Saskue's Role
I think after the recent chapter, saskue is probably shocked that Madara is not only alive, but that he actually died. Reason being is because tobi told saskue that he was Madara Uchiha. Now that Saskue knows this, he believes all that he has known before were contradictions. Well that what Im getting from Saskue.
My question to you is, How does orchumaru have all the answers? wouldnt it be best to find Madara and ask himself. Granted i dont want him to fight Madara, that would be instant death. But how would orchumaru know about this? I have a slight idea since he worked with Danzo. But the time of the uchiha massacre was way after the 4th hokage death. And orchumaru left the village before the 4th was dominated.
