This is Shisui, blinking as he tries to wrap his mind around the 'clan' part. How long ago was it since they'd grown out of the system of clans? He'd heard his grandparents talk about their family history once upon a time, but he'd never really given it too much thought. Either this guy was telling the truth about mixing up timelines (if that was even possible), or he was a really good actor. "Right. Spar. Only during training." As it was, he was on a very important mission at the moment, and there clearly was no time for play-fighting.

...He just needs to figure out where he is first in order to get back to whatever was left of his mission.

What makes him grit his teeth and press the edge of the blade further against the other's skin, however, was the fact that something weird was going on with regards to this whole healing thing. He didn't want to admit it, but it almost felt like magic-- and Shisui knew that magic wasn't real. There was always logic behind hocus pocus. Which is why he was already getting to his feet and attempting to put some distance between them, knife drawn and at the ready.

His hearing had vaguely improved, though, and he managed to catch the word 'Hokage', which makes him wince in confusion. "Yeah okay, I have no idea what you just said or what a Hokage is supposed to be-- and frankly? I don't care. Just-- Who are you and what the hell do you want with me?" A beat. "And do you happen to have anything... alcoholic but also consumable... maybe?" Hm.
