Something done purely for the facial expression. Artemis tends to be the object of any "Big Bad"s desire, so she ends up running away. A lot. And then Lukai and Samantha come and save the day with huge friggin' explosions and stuff like that. Whatever.
Artemis' braids are both fun and irritating at the same time. Tried to give her an outfit that would be a parallel to Sam's. It's sort of like the suit Sam wears, but I referenced clothing from the 1890s and stuff around that area to make it more girly and everything.
