What people seem to not understand
Ok so the last manga seems to be a bit confusing for most people regarding on what happend between obito and kakashi, and here is what i think of it..
Obito was deffinetly pin down by kakashi, kakashi had a perfet oportunity to kill him but he stoped himself. Then obito pulls himself up while he is talking and then they show obitos sharingan, which is why i believe that kakashi fell in a genjutsu. Right after they show obito's sharingan obito stands up and walks towards the raikiri and stabs himself, and kakashi was freaking out and remembering What happend with Rin and everything, that is why i think obito is just messing with kakashi's head.
It can't be real because that was obito's left side (where the heart is) and the zetsu body that obito has is on hos right side, so it isn't the zetsu body or senju DNA.. And if you look in his chest whole it looks like it is dripping blood because it is drawn in black, not white like when his right arm was falling off.. So it isn't the zetsu body, and it isn't real, it is just a genjutsu.
Prove? The last manga pages...
