His father drove up in early August with a folded list of questions in his breast pocket and a medical bag in the back seat that contained, along with standard supplies, several items he had clearly decided were relevant to a camp full of demigods and was not going to be talked out of bringing.
Chiron met him at the gate. Kael had watched this from a distance first — wanting to see the meeting without being in it, to understand the shape of it before he joined. What he saw: two men of profound competence in completely different traditions regarding each other with the careful respect of people who can recognize quality in an unfamiliar form.
He went down the hill.
His father hugged him with the particular warmth of someone who has been worried in a managed way for several weeks and is relieved to have the worry addressed by physical evidence. 'You look good,' Marcus said. 'You look like you've been outside a lot.'
'I live outside a lot,' Kael said.
'The staff.' His father looked at it, leaning against Kael's hip. 'It suits you. I don't know why I say that — I don't know anything about staffs — but it does.'
He gave his father the tour. Not the official one — Chiron had already done that. The real one: the eastern woods where he practiced, the healing room where he and Will worked, the library where he and Annabeth spent afternoons, Thalia's Pine at dusk. He brought him to the Apollo cabin and introduced him to Will Solace, who shook Marcus's hand and said, without irony, 'I've heard a lot about you. Kael says you're the reason he understands medicine the right way.'
Marcus looked at his son. Kael thought: I did say that. It is true.
The main purpose of the visit was a meeting with Chiron about demigod medical training. His father had spent three months preparing for it — he had read everything Kael had sent him about the healing room's current protocols, had consulted with physician colleagues about wilderness medicine and trauma care, had put together a detailed proposal for standardized first-response training that could be implemented at camp within a single season.
The meeting lasted two hours. Kael sat in for the first forty minutes and then excused himself because he could see that his presence was making both his father and Chiron perform slightly, and they would do better work without him there.
He sat outside the Big House in the August afternoon and thought about his father. About what Jason Park's father had been — distant, busy, present at the surface of things and unavailable at the depth — and about what Marcus Alexander was. He had driven four hundred miles to a camp full of demigods, with a proposal in his briefcase, because his son had said the medical training here was inconsistent and lives were at risk.
He thought: I am the luckiest person in two worlds. He thought this with the full weight of meaning it.
The meeting produced a formal training program, implemented the following spring, which reduced serious training injuries at camp by thirty-one percent in its first year. Chiron wrote to Marcus with the data. Marcus framed the letter.
