where are they going i think i know. the one who know everything is... SO6P(to be specific i ment his knowledge or the scrolls that he left after his death in the uchiha secret place when there a scroll that only uchiha can read). :rofl: and y i would think that? one reason because oru have no interest in that war ( he said that ) so he is not going to go to the main battle field.
and other reason is that sasuke asked him where they are going and oru said : "to a place you know very well" so i think it is konoha village and since sasuke want "some answear" i think he might get them from a secret scroll hidden somewhere that complete the information from the scroll sasuke already have. or he can just go to the elder of konoha and ask them about itachi or something and than kill them.
