Well, Chapter 444 is awesome, and yet, disspointing at the same time. We already knew Nagato lost his parents to Kohona ninja, and the fact that they were in shock, and apolgised makes all sympathy go away for little Nagato. We still didn't see how the Rinnegan killed them, or, find out Naruto's answer.
Although, we seem to have yet more evidence of Kakashi being DEAD, as Naruto thought of him in the same light as J-Man, a dead teacher, by Nagato's hands.
We now know Nagato's death is almost cirtain, as Naruto said 'No matter what, I can't forgive you', but he wants to know how such a monster was formed. The fact that Nagato tried such a underhanded attack made Naruto madder, and he needed the Kuyybi's Chakra to heal, hence, Sage-Kuyybi, and pure awesomeness. We need to find out it's powers, and what the significance of it is. Especially seeing as there is now a different type of chakra in the delecate balance, the massive amounts of the Kuyybi's chakra.
Still, I think in 445, we'll see the end of that story (Unless that is the end of it, we don't see the killings), and the second event will either be the death of Yakido, or, the event which caused the J-Man to see the Rinnegan, as the death of his parents was before he met the J-Man. Then, part 446 would be Naruto's answer, and quite possibly Nagato's death, or if Konan's allegied reason for joning was true (love), Konan will defend Nagato, and a fight/discussion will start between them, over how she can defend a monster like him. If a discussion does happen, we'll likly find out about Konan, and more of Nagato. I just don't see Konan letting Nagato be killed, unless he demands it from Natuto, or kills himself.
