What would a Kenshi and Team 7 interaction look like. Like, would he be an uncle type cuz of Kakashi. Would he meet Team 7 pre-Shippuden, then meet them again when Sai joined and be like, “Sasuke, you look different.” I need to know.

God if Sasuke hadn't made such a show of leaving the village (with Naruto's loud help) that beautiful interaction could have been possible!

I honestly don't know how they would interact though... Kenshi's genins should graduate sometime between team Gai and the 9 rookies. (They're special little kids a.k.a. we couldn't pick a class for them) so they know of them, but maybe don't know them.
