I'd talk to him on how does he keep his cool and super awesomeness. Moreso, I'd have a very sensible conversation with him regarding his POVs, 1000 copied jutsus, etc.
In addition, I would prolly ask him how it feels to die [and live again].
But best of all, I'd love to should he train me (hoping that those jutsus really exist in real-world, which is nothing but a dream) how to tactically strategize, zero in opponent's move and ability and of course perform arse-kicking jutsus of all nature types!
