remember when sasuke had a fight wid itachi and he fainted then he woke up next to tobi and tobi was about to show sasuke his face but itachi planted amaturaseu into sasuke so that sasuke didnt see tobis face but whyy????![]()
It wasn't to avoid seeing Tobi's face, it was to kill the bastard with a surprise attack before Tobi told him the truth about Itachi.
