Where was Kakashi?
So here I am, re-reading Obito's flashback moment in the manga, when something odd came to me (as these things typically do when Im tired), and be warned before continuing: I am 100% over analyzing something that is basically irrelevant. Enjoy :D
So back in chapter 605, the chapter where Obito went on a psychotic killing spree over an event that clearly has another story too, I noticed something rather odd: Kakashi and Rin's placement during Obito's massacre. Allow me to elaborate:
What you're looking at here, on the top panel, is a picture that details the positions of the key players. Obito can be seen towards the forest down at the bottom middle, and Kakashi and Rin can be seen in the middle dust cloud towards the top. It is also clearly shown that Kakashi is surrounded by the Mist ninja.
This image shows at the top right panel that even though Obito had drawn the attention of the Mist ninja, they still were relatively close to Kakashi and Rin's bodies. Obito then charges towards the Mist ninja, thus charging towards Kakashi and Rin.
Now, if you look closely here on this page, on the panels to the right we are shown quite clearly that Obito is only feet away from Kakashi and Rin's bodies.
Obito then runs to the Mist shinobi he speared, which should place him within 5 feet of Kakashi and Rin. It is here I would like to point out the mistake, as what happens almost immediately next is-
Logically, the placement of Obito, Kakashi and Rin SHOULD have resulted in Kakashi and Rin being speared to utter death by Obito's attack. You could theorize that maybe the attack only sprouted from the ground at a long distance, thus placing Kakashi and Rin within the safety zone of the attack, but to that I would like to point out this:
Not only does this show that the attack sprouts within 5-10 feet of Obito (placing Kakashi and Rin nearly smack dab on top of the branches), but also just look at the amount of blood coming down from the sky. Even if somehow Kakashi and Rin didnt get hit by those things, they would have either A) drowned in blood, or B) be covered in blood in which case Kakashi should have waken up taken one look at the place and go "WTF HAPPENED HERE??!!". Plus, if Obito truly hated Kakashi the way he does now for "killing" Rin, as I have shown with undeniable proof; Obito was within walking distance of an unconscious Kakashi. He could have walked over to his body, slit his throat, retrieved his other MS eye, and potentially unlocked the Rinnegan on his own. After all, in the previous chapter Zetsu upfront told Obito that with the Senju DNA in his arm, and with both of Obito's eyes together, Obito might unlock a power never seen before. But hey, maybe that's just me.
