Judging by your posts you never stop the zutara xD
I am a bit apprehensive about the final chapters, even begin to form a theory of how it will be, I was joining the views and comments of Mike and Brian about what they planned to do in the final chapters in the interview he gave last year, with the Dylan gave comments in a podcast, with the views of Ruftoon in devianart and in the last interview of Mike... All these comments as an writers head of Avatar (With the Dylan exception ) lead to a similar conclution and all indications are that it will not be a happy end "somehow". I am sure that it will be exciting and original, as I am sure it will not be very happy, perhaps as Cowboy Bebop, a final you can only hate or love, but it is conspicuous by its originality.
mmmm sorry!!...off topic
