Echo was a controlled burst of energy, his black robes fluttering behind him as he cut a sharp line through the crowded second-floor corridor. It was the Monday following the Easter weekend, and the castle was still buzzing with the aftermath of the Great Rabbit Hunt. Students scattered to avoid his trajectory, not out of fear, but from the simple need to maintain structural integrity—he moved like a minor magical storm. The silvery threads of residual chaos from the morning's activities were still faintly visible in his hair, shimmering like an aurora against the base color of matte black, a clear sign that his energy was soaring. He slowed abruptly as he approached a quiet window nook near the Charms classroom. Lily Evans was perched on the sill, entirely absorbed in a massive, leather-bound volume, a lock of her fiery red hair falling over her cheek as she read. She was oblivious to the hallway's bustle, a perfect island of studious calm.
"Morning, Lily-flower," Echo greeted, his voice a low, cheerful rumble. The silver threads in his hair intensified, laced with a flicker of genuine affection, a color blend that looked oddly cheerful.
Lily gave a slight hum in response, not lifting her head. "Morning, Echo." She finally reached the end of a paragraph, marked her place with a fingernail, and pulled her face from the book, giving him a quick, warm smile. "Have a good weekend, you enormous pink menace?"
"The best," Echo replied, leaning against the cold stone wall, enjoying the placid black in her gaze. "I'm thinking of making the bunny suit my permanent formal wear."
Lily's smile faded, and her brow furrowed slightly. She blinked, her head tilting, her green eyes fixed not on his face, but on the area just above it. Her expression shifted from amused to inquisitive, then quickly to a mix of confusion and mild alarm.
"Echo," she said, her voice dropping to a sharp, cautionary tone. "Stop."
Echo, who had already begun to move, instantly froze. His silver threads snapped back into the matte green of deep confusion. "What? Did I forget a lecture? Did Snape put a hex on my shoes?"
"No. Just… stop right there," Lily commanded. She carefully set her book aside and pointed a precise finger at his head. "What is that?"
Echo blinked, genuinely confused. "What is what? My hair?"
"Yes, your hair!" she exclaimed, her voice rising in pitch. "Why is it so... so frizzy and wild? It looks like a massive, unruly cloud. It's sticking out everywhere! It looks like a bird's nest."
Echo reached up and grabbed a thick lock of the dark hair, pulling it down past his shoulder. The length was considerable, a flowing curtain that usually rested in sleek, perfect waves. He frowned, running his fingers through the texture. It was indeed far less compliant than usual, possessing a strange, voluminous fluff.
"Oh," he said simply, shrugging. "I must have forgotten to do it this morning."
Lily slid off the windowsill, her full attention now focused on his hair. "Wait. Forgotten? What do you mean, 'do it'?" She gave him an intensely scrutinizing look. "How exactly do you do your hair, Echo?"
His silver threads reappeared, now shot through with the cold, uneasy blue of suspicion. "Why the sudden interest, Lily? Are you going to recommend a high-end Muggle hair salon?"
Lily sighed, shaking her head. "I love you, Echo, I truly do. But you are a child of extremes. I know you don't know much about self-care or moderation. This is one of those things, isn't it?"
Echo bristled, his black hair instantly surging with an angry, defensive red. "I know things! I know how to care for myself! I am a self-renowned Beast Wizard who knows how to remove a magical collar from a Zou Wu. I can handle basic human needs!"
"Oh, really?" Lily retorted, crossing her arms. "You once ate several pounds of expired chocolate that a House-elf left out, got a massive stomachache, and nearly died of food poisoning. And then you got five cavities because you didn't know you had to brush your teeth every day."
The red in his hair instantly dissolved into a sheepish, deep violet. "That was one time! And I thought the House-elves were just leaving me a gift basket!"
Lily ignored his protest, leaning closer to inspect the ends of his long, flowing hair. "And just now, I'm realizing that you have terrible split ends. And they're big. You need to trim them."
Echo clutched his hair protectively. "No! I like my long hair!"
"It's only a trim, you great lump," Lily said, her voice softening slightly. "But seriously, how do you manage that perfect black every day, when you're clearly incapable of basic grooming?"
Echo sighed, the defensive anger gone, replaced by a strange mix of resignation and a flicker of playful mischief. "Fine. You want to know my secret? You want to know how the most hated thing in Hogwarts does his hair?" He pulled the thick mass of hair back from his face. "I'll show you."
He started walking rapidly down the corridor, pulling Lily along by the sleeve. He stopped them abruptly in a forgotten stretch of the third floor where an ornate, marble fountain of a roaring lion stood, pouring a steady stream of water into a large basin.
Lily looked from the pristine marble fountain to the massive, unruly black cloud of his hair. "Echo, why are we at a public fountain?"
"It's the closest, clearest water source," Echo said, his voice dropping to a stage whisper. He turned to the fountain, dramatically pushing his sleeves up his arms. "Now watch and learn, Lily-flower. But be warned: you're about to learn some real magic!"
Lily watched, her heart thumping with a mixture of terror and curiosity, truly afraid of what she was about to witness. Echo bent over the marble basin, ducking his head beneath the roaring lion's mouth. He let the cool, clear stream of water drench his thick, unruly mass of black hair. He worked the water in with large, systematic hands, wetting the strands from the roots at his scalp all the way down to the frizzled, dry tips.
Lily watched the surprisingly methodical process, nodding along. "Okay, soaking it is step one. Normal enough."
Echo pulled his head back, droplets spraying across the marble. "See? I told you I knew how to do this. I make sure it's all nice and wet. And when I'm sure my hair is completely soaked through, I pull it out." He flipped the heavy, dripping curtain of his black hair back over his shoulder.
Lily blinked at the water-logged sight. "And then?"
Echo beamed, spreading his arms wide. "Then comes the drying!"
Lily's jaw dropped. "What? No shampoo? No conditioner?"
Echo frowned, his brow furrowed in genuine confusion. "What is that?"
"I'll explain that afterwards," Lily said, shaking her head in frustrated resignation. "Just keep going."
Echo shrugged off her confusion. He closed his eyes and poured his unique, dark beast magic out into the castle. He reached for two very specific consciousnesses, giving them a sharp, demanding mental tug. "Shimmer! Pip! Hit it!"
With a soft, almost imperceptible pop and a flash of shimmering silver, the Demiguise, Shimmer, materialized instantly on the edge of the fountain. At the same moment, with a sharp thwack of air, Pip—Echo's personal House-elf, dressed in his miniature, perfectly tailored green outfit—appeared on his shoulder. Shimmer, never one to miss a moment of theatrical flair, took a running start, jumped onto the lion's head, and with a flourish, pulled a him-sized electric guitar from what seemed to be a pocket in the air. The Demiguise plugged the instrument into the stone, which instantly roared to life as an amplifier. Shimmer then hit a deafening, hard-rock power chord.
KERRR-RANG!
Echo immediately began to thrash his head, shaking his long, water-soaked hair back and forth in time with the driving beat. Water flew everywhere, scattering in a wide, shimmering arc. Lily let out a startled yelp and shielded herself with her arms, stepping back rapidly to avoid the spray.
Pip, the House-elf, cupped his hands around his mouth and yelled over the din. "Miss Lily! Best step back a bit! This part gets messy!"
As Echo continued his vigorous, head-banging motion, something else began to scatter from his hair, falling onto the marble floor like a dusting of tiny, dark pepper flakes.
"Oh, God!" Lily shrieked, jumping back a final, massive step. "There are… There are little black things all over the floor! They're moving! Are those… head lice?"
Pip gave a theatrical shudder. "Yes, Miss! But not for long!"
Shimmer cut the heavy-metal power chord instantly. The music vanished, replaced by a sudden, profound silence. Pip, the House-elf, hopped down onto the fountain's edge, pulled a tiny fiddle from his own clothes, and began to play a fast, cheerful Irish jig. The music was impossibly loud for the instrument's size.
Echo, without missing a beat, instantly transitioned his head-banging into a furious, high-stepping dance. He stomped, spun, and jigged around the basin, his black boots methodically crushing every single moving speck on the marble floor. The dance was energetic, precise, and utterly insane. When the last of the tiny black specks had been neutralized and the floor was clean, Pip finished his tune with a triumphant flourish. Echo stopped dancing, panting slightly, his hair now damp but no longer dripping.
"And that's the drying part," Echo announced, wiping his forehead with the back of his hand.
Lily, still standing several feet back, stared at the two magical creatures and the bizarre performance. "That… that was just to kill the lice? And dry your hair?"
"Yup!" Echo said cheerfully. "One more step."
Shimmer, the Demiguise, immediately vaulted from the lion's head. The creature landed softly on Echo's head, its silver fur blending seamlessly with the black of his hair. Shimmer's long, prehensile tail uncoiled and, using the sensitive tip like a comb, the creature began methodically combing out Echo's long, damp hair, smoothing it into the sleek, flat, compliant style it usually had. The Demiguise worked quickly, taming frizz and static until the hair lay perfectly straight.
Echo finished the process by pushing the rest of the hair from his face, letting it fall in a perfect, thick curtain down his back. He gave a smug, self-satisfied smile. "And that's exactly how I do it every day… every other day, anyway."
Lily sighed, a long, mournful sound of profound disappointment. "Echo, that's gross. You do realize that Shimmer is grooming your hair with the same mouth he eats and licks himself with, right?"
"So?" Echo countered, genuinely confused. "I do the same thing."
Lily threw her hands up in exasperation. "I'm not even going to unpack that. Okay, forget next class. I'm going to take you to Gryffindor Tower, cut your split ends, and show you how to properly wash your hair with shampoo, conditioner, how to dry your hair, and use a brush, because I can already tell you have no idea what I'm talking about."
Echo shook his head, a look of profound, honest ignorance on his face.
Lily looked over at the House-elf, who was polishing his tiny fiddle. "Pip, I would like you to come with us and watch. Just in case Echo forgets, or decides not to heed my words."
Pip snapped to attention, giving a sharp salute and a thumbs-up. "Pip will watch, Miss Lily! Pip will make sure Mr. Echo is clean!"
Echo bristled, his hair flashing red. "Hey! When have I ever done that?"
Lily shot him a look that recalled his three-day, sugar-dusted disappearance.
Echo instantly sucked air between his teeth. "Oh. Yeah."
Lily grabbed Echo by the massive, velvety sleeve of his robes and started pulling him down the corridor. "Come on. Let's teach you how to groom yourself properly, and not from a monkey."
Echo trailed behind her, the Demiguise still perched contentedly on his head. "But aren't we technically monkeys, Lily?"
Lily simply let out a loud, shuddering sigh.
