They were like, "Fighting is forbidden in Ninja Academy."
Remember that time, like, two episodes ago... that Boruto fought that kid that kept getting held back?
Then, during the flag capturing thing, they are over here throwing Ninjutsu at one another, and ChoCho even knocks a motherfucker out. I guess that didn't count as fighting though? Okay.
I also explicitly remember, because Naruto and Sasuke's love was so strong, that they had to fill every encounter they had after the timeskip with flashbacks, that they were part of a sparring match that was held during the Academy and overseen by Iruka. With the whole, seal of reconciliation. I guess that's not a thing anymore?
My hope keeps going on though. I dropped hopes for some things, but my new hope is that once they get out of the academy, things will pick up some. All this "character" building is pretty awful, abusing cliches and putting the things everyone wants in the background. It's apparent that Kishimoto is uninvolved. I wish he would get involved though... even Toriyama started to get ashamed of Super, so maybe one day Kishimoto will be like, "ENOUGH! I got this."
