Black Zetsu's sole mission from the moment he was born was to free Kaguya Otsutsuki from the Sage of Six Paths' seal, reuniting mother and son(?) at last.
This was not resurrection, but it was as good as resurrection.
But Black Zetsu's reason returned just in time, and he forcibly swallowed the two words that had almost left his mouth.
