Aww I really want them to meet Kiyoshi!
Was hoping Kiyoshi can break through the language barrier or maybe with the aid of Raava.
It would be funny if she get another quest there again as I doubt Mia can do more than basic earthbending while fine against your usual monsters but come on, to become a true terror on the battlefield towards ancient monsters, better to learn from the best that is Kiyoshi.
Just checking how old is Bertha and George because I'm surprise they use to be soldiers as my impression of their age is early 20s like university students.
