The bag didn't fight back.

That was the problem with it. Zack had been hitting it for two hours — maybe three, he'd stopped checking his phone somewhere around the second hour when the screen lit up with a name that wasn't hers — and the bag just swayed. Absorbed. Gave nothing back. No resistance that meant anything. No consequence.

He hit it again.

The dojo was dark in the way that old buildings got dark, which was different from the dark of a room with the lights off. It was a settled dark, a dark that had lived here long enough to have texture. The fluorescent tubes overhead had given out months ago, two of the four blown and the others flickering so badly that Zack had unscrewed them himself just to stop the strobing. Now the only light came from outside — the neon bleed of Oakhaven pressing through the windows, the ones that still had glass in them, casting everything in a low amber and pink that made the room look like the inside of something that was almost alive.

Almost.

He was sweating through his shirt. He could feel it at the collar, the small of his back, the inside of his elbows where the skin was thin. His knuckles were wrapped but the wrapping had loosened on the left hand and he could feel the friction starting to build against the fourth and fifth, the familiar bloom of sensation that would become soreness by morning. He didn't stop. The soreness was something to look forward to. It was something that would still be there when he woke up.

Proof that the night had happened.

Oakhaven did not sleep. That was the thing about this city — it had never learned how. Through the cracked window above the far wall he could see the glow of the Lethe District, the bar signs and the transit lights and the pale wash of the elevated rail, and somewhere out there the city was doing what it always did, which was continue. It continued with a kind of aggressive indifference that Zack had come to find personally offensive. Three months and eleven days since Ren, and Oakhaven had not dimmed a single bulb in acknowledgment. The neon still ran. The transit still ran. The people still moved through the streets below in their coats and their earbuds and their ordinary, breathing lives.

He hit the bag harder.

The chain above it groaned.

He stopped.

Not because he was tired. He had moved past tired somewhere in the first hour, into that territory on the other side of exhaustion where the body just runs on something older than energy, some base function that doesn't require permission. He stopped because in the silence between one impact and the next, in that half-second gap where the bag swayed back toward him and his arm was still extended, he heard something.

His name.

Not spoken. Not exactly. More like — the shape of it. The way it used to sound in a particular voice, at a particular pitch, when she was calling him from the other room and didn't want to get up. Zack. Two letters stretched into something warmer than the letters deserved.

He stood very still.

The dojo gave him nothing back. The bag swayed on its chain. Somewhere outside a transit car passed and the building shuddered faintly in its bones, the old response to an old vibration, and then it was quiet again.

Nothing. There was nothing there.

He exhaled through his nose and stepped back from the bag.

The thing about grief — the thing no one had warned him about, not that there had been anyone to warn him, not that he would have listened — was that it was not loud. He had expected loud. He had expected something that announced itself, that had the decency to be dramatic, because at least drama had edges you could press against. What he had gotten instead was this: a persistent, low-frequency absence that sat in the back of every room he entered. Not pain, exactly. More like the negative space where pain had been and left an impression.

Ren had been small. He remembered that now in the way he remembered things he had never thought to memorize — with the slow panic of someone realizing they have forgotten to save a document before closing it. She had been small and she had moved through spaces carefully, like she was aware of taking up room. She had a way of sitting with her knees tucked, feet off the floor, that made her look younger than she was. She had held her tea with both hands even when it wasn't hot anymore.

He was forgetting the small things.

That was what was happening, and he knew it, and knowing it didn't stop it. He could hold the large things — the shape of her face, the particular frequency of her laugh, the way she smelled when she came in from outside in winter. Those were still there, still sharp. But the small things were going the way small things went, quietly and without ceremony, and every time he noticed one missing it felt like a specific, targeted cruelty.

The way she held her tea.

He hadn't thought about that in — how long? When had he last thought about that? It was there now, suddenly vivid, both hands wrapped around the ceramic, steam rising and her eyes on something across the room, not looking at him, just — there. Present in the easy way she had been present when she thought no one was watching.

Had he ever told her he noticed that? The tea thing?

He didn't think he had.

He moved to the wall and leaned against it, letting the concrete take some of his weight. Across the room, the mirror that ran along the east wall showed him a version of himself he didn't entirely recognize: taller than the room seemed to want, shoulders still carrying the tension from the last two hours, hair pushed back with sweat. He looked, he thought, like someone who had decided to be a problem and was committed to it.

Three months and eleven days.

He had come to the dojo every night since the third day after the funeral — the first two he had stayed home because people had been there, coming in and out with food and condolences, and he had smiled at them and accepted both and felt nothing except a low, humming need for everyone to leave. On the third day they had, and he had come here, and he had hit the bag until his hands stopped working properly, and he had come back every night since.

It wasn't helping.

He knew it wasn't helping. He was not confused about that. But it was something to do with the hours between midnight and four when the apartment was too quiet and the quiet had the specific texture of her absence, and doing something with those hours — even something pointless — was better than the alternative, which was lying in the dark and letting the guilt run.

Because the guilt ran. That was the other thing. The grief was the absence, and the guilt was the voice in the absence, and it said things like: *you were there every day and you missed it* and *she was drowning six inches from your hand and you were looking at the horizon* and *you loved her the way you knew how to love and that was not the same as the way she needed to be loved and you never asked what the difference was.*

He pushed off the wall.

He walked to the center of the room, not to the bag, just to the center, and stood there. The neon from outside fell across the floor in long bands of color. He looked down at his hands — the loosened wrap on the left, the faint redness starting at the knuckles. He would be stiff tomorrow. He was always stiff.

In the corner of the room, near the window that faced the street, there was a chair.

It was a small chair, wooden, with a slightly uneven leg that made it rock if you weren't careful about where you put your weight. It had come with the dojo when he'd taken over the space, and he had moved it against the wall years ago and mostly forgotten about it, until Ren had found it and claimed it. She had started coming on nights when she didn't have early shifts, not to train — she had no interest in training — but to sit in that chair and watch him work, her knees up, feet off the floor, sometimes with her phone and sometimes without, sometimes talking and sometimes not.

He had not moved the chair.

He didn't know why. He had moved other things — cleared her things from the apartment with the specific controlled efficiency of someone who knew that if he stopped moving he would not start again. He had done it in a single afternoon, boxes to storage, nothing thrown away, nothing kept out. Clean. He had been very clean about it.

But the chair he had not touched.

He stood and looked at it. It sat where it always sat, in the corner, rocking slightly on its uneven leg in some draft he couldn't locate. Empty. It was a very empty chair. He was aware that this was not a remarkable observation and that he was making it anyway, standing in the middle of a dark dojo at three in the morning making observations about an empty chair, and that this was perhaps not the behavior of someone who was handling things.

He was not handling things.

He had told everyone he was. He had said the words — *I'm okay, I'm managing, it takes time, I know* — with the flat delivery of someone who understood that these were the words that ended the conversation, and that ending the conversation was the goal. He had said them to her colleagues who called to check in and to his own contacts who texted with careful, spaced-out concern, and he had said them with his face arranged correctly and his voice level and his hands still, because stillness was something he had learned young, the way some people learned to swim or to lie: as a survival skill.

Keep the surface calm. Solve the problem. Don't need things.

He had loved her like that. He understood that now. He had loved her with his full attention and his constant presence and his willingness to fix anything that presented as fixable, and he had never — not once, not in all the years — stopped to ask if that was what she needed, because asking felt like admitting he didn't already know, and not knowing felt like a kind of failure he didn't have language for.

So he had not asked.

And she had not said.

And whatever had been living in the silence between those two facts, he was only beginning to understand the shape of it now, now that the silence was the only thing left.

He walked to the door. The old wood swelled in the frame and he had to put his shoulder into it to get it open, the familiar resistance, the familiar give. The landing outside smelled like the building always smelled — old stone, somewhere someone cooking at an hour that didn't make sense, the diesel exhaust of the city drifting up the stairwell. He pulled the door shut behind him.

He stood at the top of the steps for a moment. The street below was quiet by Oakhaven standards, which meant there were only a few people on it. The transit sign at the corner cycled through its colors. A sign across the way advertised something in a shade of blue that had no business being that bright at this hour.

He started down.

On the third step, he stopped.

At the base of the stairs, on the narrow landing just inside the street door, something was sitting on the bottom step.

He looked at it.

It was — light. That was the first word his mind produced. Not an object that was lit. Not a lamp or a screen. Just: light, contained, shaped into something long and thin that he couldn't quite resolve into specifics from here. It pulsed once, very slightly, with the regularity of something breathing.

The stairwell was cold and ordinary around it. The cracked tile of the landing. The row of old mailboxes on the wall that hadn't been used in years. And on the bottom step, this thing — this quiet, luminous thing — that had not been there when he arrived and was absolutely, undeniably there now.

Zack stood on the third step and looked at it for a long time.

His hand had not moved toward it yet.

But he had not looked away.
