Just as i planned. No true winner. Just as i expected from an Uchiha fight. First they fought in imagination land, then they showed off some mediocre moves, then they did moves that hurt themselves more than the opponent. In the end, neither itachi won, nor Sasuke. But in my eyes, i think Itachi kinda did better. Sasukes training and stuff all still didnt defeat itachi. He still had Susano, while Sasuke was out of moves. So Itachi basically did better but failed since he hurt himself more than he hurt sasuke.
