The journalist love interest is a long-used archetype that extends beyond just these examples. I feel like these are the strongest and most consistent, and are worth a closer look. I always liked these characters and appreciated the fact that they had interesting careers that gave them some dimension. However they've had varying levels of development, and some of their nuances may be hard to quantify at first glance. I wanna explore em!
How do they differ in overall personality? Lois and Iris were both portrayed as kind of go-getters constantly rolling their eyes at Clark and Barry. What's something notable they've done or said that the others wouldn't?
How do they differ as romantic partners? Do their attitudes towards the hero business vary?
How do they compare as journalists? Lois and Iris work in print (or online) news, but Linda appears to be more of a media presenter.
I have some answers and ideas myself, but I want to hear from YOU first. Discuss!
