But the messing with the chakra signature shows that there is a possibility that Zetsu can hide/mask a person's chakra signature. I'm not saying you're wrong, but do you remember saying there was no way Madara could survive the release of Edo-Tensai... and low and behold...
P.s. Sorry about the late response... little man is really fussy today and trying to go on a date with the wife tonight.
