Annabeth found him first.
She came out of the Empire State Building at six o'clock in the evening with the specific quality of someone who has been through something enormous and has already begun processing it with characteristic speed. She walked through the lobby doors and looked around the street and found him at the corner where he had been sitting since the battle ended, and she walked over and sat down next to him on the curb without ceremony.
She had been crying. Not currently — currently she was beyond crying, in the territory past it where you have processed enough that the active emotion has given way to something more settled. But the evidence was there.
He did not ask immediately. He sat with her for a minute and let her sit.
Then: 'Luke,' he said. Not a question.
'He came back,' she said. 'At the end.' A pause that had everything in it. 'He asked Percy for a knife. To stop the possession himself. He—' She stopped. Her voice did not break; she was past the place where voices broke about this. 'He died. But he died as himself. Not as Kronos.'
He sat very still.
He thought about the Bethesda Fountain in April. Six sentences in a letter from someone who had been thinking about the wrong distinction for three years. The Central Park bench. I think I made the wrong distinction.
He thought: he found it. The other side of the distinction. He found his way back to himself at the end, and he died as himself, and that is both terrible and the best possible version of a thing that was always going to cost someone something.
'I told him,' he said. 'When he came back in the spring. That whatever he did with the knowledge — the recognition that he'd made the wrong choice — it mattered. That it would always matter.'
Annabeth looked at him. 'He knew you meant it,' she said. 'He told me, after the battle, that you were the only person at camp he trusted to tell him the truth about his anger without either dismissing it or exploiting it.' She paused. 'You gave him something to come back to. Even if the coming back was—'
'Was what it was,' he said. He said it with the full weight of knowing what it was. Not softened. Not managed. 'I know. I'm glad he came back. I'm glad he died as himself. I'm sad he's gone. Those are all true at the same time.'
'Yes,' Annabeth said. 'That's exactly it.'
They sat on the curb in the evening Manhattan and held the weight of the day, together, the way people hold very large things better when there are two people under them.
After a while she said: 'Percy's still up there. Olympus. They're having — some kind of meeting. He'll be down in a few hours.'
'I know,' Kael said. He thought about the note in his jacket pocket. 'I'll be here.'
