Amid this Obito flashback, someone else is spying them, already.

[Sage6paths]

As titled, Orochimaru must be spying on them. How else do u explain Kabuto knowledge about Madara's prime and his rinnegan,

 

[skikasmarts]

i agree oro and kabuto knew alot about madara

 

[Pheonixking]

this is quite possible.i never thought about that.nobody knew what oro was up to it never said. plus rep

 

[peteriscoo]

Well he eventually joined akatsuki (his motives were itachi but thats oro being weird) and im sure he had nothing better to do. but zetsu said that no one saw obito kill those mist ninja and no one followed him back to madara. Zetsu would know.... I mean, he is the freaking land after all.

But oro is always a crafty one so you never know

 

[Simple Math]

possible

Yea i don't think they are being spied quite yet
I think oro found out about madara while he was in akatsuki, stole his body and ran off, quit akatsuki and did his own independent thing
