He introduced himself the following morning.
Gon was in the same tidal pool, having moved on from bare-hand fishing to attempting to identify what kind of creature had made a specific type of track in the sand at the pool's edge. He was crouched over it with the focused intensity of a scientist who had not yet learned that some questions were not answerable with five-year-old methodology.
Kaito sat nearby and used his Pattern Recognition to identify the track — a small bivalve, from the shell impression and the drag line — and decided to say so.
"Clam," he said. "Small one. It moved at high tide and got stranded when the water went out. It'll be buried somewhere nearby."
Gon looked up. He had dark eyes and the particular quality of full attention — not the polite attention of a child who had been taught to look at people when they spoke, but the genuine attention of someone who was actually interested.
"How do you know?"
"The track shape. The shell impression at the start point, then the drag line." Kaito gestured. "It was pulling itself. Bivalves move like that when they're trying to get back to wet sand."
Gon looked at the track with new interest. Then he started to dig, carefully, at the end of the drag line where it disappeared into the sand. Twelve seconds later he produced a small clam, examined it with delight, and put it back.
"I'm Gon," he said.
"Ren," Kaito said.
And that was that.
The friendship built itself, the way things built themselves when both parties were genuinely interested and neither was performing. Gon was interested in everything — in the clam, in the track, in why Kaito knew about the track, in what other tracks meant what things, in the way fish moved at different times of day, in the names of birds, in the boats, in everything. His curiosity had no hierarchy; he found the clam as interesting as the fishing fleet and the fishing fleet as interesting as the strange shape of a cloud.
Kaito found this restful in a way he had not expected.
His previous life had been organized around the game, which meant around the banner, which meant around the pull session, which meant around the three seconds. Everything else had been infrastructure for that — work was money, money was gems, gems were pulls, pulls were the three seconds. He had been very focused for a very long time and the focus had been pointed at something that did not expand or grow or change how he saw anything.
Gon's attention went everywhere and found something real in every direction, and walking around the island with him was — different. The island was the same island. He had been on it for eight years and had mapped it with the efficiency of someone who processed environments as data. With Gon, it was different data. Gon noticed which rocks were warm on which sides at which times of day and had theories about which fish used that to navigate. Gon had names for specific birds that were entirely of his own invention. Gon had a favorite tree because of the angle of a particular branch and not because it was a useful tree, just because the angle was good.
He found himself noticing things he had not before. Not because his Pattern Recognition had missed them — it hadn't, it catalogued everything — but because the catalogue had not included a category called this is good for no reason except that it is good. Gon had that category and it was very full.
He did not tell Gon about the panel. He did not tell him about his previous life. He did not tell him what he knew about the story.
He did not tell him because none of it would help. Because Gon was five years old and then six and then seven, and he was building something here that was real, and the real thing did not require the backstory. He was Ren. He watched things carefully. He knew a lot about fish and tracks and bird behavior because he had read extensively and had a good memory. He was Gon's friend.
That was enough. That was, in fact, more than enough.
He did, once, tell him obliquely: "The world outside the island is harder than it looks from here."
Gon looked at the sea for a moment. "I know," he said.
"You don't yet," Kaito said. "But you will. And you'll be okay."
Gon looked at him with a slight frown that was, for Gon, deep skepticism. "Are you okay?"
The question surprised him. He had been so focused on managing his own situation — the urge, the exchanges, the aura development, the preparation — that he had not thought about what his behavior looked like from outside.
"I'm working on it," he said.
Gon nodded as if this were a complete and satisfying answer.
Kaito thought about it for a while after, and decided that for Gon, it probably was.
