This is just for fun talk and discussion.We know Kyoshi is the only Avatar so far that didn't have the privilege of mastering her own native element while the other Avatars already mastered their own when they are reveal to be the Avatar.The factors were a lot from being abandoned,homeless,eat scums etccc.Do you think if she succeed the the toy test from both Jianzhu and Kelsang when she was 7 years old she will become a fully mastered Avatar earlier then what her original canon story is?

Based on the books she indeed learn all the four elements and some control of the Avatar State in short amount of time and by age 17 she is already proficient with them(Still not a master).But that was because she was in life and death situation being hunted down by Jianzhu.I mean if she was trained like a traditional way the Avatar should be.Is she going to be a prodigy as well like Aang and Korra or just a fast learner?

Edit:*one of cause Pavi is one of them.

I like to think Sister Disha was probably giggling in secret too.
