Juni should have dealt with those Bullies...

Juni was being harassed at school by a bully whose own father encouraged him to do it right in front of Gregorio who did nothing.

I would have liked to see the two of them return to the school in the epilogue and dealt with them.

Someone said that Disney was trying to convey that fighting with bullies only stoops you to their level. But I say that if you don't nip a problem in the bud it will continue to grow.

So a compromise should have been that Greg and his son return to the school and Greg says to Juni; "OK son, do what you have to but no more than that."

Juni confronts the bully, tells him to knock it off from now on and when the bully throws a punch, Juni grabs him and pins him to the ground and doesn't let him up until he says 'Uncle'.

Then when the father tries to step in (typical of types like that), Greg confronts HIM and says; "Hold it, you! If you're going to teach your son to be a bully, he's going to have to learn the final lesson all bullies learn...that sooner or later you're going to have to fight fair."
Then when the father takes swing at Greg he pins him too and makes him say 'Uncle'.
