Secretly? I never said it was secret. Just because you don’t see them kissing or whatever on screen doesn’t mean it was secret.

Again, assuming every character is heterosexual just because you don’t see them do anything physical with someone except in a heterosexual way while the episode is being shown doesn’t mean they aren’t doing it when you don’t see them or that everyone isn’t aware of it.

For all we know, they were together for at least a year and threw a big one year anniversary party. Why just assume such a thing never happened? We don’t see what happens to anyone on any Star Trek show for more than a total of around 45 minutes at a time, sometimes spread out over weeks.

And, as I said, I know what two people being attracted to each other looks like.
