The photographs arrived on the twenty-seventh.
By owl but not his owl— Mira was at the Burrow, perched on the back of the garden chair she had claimed as her own in August and which no one had formally agreed to give her but which was now simply hers.
The photographs came by a different owl entirely — small, quick, slightly self-important in the way of a bird that had been given an important delivery and knew it.
He recognized the older elf's planning in the delivery. She had arranged it. Of course she had arranged it.
The package was wrapped in plain cloth, tied with kitchen twine. He opened it at the kitchen table, which at half past nine on the twenty-seventh had his mother on one side of it with tea, his father across from him with the Prophet open to the Ministry section, and Ginny at the end with the Japanese cookbook he had brought home and which she had apparently been working through since the twenty-fourth with the focused attention of someone who had decided a thing was interesting and was doing something about it.
Inside the cloth: twelve photographs.
He looked at the first one and made a sound that was involuntary and that his mother looked up at.
The photograph showed the Great Hall during the Christmas feast — the enchanted ceiling doing its winter thing, the house tables arranged in their traditional configuration, the staff table at the far end with the specific warm chaos of a feast in full progress. This was all as expected.
What was not as expected — what was, he had to concede, even better than he had anticipated — was the suits of armour.
They had, he was clear, committed entirely. The choral arrangement had activated and the suits had not merely stood in their places and produced sound. They had found, somewhere in two centuries of dormant enchantment, what could only be described as performance instinct. The suit on the Entrance Hall staircase — which he had designated as first voice — had its visor tilted at an angle that suggested it was aware of its own leading role. The suits on the second floor landing were arranged in a rough semicircle. The suit on the third floor landing had, as he had feared, encountered the ceiling clearance problem on the leaping lords and had resolved this by leaning sideways in a way that was technically within its spatial parameters and technically looked exactly like a suit of armour that had been interrupted mid-leap and was being dignified about it.
The photographs were moving, in the way of wizarding photographs. He could see, in the third image, the moment the armour reached the verse about the five golden rings — the suits had apparently decided, collectively, that the rings warranted a pause, a breath, and then a volume increase that the photograph communicated through the slight flinching of everyone in the foreground who had not been prepared for it.
In the fifth photograph: McGonagall.
McGonagall's expression in the fifth photograph was one he had never seen on her face in the months he had been watching it. It was not the controlled warmth she produced for students who had done something well. It was not the exasperated disbelief she reserved for things involving the trio. It was something older and more personal — the expression of someone who had been in this castle for a very long time and had just watched it do something she had not known it could still do, and who was allowing herself, in this specific unguarded moment, to be delighted by it.
He looked at that photograph for a long time.
"Ron," his mother said.
He passed her the first photograph. She looked at it. Then at him. Then at the photograph again.
"The suits of armour," she said.
"Yes," he said.
She looked at the performing armour in the moving photograph — the visor tilted at its self-important angle, the semicircle of second-floor suits, the third-floor suit leaning with dignity into its geometric constraints.
"The Twelve Days of Christmas," she said.
"All twelve verses," he confirmed.
She put the photograph down on the table with the careful precision she used for things she was going to need to look at again later, and picked up her tea, and said nothing further, which was her version of I have decided to be entirely unbothered by this and am implementing that decision immediately.
His father, who had looked up from the Prophet during this exchange, picked up the photograph his mother had set down. He looked at it for a moment. His expression did the thing it did when he felt something large and kept it entirely internal.
"The activation sequence," he said, to no one in particular. "I've read about that. The 1743 Hogwarts charter amendment. I didn't know anyone had ever actually used it."
"It worked very well," Ron said.
His father looked at him with the expression of a man who had been a civil servant for twenty years and had developed very reliable instincts about what he was looking at. He said nothing.
Ginny had abandoned the Japanese cookbook and was looking at the photographs that Ron had spread across the table. She had found the third-floor suit in the leaping lords photograph and was looking at it with the specific focused expression she brought to things she found genuinely funny and was managing with dignity.
"The ceiling," she said.
"I know," he said.
"It's doing its best," she said.
"It really is," he said.
She looked at him. Her expression had the quality it had been arriving at since Egypt — the one that was simply itself, without the careful bracing beneath it.
"You're ridiculous," she said, with great warmth.
"The Witness is ridiculous," he said. "I'm just a bystander."
She made a sound that was a laugh converted, at the last moment, into something smaller, and went back to looking at the photographs.
The last photograph in the stack was not from the feast.
It was from after — the Great Hall empty, the armour back in their places, the notice boards. A single card on the Gryffindor common room board, cream-coloured, the unfamiliar hand, the golden eye with the line he mentioned.
And behind this last photograph, an addition from the elves
Happy Christmas. The castle remembers.
He looked at it for a moment.
Then he put it with the others in the inside pocket of his jacket, alongside the photograph of his parents at the Hogsmeade gate and the one of the Nile in the Egyptian evening, and went to help Ginny with the Japanese cookbook, because she had found the section on dashi and had a question about the kombu that he could actually answer.
