[ Sasuke had trained with a kind of hunger rarely ever seen in children. A sort of desperation that cut his hands right open, flaying the skin off with lightning almost down to the bone. Maybe he thought if he trained harder, longer, it would somehow bring him closer to his intended goal of avenging his family. Kakashi could only hope Sasuke would come to learn that such techniques could be used to protect, instead of destroy.

(He was wrong.)

Kakashi's gaze tracks for a moment to Sasuke's hands, before flicking back up to the boy's face. ]

I wouldn't expect anything less. Though, with our chakra reserves halved, you'll want to be careful.

[ He's sure Sasuke will just scoff and roll his eyes at the gentle admonition, for telling him things he already knows quite well. But says it anyway.

Maybe Kakashi was a failure of a teacher, but that doesn't mean he can't still try, somehow, to make up for that. ]
