Wow..this is a serious deep twist. I was suspicious of Itachi being a good guy but I never dared to second think it.

I agree with how Itachi transferring all his eye power to Sasuke at the last moment with the poke is really lame but oh well. I am still confused as to why Sasuke only has 1 sharingan.

Itachi wanted to protect Sasuke maybe because he saw potential in Sasuke to kill Madara? No, it must be deeper than that...
Anyhow, If Itachi did want to protect Sasuke, I have no clue why he had to fight him
