Jin was frantic. He had no idea where Touya could possibly be. The people who ran the hotel were already gone; apparently they were open only during the Dark Tournament. The point being, Jin couldn't ask them anything about Touya. No one else was left on the island.
He could barely think; he beat himself so much over what he did, that nothing seemed to click. After a week turning the island upside down looking for anything besides those two scraps of Touya's ki and his shoe, he realized if he was going to be successful he needed to stop and think a little.
He jumped into the ocean and swam for 15 minutes or so, icy water, so much like Touya's cold hands, caressing him and beating him at once. Jin flew out, drenched and dripping, and sat down on the rocky shoreline. Finally he remembered that since Touya couldn't fly, the only way he could have left the island was the ferry.
He then left to find the captain, and was successful.
"Was ther' a short, 'uman-looking youkai with blue an' green 'air on board? He's short an' quiet, an' he woulda' been wearing a white toga thing, a blue tank, an' a grayish netted undershirt?" Jin asked.
"Yes, there might have been," was the captain's uncaring reply.
"Was he with anyone?" was the next question.
"I think so," apathy was apparent, and it angered Jin.
"Look, chikousho, I'm in no mood, an' if ya dun' care tha's fine, but ya 'ad better act like ya do! Now 'ho was he with?"
"I don't know who they were! There were four with him I think, one was short and wore a black cloak. Another was real tall and wore a blue uniform and had bright orange hair. The third was a pale redhead that wore Chinese-looking clothing. The last seemed to be the leader and he was average height for a ningen and had black hair and a green uniform! And they all appeared humanoid but all had enormous ki or youki!" said the captain, worried now. He had just recognized Jin as a Shinobi from the tournament and was scared shitless.
Jin blinked. "Tell me a li'l more abou' the leader." He said, a little calmer.
"I think he had brown eyes and he was a careless, cocky little bastard. Wait, I think he's the one you fought in the Dark Tournament! Urameshi Yusuke, that's right, I'm sure of it! And the one you first wanted to know about, he was clinging to Urameshi like ravens to death!" The captain was panicking, but Jin wasn't going to do anything to him now.
Jin walked a few steps off then flew away, wondering how to find Urameshi Yusuke. He couldn't help but feel further the hurt already instilled in him- the captain had said that Touya had been clinging to Yusuke. Did that mean?....
