I do hope that she will have something new and awesome. However, I do not hope that it will be the exact same as Jinora, with being another spiritual guru. Actually, you know what would be nice? This is an idea that I have had in mind for a while. It may not be a great idea or actually air on the show, but I personally think that it would be nice for Ikki to be an airbender who does something different from the norm of airbenders. I've been waiting for a while for airbenders to find out that they can squeeze the spines, ears, or lungs, of their opponents. Although Nickelodeon will probably not go this dark, especially after bloodbending, I would love to see an airbender who doesn't carry out the whole pacifistic legacy. I guess that we got Yangchen, but it would be nice to see someone who is an airbender and only that, challenge his or customs and roots. I think that it would be nice for Ikki to give airbending a new name and come up with her own subskill that would be very handily in combat. Those are my two cents :D
in order to "master" airbending and get your arrows, you have to master the 36 tiers of airbending. aang was at 35, but inventing a new technique counted as his 36th. you don't always have to invent a new technique to get your arrows - i mean think about it, there's no way that's possible for each and every air nomad to invent a new technique - they would start to get less and less original.
anyway...i remember reading about this as canon many times, but how do we know it? i don't remember seeing it in the show anywhere.
I'd let her just have a childhood and not force the entire weight of being one of the few airbenders ruin it. She's also a bit too young to need to go anything but act cute and provide a funny line of dialogue.
I think Tenzin's kids will be downplayed this book. Let me rephrase that: I think Jinora will be downplayed this book. The other two kids will get about the same screen time/lines as they got in book 2.
I think Ikki should be more like book 1 was she was funny! But most of all i want to see all the airbending kids kick butt!! They showed great potentail whilst helping Lin and most surprisingly Meelo! So just imagine what Ikki and Jinora can do!!
