Exactly how explicit to make the episode is something we obviously spent considerable time discussing in preproduction. Ultimately, the writers and director wanted to be more explicit that the earlier TNG version of the "Blood and Fire" script had been. As Co-Executive Producer, I support and help them to realize their visions. We knew full well that no matter what we did to portray the Peter Kirk-Alex Freeman relationship, some fraction of our audience would be dissatisfied.
Ultimately, we let the "visual medium" of television be our guide. It's a tenant of scriptwriting to "don't say it, show it." You can have Spock say "I'm really, really, really, mad, Jim." Our you can have him punch in the door of the food synthesizer. The former says it; the latter shows it. We wanted to show their relationship--pretty much as Star Trek had historically done anyway.
Like I say: no matter what we had done, someone would be unhappy. Folks might recollect that in the original TNG script for "Blood and Fire," the sole indication that there was any relationship between the two officers was a brief bit of dialogue from Riker to the "Peter Kirk" character: How long have you been together?" The response: "Ever since the Academy." That's it. But that, too, was too scandalous for some and got the script axed. Heck , even when David Gerrold reluctantly agreed to deleted that single line, the script was still too scandalous. "We shouldn't have such incredible fear of an AIDS like disease and we shouldn't treat its sufferers like pariahs" was still just too darn controversial.
We got a lot of complaints from people who thought the characters' relationship should only have been mentioned, not actually portrayed. And, of course, we received lots of input from people who said "if all you are going to do is say they are gay, why would you even have the characters reveal that? How could that ever be a plot point? Why bother?"
So lots of audience members don't want a story about the characters' orientation (understandably), but they don't want their orientation to be revealed unless it's actually relevant and is a plot point (understandably) Otherwise it's just irrelevant pandering. So, we're damned if we do and damned if we don't.
We do welcome feedback on our "Blood and Fire" episode--as we do on all our episodes--even seven years out from its production.
