lmaoAccepting each other as equals and come in to a solution to end the conflicts .
or sasuke will win but give in to naruto's idealsThe fight will be either a draw or Naruto wins(Sasuke won their first battle so its only fitting for the child of prophecy to win this time) but in the end they will both live, because the cycle will just continue is one or both are killed and together they will help create peace.
imo indra can be rencarnated from hyuga just like senju and uzumaki relevant caseWell after Sasuke all the Uchiha are gonna be dead, so Indra cannot be reincarnated
