Maybe we could talk about things in the series that are uncertain. Why does Geass exist? If it existed for thousands of years, then how come so few people know about it? What powers do C.C. and V.V. have that were never stated?
In that one episode, C.C. said that she wanted to end her existence in all worlds, but when she killed Mao, she told him to wait for her in C's world. The former episode that I referred to did take place in C's world, but no dead people were there. Where do dead people really go when they die in this world? Do they go into nothingness, and if so does that make the apparent religions of some characters meaningless?
