Hi all,
Since the show is ending I was thinking about a thought on how the show may end. Its just mainly imagination on my part =)
I just simply feel the last half hour of the finale should be devoted to the book of air as finally Aang will be the one to bring the closure to the series.
What I do believe is that Aang has to die on order for there to be balance in the world again. Partly because I believe that with his death, the many past lives of his will begin to reincarnate into new lives other than the avatar (keep getting this feeling cause if Aang dies in the Avatar state there would be no more Avatar being reborn, another point to note is that since the Avatar is reborn everytime with a pattern of water to earth to fire to air and over again, but the air nomads no longer exist for him to be reborn as an airbender hence the breaking of the cycle).
My theory is that since the past lives of the Avatar is reincarnated into different nations and lives, there is a bigger chance for the air nomads to return cause I still believe that the reincarnated past lives of the earlier avatars will be able to bend all 4 elements but not as efficient as before since now they exists as independent beings. (got this idea when Zuko uncle was explaining about the 4 elements and why the avatar is so powerful)
these are just some of my thoughts, not everyone will agree. hope others can shed some light on this theory with an open mind. Don bother flaming me cause its simply an opinion, thanks =)
