Wow, Virginia Lake. I like the actress and I think UFO is where I discovered her. I liked that she was a big fish, that she was the brains behind the technology for tracking the aliens. Oddly, I never thought of her as cold, more as executive/scientist. Many of the professional women I knew through my mom did come across as emotionally cool in the workplace. Outside work, at home and when not saddled with entertaining duties, they were quite warm and wonderful people.
Again, I have to look at the time frame outside the show. The late sixties is the sexual revolution. Multiple liasons did not make one a bad person, just sexually active. This is the time of Playboy, Hustler, and Penthouse; of the hippie movement in the US. It's a time when women were being allowed to acknowledge that their sex drives are just as strong and urgent as that of the male.
Ginny going from Craig to Paul: can you say rebound? I never saw that as a lasting relationship, but more as having lost Craig, Ginny turned to the only other person who might understand. (Heavens, I'm painting Paul as an understanding human being) I think the writers weren't treating Virginia Lake as any more of a three dimensional being than they did anyone else. They picked topical actions that made her a "modern" woman", they weren't really developing her character, just picking up on what they thought women wanted to see in a "liberated" woman.
Everyone cares about Straker. SHADO is still in its formation period, it's barely online and Straker is the ramrod of the organization. In many ways, Straker is a messiah and the Colonels are his disciples ... (Oh, heavens, does that make Ginny the Magdalene?) So, Ginny cares about her boss. Would she ever cross the line of command to see him as a man and want him that way? Good question. Ginny is a civilian thrust into a military world, mostly male dominated in the time of writing. (The big prohibition is enlisted and officers. Too much abuse of position of power from one side to the other; therefore officers are forbidden to have relationships with enlisted personnel. Relations between officers are at the discretion of the officers. Too wide separation in rank is frowned on as some people have rankly abused their positions to coerce lower rankers. Not a problem between Foster, Freeman, Lake and Straker.)
Did I see Lake and Straker as a romantic item: no. Not during the series. Had things gone farther, had the show developed and time progressed to where Straker knew someone else could step into his shoes successfully, then there might have been. Although on some levels Straker and Lake are too close together psychologically. Virginia has had to fight her way into the position she had in the civilian world and probably understands a lot of what Straker goes through.
Given the chain of command, SHADO really couldn't afford to pair the four primary command personnel with each other. They really had to find outsiders.
Given fandom, the pairings are ... whatever we desire. There's a way to justify anything, including evil influences.
I appreciated seeing a woman in a position of command and power who wasn't super human, who was fallible. As noted above, I didn't see her as cold, but as professional, something a woman has needed to be successful at the time of filming and well into the 1980's.
Of course, I haven't seen any of the shows in a decade of more, which means I'm relying on my very very sieve-like memory. In the US, professional women are still a lot more like Virginia Lake when on duty. Off duty, that's a whole different scene.
Replacement for Alec ... sometimes writers just don't realize that there has to be some kind of continuity, explanations for missing people. Mind you, I think the show wasn't shown in order in the US so I never caught on to people shifting places ... LOL.
My Ed pairings: dubious at best. Kelsy is outside of SHADO completely. Cheri was a ... biological imperative, although I haven't explained that yet. Virginia: Well, Ford is not exactly a normal pairing at this point. I may have to make it work in another universe because the world of skulls and weapon test is not going to end well. The other problem is, I don't necessarily go for romance in my stories.(Oh yeah, I've put Mary back in his life twice ... although I have yet to finish things on either of them) .... hmmm, although I could see a situation in which ...
