Kurogane didn't take Fai's next words as a change of subject at all. Tamaki had already said earlier that Fai needed to be kept warm for some reason, so him saying that he was cold wasn't a good thing. There wasn't much he could do for it though, Fai had already been surrounded with blankets, and there were not any others on hand.

He knelt down a moment to see if any might have been under the bed but only found the metal stick he'd released earlier laying there. Right, he'd let that go, hadn't he? Grabbing it again, he came back up and looked back at the boy.

"Kurogane," he corrected when Mello (that was a name?) only got it partially correct. Of course, Fai was to blame for that, but he was to blame for a lot of things. "And he's Fai," he added, even though Mello had asked Fai himself. He still didn't trust the magician's words to be completely accurate; he wasn't even answering the questions posed. "He likely did fall, from the second floor into the Sun Room," he explained what he'd been told, "but I doubt it was because he was careless." Idiotic, perhaps, but not careless. Carelessness didn't explain a good majority of his injuries. His legs wouldn't be so bad from just a mere fall either.

He would have continued explaining when Fai said something familiar: Ashura. The same name that had paled Fai back in Shura. Kurogane's eyes hardened down at Fai, even though the other wasn't facing his way any longer. That he'd actually given that name... maybe this delusional state was better for questioning the man. It wasn't like Fai to give away anything when he was thinking clearly, so having him when he wasn't thinking clearly might just be what Kurogane needed to learn some things.

"What about Ashura?" he asked directly, determined not to pass up the chance.
