Final Exams and Prophecy

One: The library's "subtle observation" pattern

Among the oak shelves of the Hogwarts Library, Cedric Diggory appeared for the third time in Hailey's usual corner. Dressed in neatly pressed Hufflepuff robes, a quill between his fingers, he bent over a copy of "Ancient Runes and Mechanical Gears," making notes in its pages. Light filtered through the stained glass edged his blond hair with gold. When Hailey caught sight of him from the corner of her eye, his chin was resting on his fist and his gaze was fixed on "An Illustrated Guide to Muggle Engineering" on the top shelf. He was completely absorbed in his reading, as though he had only happened to sit in that area.

For the past fortnight, Cedric had always appeared in the neighboring shelf section during afternoon study. He never initiated a conversation, quietly leafing through books related to "the fusion of Muggle technology and magic" instead. Occasionally, he looked up at the long table where Hailey drew her magical diagrams, studying her vibranium gear sketches with a Hufflepuff's characteristic focus and curiosity, as though examining a rare herb. Eileen nudged Hailey with her elbow and lowered her voice. "He studies your designs more closely than a Quidditch tactics board. Are you sure he isn't trying to sneak a lesson in cross-dimensional magic?"

Hailey aligned her vibranium ruler with the magical vortex lines on her parchment, deliberately letting a drop of ink fall on the area labeled "resonance frequency." "It's normal for a Hufflepuff Prefect to be academically curious. It's better than Slytherins watching our spice jars." Before she had finished speaking, a soft rustle of pages came from the shelves opposite. Cedric was sliding "Lever Principles in Wand Dynamics" onto a shelf. When his eyes briefly met Hailey's, he merely gave a polite nod, then turned toward the next row of shelves, the movement as natural as brushing dust off a page.

Two: An accidental academic encounter

Their first real conversation took place three evenings later. Hailey stood on tiptoe to reach "A Study of Magical Metal Ductility" on the top shelf. Her fingertips had just touched the spine when the entire row of books suddenly tilted because a screw in the old bookcase had come loose. She cried out and instinctively stepped half a pace back, only to see a hand with prominent knuckles catch the falling stack of books. Cedric had appeared behind her at some point, his badger-shaped badge glinting faintly in the dusk.

"Careful of the screws on the bookcase," he said, his voice as gentle as ever as he neatly restacked the books. "During Quidditch practice last year, I saw Filch secure this spot with magical tape." His gaze fell on the parchment in Hailey's hand, where a vibranium stress diagram drawn using a Muggle coordinate system was clearly visible. "Are you studying the relationship between metal and the conduction of magic? My grandfather once tried a similar structural analysis on the tail of a flying broomstick."

Hailey rolled the diagram into a tube, noticing a little silver powder on Cedric's cuff—a trace left by polishing metal. "I'm just trying to use a Muggle 'stress-strain curve' to explain vibranium's loss of magic." She pointed to an anomaly circled in red on the diagram. "The resonance peak here can't be explained by existing spell theory."

Cedric bent down to take a closer look, bringing with him the fresh scent of mint mingled with the smell of old pages. "It looks like 'turbulence' in magic at the microscopic structural level, much like the disrupted airflow when a broom breaks the sound barrier." He pulled a scrap of parchment from his pocket, a cross-section of a broom fin sketched on it in charcoal. "Look at this pressure distribution. Isn't it similar to the pattern of vibranium's magical fluctuations?"

Their discussion moved from the bookshelves to the long table. When Eileen came over clutching "The Complete Book of Spice Spells," she saw Cedric drawing airflow lines along the edge of Hailey's diagram with his quill. "If you added a phoenix feather at the gear junction, it might channel the turbulent magic, like the stabilizing charm on a broom's tail." His expression was focused and intent, and he was completely immersed in their academic discussion, without a single unnecessary gesture, as though he were merely offering ordinary guidance as a Prefect.

Three: The hidden defensive battle of the final exams

The written Defense Against the Dark Arts exam room smelled of parchment and ink. Hailey held her vibranium pen, writing about "adjustments to the magical circuit of the Disarming Charm" on her paper, when her pen suddenly paused. Professor Quirrell, wrapped in a purple cloak, had come to her desk on his rounds. His breathing came through the fabric of his turban, accompanied by an unusually strong smell of garlic. Out of the corner of her eye, she glimpsed the fabric at Quirrell's cuff trembling slightly. A faint smell of rust quietly spread with a fluctuation of magic, winding around her wrist like a spider's thread.

It was not an obvious spell attack, but a probe using low-frequency dark magic. The silver bracelet on Hailey's wrist gave a slight tremor, its metal gears making a click only she could detect. Without betraying a reaction, she turned the bronze ring on her middle finger. Her grandfather's Dust-Repelling Charm formed a cool barrier beneath her skin. At the same time, she brushed her Moon Phase Shield stud earring with a fingertip. The Red-Scaled Dragon scale in the pearl's inner layer activated instantly, silently refracting the ripple of dark magic away, like a pebble thrown at a lake's surface being caught by an invisible lotus leaf.

Quirrell's footsteps paused at her desk for two seconds. His gaze seemed to linger on her paper, or perhaps it had merely passed over it. "M-Miss Leicester," he said, stammering no differently than usual, "m-make sure your paper stays neat..." Then he turned toward the next row of desks. The air stirred by the hem of his robes brushed Hailey's paper, raising tiny ripples in the ink, which had not yet fully dried.

The entire process had taken no more than five seconds. Eileen, seated beside her, was bent over her paper, writing furiously and entirely unaware that anything was amiss. Hailey pretended to choke on the ink and coughed twice to conceal the slight trembling of her wrist, her gaze sweeping over Quirrell's retreating figure. His steps were steady, with no sign that he was deliberately targeting anyone. He simply patrolled like an ordinary exam invigilator, in keeping with his cautious, secretive nature. The other students were also occupied with their answers; no one noticed the silent clash taking place on the level of magic.

"Should the counter-charm for question three be Incendio?" Eileen whispered, leaning over after finishing her last stroke. A few spots of ink marked her butterfly hair clip. "I keep thinking Professor Quirrell looked at my paper strangely just now."

Hailey suppressed the turmoil in her heart and tapped the edge of her paper with her vibranium pen. "Maybe you wrote 'ginger-much' instead of 'Impedimenta,' and he was wondering whether to take points off." She deliberately brushed it aside in a light tone, but beneath the desk, her fingertips counted out the figures: the dark magic frequency was 180 hertz, a probing fluctuation. Hailey thought that Quirrell had not risked casting an obvious spell, choosing instead to use covert magical perception while invigilating the written exam. It was very much in keeping with the cautious logic of someone possessed by Voldemort: he had probed without exposing himself.

Four: The "dandelion fluff" plan for double-skin milk

After the exam, the Hogwarts Kitchens were filled with the mingled scents of caramel and milk. Hailey stared at the milk skin slowly setting in a copper pot, her brow furrowed like crumpled parchment. "There isn't enough moonstone powder left from the last experiment. What can we use to stabilize the magic fluctuations in the milk skin?" She poked the caster sugar in a porcelain bowl with the tip of her wand, and the grains glittered in the dusk.

Eileen turned a Muggle milk can upside down on the worktop, the milk residue on its bottom tracing a crooked gear pattern. "My dad says the Potions-grade dandelion fluff at the potion shop is all kept in Muggle tea tins, just like Earl Grey!" She suddenly lowered her voice, her panda hair clip turning an excited pale pink. "Once it's dried, dandelion fluff can be used as a magic buffer. It works much like a phoenix feather, just not as bright in color!"

Hogwarts House-elves floated silently past, carrying silver trays piled with gingerbread. Hailey glimpsed bits of dandelion on one House-elf's apron, and an idea struck her. "Are the dried dandelion flowers left over from Herbology last year still here? Professor Sprout said the fluff could be used to stabilize magic." She quickly opened the [magic refrigerator] and pulled out a battered Muggle tea tin. Sure enough, several tufts of snowy-white fluff lay inside. They were "Draught of Peace filler" from Eileen's father's potion shop, kept in a Muggle guitar-string tin, no different from a toffee tin.

"First we have to get rid of the 'volatile magic' in the fluff," Hailey said, placing it in a fine sieve and tapping the mesh with her wand. "Otherwise, the milk skin will bounce around like Peeves." Recalling the "magic filtration method" in her father's letter, she traced a spiral above the fluff with her vibranium ruler. Blue light gradually settled into a steady silvery white. Eileen took charge of mixing the beaten eggs and milk. After straining the mixture three times according to the Muggle recipe, she added two spoonfuls of pearl powder from the potion shop. "My mum says this stuff gives desserts a natural sheen. It works on the same principle as her face cream!"

Five: The cross-dimensional "fluff" fusion technique

When the dandelion fluff was sprinkled evenly over the milk skin, the entire copper pot gave a soft hum. Hailey gently lifted it with the tip of her wand, and the milk skin automatically curled into the shape of a gear. The fluff glimmered in the gaps, like lubricant embedded in the gear. "It worked!" Eileen's panda hair clip turned a shocked bright blue. "And it isn't bitter!"

At dinner, exclamations of amazement rose one after another from the Hufflepuff table, drawing looks from students in the other houses. The milk skin lay over the milky-white pudding like a cicada's wing. As it melted in the mouth, the fresh sweetness of dandelion fluff and the slight astringency of pearl powder created a wonderful layering of flavors. Cedric came by carrying a porcelain bowl, a little milk residue on his badger-shaped badge. "The texture of this milk skin is much like the shock-absorbing charm coating on my grandfather's broom. What magic did you use?"

Hailey scooped up a spoonful of pudding, looking at the gear pattern that had formed naturally on the milk skin. "I only added a little Muggle dandelion and pearl powder from the potion shop." She deliberately waved her spoon. "It's like putting a wool jumper on the magic." This was a combination of dandelion fluff's magical frequency and the method for making double-skin milk from her previous life.

Six: Late-night review and gear resonance

Late at night, Hailey took the hint from her father's conch and led Eileen to a corner of the Quidditch Pitch. The moonlit grass gleamed with silver frost, and beneath the stands they found a stone door concealed by ivy. "It's a magical lock reinforced with starburst iron gears," Hailey said, taking out a vibranium hairpin. "My dad said to turn it as though guiding magical resonance when opening it, rather than prying it open by force."

The moment the hairpin, infused with magic, entered the keyhole, the stone door gave a sound of meshing gears, but no magical light appeared. This was a typical concealed defense, forming a barrier solely through mechanical structures and magical resonance. Eileen held up her wand for light, revealing a room piled high with rusty gears. A blurred lightning pattern was engraved at the center of the largest, with tiny Runes along its edge: "1981, the year the balance of magic was upset."

Suddenly, the silver bracelet on Hailey's wrist began to vibrate violently. Every gear in the chamber resonated at once, yet produced no visible light. "It's silent resonance!" Even with the ring's effect, Hailey's bracelet still vibrated strongly. "Just like the Nonverbal Spell Dumbledore used at the opening feast!" They hurried out of the stone chamber. Behind them, the gears continued to turn slowly in the darkness, their movement barely perceptible to the naked eye, like the heartbeat of a prophecy under a Muffliato Charm.

Back in the dormitory, Hailey, a little dazed, picked up the double-skin milk pudding left over from the evening. With a "ding," the bowl suddenly made a faint sound. Hailey looked down and discovered that her magic had leaked into the bowl at some point without her knowing, causing a pattern of the gear chamber to appear on the double-skin milk. The lightning pattern on the milk skin overlapped with the starburst iron gear in her father's notebook at home, forming a complete Prophecy symbol. "It's a manifestation of the Prophecy!" Hailey held the porcelain bowl, her voice trembling with excitement.

Moonlight streamed through the stained glass, tracing clear gear paths at the heads of their beds. Hailey touched her hot bracelet and finally understood the deeper meaning of her father's evening conch message: the other Prophecy Dumbledore was pursuing shared an origin with the Leicester family's starburst iron resonance, and perhaps it was Hailey herself, who had crossed over. Everything happening now was only the tip of the iceberg of this grand Prophecy.

"Eileen," Hailey said, watching the pattern rotate on the milk skin, "what we cooked wasn't dessert. It's the key to the Prophecy."

An owl's hoot drifted past the window. In the claws of a silver-spotted owl was a letter with an unusual wax seal. Hailey knew that the next contest had quietly begun.
