Do you guys think the line ofAir Nomads/air bendingwill continue into future generations realistically speaking, since the whole bending gift seems to be lottery? Aang only had one air bender kid. Who is to say all Tenzin's kids will have air benders as kids. Can Kya and Bumi's children (if they have any) be born with the air bending?

My first thought is that it all comes down to luck if any of Tenzin's have children of their own then there would be a chance of them either being able to bend (depending on where Pema is and if any of her relatives could bend) air or water or not to be able to bend at all. I guess the same can be said for Bumi and Kya.

However from what we've seen I'm guessing Airbenders pass the gift along like brown hair. We hadn't seen any none benders in Aang's flashback. So maybe all of Tenzin's kid's kidswill be benders. If they do and their numbers explode they could have a future series character make a comment about it.

The second is just speculation so thefirst thought is more likely

I think it's pretty safe now.

Remember, spiritualism is what made it so every air nomad was an airbender, and Aang/Tenzin made sure that there was a very spiritual location filled with acolytes to the ways of the airbenders, so i think Tenzin's kids will have airbenders for sure, and once that generation breeds there should be enough to really make a population grow.

I hope so. I am interested in bending elements works. It seems to be genetic on some level because unless people marry outside of their nationalities any benders born into their family have their native element. Chi and spiritual elements play a critical part to it as well. I assumed chi is why the Avatar can bend all four elements and why no matter what his or her descendants can never inherit this ability to bend more than one element. It is fun to think about.

It sorta makes you wonder if an Avatarcould pass on the ability to benda differentelements insted of their natural one. Like if Korra had a kid who could only air bend. I think that would be interesting

I think you guys mean native element. If Korra had a kid who could air bend without the father being from the air people it would be interesting. It would mean that as long as the Avatar exist the four elements can continue to exist in the world and if another genocide happens the element would exist. I don't think the creators had that in mind, but it would be an interesting way for the Avatar to maintain balance.
