This is true. They still have some connection to the tree and can travel anywhere. Then there are the tools/scroll that has to have some meaning. To show these little thing and to have no explain explanation for them wouldn't make much sense.
I just want to know if Yamato is permanently "evil". He's not shown for plenty of chapters then we find out he's spiral Zetsu, he then just disappears after IT is activated.
Yamato got taken into the tree the second he was released from Spiral Zetsu (Guru-Guru). I don't think he's going evil any time soon, he just can't seem to catch a break with being stuck inside of trees.
Spiral Zetsu is still out there though, but I doubt he can do all that much. Wouldn't surprise me if Kishi just forgets about him.
If anyone turns evil, it should be Anko. She deserves some action. Her whereabouts are a mystery though. :I
