RM: Okay, next I know I'm going really left brained and you can call me a geek because I am, but in "The Fortuneteller" you have a pair of twins...kids...one is an earthbender and one isn't. So is bending genetic, or is it some sort of spiritual thing? How does it work?
BK: Mike and I just got new puppies. They're brothers. They have the same mother and father. Same litter. Mike's dog can just sit in a crate and be happy as a clam. My dog just loses all control...everything. Who knows why these things happen? They're beyond our full understanding.
MDD: Yeah, Katara's mom and dad weren't benders. Maybe it's a recessive gene. I've always seen it as more spiritual connections, though. A little bit mysterious...
BK: I mean we've definitely talked about it. I think, again, sometimes we might not know...it's more of what we don't want it to be. We didn't want it to be like there is a lineage...a royal family or something...and these people can bend and then there's everyone else as non-bending, people who never will. Some sort of caste system. Mike and I are more attracted to more of the flux type universe. The only constant is change, variation, that sorta thing. I'm sure it's a bunch of factors.
***Interviewers note: About 20 mins after the interview, Bryan came back to me and we spoke a little more about the basis of bending off recorder. He described bending as more of a talent. You have some genetic basis for potential, but you could go your whole life without developing the talent into ability. Some people have more inherent talent than others, while others with minimal inherent talent can still develop it through hard work and practice. He reiterated a connection to the spiritual energies is the underlying basis. How it manifests is based on upbringing and experience.
