1) Obito's Final departure.
I guess Obito is "redeemed" and has a happy afterlife with his dearest Rin.
2) Naruto SEPARATES BZ from Kaguya
So glad to see that Noisy and Annoying thing chopped off.
I hope Sasuke or Kakashi hits him with some Raikiri, and burns him to ashes.
3) Kaguya is not as all powerful as she looked at first.
Her Chakra depletion continues to confound me. The initial portrayal of the Juubi did not seem like a being that could be this depleted in chakra. She was able to draw chakra away from the humans bound to the Chakara Sucking Zetsu Making Tree. Perhaps BZ wanted her to return there?
Next week we'll probably see SO6P use the Hokage's remaining Chakra (except for Minato's) to weave a Jutsu to prevent the tree from taking Chakra out of the dreamers.
One could guess that the Ice World is Kaguya's original dimension and her original purpose was to obtain the Chakra tree's fruit and its power, to use to revive her dimension and her people (In Kishimoto's world, nobody is ever purely evil). It would then seem that once she obtained all that power, she decided to remain and use it to Lord over Naruto's dimension, and to that end she ended all wars and became supreme, and SHE DECIDED TO REMAIN here and be Queen forever, rather than use up the power in restoring her own people. Black Zetsu probably came here with her from the start in some form, and may really have been her son from the home dimension.
