U3br 3])iT : This is gonna be a spoilor heavy topic if you never read the manga yet.. LEAVE~!.. Now!! right away!! lol and dont come back >< lol

no.. itachi never knew kakashi could use it at that time, so he means someone else, prehaps its like Obito or something.. although he died could be like a plot twist or something that he survived XD, or prehaps that the 3rd user is the akatsuki leader, since in the last panel of chapter 238, the leaders eye's black rings connect at exactly 3 spots, XD but it will be explained eventually in the manga.. probally -.- lol

G0$ 3])it : also what im curious about is what the "true meaning of Uchiha" is that sasake and itachi read under the tatami mat thing XD

1 more edit XD : of maybe the aksuki leader is Obito!! lol jus a thought XD
