10/10 for final episode.
Lelouch sacrificing his life so the world will be a better place. It was Zero requiem's true purpose. I'm sad Lelouch had to die for it.
The only bad things in the end is that C.C real name not mentioned. And Ougi survive, I hate him till the last episode. >.>
EDIT: I think it's possible Lelouch survived and he's the one with C.C on the wagon, because other characters who were previously though dead like Nunally, Sayoko, Guilford, Cornelia can come back. Maybe Lelouch will appear again on a Code Geass movie.
