After re-re-reading the new chapter I cant help but feel like the Zetsu's are being a little overly friendly to Obito

now we know that Zetsu's can change into people whos chakra they've had contact with, now they just so happen to know that Kakashi and Rin are being attacked by mist ninja's who's leader by this point is possibly under the control of madara, dont you think it would be quite easy for zetsu's to have copyed a couple of mist ninjas in order to get Obito worked up and want to go save his friends only to see Kakashi fail.

which would prove madara right about his views on life plus also it would unlock Obitos MS
