Call it what you want but I wouldn't be surprised if Kakashi trained Boruto again in "filler." While Sasuke trains Sarada instead. Would be funny if both happened in the same episode. The look of your shocked face. If only I could see it.That was false filler praise, since he had to cheat against genin. He only meant him having ninjutsu utilisation. I mean he tunneled under Kakashi without even injuring his finger nails, we know how canon that was.
