Well, the chapter was a little short but good. But I don't understand the thing with that Genjutsu. If Sasuke and Itachi both know that the other one uses a Genjutsu why can he get into it? I mean if that kunai and shuriken moves were just Genjutsu (I don't think, but it could be) why does that "scene" exist? Isn't it like only the weaker one could get into a Genjustu? Or can you know it is a Genjutsu, see it but it don't affects you? I don't think the sharingan-users are the same like a Sakura who can break the Genjutsu.

And was it stated, that the one who loses is eyes really lose it? Maybe he only lose the "sharingan-ability" and not his eyes or goes blind...?
