That would be totally awesome

It's cool to think about though, but I don't think it would result in any more of the show. Now that the world's at peace and all. Though CC and Lelouch get to be together forever... (Did Lelouch become immortal from overuse of Geass?)

I don't think there will be a continuance either. No, since he was given Code Geass by CC and he killed a different immortal, his dad, it's believed he has both.
