Maybe Aion just like mocking god? How he wanted to be like him? Also in eps 23 before he died I think he said something like "Eloi, eloi lema saba blabla (I forgot)" which was like "god o god why did you abandoned me" in the bible? Wtf thats supposed to mean? he's angry because he failed on becoming god? so he decided to mocked god?
also I'm wondering what're the reactions of the people in japan regarding this eps, mainly christian ones. Rofl that'll be hilarious.
I bet they're squeezing their heads thinking wtf is this ending.
