The room had no windows. It had no doors either, not in any conventional sense. There was a space in the wall where a door should be, and a man stood in that space, but he was not a guard — he was something else, something between a person and a function, wearing a trench coat that had seen too many rains and speaking in a voice that was neither warm nor cold.

Cara sat on the concrete floor. She had been sitting on the concrete floor for what she assumed was the third day in a row, though the days were difficult to count when the light above flickered on and off without schedule and no one bothered to tell you what time it was.

The man stood in the doorway. He had no name or at least he would not give you one. He was not the manager of the facility — that title belonged to someone else, or to no one, or to the room itself, which seemed to manage itself in a way that suggested a system with no architect.

Cara had been here before. She had been here many times. Each time she woke on the concrete floor, in the same position, wearing the same clothes. The man would stand in the doorway. He would say certain things. She would say certain things. He would propose modifications. She would refuse. He would leave. She would try something. She would end up back on the floor.

It was a loop. She knew that. She had discovered the concept the first time — or the last time, depending on which way you counted — when she had woken on the floor and thought: I have done this before. And when she tested it — remembered conversations she hadn't yet had, recalled events that were about to happen — she confirmed it.

Not a dream. Not a delusion. A loop.

On this iteration, the man stood in the doorway and said: "We would like to discuss the modification options."

Cara looked at him. Her face was tired. She was tired of being tired. "How many options?"

"Three standard options and one experimental option."

"Three standard and one experimental. That always surprises me. The experimental option is always the one that hurts the most."

The man did not smile. He didn't have the expression for it. "The experimental option is also the most thorough."

"Thorough. Yes. I suppose that's the word." She stood up and stretched. Her body was her body — no modifications yet, or at least not this time's modifications. She had the strange satisfaction of knowing that every modification she received was temporary. Each time the loop reset, her body reset with it. The changes were erased. The pain was erased. Everything was erased.

Except her memory.

Her memory was the one thing that carried over. She had tested that — in iteration four or five or whatever it was, she had intentionally damaged herself and then woken up the next time with no damage. Her body was fine. But her memory of the pain was sharp, immediate, present. The loop couldn't erase that. The loop couldn't erase her.

"What would you like to do today?" the man asked. The question was not rhetorical. He was required to ask.

Cara sat back down on the floor. "I don't know. Negotiate? Fight? Sleep? There's not much variety in the menu."

"Sleep is an option," the man said.

"Not really," Cara said. "Sleep just means you reset sooner."

She had tried everything. In early iterations — she estimated somewhere between ten and twenty before she lost count — she had tried everything the system expected her to try. She had negotiated with the man, pleading, reasoning, bargaining. She had fought — physically attacked him, threw objects at the walls, screamed until her throat bled. She had attempted self-harm, which turned out to be meaningless in a loop where every wound healed. She had tried silence — refusing to speak, refusing to move, refusing to respond to anything.

Silence had been the closest she'd come to something that felt like progress. The man had stood there, confused, repeating his offers, and for a few seconds — a few precious seconds — she had felt something like power. She was the one choosing not to engage. And in not engaging, she had taken something from the system.

But the system was patient. It would wait. Eventually, she would speak eventually, she would move, eventually, she would break.

Not this time.

On this iteration, she sat on the concrete floor and leaned against the wall and closed her eyes.

The man stood in the doorway. He spoke. She did not respond. He repeated his offer. She did not respond. He waited. She did not respond.

The fluorescent light above flickered. On and off. On and off. A broken thing in a broken room in a broken world with no windows and no doors and no exit and no beginning and no end.

She sat.
