Re: Hidan Not Immortal?
Exactly, he wasn't a sage in the latest episode. He looked rather young. Although it's a filler a lot of this were weird about this episode. He summoned all the Akatski Edos, besides Nagato I believe, but wasn't in SM, so this had to be before he threatened Tobi for an alliance? Assuming he wouldn't go up against Tobi without full control of his edo summons. And this means Naruto doesn't have SM either as he learned it before going up against Nagato.

EDIT: Review the episode, Nagato does get revived. They probably don't move on the account that he is not a sage yet, which gives him a needed chakra boost. Still I find this whole episode odd, the side story is weird and almost pointless. But I enjoyed all of it though, pretty unique.
