The train back from King's Cross on the second of January had the quality that return journeys always had — the specific contrast between the place you had been and the place you were going, the particular texture of re-entry into a rhythm that had paused and was now resuming.
On the train back he sat with Harry and Hermione and the two of them passed a book back and forth in the specific configuration of people who had been apart for ten days and had slipped back into proximity with the ease of something that had not stopped.
He took a photograph of them from across the compartment — Harry asleep against the window, Hermione reading with her feet tucked up and the book balanced on her knees — and thought: February. The lake. There is work to do first.
He told them his plan on the first Sunday back.
They were in the Room of Requirements, which had given them the training space they asked for and the additional quality it had when it understood the occasion required something more than the functional. He had been thinking about how to frame this since November — the specific question of how to present what he needed to present honestly without producing in five fourteen-year-olds the kind of existential weight that was counterproductive to the actual work.
He had decided on directness. They had always responded better to directness than to management.
'The training is going to change,' he said. 'From this month we work in two tracks. The first track is what we've been doing — defense, stealth, the specific skills that will be useful for the immediate year. The second track is preparation for something further ahead.'
He let that settle for a moment.
'How much further,' Harry said.
'A year,' Ron said. 'Possibly two. There is going to be a war.' He said it plainly, because the plain version was the only honest one and they were all old enough to be told honest things. 'Not a distant possibility. A certainty, arriving on a specific timeline. What I've been building toward since second year is preparation for that. I am now asking you to prepare for it with me.'
The Room was quiet.
He looked at each of them. Hermione, who had known this in the general shape since the back step at the Burrow in third year and was now receiving it as a specific formal statement. Harry, whose expression had the quality of someone for whom this was not new information but was now being named in a room where naming it changed something. Ginny, who was very still in the way she went still when she was deciding what something meant before she responded to it. Neville, whose expression had done one quick thing and then settled into the specific steady attention he had when he had decided to be present for something difficult. Luna, who was looking at him with the quality she brought to things she had already understood from a different angle and was now receiving the words for.
'What does the second track involve,' Hermione said. Not a question about whether. A question about what.
'Two things,' he said. 'Large-scale offensive spell work — not dueling, but the kind of magic that functions in open field conditions against multiple targets simultaneously. And targeted work: identifying and disabling wards, moving through secured spaces undetected, incapacitating specific individuals quickly and cleanly.' He paused. 'Some of what I'll teach you is designed to hurt people. I want you to understand that before we begin. I will teach you the same way I teach everything — with the full explanation of what it does and why. What you do with it is your decision.'
A beat.
'All of us,' Ginny said. 'Not just Harry.'
'All of you,' Ron confirmed. 'The war does not care about individual importance. It will require everyone who is capable of contributing to contribute.' He looked at her. 'You are all capable.'
Neville said, quietly: 'My parents were Aurors.
'I know,' Ron said.
'Then you know why I'm in,' Neville said, with a simplicity that landed in the room and did not require elaboration.
One by one they confirmed it. Harry with a nod that had the quality of someone accepting the shape of their life. Hermione with the directness of someone who had already decided. Ginny with the specific set of her jaw that meant she had considered and committed. Luna with the mild certainty of someone for whom the decision had been obvious since before she was asked.
'Good,' Ron said. 'We start tomorrow. Tonight, read this.'
He produced six copies of a single sheet — his own handwriting, close and precise — which laid out the first month's curriculum. He had written it over the Christmas break in the Burrow, at the kitchen table after everyone else was asleep, in the specific quiet of a house that trusted him to be doing something useful with the hours.
They took their copies and the session ended and he stayed behind for a moment in the Room after the others had filed out, alone with the specific quality of someone who has said an important thing and is in the first few seconds of having said it.
The Room was quiet around him.
'Alright,' he said, to nothing in particular.
Then he went to dinner.
