The girl is the healer from the other picture. The females are actually longer and generally have more weapon proficiency than the males, although the males are more muscular. The reason they are embracing and (in case you cant see it) crying, is that the male is running away. He has largely only white fur, which means that he has no magic skills. In less civilised times he would have been killed by now, but even though he has sympathy and is not allowed to be hurt by a tribe member, he is still less privileged than others and is kinda mobbed, so he's leaving.
