I loved this anime so much and that ending weather or not he really died was needed. It is alright for him to live as long as nobody but CC knows it. I will not say I think he is alive though there is BIG SUPPORT FOR IT, and even if there was none, sunrise likes to play god and Lelouch is thier money Jesus. He will rise again.
Anyways I loved the end. Why did nunally see shock images? I thought only people with the code could give people shock images.... Another reason why he maybe alive.
ANYWAYS good ~Fin~
