As Diana Byrne-Ward, you are the younger apprentice secret agent to the main secret agent of the show. You are efficient, helpful, and enthusiastic. As Ursula Dulcimel, you'll be pretending to be all those things as an agent named Roxy Angel. You're actually a clever and slightly sadistic villainess. As both, you have a sensual and maybe even throaty voice. The audience is supposed to tell by your voice that Ursula Dulcimel is drop dead gorgeous. That Diana sounds like this but does not look like this is important to the story.
