I think it will be revealed that kawakii is from the jugo clan it can explain why there dad and him lived in a remote area and why he abused him due to their clans uncontrollable rage.
Might ask why hasnt kawakii exhibited this rage yet amado might of figured how to remove it.
I also see him being enhanced with naruto and sasukes DNA having high chakra reserves with the sharingan.
We know amado can genetically enhance and kawakiis hair does suggest he will be a hybrid.
And seeing the part 1 vote fight looking alot like the original.
