft light anymore.
The only problem is the collapsed order messes with regular casting—anyone who learns the Blinding Light Curse can't reliably cast ordinary Lumos afterward. So I had to design a whole new ritual to stabilize it…
This is a spell reshaped by pure inner order—wisdom hasn't caught up yet."
Sean kept perfecting the notes as he spoke, the way most people would say "pass the salt."
"What do you mean by… reshaped? Order? Purpose? Collapse and rebuild?"
Harry looked like he'd been hit with a Confundus Charm.
"How does every word make sense on its own but turn into nonsense when you put them together?"
"I created a brand-new spell," Sean summed up.
"Oh, you could've just said that first," Harry said, relieved—then his eyes widened. "Wait—you created a new spell? Just now? On this bus?!"
"Mm."
For magic, Sean was always precise.
The Blinding Light Curse had proven his theory perfectly.
It used the same pronunciation and movement as Lumos, yet it had broken completely free of the thousand-year-old foundation spell. It wasn't an upgrade like red sparks versus green sparks.
It was something entirely new—from zero to one.
You could force it out with Lumos technique, but it would always feel awkward, because those weren't the movements that truly fit it.
And that proved the point.
Wizards look inward and build an unshakable inner Order. When they do, reality has no choice but to obey that Order.
Wisdom is just the wizard trying to sketch bones and flesh onto the magic they already carry inside.
