anyway, i thought itachi was 12 when he massacred his own clan, but it says that he was anbu at 13. if he did do it at 12, then i guess he would've left the village right after therefor, not being able to receive anbu status. this is really weird because during the flash back, sasuke says that he is the same as age itachi when itachi graduated (7). which would mean that itachi was 12 since they are 5 years apart cuz sasuke is or should be 12 right now. but i guess itachi could've been 13 if one year has passed since the first episode til now.
