Ok just a random thought...you all remember how "Tobi" had the silly child-like personality & would occasionally do a 180 with his serious Madara impression? Split personality deal right? Who else had a split personality with a silly, funny voice side & a serious deep voice side?? ZETSU!! I don't think it's coincidenced that the person closest to Tobi/Obito also has a dual persona..I think Zetsu has a bigger role in all this than we think. People tend to overlook Zetsu & consider him just an experiment for Tobi's use but I think he has played an important, yet to be revealed part in all this. During the course of this entire series, Zetsu is one main character who we've literally learned close to nothing about! He's still a complete mystery even his full combat skills aren't known. I think Kishi purposely took this path to leave his story to be told at the right time which would be now! Zetsu is clearly integrated into Obito's body somehow evidenced by him dripping white goo, rejuvenating lost limbs, etc. I also believe Zetsu is somehow connected to the 1st Hokage since he seems to posess a mokuton type justu. Just speculating.
