[ Iruka is far from fine and Kakashi knows it, but arguing with a delirious man would be a rather ridiculous waste of his time. Explaining Luceti to him, as well as the situation they're in, would be pointless as well, as Kakashi's not entirely sure how coherent Iruka's thoughts are, or how able he is to process information.

At the very least, Kakashi needs to keep Iruka awake until Sakura arrives.

Perhaps if he engages him on this "hobo" topic which Iruka seems to have latched onto in his current state, that would be enough to keep his attention. ]

Are you saying bums can't be normal, too?

[ Somewhat deadpanned. He kind of can't believe he's actually continuing in this line of conversation, but it's not as though he can really talk about anything serious with Iruka while he's still like this ]
