Kurama knew what he was willing to go through to prove himself to Hiei, the trick was determining how tolerant the fire demon would be of his efforts. That accidental slip of the hirui had clearly shaken them both up, revealing more than either had truly intended, and he needed some time to regroup emotionally before returning. He'd be surprised to know the fire apparition wasn't expecting him to come back at all, as he’d said he was going to get supplies to help, but perhaps he expected the realization of what Hiei had been reacting to, to change his mind on that front.

Once he was back, the fox sets to the task, doing as much as he can around the makeshift sling before having to remove it as he cleans and dresses the wound more appropriately - working in uncharacteristic silence after that initial explanation - while replacing the poultice with something up to his own standards, instead.

He'd even brought an actual sling from the temple's medical supplies. An extra measure in an establishment where most of the residents could set bones with their energy, Botan and Kurama both particularly mindful of the more mundane health care options for emergencies when advising on how to keep things stocked as a precaution.
