The parchment felt rough beneath the tip of her quill, a dry and scratching sound in the quiet of the dungeons. Draconia sat at a small, spindly desk while the dampness of the stone walls seeped into her very bones. She had spent the last hour writing the same line over and over again, her hand cramping from the repetitive motion. The ink was dark and stubborn, much like the mood that had settled over her since the incident in the corridor. Snape stood at the front of the room, his black robes a sharp, dark shape against the flickering candlelight. He did not look at her often, but she could feel his gaze moving when he turned to inspect the shelves of jars.
"The spelling is imprecise, Miss Malfoy," Snape said, his voice cutting through the silence of the dungeon. He did not move from his position near the cauldron, but his presence felt heavy in the small space. Draconia dipped her quill into the inkpot and forced herself to continue the task. She had already written forty lines of the same sentence, and she knew the next forty would be just as tedious. It was a punishment for the outburst, for the red magic and the way she had lost her composure in front of the boy. Harry Potter had been watching her, of course, but Snape was the one who had caught her in the aftermath.
"It will not be, Professor," Draconia replied, keeping her voice steady and level. She did not want to sound defensive, nor did she want to sound repentant. Both were equally useless in this room. She watched the way the ink pooled on the parchment, a dark blotch that threatened to ruin the neatness of her script. She wondered if Harry Potter was thinking about the debt or if he had already forgotten the way she had gripped his collar. The thought of him made her chest tighten with a frustration that she could not quite name.
Snape walked toward her desk, his footsteps silent on the stone floor. He reached out a long, pale hand to inspect the progress she had made on the parchment. The lines were straight, but the ink was slightly uneven where her hand had trembled. "A Malfoy should possess more discipline than a common hex," Snaed remarked, his eyes tracking the movement of her quill. He did not sound angry; he sounded tired, which was perhaps worse than being scolded. Draconia looked up at him, her chin lifted in a way that felt more like a shield than an act of defiance.
"I am working on it," Draconia said, though she knew the lie was transparent. She was not working on discipline; she was working on a way to survive the feeling of being seen. Every time she closed her eyes, she saw the red sparks and the way Harry Potter had looked at her, as if he understood the transaction better than she did. The weight of his gaze was a thing she could not scrub away. She felt as though she were standing in a room with no doors, waiting for the next strike of the bell.
Snape leaned back, his hands clasiding behind his back. "Your father will be pleased to hear of your dedication to your studies, provided you do not spend your time hexing boys in the corridors," he said. The jab was subtle, but she knew it was there. The school knew what had happened, even if they had the details wrong. The rumors were a contagion, spreading through the common rooms and the Great Hall, turning her actions into something scandalous. She could hear the whispers in the back of her mind every time she walked through the corridors.
"The boy was in my way," Draconia said, her voice a flat line of pragmatism. She did not name him, but the name Harry Potter hung in the air between them like a heavy shadow. She did not want to admit that the hex had been a reaction to a feeling, not a physical obstruction. To admit that would be to admit she had lost control of the transaction. If she lost control, the debt was no longer a calculated exchange; it was a mess.
Snape moved to the window, looking out into the dark, subterranean gloom. "A debt is a debt, but one must be careful how one settles it," he said, his voice low. He did not look at her, but the words felt directed at the very core of her. Draconia felt a sudden, sharp urge to stand up and walk out of the room, to leave the ink and the parchment and the damp stone behind. She stayed seated, however, because a Malfoy never left a task unfinished. She was a creature of rules and strictures, even when the rules were being used to punish her.
The silence of the dungeon was broken only by the sound of her quill scratching against the paper. She worked through the second hour of her detention, the ink staining her fingers a bruised, dark violet. She thought of the way the red magic had looked as it hit the stone, a bright, violent streak of color that had felt more like an expression of her soul than a simple spell. It had been a bright, screaming thing, and she had felt a strange sort of relief in the casting. The way Harry Potter had handled her made her feel as though she were a person, not just a name on a contract.
"You are slowing down, Miss Malfoy," Snape observed, his voice cutting through her thoughts. He was standing near the door now, as if he were ready to leave her to her penance. Draconia took a breath, the air in the dungeon feeling thick and cool in her lungs. She looked at the empty lines at the bottom of the page and realized she had nearly finished the task. The exhaustion was settling into her muscles, a dull ache that mirrored the heavched feeling in her chest.
"The ink is running low," Draconia said, a small, useless observation. She wanted to say that she was tired of being a topic of conversation, of being the girl who had made a scene in the red corridor. She wanted to say that she was tired of the way Harry Potter looked at her as if he were waiting for her to break. But she kept the words inside, tucked away where they could not be used against her. She was a master of the unspoken, a practitioner of the silent debt.
Snape walked toward the desk one last time, his shadow stretching long across the stone floor. He did not pick up the quill, but he stood close enough that she could smell the scent of old parchment and dried herbs. He watched her for a long moment, his expression unreadable in the dim light of the single candle. There was a hardness in his eyes that she had seen many times before, a look of a man who understood the cost of things. He reached down and tapped the edge of her desk with a single finger, the sound sharp and final.
"You will spend your life paying for things in the wrong currency, Miss Malfoy."
