Amira might sometimes seem "tamed" from living in the village, but she shows that she is not really tame.
Baimat is such a middle son sometimes.
Azel is the oldest, the leader, and the speaker. He is aware that what he says will have consequences, and so is careful when care is needed.
Joruk is the youngest. Flashy clothes, a bit irresponsible. He knows whatever he says makes no difference, as long as he doesn't badly insult anyone. And so he speaks freely, and kind of jokes around.
Baimat is the middle. Not the head, but old enough that he still has to be careful with his words. He cannot complicate things for his older brother by speaking too freely, because people might choose to take him seriously. And so he is very quiet.
