Well we now know from this chapter that tobi can't be the sage of the six paths because he doesn't know what names Naruto is talking about. But it did hint to that tobi does know something about Naruto's past from the page where he talks about past, present, and future are irrelevant so Naruto's past doesn't matter in this fight. But he is getting really worried because of Naruto's strength and whatever he feels is different about Naruto. I want to know what is actually going on with Naruto, I feel like there is something hidden in the importance of him learning their names, and that he might be related to the SO6P. I'm expecting to see some new form/ jutsu/ power comiing from Naruto soon.
