Everyone seems to be aware of his true intentions. We don't know exactly what is it but the closest we ever got is when he tried to burn Juubi into ashes along with all other bijuus. Hashirama picked up a bad vibe as well. Tobirama best described him as another Madara, which I wouldn't take that compliment unless said otherwise. If anything, Hagoromo probably is the only one that got the answer and the best way to describe it is regret as in things never changed. With Naruto, it's a new hope.You know, I always think that Naruto is well aware of Sasuke's plan. I mean whenever the topic of Sasuke's goals or motives comes up Naruto has to have a weird reaction. Even in the latest chapter, his expressions were like, he detected something or something just striked him and then he said "He should not cross the dimension". Now this could either point to a threat Obito and Sakura have from crossing the dimensions OR it is pointing towards Sasuke meaning he is upto no good! Even if this is wrong, then too I really find it peculiar that Naruto has to have some weird reactions or just divert the topic when an issue of Sasuke's goals comes up. I really think he is aware of his goals!
That said this is why I'm very focus on this because what kind of climax should I expect from Sasuke's secret plan. In fact, what should I expect from Sakura in her road of downfall with Sasuke? If this event even connects to that? I think that last one I said is what I'm truly concern. It doesn't help that this chapter had to mix in with Naruto being the energy for them.
