I bet Orochimaru has taken over Madara's Body.
That is why he is cloaked.
Why clock him otherwise unless you are going to reveal that Orochimaru has a new, familiar body?
Seriously, I'm loving the way these two chapters have unfolded. I'm feel more invested and interested in this then I did for Shippuden at times. Maybe cause Orochimaru was always more of a messed up and interesting villain.
Love breeds sacrifice, which breeds hatred. Then you can know pain - Pain
