Damian sits down last.
"You came here," he says to Marcus. "Tell me why. Not what I already have on you. What you're choosing to give me that I didn't already take."
Marcus looks at the board again. There is an empty space under Delaney's name, wide enough to look deliberate. Another name, further right, written more recently than the rest.
The Fighter.
Undefined.
Undefined.
"At one forty this morning," Damian says, following his eyes, "I learned that the Fighter is back in Chicago."
His attention moves to the name on the board. For a moment the bright, alert quality of him becomes almost nakedly uneasy.
"I had set his absence to zero. Sensible simplification. Elegant, even. Rowan's team never touched him at all, which I considered, at the time, one clean edge of an otherwise messy case. Then a zero term became a living man, in the same city as the person whose entire recent trajectory has been orbiting him. Undefined. A division by zero. Very bad mathematics."
Marcus looks at him.
"You knew he was gone."
"I knew he had vanished. I treated that as a fixed condition. I should not have. It is, I am realizing tonight, a pattern with me — mistaking the edge of what I can see for the edge of what exists."
Viktor watches Damian now, not as if he trusts him, but as if he is trying to learn what kind of person admits a mistake before anyone has made him.
"What does any of that have to do with Cut Ties?" Marcus asks.
"That is what I need help understanding. Delaney's fixation did not end when he disappeared. It changed form. The café surveillance. The people close to him. The way she continued to arrange information around an absence. Rowan's investigation caught the outer edge of that pattern and called it obsession without ever getting close enough to understand its shape. I need the inside of it. That is what you have and Rowan never did."
Marcus closes his eyes for a second.
"She made him administrative."
Damian does not interrupt.
"That was what she did when a person got too close to the centre of something. She stopped saying the name. She made a file. A schedule. A list of people who might be useful later. If anyone asked, she said it was nothing we needed to worry about yet."
"Did anyone in Cut Ties know he was back?"
"Not that I know of."
"Did Delaney?"
Marcus opens his eyes.
"I do not know."
He does not improve the answer. He does not give it a useful edge.
"But if she did," he says, "she would not have announced it. She would have started correcting the world around it until it looked like she had been expecting it all along."
Damian writes that down. Then stops himself.
"That is an observation," he says. "Not a prediction."
Marcus looks at him.
"Good."

Viktor's hands have found each other in his lap.
"She corrected my writing."
Both men turn toward him.
Viktor keeps looking at the table.
"She gave me a notebook when I came to the apartment. She told me to write what I noticed. Every day. Then she read it and crossed out anything that sounded upset. She wrote something calmer over it."
Damian's pen remains still.
"Did she tell you why?"
"She said upset was noise. It got in the way of the record."
For the first time since they entered, Damian's enthusiasm fails him completely.
"Oh," he says, but there is no delight in it now. "That is not editing. That is the system teaching itself to erase its witnesses. Rowan and I built an entire counter-investigation around what Cut Ties did with information. We never once thought to ask what it did to a nineteen year old's diary."
Marcus feels something turn over in him.
There it is. The thing he had watched from the adult side of the room and called editing. The same mechanism, smaller and closer to the bone. Delaney taking a frightened boy's language and making it tidy enough to be useful.
Damian does not reach for the pen.
"Do you have the notebook?" he asks.
Viktor's shoulders pull tighter.
Marcus says, "You do not have to answer that."
Damian looks at Marcus, then at Viktor.
"He is right. You do not."
Viktor takes a breath.
"It is in the car."
Marcus looks at him.
Viktor does not look back.
"I did not bring it in."
"Okay," Damian says.
Nothing follows. No request. No reason why he should reconsider. No careful pressure in the shape of gratitude.
Viktor looks up slowly.
"It might help you."
"It might," Damian says. "And it might cost you something to let us have it. Both things can be true. You do not need to decide tonight."
Viktor stares at him.
The sentence seems to arrive in the room before he has decided whether to believe it.
Marcus watches his face. He wants to say something. He wants to tell Viktor that he does not have to give the notebook to anyone, that a police office cannot make Delaney's rules become real again, that he will get up and leave if anyone tries.
But Viktor already knows this. Marcus told him in the car.
So he does not repeat it.
He just stays in the chair beside him.
Mistaking the edge of what I can see for the edge of what exists.
That is not editing. That is the system teaching itself to erase its witnesses.
He just stays in the chair beside him.
