Caelum arrived at the cathedral at the time Aurelia had specified in her message: the third hour past noon, when the winter light came through the east gaps at its most useful angle and the cherry trees were at their most active Resonance state.

He had been here before, once, in the first week of the arrangement — Aurelia had required him to see the space so that his description of it to Valerius would be accurate if asked, which it had been, once, and he had given the description Aurelia had briefed him to give. He had not told Valerius that he had already been here. There were many things he had not told Valerius, and he had found, over the weeks of this arrangement, that the list was easier to maintain if he did not enumerate it too often.

He stopped at the cathedral entrance and took a breath.

The nave was lit with cherry blossom luminescence, soft and cold, and the two of them were already working — Valerius at the far end of the nave with Aetheris raised, Aurelia in the middle of the space in the third movement sequence, the Resonance between them visible in the way that strong Harmonic interaction became visible in old Resonance sites: a slight shimmer in the air between two active Cadence Wielders, as if the space itself were slightly more present than usual.

Caelum stood at the entrance and watched for a moment before either of them noticed him.

He had been told, by people whose opinions he respected, that he was a person of steady temperament. Not unfeeling — his commanding officer had once described him as someone who felt things at the normal human intensity but processed them with the discipline of someone who had decided, early in life, that feelings were most useful when they were working for you rather than against you. This description had seemed accurate to him at the time and continued to seem accurate.

Watching Valerius play was, therefore, a thing he felt at the normal human intensity and was currently processing with the discipline of someone who had decided not to let it show on his face.

Valerius was playing differently than he had played at any point in the three years Caelum had been attending his performances. Not technically differently — the precision was still there, the years of training present in every aspect of his bow work. But the quality of attention he was bringing to it had changed. He was not playing at the room. He was playing to her. To Aurelia's movement specifically, tracking it with his musical decisions the way a skilled accompanist tracks a soloist, except that this was not accompaniment — this was a conversation, both of them equally primary, neither of them leading in the conventional sense.

Caelum thought: three minutes was where it started. He had no frame of reference for where this was.

Aurelia saw him first. She did not stop dancing — she had told him that stopping mid-sequence for a social reason was a habit she was trying to break, that it trained the body to treat performance as interruptible, which it was not. But she made a small gesture with one hand, a fluid incorporation of acknowledgment into the movement, that told him she had seen him and that he should find somewhere to be.

He found the altar steps and sat on them.

Valerius saw him on the next upbow — a brief flicker of the eyes toward the entrance, a registration, a return to Aurelia. No pause in the music. Caelum gave him a small nod in the way he had given Valerius small nods since they were eight years old: I see you, I am here, continue what you are doing.

They ran the full arrangement twice while he sat there. He did not have the technical vocabulary to evaluate most of what he was hearing, but he had attended enough of Valerius's performances over enough years to have developed a functional ear for the difference between Valerius performing and Valerius playing. He had not heard the second thing since before the funeral. He was hearing it now.

At the end of the second run, the silence that followed had the specific quality he associated with good endings — not the relief of conclusion but the resonance of completion, the sense of a thing that had arrived where it was supposed to arrive.

Aurelia came toward him first, which was correct — he was nominally here to see her, and she had the social management of this interaction to perform.

Caelum, she said, and her voice had the warmth she deployed for him, the particular register of someone speaking to a person they were pleased to see. She had briefed him on this register and he had practiced receiving it, and by now they were both reasonably fluent in the fiction.

Aurelia. He stood. You sounded — he paused, reaching for a word that would serve both the fiction and the truth — extraordinary.

She smiled. We have been working very hard. She glanced back toward Valerius, who was packing the violin with the focused care he brought to the process. He has been — she paused, and the pause was not the calculated one he had learned to recognize, but something more genuine — he has been remarkable.

Caelum looked at her. She was looking at Valerius.

He filed that away.

Valerius came toward them, and Caelum arranged his expression into the easy friendliness he had been practicing. Valerius, he said.

You are here early, Valerius said.

I finished my afternoon reports ahead of schedule. He looked from Valerius to Aurelia and back. The piece sounds ready.

It has been ready for two days, Valerius said. We are refining.

That sounds like you, Caelum said, which was entirely true and required no performance.

Aurelia had moved slightly — not away from either of them, but into the particular arrangement of people in a space that communicated ease, the natural distribution of three people who were comfortable together. She said something about the third movement, asking Valerius a question about the new bars, and Valerius answered with the focused brevity he used when discussing work, and Caelum stood between them and watched and felt, with the discipline he had cultivated, the thing he was not supposed to let show.

Valerius was different with her.

Not in an obvious way — not in the way that would read as anything definitive to a casual observer. But Caelum had spent twenty-one years being Valerius's closest friend and he knew how Valerius stood in rooms, how he oriented himself relative to other people, where he put his attention and for how long. He knew the specific quality of Valerius being present versus Valerius being physically in a space while mentally elsewhere. The second had been almost universal since the funeral. The first was what he was seeing right now, directed at Aurelia Thorne, sustained and specific.

Aurelia laughed at something — a genuine laugh, not large, the small one that came out when something caught her off guard. Valerius's expression did not change in any way that Caelum could have described to someone else. But the set of his shoulders shifted by perhaps two degrees, and his eyes stayed on her face for exactly one second longer than the situation required.

Caelum turned and looked at the cherry trees.

He thought about the message he had received that morning: the joints in my left hand have been stiff for six days now, not four. The preparation Elowen gave me is helping but the rate of progression has increased slightly. Do not tell him. Not yet.

He thought about what Lysandra had said to him six weeks ago: I am not asking you to save me. I am asking you to help me save him.

He thought about the way Valerius's shoulder had shifted two degrees when she laughed.

The cherry trees were very beautiful in the afternoon light, their white blossoms luminescent and still.

He stayed for another twenty minutes, performed his role with the competence he had developed over six weeks of practice, said his goodbyes with the warmth appropriate to a man who believed he was the subject of someone's romantic interest, and left.

On the walk back to the barracks he stopped once, on the bridge over the lower canal, and stood with his hands on the railing for a while looking at the water.

He was going to be terrible at this.

He was going to do it anyway.
