The room filled in the way of rooms at gatherings where most people know most other people — not all at once, but in accumulating warmth.
His mother arrived with his father, Ginny, and Percy, and immediately identified the thing about the room that needed doing — which was that the bread had been placed at one end of the table and needed redistributing — and did it without being asked, which was his mother. His father found the fire and stood near it with the quality of a man who had always preferred the near-fire position at any gathering and did not consider this worth explaining.
Fred and George came together, slightly late, with the precise quality of people who had discussed their arrival time and decided five minutes behind schedule was the correct aesthetic choice. They had brought Neville a small package that he opened with the wariness of someone who had received Fred-and-George packages before. It turned out to be a propagation pot with a tiny plant in it that, when Neville leaned close, said 'Happy birthday' in a voice that was somewhat deeper than the plant's size suggested. Neville laughed, which was the correct reaction.
Hermione arrived with Luna. They had apparently met at the Floo and come up together, and they entered with the ease of two people who had discovered, in the five minutes since introduction, that they had more in common than the surface suggested — which Ron had expected, because he had thought about it and arrived at this conclusion approximately two months ago. Luna was wearing robes in a colour between yellow and green that had no standard name, with what appeared to be radishes at her ears. She looked at the room with the quality she always had — interested in everything, alarmed by nothing.
Lupin came with Sirius.
They arrived together in the way they apparently always did when they arrived together — with the ease of two people who had a great deal of history between them and had arrived, after some years of difficult terrain, at a version of it that was simply glad. Sirius had the open quality he carried when he was with people he had chosen. Lupin had the more contained version of the same thing — warmth held carefully, the quality of someone who had learned that warmth was something to be rationed and was, tonight, allowing himself not to ration it.
Harry arrived last, which had not been planned but was the correct order.
He came through the door and found fourteen people in a lit room, all of whom were there because today was his birthday, and he stood in the doorway for a moment with the expression Ron had been watching for.
Sirius crossed the room and put a hand on his shoulder. He didn't say anything. He didn't need to.
'Happy birthday,' Ron said, from across the room.
Harry looked at him. The expression resolved into something that was not quite composed but was trying to be, in the specific way of someone who had not been taught how to receive things and was doing their best. 'Thanks,' he said, and came the rest of the way into the room.
The food was good in the uncomplicated way of a kitchen that knew what it was doing and had not been asked to do anything beyond that. Roast beef, which Tom had clearly decided was the correct choice for a birthday dinner in late July, with the authority of something that had been in the oven the right length of time and had not been interfered with. Roasted potatoes with rosemary. A soup to start that was thick and warm and received no complaints from anyone, which was its own kind of praise.
The conversation had the quality it always had when the right people were in the right room — not loud, not performed, but sustained in the specific way of people who were genuinely glad to be where they were and did not feel the need to demonstrate it by volume.
Fred had seated himself next to Augusta Longbottom, which had either been accidental or the boldest strategic decision of the evening. Within ten minutes they were in a conversation that Ron could not fully follow from across the table but which involved, at one point, Augusta producing a small card from her bag and writing something on it and handing it to Fred with the quality of someone issuing instructions. Fred read it, looked at George, and nodded once with the expression of someone who had received useful intelligence.
Neville, watching this from beside Ron, had the expression of someone whose two worlds had just made unexpected contact.
'Is she giving him advice?' Neville said.
'It appears so,' Ron said.
'Gran gives advice,' Neville said. 'It is generally good advice. She just doesn't ask first.'
'Fred doesn't appear to mind,' Ron said.
Neville looked at the exchange with the quality of someone updating their model of a person they had known their whole life. 'No,' he said. 'He doesn't.'
Lupin and his mother had found each other at the near end of the table and were in what appeared, from the quality of their attention to each other, to be a conversation about teaching — the specific posture of two people comparing notes on a shared subject, animated in the particular way of professionals who have found an unexpected peer. Ron filed this.
His father and Sirius were talking about the Jaguar, which his father had apparently mentioned in a letter and Sirius had apparently responded to with the specificity of someone who knew the model and had opinions about the gearbox. This was not a conversation Ron needed to be part of.
He looked at Harry, who was next to Lupin and was in the particular state Ron recognised — present, attending, trying to be enough at ease for the occasion and slightly behind it. Luna was on his other side and was telling him something about a creature she believed nested in the roof spaces of old wizarding inns that was visible only in firelight and had been responsible for a number of historical accounts of 'inexplicable good feeling.' Harry was listening with the expression he had when something was improbable but Luna's conviction was hard to argue with.
Ron took a photograph: the long table, the candlelight, everyone in it. Not framed carefully — there wasn't room to frame carefully — but accurate. He would know what it was for when he developed it.
