Finally! It's back! Please let it be for good this time!
So there's somebody inside Spiral Zetsu, and I'm betting it's Yamato. He's probably not even conscious, but I bet Spiral Zetsu is using his body to amplify it's Wood Styles.
This episode kind of made me feel like the entire portion of the arc where Obito was the 10-Tails Jinchuuriki was just a big waste of time. All that effort going into defeating him and getting it out of him, just for Madara to immediately take it back and do the same transformation.
That whoooooole part could have just been skipped and they could have just made Madara the Jinchuuriki in the first place and saved us a ton of time.
I have a sneaking suspicion that Madara just stupidly set up his own downfall by just throwing away the Sage of the Six Path's Treasured Tools. After all, they're the tools the SotSP used to bind the Ten Tails in the first place. I doubt Kishi would have bothered to have him cough them up if he didn't intend for someone to use them against Madara later.
And worse, he just happened to drop them on Ten Ten, who's the only person who already used one of the Tools, and probably knows where the last one is.
Betting that the Tools actually do something awesome if you bring all 5 of them together.
Definitely agree that it was super dumb that the good guys were so oblivious as to let Zetsu take the other half of Kurama.
But Madara just throwing away the tools is just as dumb, so I guess it evens out. Everyone is being extra dumb to advance the plot.
