The staff tea room in the Ash Annex was not a tea room in any meaningful sense of the term. It was a space at the end of the lower corridor that contained a heating element, a shelf with communal cups, a supply of the cheapest dried tea available through the Records procurement system, and three chairs that had been placed there at some point in the building's history and had never been removed. Marked clerks used the room upstairs. The tea room in the Ash Annex was for Unmarked staff and for anyone willing to be seen using the facilities designated for Unmarked staff, which was a small group.

Cassian was in one of the chairs when she came in for her mid-shift break.

He had his coat on and his hands around a cup, and he was sitting in the way he had always sat in spaces that were not designed for him — with a kind of deliberate ease, occupying the chair fully, as though comfort were something he had decided to perform until it became real. He looked up when she came in and did not look surprised to see her, which meant he had known she would be here at this hour and had arranged himself accordingly.

She got a cup of tea and sat across from him. The heating element made a low sound. Outside the small high window, the Hollow's cycle light was at its mid-point — the flat, even illumination that passed for afternoon in this part of the building.

“You're not supposed to be down here,” she said.

“I come and go,” he said. “It's a skill.”

This was true. Cassian had always moved through spaces that were not designed for him with a fluency that she had attributed, when they were young, to confidence and had since revised to something more technical — he read access points, he assessed what checkpoints actually checked, he understood which rules were enforced and which were performed. It was the same skill as hers, applied in a different direction.

He asked about the work. About the Ash Annex, about the new throughput targets, about whether Orwin was still filing requests for her to be assigned to upper-floor overflow. She answered accurately and without elaboration, because she wanted him to get to whatever he had come to say.

After a few minutes, he set his cup down.

“You're asking about marks,” he said. “Not officially. But you've been talking to Bessa and you've been in sections of the Records that aren't in your clearance range, and Corvin Ash's name is circulating in the Underways network in connection with yours.” He looked at her with the directness he reserved for things he wanted her to take seriously. “I know what that combination means.”

“And what does it mean?”

“It means you're trying to understand what was on the second body. And the first body. And probably the list Corvin was keeping.” He picked up the cup again. “Stop.”

She looked at him. “Tell me why.”

“Not because it doesn't matter. Because you don't know what's on the other side of the door you're opening.” He leaned forward slightly. “There are marks that aren't born. They're made. And the people who make them don't operate on the surface of this city — they operate in the spaces between, where the rules that you know don't apply. If you start pulling on that thread, you will eventually find the people holding the other end. And they are not people who respond well to being found.”

“How do you know this?” she asked.

He was quiet.

“Cassian.”

“I know it,” he said, “the way you know something that you've been close to long enough that you can feel it without having to look directly at it.” He was looking at his cup. “Some things are dangerous to look at directly.”

She looked at his wrist. The cuff of his coat covered it. She had seen the mark move. She had written *Graftmark. Rejected. Name of the anchored called aloud by an outsider — seal broke* in her ledger. She had spent two weeks understanding the mechanics of how a Graftmark worked.

“The mark on your wrist,” she said.

He looked up.

“Is it a Graftmark?”

The silence that followed had a quality she recognized — it was the silence of someone deciding not between truth and lie but between which version of the truth to give.

Then he smiled. It was the real smile — the one she remembered from Little Sky, from the afternoon with Elia, from the years before everything became what it was now. It arrived and it was genuine and it hurt in the specific way that genuine things from before hurt when they surfaced in the present.

“You still read people faster than anyone I've ever met,” he said.

“Is that a yes?”

He did not say yes. He also did not say no. He stood up, straightening his coat with the automatic gesture of someone about to leave.

“I'm telling you to stop because I came up with Alden,” he said. Not looking at her. “Because we grew up in the same place. Because of the things that used to be true before they stopped being true.” He moved toward the door. “Alden is in this with you. I know that. I just want you to know that what you're both moving toward is bigger and more specific than you understand it to be.”

He stopped in the doorway.

“Are you and Alden —” He stopped. Rephrased. “Are you two working together on this? Officially?”

“There is no official version of what we're doing,” she said.

“Right.” He nodded once. “Be careful.”

He left.

She sat in the tea room for another four minutes, which was the remainder of her break. She finished the tea. It was bad tea — dried out, the flavor mostly gone, the only virtue being that it was hot.

In her ledger she wrote: *Cassian confirmed knowledge of Graftmark mechanics. Did not confirm or deny his own mark. Warning genuine — based on direct experience, not secondhand information. Aware of Alden's involvement. Reaction to Alden's name: noted, controlled, present.* She paused, then added: *The warning is real. The question is whether the reason he's giving me is the only reason.*

She closed the ledger and went back to her desk.
