Good thread. That really is possible, it does seem like it's Kishi's style. *********** also says they need to put their seals together so I guess we will have to wait for Viz. I hope it does happen that way. I think Naruto will try to start the fight off with this because no one really knows how long it takes for people in IT to turn into White Zetsus, and I'm sure he wants to get them out of IT as quickly as possible.
He knows now that Sasuke will not free them voluntarily so he will have to trick him into it. As arrogant as Sasuke is he is probably thinking that he can release everyone from IT when he wants with his rinnegan. That might be possible if he had 2 rinnegan but I'm thinking that the sage only gave each of them half of the power to revive everyone so they would have to work together after the sealing of Kaguya.
Naruto seems very confident that he can get this done so it seems that he has a plan already. Naruto does not look nearly as surprised as everyone else so I think he was expecting Sasuke to pull something. It is Naruto's nature to mostly trust people but I think he has been in trust but verify mode with Sasuke since Sasuke came to the battlefield. I think he long passed the point of trust even as he was glad to have Sasuke's help.
He didn't like when Sasuke tried to burn the tailed beasts inside the 10 tails, he was annoyed when Sasuke only tried to save him and Jugo, he was angry that he was willing to let Sakura, Kakashi and Obito die in the lava dimension and he didn't like how Sasuke has been disrespecting Kakashi and Sakura by treating them as useless. I think he knew this might be coming and is prepared for it.
Everyone likes to say how naive and stupid he is but he is much better at battle strategy than people give him credit for. I don't think he was fooled by Sasuke's behavior and his playing down of his abilities and I think Naruto too did not give away too much of his abilities. He instinctively knew he could help Guy. Their powers didn't come with instructions. I think Naruto's instincts are much sharper than Sasuke's because of his training as a Sage and because of all of the work he had to do to overcome his hatred and get along with Kurama.
