They suited up in the dormitory.
Harry had the trunk open on his bed — the specific trunk, the one he had organised since third year with the quality of someone who understood that preparation was the difference between chaos and decision. He took out the basilisk hide. Ron took out his own from the expanded pouch at his belt, where it had been living since he had it made before Egypt in the specific way he kept things he might need without notice.
The hide had a particular quality against the skin — cool initially, then body-warm, the specific weight of something substantial without being restrictive. He put it on in the way he had been putting it on in practice since third year: methodical, without ceremony, each fastening checked twice. The training had made him someone who checked things twice not from anxiety but from the habit of someone who knew what twice cost and what not-checking-twice could cost.
Harry dressed quietly across the room. They did not talk during this. They both had to get into a certain mindset for tonight and talking was not going to help.
When it was done, Harry reached under his bed and brought out the Sword of Gryffindor.
The morning light from the dormitory window caught the rubies in the handle. The blade had the quality it always had, which was the quality of something that had been made to do what it was going to be asked to do tonight. Ron looked at it and thought about the Chamber — about the first time Harry had pulled that Sword from a hat and gone toward something that should have killed him — and thought about the specific distance between that twelve-year-old and the person standing across the dormitory from him now.
Beside the Sword, in the trunk, the Hufflepuff Cup wrapped in cloth, retrieved from the vault by sable. Harry lifted it with the quality of someone handling something they did not want to handle longer than necessary. He put it in the pocket of his robes without ceremony.
Ron checked the goblin-worked knife at his belt — the blade he had prepared in the Chamber the previous October, the basilisk venom worked into the metal in the specific way that goblin steel held what it was imbued with. He did not draw it. He simply confirmed it was where it was.
Then neither of them moved for a moment.
The dormitory had the quality it had in the early morning — the low light, the other beds empty, the particular quiet of a space that had been lived in and was about to be left. He had woken in this room every morning since second year. He had stood at this window. He had thought in this room, and written in this room, and been fifteen in this body in this room, and the accumulation of that — four and a half years of this specific life — was present in it the way places absorbed the people who inhabited them.
He looked at the window.
'I want to say something,' Harry said.
Ron looked at him.
Harry had the expression he had before things that mattered — not frightened, fully present, the quality of someone who had put down everything that was not relevant to the next few hours. But there was something additional in it, something that was not pre-battle preparation but was older than that, the quality of someone who had been carrying something for a long time and had decided this was the moment for it.
'I know what you gave up,' Harry said. 'Coming here. Arriving the way you did. You had a life and you gave it up for this.' He paused. The morning was quiet around them. 'I know you didn't do it for me specifically. But you did it in a world where I exist and you spent five years making sure I survived it. That's — ' He stopped. He found the word. 'That's the kind of thing that doesn't have a proportionate response.'
Ron looked at him.
'So I'm not going to try to have one,' Harry said. 'I'm just going to say: I know. And you coming here mattered.'
Ron held this for a moment..
'You're worth it,' he said. 'That's not sentiment. It's an accurate assessment of what you are.'
Harry's expression did the thing it did when he received something and had decided not to manage it. 'Right,' he said.
'Stay close to Dumbledore in the opening,' Ron said. 'Not because you need protecting. Because I need to know where you are.' He held Harry's eyes. 'When you have the chance — the Cup. Don't wait for a clean moment. There won't be a clean moment.'
'I know,' Harry said.
'After the Cup, everything else becomes possible. Before the Cup, we are managing.' He paused. 'You understand the difference.'
'Yes,' Harry said. 'I do.'
He put the Sword under his arm. He looked at Ron once more with the expression of someone who had said the thing and was satisfied with having said it. Then he picked up his bag.
They went downstairs together, through the portrait hole, into a castle that was still sleeping and did not yet know what the night would hold, and the corridors were empty and the torches were low and the specific quality of a building that had held them both for five years received them one last time in the dark before everything changed.
