Kakashi always found lying on his back fixed chakra exhaustion right up, but she seemed happy enough just sitting down, so he didn't press any further. He wasn't self conscious about his small chakra reserves, as his father had given him disciplined instructions on how to build up his chakra and increase his chakra control - things that her class of academy kids wouldn't learn for quite some time... Although he knew medic-nin required control much earlier than most.. Perhaps that could be something they could work on together.

He shook that strange thought free - why would she want to train with the odd one out in class, after all - and looked at the little bottle suddenly in his grasp.

"That's true, but this isn't a battle and my life wasn't in danger.." he said, giving her a lazy look from under his headband.
