Re: list of who saskue is seeking, the contenders!
while i have been of the belief that it will involve the hokages(as suigetsu randomly mentioned rds, as of the latest chapter, i think it is someone who is still living(as they all sensed the chakra...and it disturbed them(i highly doubt that the chakra sensed was narutos or kuramas, as sasuke is many many many many miles away.....(i think at least 70)....
so in my opinion, though you may hate it, i think a living canidate, would be kagami uchiha....he is old enough to have seen the uchiha, almost from the time they joined the village, till the extermination. He is a member of a hokages team, and he hasnt been confirmed dead yet. He could be the son of izuna, and a father of shishui...the main problem, is that he so far has no character developement, and we know less about him than the white fang.
shishui is dead, face it....if he was alive itachi wouldnt have ms....it is likely that his body was amertersued by itachi, so noone could get to his body....and izuna is REALLy unlikely....as he would need something as strong as senju dna, to keep him alive....so kagami is an option.....
regardless, i still think we havent seen the last of the hokages.... i think something will involve them...
