As the weeks leading up to Halloween passed, the castle began to change.
Not in structure, but in spirit.
Students noticed it first in the corridors at night — faint rattling sounds, like loose bones clacking together.
At first, everyone assumed it was just decorations being moved by the professors.
They were wrong.
The skeletons had returned.
And this time… they had personalities.
Whenever a Ravenclaw student walked past, skeletons lining the hallways would straighten instantly — jaws snapping shut, spines locking upright — before giving deep, respectful bows.
Some even saluted.
Ravenclaws walked through the halls like honored generals, trying (and failing) not to laugh.
Gryffindors received a different treatment.
Skeletons would wave enthusiastically at them and give thumbs-ups.
High-fives were attempted.
Bones occasionally fell off in the process.
Hufflepuffs, however, got the most chaotic interaction.
Skeletons would chase them down the halls — not aggressively, but eagerly — arms stretched forward, desperately trying to shake their hands and hug them.
"FRIEND! FRIEND!" one skeleton's enchanted jaw clattered as it ran.
Hufflepuffs screamed… then laughed when they realized they weren't in danger.
Slytherins received no such friendliness.
Whenever one passed, nearby skeletons would suddenly "malfunction."
Arms would jerk.
Legs would swing.
A few would lightly hit passing Slytherins on the head with detached bones before collapsing back into innocent piles of bones.
The hallways were filled daily with laughter, shouting, and Filch's distant yelling.
But the skeletons were only phase one.
Alexander Chen moved to phase two.
The pumpkins.
Dozens of enchanted pumpkins already lined the castle in preparation for Halloween — floating near ceilings, resting on pedestals, or sitting in window alcoves.
Alexander enhanced them.
Now they whispered.
Rumors.
Constantly.
As students passed, faint voices followed them:
"Snape smiling sends students to the Hospital Wing…"
"I heard he smiled once… three students fainted…"
"Bones liquefied…"
Naturally, this led to students attempting the impossible.
They tried to make Professor Snape smile.
Jokes.
Compliments.
One brave Hufflepuff told him his hair looked "particularly silky" that morning.
Fifty points were deducted.
Detention was issued.
The rumor only grew stronger.
No one ever succeeded — but many paid the price trying.
The pumpkins had other targets, too.
Whenever Mrs. Norris walked by, every nearby pumpkin would suddenly bark like a pack of dogs.
The cat would freeze, fur puffing up — before sprinting down the corridor in terror.
Filch, hearing the barking, would arrive seconds later to see only students laughing.
Which made him furious.
To make matters worse, pumpkins began making spitting noises whenever he passed.
Loud, echoing ptooey sounds followed him down hallways.
Filch would whirl around, red-faced, accusing random students.
"I KNOW IT WAS YOU!"
Detentions were handed out blindly.
The trio considered this one of their finest additions.
They didn't stop there.
More enchantments.
More whispers.
More layered rumors — so many that students couldn't tell the truth from pranks anymore.
Some pumpkins predicted exam questions.
Others claimed the suits of armor were forming unions.
One insisted the lake squid was applying for Head Boy.
But the most effective whisper targeted one particular professor.
Whenever Professor Quirrell passed, nearby pumpkins would murmur in chilling unison:
"Death Eater alert…"
"Death Eater alert…"
"Hide your wands…"
Quirrell would freeze.
Then hurry away, visibly shaken.
Students burst into laughter every time.
Even those who didn't like pranks couldn't deny it was funny watching him scurry off, turban bobbing nervously.
Reactions across the school were mixed.
Harry found it hilarious.
He laughed every time the pumpkins barked at Mrs. Norris or whispered at Quirrell.
Ron, inspired, begged his brothers to start a rumor campaign about Malfoy.
"I've got loads of ideas," he insisted.
The twins ruffled his hair.
"Next year, little Ronnie."
"Rumor crafting is an advanced discipline."
Ron accepted this with surprising pride.
Hermione, however, was not amused.
"You should all be studying," she scolded during one dinner.
"This is childish."
Alexander sipped his drink calmly. "Morale building."
"It's chaos."
"Structured chaos."
She groaned and went back to her books.
Cho, sitting beside Alexander, tried very hard not to laugh.
As October drew closer to its end, the atmosphere in the castle became electric.
Students anticipated what would happen next.
Because if the weeks before Halloween were this wild…
Halloween itself would be legendary.
One evening, after their usual training session, Alexander gathered the twins and Cho inside the Room of Requirement.
"I have an idea for Halloween Eve," he said.
The twins leaned forward instantly.
"How big?" Fred asked.
Alexander smiled.
"Bigger than last year."
George's grin turned feral.
Cho covered her mouth, already laughing.
The twins slammed their hands together.
"Then we plan properly."
"Scale, spectacle, psychological impact."
They began sketching ideas immediately — traps, illusions, castle-wide effects.
Bigger.
Louder.
Unforgettable.
As the plans grew more elaborate, Alexander leaned back, satisfied.
Halloween was approaching.
And the castle had no idea what was coming.
