The White Zetsu's application contained just one statement.
"I haven't attacked again, and I haven't responded to Zetsu."
"Why can't I leave yet?"
Temporary isolation had initially been established to prevent possession by Black Zetsu.
Black Zetsu had already been placed in dispersed sealed storage.
The possession layer had also been severed.
The original direct danger had declined substantially.
But isolation did not automatically remain justified simply because the enemy had been captured.
Likewise, Black Zetsu's inability to possess this White Zetsu did not mean they posed no other risks.
Their body still came from the old network.
It might retain connections to the Lunar Surface and the Demonic Statue, as well as dormant orders.
The Five Nations had no existing identity category that could be applied.
They were not an ordinary prisoner of war.
There was no complete record of their participation in the war.
Nor could they immediately obtain resident status in some Shinobi Village simply by demonstrating sustained response.
Someone proposed tracing the original source of the White Zetsu's body.
If they had been transformed from a human in the past, their original identity and national affiliation might still be valid.
But the available material consisted only of incomplete God Tree records.
Forcibly reading their origins from their body would violate the memory boundaries that had just been established.

The hearing therefore did not prematurely declare them to be some missing person, nor did it classify them as an inherently stateless object.
The investigation into their origins could continue.
Their current eligibility to act would still be handled according to the consciousness and risks that could presently be verified.
The first verification remained memory.
The White Zetsu could recount the Three Withered Roots, Black Zetsu's possession,
