I think it would have been a LOT cooler if instead of the sand trio coming to save the day it was:
>Ino saving Shikamaru
>Hinata saving Kiba
>Tenten saving Lee
It would be a great opportunity for them to show that indeed they are just as strong if not stronger than the boys.

>Former enemies come back to help the heroes
Name a more kino trope, I dare you.
