Hiei pretends that he doesn't see Kurama texting - he knows what he's doing and who he's checking in with, after all. He could've checked in with her himself if he wasn't so resistant to having a cell phone or anything else that others may reach him on in the first place. At any rate, here and now was not the time to fuss about Yukina worrying about him when he has dealt with far worse than being ill, or injured, all on his own well before now. Beyond that it will get them absolutely no where, he's sure.

Particularly when Yukina is involved. She will hear none of it from him, particularly after all of these years spent getting closer and knowing one another better. Through all of their trials and stone walling bickering, the twins were extremely good at fighting like siblings, these days.

"You think I need to be even further out of my mind, right now?" Forgive him if he sounds even slightly amused right now, Kurama, thinking of putting himself in to a worse state than he is currently. The quiet buzz of even this low-level ability to not think of everything going wrong in the moment is quite enough.
