[Theory] Madara is taking control of obito.

Well now that I thought about it.
Earlier in the manga Madara made a black side of zetsu and told obito that to think of it as being a part of me(chapter 606 page #18). Then in the chapter 637 page #15 obito had a black side of him which exactly look like black zetsu.
Could it be that Madara is now and always have been, a part of obito?

That can very well be the case. Well, I for one, hope it's true, but we'll see...
