The Great Hall was a cavern of shadows and floating light, far too large for the two of them to fill. Harry sat on the long, wooden bench of the Slytherin table, his posture stiff and his eyes fixed on the empty space before him. He looked like a man waiting for a sentence to be passed, or perhaps a man waiting for the floor to open up and swallow him whole. Beside him, the silver cutlery gleamed dully in the low light, untouched and cold. The silence of the castle was not a hollow thing; it was a heavy, physical presence that seemed to press against his eardrums.
Harry watched her move. Harry Malfoy was not a man who moved without purpose, and neither was Harry Malfoy a man who allowed himself to be seen in such a state of undress. She had discarded her outer robes to sit more comfortably, her silk slip clinging to her skin. She moved a heavy, high-backed chair from the end of the table, dragging it across the stone floor with a screech that felt loud enough to wake the dead. She did not care about the noise. She turned the chair around, lacing her fingers together and resting her chin on her knuckles.
"You look like you are waiting to be executed, Potter," she said. Her voice was steady, lacking the jagged edges of the girl he had known in earlier years. She sat with the chair's back to the table, her arms resting on the top of the wooden frame. This position made her look taller, more commanding, even as she sat in the middle of a room meant for hundreds.
"I am just waiting," he replied. He shifted his weight on the bench, his knees bumping against the underside of the table. "I did not think you would actually make me sit through this. I thought you were joking about the time."
"I do not joke about time," she said. She leaned forward, her chin still resting on her hands. "Time is the only thing we have left that is actually ours. The rest is being carved up by people who do not even care if we live to see the end of the term."
"That is a very grim way to start a midnight visit," he said. He looked up at the floating-candle ceiling, where the light flickered with a slow, rhythmic pulse. He wanted to reach out and touch the air, to see if the magic felt as cold as the stone beneath him.
"It is an honest way to start a conversation," she countered. "If we are going to spend our time together in the dark, we might as well be honest about how much of it we are losing."
He watched the way her hair caught the light. It was a pale, shimmering thing in the dimness of the Hall. He felt a strange tightness in his chest, a sensation he could not quite name. It was not the sharp ache of longing, but something broader and more hollow.
"What is the agenda, then?" he asked. He reached out and traced the grain of the wooden table with a finger. "Since you have gone to such lengths to drag me down here in the middle of the night. What is the plan for the next few hours?"
"First, we will talk about things that do not matter," she said. She reached out and adjusted the position of her chair, the wood scraping softly. "We will talk about the weather, or the tea, or the way the corridors feel too narrow when you are walking alone. We will fill the time with trivialities so that we do not have to speak of the things that actually matter."
"And then?" he asked. He knew there was a second part. There was always a second part with her.
"And then we will speak the truths," she said. Her eyes were bright, catching the amber glow of a nearby candle. "We will speak the things that we are too afraid to say when the sun is up and everyone is watching us play our parts. We will say the things that would get us killed if we said them in the light."
"You are very good at scheduling a descent into madness," he remarked. He leaned back, trying to find a comfortable position on the hard bench. The wood was unforceably unyielding.
"It is a survival mechanism," she said. She moved her chin from her hands, stretching her neck. The movement was fluid and graceful. "If we control the structure of the conversation, we can control the impact of the truth. It is easier to fall if you know exactly how far the ground is."
"You have always been a strategist," he said. He felt a sudden urge to reach across the table and grab her hand, but he kept his fingers still. He did not want to break the stillness of the room. "Even now, you are trying to map out the darkness."
"The darkness is predictable if you know how to navigate it," she replied. She looked toward the doors of the Great Hall, which stood closed and heavy against the night. "The shadows are just the absence of light. They do not have a will of their own. We are the ones who give them meaning."
"I do not think the shadows in this castle have much of a will, but they certainly have a presence," he said. He looked at her, really looked at her, noticing the way her breathing was slow and even. She seemed entirely at home in the void. "Are you sure you want to do this? To sit here and dissect everything?"
"I am sure," she said. She leaned back slightly, her spine straight against the chair. "I am tired of pretending that the silence is comfortable. It is not comfortable. It is a void that waits to be filled."
"It is a very large void," he said. He felt the weight of the castle pressing down on the Hall. The stone walls felt closer than they had a moment ago.
"Then we will fill it," she said. She looked at him with a fierce, unwavering gaze. "We will fill it with whatever we can manage."
He watched as she reached out to a small, flickering candle that floated near the edge of the table. She did not touch it, but she watched the flame dance for a long moment. The light reflected in her eyes, making them look gold and fierce. He felt a sudden, sharp pang of something that felt like grief, though he could not say why.
"You are a very strange woman, Harry," he said. He felt the tension in his shoulders begin to ebb, replaced by a weary sort of acceptance. "Most people come to the Hall to eat or to sleep. You come here to build a fortress out of nothing."
"A fortress is better than a grave," she said. She turned her gaze back to him, her expression unreadable. "At least in a fortress, you can still fight."
"Is that what we are doing?" he asked. "Fighting?"
"We are surviving," she said. She sat perfectly still, her hands resting on the edge of the chair once more. "And survival requires a certain amount of discipline. It requires knowing exactly how long you can stand to be alone."
"How long is that, exactly?" he asked. He wanted to know the limit. He wanted to know how much of her he was allowed to see before the walls came back up.
"It depends on the candle," she said. She gestured vaguely toward the floating lights that drifted through the air above them. "The light is the only thing that tells us how much time is left. We are not here to stay all night. We are here to be here."
"I suppose that is enough," he said. He felt a strange sense of peace. The fear of being caught had faded, replaced by the sheer absurdity of the moment.
"It is more than enough," she said. She leaned forward, her eyes narrowing as she watched the flame of the nearest candle. "You have a deadline, Potter. Do not forget it."
"A deadline?" he asked. "
