Christmas Afterglow and Suspicions in Diagon Alley

Hailey woke to the sweet aroma of roasted chestnuts.

Sunlight streamed through the stained glass, casting colorful patches across her four-poster bed. Curled up beneath her down quilt, she tapped her fingertips absently against the sheets, humming "ALL I WANT FOR CHRISTMAS IS YOU," which she had heard in a shopping mall before transmigrating. The off-key tune mingled with the crackle of a wizarding fireplace, like Muggle toffee stirred into Christmas pudding. Half-unwrapped presents were piled on her bedside table, and a gingerbread-man-shaped gift box leaned to one side, its icing smile accidentally scorched into a little hollow by a wand.

"The tune you're humming sounds like bubbling Butterbeer, miss!" Nini's shrill voice came through a crack in the wardrobe. The House-elf held a silver tray bearing hot cocoa that bubbled with the scent of cinnamon. "Mrs. Leicester said we're having turnip cake this morning..."

Before Nini could finish, Hailey jolted upright, her hair brushing the Star Hub Necklace hanging by her bed. The combination of emerald-green magic and Vibranium gears gave a sudden soft click, and the gear bracelet on her wrist resonated in response, like two owls being tickled. She hurriedly felt for the bronze ring on her middle finger. The Dust-Repelling Charm ring her grandfather had left her glowed with a cool silver light, pressing the restless ripples of magic into gentle waves that vanished into the air in an instant.

"Let's see what happened this time," she muttered, throwing back the quilt and stepping barefoot onto the carpet. Her toes touched a long gift box. The dark purple velvet lid bore the Leicester family crest, and the moment she opened it, a silvery-blue magical glow spilled through the gap, making her squint.

"Been waiting for you!" Mr. Leicester called from the doorway, swinging his gold pocket watch, its chain casting gear-shaped patterns of light and shadow in the morning sun. She pointed at the gift box, the present her parents had promised to let her guess at the night before. "Your mum used a Thunderbird's tail feather to 'quench the shine' on the earrings in the attic last night. She nearly welded the cauldron to the workbench."

Mrs. Leicester followed behind him, her moon-phase pendant replaced by matching pearl earrings, her eyes curved with a smile. "Want to try them? These Moon Phase Shields look like Muggle saltwater pearls, but the layers contain fragments of scales from a 1926 Guizhou Red-Scaled Dragon and Thunderbird Feathers-" Before she finished, Hailey had put on the necklace and slipped in the earrings. Translucent ripples suddenly spread across her earlobes, like a magical lake disturbed by a thrown stone. "Back then, when I was accidentally hit by a Transfiguration Spell, it was something similar that blocked the shock wave of out-of-control magic for me."

The butterfly hair clip beside them was even more eye-catching. Its body was shaped like Eileen's butterfly clip, but its wings shimmered with the iridescent gleam of scales. Hailey touched it lightly with the tip of her wand, and the scales immediately refracted tiny specks of light, as though sunlight had been kneaded into a magical prism. "The Illusory Colour Dragon scales have a Spell-Deflection Charm on them," Mr. Leicester said, pushing up his glasses. "They were the prized treasure of your Aunt Eileen's Potions shop. I traded three crates of Mandrake for them. Remember not to show them off in front of Snape, though, or he'll think you're wearing peacock feathers."

Hailey clipped the butterfly into her hair, and its wings trembled gently. The resonance between Vibranium gears and dragon scales reminded her of the neon lights on Chinatown's ceremonial archway. Necklace, bracelet, ring, earrings, hair clip—she was a walking magical arsenal now, but wrapped in her Hufflepuff wool scarf, she looked just like a magical nut coated in icing.

"Dad, can this clip refract jinxes?" She tilted her head at the mirror, sparks from the fireplace reflected in the butterfly's wings. "Last time Eileen sprinkled Sichuan pepper into the cauldron, that's how the Blasting Curse flew out."

"The principle is the same as when you throw a snowball in a parabola." Mr. Leicester tapped her on the head. "It breaks the force of impact down into circular motion. But remember, this thing can only block three times. After that, you have to 'feed' it Vibranium scraps. You can think of it as changing the batteries."

The Rosier family's sitting room smelled of nutmeg and old parchment. When Hailey arrived, she saw Eileen sprawled across the carved table, flecks of ground nutmeg in her blond hair, her nose almost touching the Guide to Pairing Spices and Spells. Dried turmeric slices and Muggle measuring spoons were tucked between its pages.

"Quick, have a taste!" Hailey set a tin covered in "magical Preservation Charms" on the table. The moment she opened it, the savory aroma of cured meat in the turnip cake burst out, mingled with Vibranium's distinctive sweetness. "I added Madagascar vanilla pods from your shop, and some Vibranium powder my dad had secretly stashed away. It's a Christmas return gift!"

Mrs. Ronil came over carrying a silver pot and tapped the tin with the tip of her wand. The Vibranium preservation layer immediately glimmered with a fine blue light. "Oh, Merlin! This craftsmanship is even finer than our Potions shop's Box of Eternity! The Leicester family's little rascal used Muggle 'calculus' to calculate the magical fluctuations and applied them again, didn't she?"

Hailey stuck out her tongue, not wanting to explain too much, and pulled out a small velvet pouch, pressing it into Eileen's hand. "Close your eyes!"

When the panda-shaped hair clip landed in Eileen's palm, its black-and-white fur suddenly glimmered, and the magical gemstones in its eyes began changing from pale blue to pink. "I took apart a Muggle panda doll, shrank it, and stitched in a Mood Colour Change Charm." Hailey pointed at the clip's ears. "I sewed your favorite turmeric powder into the ears. Give it a shake-" She took Eileen's hand and shook it, and sure enough, a whiff of turmeric mixed with a milky scent drifted out. "Doesn't it smell like the Butterbeer ginger sweets you sneak me?"

Eileen squealed and clipped it into her hair. The panda's eyes turned bright pink in a flash, even more flamboyant than Professor Flitwick's pointed hat. "This is cooler than an Ollivander wand! Next time Professor Quirrell glares at me, I'll shake the clip so he can smell the turmeric. It smells better than the garlic on him, anyway!" She suddenly lowered her voice and poked Hailey's arm with the shaft of her quill. "Last night I overheard Dad saying Uncle Leicester bought Starburst Iron in Diagon Alley for a high price. Is he making you a new toy?"

Hailey was just about to speak when she saw Mrs. Ronil muttering over the turnip cake in the tin, drawing what turned out to be Muggle chemical element symbols with the tip of her wand. She suddenly remembered her father mentioning "industrial espionage" and hurriedly pulled Eileen toward the garden. Behind them came Mrs. Ronil's muttering: "This Vibranium molecular arrangement... it looks just like the catalyst structure for our Invigoration Charm..." Hailey thought to herself, Aha, a little rivalry between the grown-ups.

Before returning to school, Hailey slipped into Diagon Alley with her book list tucked away. The Lumos at the Ollivander Wand Shop was especially dazzling after the snow, but she stared at the old wands displayed in the window. The wands' cores and the grain of their wood looked strikingly like the twisted words "sacrifice" on the torn page of the Prophecy book that often appeared in her dreams.

"Harry should be starting school next year." She crouched outside Eeylops Owl Emporium, watching silver-spotted owls fly back and forth with letters in their beaks, and suddenly remembered the boy at 4 Privet Drive who was always feeding sparrows by the bins. According to the timeline, around this time next year, Hogwarts letters would be pelting the Dursley family like cannonballs, but Aunt Petunia would definitely burn them all.

But the more she thought about it, the stranger Dumbledore seemed. As the greatest wizard, he could easily have entrusted Harry to the Ministry of Magic's Muggle liaison officer instead of the Dursley family, whom he knew to be hostile. Hailey remembered Dumbledore's "belated realization" of Harry's childhood suffering in the original story. Hogwarts' Sneakoscope magic could monitor students' conditions, yet he insisted on waiting until Harry started school to be "surprised" by how thin and weak he was. It was just like a piece on her father's chessboard deliberately feigning weakness.

"By Muggle 'cost-benefit' calculations, those odds are far too high." She kicked aside the snow at her feet, remembering her father's analysis the night before. Spinning his gold pocket watch, Mr. Leicester had said, "Dumbledore is betting on Harry's resilience, like betting on an unlikely stock to soar, but he's using a child's childhood as his stake."

Her mother, meanwhile, had gently stroked her hair, her moon-phase earrings glowing softly in the lamplight. "Perhaps he's counted on Petunia's complicated feelings for Lily, deep in her heart-just like you always hide Eileen's turmeric powder at the very bottom of the sugar jar."

That afternoon, the Leicester family's study was wrapped in three layers of Silencing Charms. Behind a hidden door in the bookcase, Mr. Leicester was adjusting a Muggle oscilloscope, magical waveforms pulsing across its screen amid wizarding star charts.

"Dumbledore's thinking is still stuck in the reverse logic of Pure-blood supremacy." Mr. Leicester tapped the screen with his wand, and the waveforms instantly turned gear-shaped. "He thinks wizarding blood is enough to withstand the damage of a Muggle environment, but he's forgotten that Harry is first and foremost a child who needs a hug."

Hailey sat on the carpet with her knees hugged to her chest, her fingertips rubbing the spiral pattern on her bronze ring. "But he's the 'chosen one' in the Prophecy. What if..."

"The Leicester family's protective charms have never been chains." Mrs. Leicester crouched down and pressed a cup of hot cocoa into her hands. "They're oil for the gears. Your dad has already made life difficult for the Dursley family with Muggle 'community complaints,' and Eileen's mum has stuffed anonymous 'children's nutrition recipes' into the letterbox on Privet Drive. Muggle gossip works better than intervening through the rules of the magical world."

Mr. Leicester switched off the oscilloscope, his gold pocket watch ticking softly and steadily against his chest. "Remember, stay away from the Prophecy's core gears. We'll be an inconspicuous life ring-like this." He pulled out a metal ball the size of a walnut, its surface engraved with Muggle calculus formulas and wizarding defensive spells. "A Vibranium Force Field Generator. It uses the principle of a parabola to break down the force of a spell's impact. Your mum stayed up late making it into an ornament and sewed it into the tongue of your shoe."

Holding the metal ball, Hailey suddenly remembered how the old woman in Chinatown had taught her to knead turnip cake: be patient, be even, and find the pattern in apparent disorder. The gears of the Prophecy might be destined to turn, but she could add a little "oil" to every meshing point and spare Harry some wear and tear.

On the night before departure, Hailey practiced the Vibranium Force Field Charm in the attic laboratory. The tip of her wand traced not a traditional magic circle but a spiral derived from Muggle geometric formulas. Vibranium powder floated with her magic, forming a translucent, gear-shaped shield in her palm.

"Imagine the force of the spell as a snowball being thrown at you." Mr. Leicester tossed a rubber duck with his wand. "Your shield needs to be like a ski, breaking the impact down into a forward gliding force."

Hailey took a deep breath. Just as the shield formed, the rubber duck hit it with a bang, then floated along an arc onto the sofa without even wrinkling a cushion. Nini watched open-mouthed from the side, the woolen sock in Nini's hands dropping to the floor. "Your spell is like a magic trick, miss! It's even more amazing than when you took that gold pocket watch apart and made it into a clockwork bird!" Hailey glanced speechlessly at Nini, who actually remembered things from her childhood so clearly.

When the whistle of the Hogwarts Express pierced the morning mist, Hailey and Eileen stood on Platform Nine and Three-Quarters. Eileen's panda hair clip flickered as she bounced, its eyes turning bright gold with excitement. Mr. and Mrs. Leicester stood nearby, her mother's moon-phase earrings and her father's gold pocket watch forming a subtle magical resonance.

"Remember to 'feed' the force field generator in your scarf some Vibranium scraps every week." Mr. Leicester ruffled Hailey's hair. "Just like charging a Muggle."

"And," Mrs. Leicester said, straightening her scarf and pressing a fingertip gently against the spot where the Vibranium Force Field Generator lay, "if you come across an equation you can't solve, think about how turnip cake is made. Take it slowly; you can't rush it."

As the train started, Hailey touched the Star Hub Necklace around her neck. The necklace wrapped around her wand, resonating steadily with the magical items she wore, like the precisely operating instruments in her father's laboratory. The Muggle world outside the window gradually fell away, and she thought of Chinatown's neon lights, the steam from turnip cake, and the new spell she had recently forged with Vibranium powder and mathematics.

This term, she was no longer the transmigrated girl whose hands trembled with fear at the Prophecy.

She was Hailey Leicester, a young Hufflepuff witch armed with cross-dimensional wisdom and shields from magical items. Hogwarts castle was like a vast magical cauldron, and she was ready to use Muggle logic and a wizard's magic to quietly sprinkle a handful of cross-dimensional seasoning into the thick soup of the Prophecy-seasoning that could make everything warmer.

Eileen suddenly pointed out the window and shrieked, "Look! Those owls are carrying gingerbread men!"

Hailey smiled, her fingertips brushing the Vibranium Force Field Generator in her scarf. In the distance, the castle spires gleamed silver after the snow, while in her palm, emerald-green magic and the faint light from her Vibranium accessories intertwined into a net, looking just like the warmest layer of oil floating on the surface of her mother's ginger tea.
