Echo didn't go to the Slytherin common room. He didn't seek out the quiet comfort of the Room of Requirement, nor the vast, desolate peace of the Black Lake. He went to the highest point in the castle, the Astronomy Tower, and sat on the cold stone floor, hugging his knees to his chest. The exhaustion was absolute, a bone-deep ache that rendered his magic inert. The raw, miserable gray-blue of his hair was a perfect reflection of his hollow state. He was alone, and the silence was profound, broken only by the cold rush of the night wind.
He stared out at the quiet castle grounds, now utterly peaceful, as if the terrifying storm of the Nebuina and the Veela's betrayal had never occurred. He had traded one loss for another: the safety of a species for the precarious safety of the peace. The silence was a lie, and the loneliness was deserved.
A few minutes later, the heavy wooden door to the tower staircase creaked open, and the sound of hurried, heavy footsteps echoed on the stone stairs. Echo didn't move. He didn't need to look up to know who it was. The sheer kinetic energy of their arrival was unmistakable.
"Echo!" James's voice was sharp with relief, followed by a panting exhale. "We've been looking for you everywhere! McGonagall sent us out after the whole… whatever that was."
The four Marauders—James, Sirius, Remus, and Peter—poured into the circular space. They spotted Echo huddled on the floor and, after exchanging a quick, worried glance, they didn't try to drag him to his feet or bombard him with questions. Instead, they simply collapsed onto the stone floor around him, forming a messy, comforting circle.
The silence returned, but it was no longer empty. It was filled with the collective, easy breathing of companionship. Sirius, restless even when sitting, finally nudged Echo gently with his elbow.
"Alright, mate, what are we doing?" Sirius asked, his voice low and concerned. "You've got that look on your face like you just invented a new curse but forgot what it was for. What's holding your attention?"
Echo didn't answer right away. He slowly lifted his hand, his movement lethargic, and pointed across the circular room. "I'm watching monkey flips," Echo whispered, his voice flat.
The four Marauders followed his gaze. They saw Shimmer, the small, highly energetic, and entirely chaotic monkey-like creature, standing atop one of the massive, brass-ringed telescopes. Shimmer was about four feet off the ground, and he was currently facing away from them, his back perfectly straight. He looked as if he were contemplating the vast, uncaring cosmos.
As they watched, Shimmer suddenly flung himself backward. He executed a sloppy, mid-air backflip, rotating once before landing feet-first on the cold stone floor with a slight thump. He didn't stick the landing perfectly; his back legs gave out, and he wobbled for a moment before righting himself.
Remus tilted his head, confusion etched onto his face. "What is he doing, Echo? Why is he flipping?"
Echo shrugged, a small, weary movement. "Doesn't matter. It makes me feel better."
The boys watched. Shimmer clambered back up the telescope, spun around to face the endless dark, and then, with a dramatic flourish of his tiny paws, he executed another mid-air backflip. This one was better, sticking the landing momentarily before he tripped over his own tail.
James, after a moment of stunned silence, suddenly threw his head back and let out a short, incredulous burst of laughter. "What the…?" he stammered, shaking his head. He looked down at Echo, his expression shifting from amusement to genuine perplexity. "You know what? I'm not even mad, sad, or upset about anything, and I am somehow feeling better. That was just… utterly pointless."
"Yeah," Echo agreed, the ghost of a smile touching his lips. "Monkey flip works like magic. Why are you four looking for me anyway? I thought you'd be doing literally anything else but share in my wallowing."
Peter, who had been watching Shimmer with rapt fascination, finally managed to tear his eyes away. "You know how the final event of the Triwizard Tournament is happening in just three days, Echo?"
Echo's golden-streaked hair instantly faded to a solid, miserable gray. He scowled at the ground. "Don't remind me. It's a dragon, then dueling, then merfolk, then whatever Dumbledore has planned for the maze. It's all just… stress." Echo pointed a finger at the telescope. "Now I need more monkey flips."
Shimmer, as if hearing the command, climbed back onto the telescope and, with a fresh burst of energy, backflipped off again. This time he landed with a perfect, four-footed thump, then promptly ran into a cleaning bucket.
James grinned, the predatory gleam of a conspirator returning to his eyes. He leaned in close to Echo, lowering his voice conspiratorially. "Well, we may have thought up a way for you to get out of this event. Quick and easy." James leaned in closer, his voice dropping even lower. "It's simple, Echo. We just need to make it impossible for you to participate."
Echo eyed him warily, the gray-blue of his hair tinged with suspicious violet. "I've already exhausted every option. What else could I try? Wait, are we going to kill someone? And by we, I mean me, right? Because I don't think I'm up for that idea, no matter how desperate I am. Especially after all that's happened with that monster hunter who used to hover around constantly."
Remus shivered, hugging his knees to his chest. "Don't remind me of that whole incident. The man gave me the absolute creeps."
James shook his head emphatically. "No, mate, nothing like that! No death, no permanent injury, no blood, and definitely no Dementor-lite professors. It's something much simpler and less dramatic."
Echo relaxed slightly, the maroon threat in his hair receding. "That's good. Because going into the final task after having dealt with Karkaroff and the fairies… I don't think my mental health can take it."
Sirius shifted, pulling a heavy, leather-bound book from under his cloak. "It's a bit sneaky, but it's a pure, clean, magical solution to a purely non-magical problem."
Remus then reached over Sirius and handed the heavy book to Echo. It was an intimidating volume: Advanced Potion-Making: Potions for the Extreme and Utterly Pointless. A page near the middle was meticulously bookmarked with a strip of parchment.
Echo took the book, his eyes still fixed on the four conspiratorial faces. He slowly opened it to the marked page. At the top of the page, in elegant, swirling script, was the header: The Perfect Stupidity Potion. Beneath it was a detailed, step-by-step guide to its creation.
Echo stared at the recipe, then looked up at the four boys, his eyes widening in disbelief. "Are you four absolutely serious?"
Peter, already looking nervous, stammered, "Uh, sorry. Next page."
Echo frowned and flipped the page. His eyes widened again, this time with a profound sense of shock and immediate, utter comprehension at what he saw. Echo stared at the page for a long, charged moment, then slowly lifted his gaze to meet the four expectant faces of the Marauders. His eyes, the exhausted gray-blue now threaded with a familiar, manic spark of genius, were shining.
"Oh, that is a good plan," Echo stated, his voice low and utterly convinced. "A very sneaky plan."
He leaned back, resting his palms on the cold stone floor, and a slow, delighted grin spread across his face. He inhaled deeply and then let out a sound that started as a low, guttural rasp, quickly built into a sharp, resonant cackle, and finally dissolved into a rich, layered, completely unhinged villainous chuckle. It was the sound of a well-orchestrated catastrophe, dark and deeply satisfying.
The four Marauders instantly tried to join in, but the attempt was a spectacular failure. James's laugh was a high-pitched, honking sound that sounded like a goose trying to cough up a feather. Sirius's was a series of abrupt, explosive snorts followed by a wheezing gasp. Remus produced a soft, intellectual "Heh-heh-heh," which lacked any genuine malice, and Peter's was a nervous, reedy giggle that was instantly swallowed by the chaos. The combined noise was less 'cabal of dark wizards' and more 'flock of severely startled waterfowl.'
In the middle of his own flawless villainous laugh, Echo stopped abruptly and stared at the four of their non-evil laughs, his face a mask of profound disappointment. He let the silence hang for a moment until the Marauders' attempts sputtered out.
"Okay," Echo said, his voice flat with sudden, serious intent. "I really have to teach you four how to evil laugh."
James, still rubbing the tears from his eyes from his own disastrous attempt, instantly took the bait. "Teach us? How do you know how to evil laugh, mate? Did you take lessons from a goblin?"
Echo straightened up, adjusting his robes with an air of unexpected dignity. "James," he lectured, his voice now crisp with professional condescension. "Any Potion Student worth their salt can evil laugh. It's a professional necessity. You have to be able to convey absolute, unholy triumph when your complex, multi-stage brew finally succeeds without curdling, and a regular laugh simply won't cut it. It lacks proper dramatic tension."
Sirius snorted, recovering enough to manage a sneer. "Oh, so like Snivellus, then? Because his laughs always sound like he swallowed a bat."
Echo shook his head slowly. "Snape's is acceptable, but too nasal. It's an Amateur's evil laugh. Good for small-scale successes, like insulting a rival or setting a Gryffindor on fire. But the best one I've heard is not Snape's." Echo paused for dramatic effect. "It's Lily's."
James's face froze in an expression of complete disbelief. "Lily? Evans? Are you serious? I've never heard her laugh like that. She mostly just sighs and glares at me."
Echo nodded solemnly. "Yeah. Hers is really good. It's a pure, unadulterated sound of victorious cruelty. Almost made me pee once."
James's face, which had been a mask of incredulous shock, slowly morphed into an expression of deeply conflicted, dawning realization. He looked off to the side, a slow, deep blush creeping up his neck and across his cheeks.
"Yeah, well," James mumbled, running a hand through his perpetually messy hair. "A really good, victorious-cruelty laugh… that's actually kind of hot."
Echo rolled his eyes, the gold threads of the Felix Felicis long gone, his hair settling back to an exhausted gray-blue. "But enough about your failed love life, Potter. To the dungeons! We have some brewing to do." Echo jumped to his feet, the renewed purpose banishing the last of his sorrowful exhaustion. He clapped his hands together with sharp finality. "This cannot wait. We have three days. Now, let's go gather some questionable ingredients from the Potions storeroom."
