i hope i Edo rin do make an appearance to fill in the gaps, if not then here is my predictions: i think it might of been madara who ordered two zetsu's to get kakashi's and rin's chakra signatures and play out the death of rin in order to anger him, that way he will use his hatred and anger and sharingan as needed for his plans, also i think rin was already dead and madara used this knowledge to his advantage and tricked obito. i highly doubt kakashi would murder a comrade unless it wasnt a comrade, maybe a zetsu posing as Rin? Kakashi's keen sense of battle finds out that Rin is an imposter and handles it right then and there, this is when obiot shows up it and sees kakashi killing what may appear as Rin but its actually a zetsu. WADDAYA THINK????????
