"I know.." He knows that Kurama is capable of helping, but at the same time... why? That's also an easy question if he considers the details, considering that Kurama had already said he piece so far as to why he had come back. He lets Kurama finish up with what he wants to do for his shoulder, feeling numbed but not in the way that would be advantageous when it comes to think kind of injury.

Yes, he would heal up physically in a matter of hours, but the idea of being so exposed as Kurama having the only hirui he has ever made, to his knowledge, now hanging around his neck...

It's worse than any other potentially embarrassing first experience that Kurama had been with him to fumble through. He wouldn't be able to explain why if he tried, but suddenly Hiei very much regrets showing up here when Yukina's energy was not around very much. His response to Kurama is probably not very encouraging, not with the few moments it takes him to, again, realize he's being spoken to, too busy being caught up in his own head about the stone around his neck.

"I'm fine." A lying liar through and through it would seem.

"You -" You have it, he means to say, but then stops, shaking his head. "Nevermind."
