He asked McGonagall on Monday of the third week.
Her office had the contained precision of someone who had organized their physical space with the same thoroughness they brought to everything else.
'I'd like to host a dinner,' he said. 'For friends and some staff. Toward the end of the month. I'll cook the food myself — I've been learning, and I want to practice for a group. I need a room and I need permission.'
McGonagall looked at him with the expression she used for things she had not anticipated and was now categorizing.
'You want to cook dinner,' she said. 'For staff.'
'For friends primarily,' he said. 'The staff would be guests. I'd like to invite you, Professor Lupin, Professor Babbling, and Professor Dumbledore, if he's willing.'
The silence had the quality of someone recalibrating.
'You intend to cook the food yourself,' McGonagall said. 'Not request the kitchens to prepare it.'
'I'll use the kitchens to prepare it,' he said. 'I've been working there on Saturday mornings. The head elf has been very patient with me.' He paused. 'I want to do the cooking. The room and the occasion just need permission.'
McGonagall looked at him for a moment with the expression that was not quite the controlled warmth she gave good students and was not quite the exasperated disbelief she gave Harry things. It was the third expression — the one he had seen in the suit of armour photograph. Older. More personal. The expression of someone who had been at this castle for a very long time and occasionally encountered something they had not seen before.
'I will arrange a room,' she said. 'Saturday the twenty-eighth. The Transfiguration classroom is available that evening. I'll have the desks cleared.' A pause. 'I accept your invitation, Mr Weasley.'
'Thank you, Professor.'
'The other staff,' she said. 'You mentioned Dumbledore.'
'I thought he might like to be included,' Ron said.
McGonagall looked at him. 'Yes,' she said, after a moment. 'I imagine he would.'
He thanked her and left. In the corridor outside her office he stood for a moment with the sensation of having cleared a necessary obstacle — not that McGonagall had been an obstacle, exactly, but that she had been a gatekeeper and the gate had opened in the direction he had expected it to and on the terms he had prepared for.
The conversation had gone well. He had watched her face during it the way he watched most faces — with the attention he had developed over the autumn for the specific language of how people held themselves when they were updating their understanding of something. McGonagall had arrived at the meeting expecting a student with a request that would be either straightforward or inconvenient. She had encountered something that did not quite fit either category and had handled the misfit with the specific grace of someone who had been surprised by students before and had long since decided that the correct response to genuine surprise was to proceed with interest rather than scepticism.
He appreciated this about her. He had been appreciating it since the suits of armor photograph.
He went back to his dormitory and sat on the edge of his bed and thought about the guest list.
The principle was people whose presence at a table he could account for — not people he liked, not people he was trying to impress, but people whose company would produce something worth having. A dinner was a system, in the same way a kitchen was a system: the ingredients mattered, and the proportions mattered, and the question of what went with what was the question that determined whether the result was coherent or merely busy.
He thought about Luna. He had found her shoes in October — had found them and returned them without ceremony, which seemed to be the correct approach — and she had thanked him in a way that was not quite a thank you and not quite a statement of fact but something in between. She had a quality he had been trying to name for months: a way of being present that was entirely undefended, that did not perform warmth or perform indifference but simply occupied its own space with the specific confidence of someone who had decided that the standard social armour was optional and had declined to wear it.
He found this quality easier to be around than most people found it. He suspected this was partly because his own Occlumency meant he had a version of the same thing — an interior that was contained and not easily reached — and two contained people could occasionally be comfortable in proximity in a way that was difficult to achieve with people whose interiors were more visible.
He thought about Neville, who had identified the Mandrake problem in September and had looked surprised when Ron noted it. The surprise had been genuine — Neville was not accustomed to being seen doing things correctly before he had been corrected, and had developed, accordingly, a habit of assuming his correct observations were mistakes he had not yet identified.
Ron had been making a point of noticing when Neville was right. It did not require effort. Neville was frequently right.
He thought about Parvati and Lavender, who were in his peripheral vision primarily through Hermione and who had, on closer observation, turned out to be more interesting than the peripheral vision had suggested.
Parvati had the quality of someone who was very good at a social register that other people underestimated — the management of group dynamics, the reading of what a room needed and the provision of it, the intelligence that expressed itself in interpersonal precision rather than academic precision.
Lavender said true things in the voice of someone who was not aware she was saying them, which was its own kind of remarkable.
Both of them would be good at a dinner table.
He wrote the final list in his notebook. Twenty people including himself: four core friends, five additional students, four teachers, and the elves who would be present but not at the table.
The elves were not invisible to him. They were present. They were doing the work that made the dinner possible. He would acknowledge this in his own way.
He closed the notebook.
Three weeks to the dinner. One week to plan the menu, two weeks to practice it. The consommé was solved. The duck he would begin Thursday. The tarte tatin he had made once and would make twice more before Saturday the twenty-eighth.
He was ready to begin.
He went to the kitchen that evening and told Sable about the room and the date and the number of people. She listened with the attention she gave things she considered relevant and then asked three questions: how many courses, what temperature the room would be maintained at, and whether he wanted the elves to be visible during service or working from behind the serving area.
He had not thought about the third question. He thought about it now. Visible, he said. They were part of the dinner. Sable nodded once and said she would arrange accordingly.
