Tsunads and AY were somwhere in the last chapters together! In the IT one, in someone's dream I am certain of it! I think it's Mei.
Plus, the one Mei marries there looks a bit like Kishi's design for Gaara... Something is up!
That was a rumor from someone who was trolling, that was debunked.
We have heard from Evil that Tsunde makes Naruto an arm with Hashirama's cells :)
Because Sakura is of course cleaning up Sasuke's kitten and Kishi couldnt bother letting her make the arm..............
