You’re allowed to rewrite a single character and arc. What would you choose?

For me, I’d rewrite Tenten to make her more of a scroll + seals master, goal of collecting the 7 swordsmen weapons and to learn + teach Naruto the FTG.

For arc, before Sasuke and Itachi meet again, I’d want a mini mission arc for team 7, to show their bond just one more time :(
