He definetly moved his fingers! He's alive and I think I know why he spared Sasuke's life...Itachi did all this to Sasuke to prepare him, to prepare him to the day when they both will fight Madara Uchiha and defeat him.
Itachi spared Sasukes life and Sasukes surely wants to know why....he has a lot of questions thats why he is playing Itachis game
sure most of you don't like me because of my english abilitys but my theorie is simple and TRUE
sorry but i'm so happy that Itachi isn't death that i couldn't wait till tomorrow to post it
