Kurama is, for the most part, waiting this out. Trying to get a decent read on the situation before attempting anything riskier than the current back and forth about food. He is, of course, worried about the fire apparition's lack of appetite, but as long as he could keep them on that topic the better equipped he is to work out the next step.

Hiei, of all people, should be aware how much illness makes others worry, but he - like every member of their dysfunctional little group - remains terminally incapable of applying that sentiment to himself.

“Broth might be an idea. Okayu, maybe. This is your first time being sick, we certainly don't want to overdo it.” Logically, Hiei shouldn't be sick in any way that might prevent eating, but standard logic hardly seemed to apply to whatever his body was going through at the moment. Best to proceed with caution.

“If you're going to be up and about, perhaps a different tea to go with it. Your fever seems to have broken, at least. You could try something that wasn't harvested from the depths of demon world with dinner, if you'd rather.”
