Omake 1 : "It's Just Basic Magic Theory, Bro"
(Non-canon crack chapter – the Knight Bus will never recover)
The Knight Bus was doing its usual impression of a drunk hippogriff on roller skates when Sean looked up from his notebook like he'd just remembered he left the oven on.
"Finished," he said calmly. "Blinding Light Curse. First successful reshape."
Stan, who had been mid-sentence praising Green's Notes: Standard Spellcasting for the seventeenth time, froze so hard his spots went pale.
"You… you just made a new spell? On my bus? While we're doing 300 km/h through a hedge in Wales?"
Sean shrugged. "It was quiet. Good environment for subtracting inner order."
Harry's brain blue-screened. "Subtracting… inner… what now?"
Sean turned the notebook around helpfully. The diagram showed a wizard holding a wand that looked like it had swallowed the sun.
"See? Lumos, but instead of 'please give me light,' the inner order is now 'please make everyone regret their life choices.' Same wrist flick, same syllable, completely different reality. The old order collapsed, I rebuilt it, and now reality has to obey the new one. Wisdom hasn't caught up yet, so the ritual's still a bit janky, but—"
Harry raised a hand like he was in class. "Mate. English. I just wanted to know if it's a really bright flashlight."
"It's a really bright flashlight that weaponizes the concept of light," Sean said, as if that cleared everything up. "Think of it as Lumos after it went to therapy and decided to become a war criminal."
Stan made a noise like a teakettle being murdered. He dropped to his knees right there in the aisle (the bus immediately swerved because Ern was too busy staring).
"Mr. Green… sir… god-emperor of spell standardization… can I… can I have your autograph on my forehead? No, wait, on my soul? I'll name my firstborn Blinding Light Curse Shunpike, I swear on Merlin's left sock—"
From the upper deck came a muffled scream. Madam Marsh had apparently woken up and seen the diagram.
Ern gripped the wheel tighter. "Right, Ern?" he muttered to himself. "Totally normal Tuesday. Just a second-year inventing forbidden magic on the night bus. Right, Ern."
Harry clutched his pillowcase of books like a life raft. "Sean. You rewrote a foundational spell because you were bored on public transport. I'm still pretending to be Neville and you're out here speed-running godhood. My life is a fever dream."
Sean tilted his head, genuinely confused. "It's not that impressive. I just removed the parts that were holding it back. Like subtracting to emptiness, remember? Order eternal."
Harry stared at him for five full seconds.
"…You know what? I'm going back to being Neville. Neville doesn't have to deal with this. Neville has plants and a gran who only hits him with handbags."
At that exact moment, the bus slammed through another hedge. Something large and purple floated past the window outside, screaming.
"PUT ME DOWN YOU LITTLE BASTARD I'M STILL INFLATED!"
Marge. Still. Floating. Somehow attached to the roof rack like a very angry parade balloon.
Stan didn't even notice. He was too busy trying to kiss Sean's shoe.
Harry buried his face in his hands. "I left the Dursleys for this?"
Sean patted his shoulder gently. "Want me to blind the bus so we can all take a nap?"
Harry's scream was heard three counties away.
Ern just sighed. "Right, Ern. Another normal night on the Knight Bus."
Omake: "Basic Magic Theory, Bro – The Knight Bus Incident That Broke Reality"
(100% non-canon, zero brain cells were harmed… except Stan's)
The Knight Bus was currently pretending to be a pinball machine with anger issues, ricocheting between dimensions at 400 km/h while Ern muttered "Right, Ern" like a broken record.
Sean looked up from his notebook with the calm expression of someone who'd just finished a grocery list.
"Done," he announced. "Blinding Light Curse. First successful inner-order reshape. Should be good."
Stan, who had been mid-rant about how Green's Notes changed his life, froze so hard his acne formed a perfect constellation of terror.
"You… you just invented a brand-new spell? On my bus? While we're playing demolition derby with Welsh hedges?!"
Sean shrugged like he'd just invented sliced bread. "It was quiet. Good vibes for subtracting to emptiness."
Harry's soul left his body. "Subtracting… to… emptiness? Mate, I asked if it was a really bright flashlight!"
"It is a really bright flashlight," Sean said patiently, turning the notebook around. The diagram showed a wizard whose wand was basically a portable nuclear explosion. "But now the inner order is 'make everyone regret existing.' Same flick, same syllable, reality just… obeys the new management. Old Lumos order collapsed, I rebuilt it. Wisdom's still lagging, so the ritual's a bit janky, but—"
Harry raised both hands like he was surrendering to the IRS. "ENGLISH, SEAN. I just wanted to know if I can use it to read in bed!"
Sean blinked. "You could read the surface of the sun with this. Or blind a dragon. Or accidentally commit war crimes on a Tuesday. Whatever you're into."
From the upper deck came a blood-curdling scream. Madam Marsh had woken up, seen the diagram, and immediately tried to Apparate through the ceiling. She only succeeded in embedding her head in the roof like a very angry weathervane.
Ern didn't even flinch. "Right, Ern. Tuesday."
Stan dropped to his knees in the aisle so hard the bus swerved and took out three phone boxes. "MR. GREEN, SIR, LIGHT OF MY LIFE, STANDARDIZER OF SPELLS—can I have your autograph on my forehead? No, wait, tattoo it on my soul! I'll name my firstborn 'Blinding Light Curse Shunpike the Second' and raise him to worship the footnote on page 47!"
Harry wheezed. "I left the Dursleys for this? I could be getting shouted at by Vernon right now. That was safer."
At that exact moment, something large and purple slammed against the window outside.
"PUT ME DOWN YOU RUDDY LITTLE BASTARD I'M STILL INFLATED AND I'VE GOT A TEA PARTY AT FOUR!"
Aunt Marge. Still ballooned to the size of a parade float. Somehow strapped to the roof rack like the world's angriest lawn ornament, arms and legs flailing as she screamed past at 400 km/h.
Stan didn't notice. He was too busy trying to French-kiss Sean's shoe. "Teach me the ways of inner order, senpai! I'll subtract my dignity! I'll empty my bank account! I'll—"
The bus hit a pothole the size of Belgium. Stan flew upward, collided with the ceiling, and came down wearing Madam Marsh's nightcap like a crown.
Harry pointed at Sean with a trembling finger. "You created a forbidden spell on public transport because you were bored. I'm still pretending to be Neville and you're out here speed-running Dark Lord speedrun strats. My life is a fever dream written by Luna Lovegood on acid."
Sean tilted his head, genuinely confused. "It's not forbidden. I just removed the parts that were holding it back. Like… pruning a bonsai. Except the bonsai can now commit light-based terrorism."
Harry screamed into his pillowcase. "I WANT MY CUPBOARD BACK!"
Ern finally spoke without the "Right, Ern." He sounded personally offended. "Lads, I've driven this bus for forty years. I've seen drunk trolls, time-traveling house-elves, and once a herd of invisible thestrals playing chicken. But this? This is a new low. I'm writing a strongly worded letter to the Ministry. Or crying. Probably both."
The bus slammed through another hedge. Marge's screams reached new octaves previously only achievable by mandrakes on helium.
Stan, now wearing the nightcap backwards, crawled toward Sean on his knees. "Just one spell, Mr. Green! Teach me how to make my acne subtract to emptiness! I'll pay in exposure! I'll pay in tears!"
Sean, still perfectly calm, raised one finger. A single, innocent spark of Blinding Light appeared at the tip.
The entire bus interior went supernova white.
When the light faded, Stan was curled in the fetal position, whispering "inner order… inner order…" while his spots had rearranged themselves into the words "I LOVE GREEN."
Harry's glasses were completely fogged. "I can't see. I can't see my future. I can't see my past. I regret everything."
Sean gently patted his shoulder. "Want me to fix your vision? I could reshape the light-order in your eyes real quick—"
"NO!" Harry and Ern shouted in perfect unison.
From the roof came one final, distant wail: "MY TEA PARTY IS RUINED AND I BLAME MAGIC!"
The Knight Bus screeched to a halt outside the Leaky Cauldron. The door opened.
Sean stepped off first, notebook tucked under his arm like nothing had happened.
Harry followed, dragging his trunk, looking like he'd aged ten years in ten minutes.
Stan poked his head out, still blind, nightcap askew. "Mr. Green! One last question! Can I… can I call my future children after your footnotes?"
Sean considered it. "Only if you promise to raise them on controlled experiments and good sleep hygiene."
Harry walked straight into a lamppost.
Ern just sighed, lit a cigarette with a trembling hand, and whispered to the empty bus:
"Right, Ern. I'm retiring. Tomorrow. Maybe yesterday. Time travel's real, right?"
