I'm not sure if we're going to or not because what happens is I'd always love to see certain characters back, there's so many. Some of it has to do with, if we want them back, are they available and the other aspect is do they fit with the storyline we're telling.
You will never get to the irreducible definition of anything because you will never be able to explain why you want to explain, and so on. The system will gobble itself up.
