I approach every part I'm asked to do and decide to do from exactly the same angle: who is this person, what does he want, how does he attempt to get it, and what happens to him when he doesn't get it, or if he does?
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.
