I found Jasmine in Artemis very believable. Eva doesn't need more depth, that's not the issue. Her interactions just aren't believable. It's not a gender thing, either, because I wouldn't believe a male version of Eva. Maybe because I can't believe that someone would ever have that much power and be a jerk at the same time?
