She came out of the east wing with her brother. Nico was talking — rapidly, animatedly, about something that had his full attention and approximately none of hers because she was monitoring the corridor with the specific watchfulness of someone who had spent their whole life in a place where not-fitting meant something needed to be managed. She was fourteen, tall for her age, with dark eyes that had the particular quality of Hades's bloodline in them — the depth of it, the sense of seeing past the surface of things.
Kael stood up from the bench as they passed. Not suddenly. He stood the way you stand when you are going to speak to someone and want to be seen clearly before you begin, no sudden movements, no approach from behind.
'Bianca di Angelo,' he said.
She stopped. The name-recognition sharpened her immediately — not alarm exactly, but the heightened readiness of someone accustomed to their name being known by people who should not know it. Nico stopped beside her, looking at Kael with the direct, unguarded curiosity of a ten-year-old who had not yet learned to be guarded.
He gave her two seconds to assess him and not find a threat. He had dressed deliberately — camp colors but nothing aggressive, no weapons visible, the staff folded to compact form in the bag over his shoulder. He looked, he hoped, like what he was: someone who had come a long way specifically to talk to her.
'I'm Kael Alexander,' he said. 'I'm from Camp Half-Blood. I have a Chiron authorization if you want to see it.' He took it out and held it toward her. 'I know Grover is here. I know more is coming. I'm not here for any of that — I'm here because there is a specific piece of information you need and I need to make sure you have it before things get complicated.'
She took the authorization and read it. Her eyes were fast and careful. She handed it back. 'What information?'
Direct. Good. He had hoped she would be direct. He took the envelope from his jacket pocket and held it out to her. 'Read this,' he said. 'You don't have to believe it now. You don't have to act on it now. Just read it and keep it. When the time comes — and you'll know when the time comes — use it.'
She took the envelope with the wariness of someone accepting a gift from a stranger at a crossroads, which was, he supposed, precisely what this was.
'How do you know my name?' she asked.
'I know things about events before they happen,' he said. 'I know this is unusual and alarming. I know you have no reason to trust it. The information in the envelope is specific and verifiable — you'll know whether it's true when you're in the position to use it.' He looked at her steadily. 'What's coming tonight — I can't stop that. I'm not here to stop it. But you are going to end up on a quest. And there is a moment on that quest where you are going to make a choice that will require this information to go right. I needed you to have it before that moment.'
Nico was looking at him with his big dark eyes. 'Are you a prophet?' he asked.
'Not exactly,' Kael said. He looked at the boy — ten years old, the specific brightness of Hades's bloodline in him, not frightened but enormously curious, the curiosity of someone for whom the strange was always interesting rather than threatening. 'I'm from camp. Your power is extraordinary, Nico. Whatever they tell you about it — hold on to the fact that it's yours.'
Nico blinked. Bianca's expression shifted — something in her that had been evaluating relaxed, fractionally. He had spoken to the boy rather than using him as leverage, and she had noticed.
'Okay,' she said. She put the envelope in her jacket pocket. 'I don't know if I believe you.'
'You don't have to believe me yet,' he said. 'Keep the note. That's all I'm asking.' He stepped back, giving her room. 'I'll be at the camp at the eastern edge of the grounds if anything happens tonight and you need someone. Theron — the satyr you might have noticed around school — can reach me.'
She looked at him for a long moment with those Underworld eyes. Then she took Nico's hand and walked on down the corridor.
He sat back down on the bench. He breathed.
He thought: done. Nine years. She has the note.
He thought: now we wait and see.
