yes i could be over analysing the picture...
and yes hair is not always the same size but the size difference here is quite big...though it could still be itachi
and as i think someone mentioned before that someone might have told itachi about the mangekyou...this could be the person over looking what itachi is doing or aiding him..
at this time i cannot provide any solid evidence as there is none to prove it...there can only be opinion...and thats all this was a different opinion due to a difference in hair...if the hair was any shorter i wouldnt have said anything about this...but it could be just a stuff up from kishimoto...which is most probably the case.
harsh..heh
ive seen worse from you.
