We were aware that the world we were creating was almost exclusively made up of male characters. We didn’t want to introduce a woman character just for the sake of doing so. A weak female character would not have made our world more interesting. Readers aren’t stupid. They know right away when a character is only there to fill demographic or ethnic quotas. So we tried to give Eva a personality and attributes that would make her a strong, interesting character, who would contribute to the story and not just be décor for the panels on the page.
