yeah but he wouldve been shown either way with obito or with the mozou or tree with the hashi clone in itVery suspicious. Many Jutsus went unexplained and the markings were suppose to hold what purpose exactly?
How unfortunate, you should work on that.
I did read somewhere on a translation of swirl zetsu's profile that he can't survive without harboring somebodies body or something about "Gedo mazou's light."
So he didn't have the liberty of going wherever he wanted like White Zetsu and Black Zetsu did.
