[ oh elsa this is a huge can of worms how is she going to explain this without going into a huge history lesson. ]

Well, I've never heard of a firebender born in the water tribes. [ there's a good nature about this, so it's not like she's trying to talk down to elsa on the subject. ] They usually come from the Fire Nation, and earthbenders from the Earth Kingdom.

[ please note the 'usually". ]

But it also kind of runs in the family? Sort of? [ now she's just making it more complicated for herself. it's weird enough having to explain the mechanics of her world when she's honestly never thought of it any other way. ] See, I have two friends who are brothers, but one's a firebender and the other's an earthbender and they got their bending abilities from their parents.

[ in short: bryke is on crack. ]
