The dungeon was cold, but the heat from the cauldron was a constant, humid presence against Draconia’s skin. She stood at the workbench, watching the silvery liquid swirl under the influence of the glass rod. Harry Potter was the one holding the implement, his knuckles white as he maintained a steady, rhythmic movement. The instructions on the parchment were precise, left by Snape to ensure the potion did not fail during its crucial final hour. It was a long, tedious process that required constant attention, a task that had fallen to them because of a specific, irritating coincidence of scheduling.
"It needs to be a clockwise motion, not a jagged one," Draconia said, her voice cutting through the quiet of the room. She watched his hand, noting the way his muscles tensed in his forearm. He was trying too hard, as he often did, applying too much force to a delicate task. He looked up at her, his glasses sliding slightly down the bridge of his nose. The light from the flames caught the dark, unruly texture of his hair, making him look exhausted.
"I am following the instruction," Harry said, his tone defensive but not unkind. He did not stop the stirring, though his rhythm faltered for a split second. "It says to stir with a steady hand to avoid aeration."
"You are aerating it by being too aggressive with the wrist," she corrected. She leaned closer to the workbench, her robes brushing against the stone edge. The scent of the simmering ingredients was sharp and slightly medicinal, a heavy scent that clung to the back of her throat. "If you keep doing that, the potion will become cloudy before the hour is up. You have to treat it like a living thing, not a chore."
Harry let out a short, huffing breath that might have been a laugh. He adjusted his grip, his fingers splayed wide over the glass rod. "It is just a potion, Draconia. It is not a sentient creature."
"To you, it is a chore. To me, it is a science," she replied. She reached out, her fingers hovering near his hand, though she did not touch him. She wanted to see if he would correct himself without her intervention. He did not, instead, he continued the motion, but it was softer now, more deliberate. He was watching the liquid intently, his brow furrowed in concentration.
"The arithmetic of it is simple," Harry said, glancing at her. "If we both do it, we just get in each other's way. Why did Snape insist we work on this one together?"
"Because he knew you would be too impatient and I would be too perfectionist," she said. She straightened her back, feeling the chill of the dungeon air on her neck. "He wants us to learn how to balance the temperament of the ingredients with the precision of the movement. You have the energy, but you lack the finesse."
Harry tilted his head, a smirk playing at the corner of his mouth. "And you have the finesse, but you spend too much time staring at the bubbles instead of actually doing the work."
"I am observing the bubbles. There is a difference," Draconia said. She reached for a small jar of crushed moonstone, her movements graceful and controlled. She placed the jar back on the shelf with a soft click. "If the bubbles reach the rim, the temperature is too high. You need to watch the heat, not just the motion."
"I am watching the heat," Harry insisted. He looked back down at the cauldron, his eyes tracking the way the silver liquid pulsed. "The flame is steady. The potion is stable. Everything is fine."
"It is not fine if the rotation is inconsistent," she said, her voice dropping a notch. "Consistency is the only way to ensure the ingredients bind correctly. If you miss a single beat, the whole reaction changes."
Harry watched her for a moment, his gaze lingering on the way she stood, poised and rigid. He seemed to be calculating something in his head, a silent tally of her corrections. "You always have a correction, don't you?"
"It is a requirement for success," she said. She felt a flicker of irritation at his casualness, at the way he seemed to treat the delicate process as a mere inconvenience. He was too comfortable in the presence of the liquid, as if he could command it through sheer will.
"Maybe we could just finish it," Harry suggested, his eyes darting to the clock on the far wall. "It has been nearly an hour already. We have three more to go."
"If we finish early because you were careless, we will have to start the entire process over," Draconia reminded him. She took a step closer to him, entering his personal space. The warmth from the cauldron was more intense here, a localized heat that made her feel heavy. "And I have no intention of spending my entire evening in this dungeon because you were too eager to be done."
Harry looked up at her, his green eyes bright in the dim light. "You are very intense about a single cauldron of liquid."
"It is not just liquid. It is a transformation," she said, her voice firm. She watched him closely, noting the way his eyes never quite left her face for long. There was a tension between them that had nothing to do with the potion, a friction that had been building through the weeks of their shared assignments.
"I suppose it is," Harry said, his voice softening. He went back to the stirring, his movements now perfectly smooth and rhythmic, exactly as she had demanded. "It is a transformation of the ingredients, and a transformation of my patience."
Draconia felt a small, involuntary smile tugging at her lips, though she fought to keep her expression neutral. He was trying to be clever, but his deflection was transparent. She watched him work, the way his hands moved with a new-found caution, and she felt a sense of satisfaction. He was a fast learner, even if his initial instincts were clumsy.
"You are doing it correctly now," she observed, her eyes fixed on the swirling silver. "The rotation is consistent. The aeration is minimal."
"Is that a compliment?" Harry asked, not looking up from the cauldron. "Because it feels like you are just documenting my progress like a professor."
"It is an observation of fact," she replied. She leaned back against the edge of the workbench, crossing her arms over her chest. The stone was cold against her back, a sharp contrast to the warmth of the steam. "You are a capable student, Potter. You just need to learn when to slow down."
"And you need to learn when to let a person breathe," Harry countered. He looked at her, a glint of mischief in his eyes. "You are always there, hovering, waiting for the slightest deviation from your perfect order."
"Order is what keeps the chaos at bay," she said. She watched him, her gaze heavy and unblinking. "Without it, you have nothing but a mess of spilled ingredients and wasted time."
"I am not a mess," Harry said, a grin spreading across his face. He increased the speed of the stirring just a fraction, testing her. "See? Perfectly stable. Perfectly orderly. Just like you wanted."
Draconia watched him, her eyes narrowing as she saw the slight wobble in the glass rod. He was testing her, pushing the boundaries of her instructions to see if she would actually react. She took a slow breath, her eyes tracking the movement of his hands as he worked the rod through the thick, silver liquid.
"You are slightly off-center," she said, her voice a low, calm murmur. "But you are still within the acceptable margin of error. Keep going."
Harry laughed, a low sound that seemed to vibrate in the small space between them. He did not stop, though he did not quite reach for the jar again to correct himself. He simply continued the motion, his eyes never leaving the silver depths of the cauldron.
