The Great Hall on the night of the Yule Ball had the quality of a place that had decided to be entirely itself.
He had seen the Hall in most of its configurations — the ordinary feast warmth, the specific charged quality of examinations, the particular atmosphere of something significant happening. This was different from all of them. The decorations had the quality of winter rendered as something worth celebrating rather than something to be endured: the ice sculptures catching the candlelight, the ceiling showing the clear December sky with its particular depth of cold stars, the floor cleared and the tables arranged for the occasion.
He stood in the entrance with Hermione beside him and looked at it.
She was in the periwinkle gown, which in the candlelight of the Hall was the precise colour he had thought it would be when he first saw it in Madam Malkin's window — not blue, not purple, but the specific place between them that had its own name and its own quality. The bodice was worked with detail that caught the light as she moved. Her hair was up in a way that had required thought and had been given it, the starflower pendant at her collarbone where it always was.
She looked at him.
He was in the black tailcoat with the deep purple lapels and waistcoat and tie, the white shirt, the lining of the coat that was visible only in movement — the dark purple floral on black ground. He had been fitted for it three times and it sat on him the way things sat when they had been made right.
'You look — ' she started.
'So do you,' he said.
She smiled the specific smile she had when she had been given something accurate. She took his arm and they went in.
Harry and Ginny were already there. Harry in deep green dress robes that worked with Ginny's in the specific way of two people who had been paying attention to each other. They looked exactly like what they were — two people who were genuinely glad to be there together and were not performing the gladness.
Neville arrived with Luna, who was wearing robes in a shade of silver that moved in the candlelight with the quality of something chosen by someone who understood that the right colour for Luna Lovegood was whatever colour did not pretend to be ordinary. Neville had dress robes in dark blue that fit him properly for what Ron suspected was the first time in his Hogwarts career, and he was pink in the good way, and Luna had taken his arm with the serene confidence of someone who had agreed to be somewhere and intended to be entirely there.
The champions' opening dance was first.
Harry and Ginny on the floor with Krum and his partner, Fleur and her date — a Beauxbatons boy who had the quality of someone who had been asked and had said yes and was attempting to be equal to the occasion. The music started and the floor opened and Ron watched Harry navigate it with a capability that had not been there in August and which Ron attributed, without claiming credit, to three months of footwork drills that had built physical grammar Harry was now applying to a purpose he had not originally intended.
Ginny, who had been dancing since she could walk, led when she needed to and followed when she didn't, and the result was the specific ease of two people who had found a physical frequency the same way they had found a conversational one — without needing to negotiate it.
Fleur danced with the quality she brought to everything: entirely herself, entirely present, the grace of someone whose magic included the way they moved through space.
Krum was not what he had expected. The economy of movement that made him formidable on a broomstick did not translate directly to dancing, and what it produced instead was something more effortful and more genuine — the specific quality of someone doing something that did not come easily because the person they were doing it with was worth the effort. Ron filed this alongside the other Krum observations.
Then the floor opened and he held out his hand to Hermione.
She took it.
He had practiced. Not extensively — he was not a natural dancer and had not pretended to be, but he had spent two evenings in the Room of Requirements with the methodical approach he applied to things that required physical grammar he did not yet have. The footwork was correct. The frame was correct. The rest required only paying attention to the person in front of him, which was something he had been doing since second year and which was, by December of fourth year, the most natural thing he knew how to do.
She was better than him. He had known this and it didn't matter. She had grown up with dancing lessons and had a technical foundation he was not going to match in two evenings, and she compensated where she needed to with the ease of someone who was interested in the dancing and more interested in who she was dancing with.
At some point she said, very quietly: 'You practiced.'
'Two evenings,' he said. 'In the Room.'
'I know,' she said. 'I checked.'
'Of course you did,' he said.
'Of course I did,' she agreed, and she was smiling — the real one, not the managed one — and he thought: this. This is the one I'll remember.
He took a photograph at some point in the middle of the evening — the whole Hall from the side, the dancing floor and the tables and the candles and the ice sculptures and the three schools occupying the same space with the ease they had arrived at across the term. All of it.
Later, in the particular warmth of the evening after the dancing, he sat with Hermione and Harry and Ginny and Neville and Luna at the table they had claimed, and there was food and good conversation and the specific quality of an evening that was going exactly as it should.
Fleur stopped at their table on her way past.
She had the quality she had at the medic tent — the composure and the assessment and underneath both the warmer thing. She looked at Ron and Hermione with the expression she had worn when she told Hermione she was a lucky girl, and the expression said: yes. Still.
'A good evening,' she said, to the table generally, and then to Ron specifically: 'You dance adequately.'
'High praise,' Ron said.
'It is meant as such,' Fleur said, entirely seriously, and moved on.
Hermione looked at him.
'Adequately,' she said.
'I'll take it,' he said.
She was smiling. The starflower pendant caught the candlelight. The Hall was warm and full and the evening had the quality of something that would be in the album — not the formal record of the occasion but the specific true thing of it, the way the six of them were in it together, this specific December night.
He danced with Ginny in the second half of the evening.
It happened without requiring arrangement — Harry had gone to get drinks, and Ginny was at the edge of the floor watching the Beauxbatons students demonstrate something that appeared to involve both partners being briefly airborne, and he offered his hand with the ease of someone who had known her since before she could read and had spent a summer watching her fly.
She took it and they found the floor.
Ginny danced the way she flew — with the specific physical ease of someone who understood where their body was in space and had made peace with that knowledge. She was better than him. She was also, he noticed, considerably more relaxed than she had been at the start of the evening, which told him something about how the earlier part of the night had gone.
'He's a good dancer,' she said. Meaning Harry, without needing to specify.
'He practiced,' Ron said.
She looked at him. 'Did you make him practice?'
'The footwork drills translate,' he said.
She was quiet for a moment, moving through the music with the ease she brought to everything physical. 'You're ridiculous,' she said.
'The footwork is applicable to multiple contexts,' he said.
She laughed — the real one — and he thought: she's going to be alright. Whatever this year brings, she is going to be alright.
He danced with Luna next, which required a different approach — Luna's relationship with music was genuine but idiosyncratic, and she moved through it in the specific way she moved through everything, which was to say according to principles that were entirely her own and entirely coherent if you understood them. He had learned, over a term of training sessions, to trust her physical instincts rather than correct them, and the result was something that was not quite any recognized dance form but was not nothing either.
'The suits of armor did very well at Christmas,' Luna said, while they were dancing.
'I've heard,' he said.
'The third song was the right choice,' she said. 'Silent Night. Everyone has a version of it in their head. Even people who don't know they do.'
'That was the point,' he said.
She looked at him with the quality she brought to things she found accurate. 'Yes,' she said. 'I know.'
They finished the dance and he walked her back to where Neville was waiting with the specific look of someone who had been content watching and was now glad she was back.
Fleur found him near the edge of the floor later in the evening.
She had the quality she always had — composed, certain — but there was something slightly looser in it at this hour, the specific ease of someone who had been enjoying an evening and was not managing the enjoyment. She looked at him with the assessment she had been running since the medic tent.
'You dance adequately,' she said.
'I've heard,' he said.
'Better than adequate with Hermione,' she said, with the precision of someone making a technical distinction. 'Different quality. You were paying attention differently.'
'Yes,' he said.
She accepted this. 'The girl in green,' she said, meaning Ginny. 'She dances well.'
'She does everything well,' he said. 'She just hasn't always had the space to show it.'
Fleur looked at him for a moment with the expression she had at the medic tent — the reassessment. 'You see people,' she said. It was not quite what she had said to Hermione in October, but it was adjacent, and he understood the distinction she was making.
'I pay attention,' he said. 'It's different.'
'Is it?' she said, and moved away, and he thought: she is going to be interesting to know, this year.
He found Krum's partner near the end of the evening — a Durmstrang girl named Ivanova who had the quality of someone who had agreed to something formal and had found it less formal than expected and was not displeased. She had spent most of the later dancing talking to Neville about something botanical — he could see from across the room that Neville was animated in the way he was animated about plants — and she looked at Ron when he approached with the openness of someone whose evening had exceeded expectation.
He asked her to dance because the occasion seemed to call for it and because Krum was watching from the table with the expression of someone who found the question of whether to be amused more interesting than he was letting on.
She danced well. They talked very little, which was the correct amount for two people who had no shared language beyond the conversation of the dance itself. At the end she said something in Bulgarian that her expression suggested was thanks, and he said you're welcome in the five words of Bulgarian he had acquired from Krum across the previous weeks, and she looked at him with genuine surprise and then a laugh.
He walked back to where Hermione was standing with the quality of someone who had been watching the whole thing and had opinions.
He reached for his camera.
He took the photograph.
