Since "Tobi" was introduced into akatsuki by zetsu, it seems like pein, zetsu, and tobi are the only ones to know of tobi being in charge. I wonder if itachi knows or can sense that tobi has the sharingan. It seems like he should be able to realize, but since tobi/madara is so badass, but just acts like an ass, maybe that is enough to make itachi not really care. Itachi does say that there are only 3 able to use mangekyu (sp?) Is the 3rd person tobi or kakashi?
Just something thats been on my mind.
