Well, Obito's story gets more and more interesting...
More reasoning as to why he can't leave.
Zetsu gets a bit fleshed out (heh...)
Spiral Zetsu and white Zetsu? How many are there?
Finally his hair looks like Madara's.
And Spiral Zetsu looks like his mask, and when he wears him, looks like Tobi. I think we see where this is heading...
