Most demons with the skill and power to last over a thousand years wouldn't take too kindly to being lectured by one who had barely passed decades, but most other demons weren't Kurama.

He doesn't comment on Hiei’s next retort, the fire apparition might never admit it but he's worried and there was no point in shoving his face in it by dragging this conversation out. He said his part, made his point, and the fox seems bordering on amused rather than the least bit offended.

Really, it was Yusuke who seemed the most concerned about all of them.

Kurama hums at Hiei's decision, also happy to change the subject, but unable to hide the faint smirk with those words.

“Far be it for me to deny you the opportunity. Although, I seem to recall Yusuke being the team leader. Unfortunately, I believe that puts him in charge of those decisions.”

Did he think Yusuke was going to stop Hiei if it came to that? Not likely, but teasing had a way of distancing them from the tension of particularly heavy topics and it wasn't beyond him to use it to do so, given the opportunity.

The fire apparition being mad that a teenage human dictated their actions at the moment was better than Hiei worrying about the fox's welfare, at least.
