What happened to the 6th sixth zetsu? MILLION DOLLAR QUESTION

[Darklor]

Orochimaru brought six zetsu's from sasuke's body
but he used 4 zetsus to revive the Hokages
He used one to occupy his body
Then that leaves out only one zetsu remaining
what happened to that 6th zetsu?

He will probably experiment with him, get more DNA.

Juugo absorbed it, this is like the millionth post of this...

Jugo took it into himself... Though I'm sure it'll be used later on.

Why even make it six if you weren't gonna use one? Kishi might be hinting at something...
