The consommé landed correctly.
He served it in small cups — twenty cups, carried to the tables with the specific logistics he had worked out with Sable — amber and clear and tasting entirely of itself. He watched the table receive it without appearing to watch it, which was a skill he had not known he was developing until he found himself doing it. Neville's expression when he tasted it was the expression of someone encountering something they had not expected to encounter. Dumbledore held the cup for a moment before drinking, which was what someone did when they had eaten very well for a very long time and knew how to assess what was in front of them.
McGonagall looked at her cup. Then at Ron, who was back in the corner preparing the duck. Then back at the cup.
He pretended not to notice.
The table found its rhythm during the starter — the specific warm noise of a group of people who had been given something good and were in the process of relaxing into it. Seamus told a story about a Quidditch match he had apparently been watching from a position that provided him with a uniquely poor view of every significant moment, and the story had the quality of someone who had been telling it in installments and had finally found a table large enough to tell it properly. Dean added to it periodically with the specific contributions of someone who had been there and had a marginally better view. Parvati and Lavender had found common conversational ground with Ginny, which produced a dynamic that was more interesting than Ron had expected, with Ginny characteristically direct and Parvati characteristically precise and Lavender in the role of the person who kept the conversation moving by saying the thing everyone was thinking.
Luna was talking to Lupin about something that appeared, from the quality of both their expressions, to involve creatures that were either very interesting or entirely imaginary or both.
Hermione was talking to Babbling.
This was not surprising — Hermione talked to teachers with the specific ease of someone who had found adults more comprehensible than most of her peers since approximately age eight — but the content of what she was saying was what he noted when he passed close enough to hear it. She was asking about the history of Rune scholarship, the specific question of whether the pre-medieval variants had a consistent underlying grammar or whether they represented genuinely distinct magical traditions. Babbling was answering happily.
Ron served the main courses.
The duck for those who had indicated it, the noodle dish for those who hadn't, and he had misjudged one person's preference and corrected it without ceremony, and the service took twelve minutes total which was longer than he had hoped but within his planned window.
He sat down after the main course had been served, which was the first time he had sat during the dinner, and ate his own food standing at the counter and then sat properly and found that the quality of having prepared something for people and watching them eat it was different from the satisfaction of cooking for himself. More complicated. More worth having.
Neville leaned over.
'Ron,' he said, in the voice he used when he had decided to say something direct. 'This is the best thing I've eaten since my grandmother's roast.'
'Thank you,' Ron said.
'She would want the recipe,' Neville said. 'For the duck. She has very strong feelings about duck.'
'I'll write it out,' Ron said.
Neville nodded, satisfied, and went back to eating with the focused appreciation of someone for whom food was not incidental.
Across the table, Hermione had temporarily set aside the conversation with Babbling — which had migrated during the main course from the history of Rune scholarship to the specific question of whether magical linguistic acquisition changed the underlying neurological structure of the magical brain, which was the kind of question that Hermione would carry home and think about for three weeks — and was looking at him with the expression she used when she had reached a conclusion.
'You've been practicing this since October,' she said.
'The kitchen work, yes,' he said.
'Not just the kitchen work,' she said. 'The planning. The logistics. The invitation cards with the specific reasons.' She paused. 'You designed this.'
'I planned a dinner,' he said.
'You built a room,' she said, which was the kind of thing Hermione said when she was thinking in metaphors, which she did when the literal version of what she wanted to say was too large for a sentence. 'The people, the arrangement, the food — you thought about what would happen when you put these particular people together and you designed it accordingly.'
He looked at the table. At Neville in conversation with Lupin, the specific animation that Neville had when he was talking to someone who was listening to him properly. At Seamus and Dean with their ongoing Quidditch discussion, Harry drawn in by Harry's absolute inability to resist a sufficiently interesting tactical question. At Luna and Babbling, who had apparently redirected to each other when their respective primary conversations paused and were now engaged in something that involved Babbling making notes.
'You're not wrong,' he said.
Hermione looked at the table too.
'How often do you do this?' she said. 'Design things. Situations, not just plans.'
He thought about how to answer this. The honest answer was constantly, which was accurate but would produce a follow-up he was not ready for. The partial answer was more useful.
'I think about how things work,' he said. 'Systems. People are systems in the sense that they have predictable responses to inputs. A dinner is an input. I thought about what I wanted the output to be.'
Hermione was quiet for a moment.
'That's not a normal way to think about dinner parties,' she said.
'I know,' he said.
She looked at him with the expression she had been arriving at since the Burrow — the model-updating one, the one that had been updating since the hospital wing in June and was still adding data points. He had come to understand that Hermione's model of a person was never finished; she treated everyone as an ongoing investigation and considered it both a courtesy and an obligation to keep updating the model as new information arrived. Most people she knew she had been updating for years. He had given her more new information in eight months than most people gave her in a decade.
'I'm glad you invited me,' she said.
'I'm glad you're here,' he said, and meant it entirely and without qualification, and she received it in the way she received things that were true and specific — with a slight shift in her bearing that was not quite relaxation but was adjacent to it, the bearing of someone who had been given something accurate and knew it.
He stood in the corner for a moment after Dumbledore moved away, with the slightly dazed stillness of someone returning from a conversation that had required everything. The room was warm. The candles were at their mid-evening point. Across the tables, the conversations had the quality of things well underway — the self-sustaining noise of people who had stopped needing the occasion to hold them together and were simply in each other's company.
This was what he had designed for. Not the food specifically, not the seating specifically — the quality of a room where the occasion had done its work and receded, where the people were simply themselves rather than guests at a dinner.
He looked at Lupin, who was saying something to Luna with the ease of someone who had found the conversation genuinely interesting and was not managing his response to it. He looked at Neville, who had the specific animation he had when he was certain of himself — certain enough to hold the attention of whoever he was talking to without the habitual qualifying of his own observations. He looked at Harry, leaning into the Quidditch conversation with Dean with the quality he had when he had forgotten to keep anything in reserve.
She went back to the duck. He went back to watching the room.
