OKAY SO...
I read this article explaining the yautjan language made for Badlands, and it detailed how the yautja referred to each other with various forms of "you", depending on the relationship. "Wul", if they are talking to someone they look down upon or are disrespecting, "dau" if they respect the other person, and "kai" if they are close friends. And after that I noticed that Dek starts out referring to Thia with wul. Then, when they reach the Kalisk's den, it is dau, and after her betrayal, its back to wul until the end of the movie, where it's dau again. But he doesn't refer to her with kai... YET. So I had to draw the moment that changes.
I JUST FIND THAT ADORABLE OKAY.
(Also Kwei and Dek use 'kai' for each other AND THAT SHIT HITS ME HARD)
