From the TOS Series finalemay sound a bit nOObish, but this stuff about women can't be captains eluded me so farsomebody got a link, please?
JANICE: The year we were together at Starfleet is the only time in my life I was alive.
KIRK: I never stopped you from going on with your space work.
JANICE: Your world of starship captains doesn't admit women. It isn't fair.
KIRK: No, it isn't. And you punished and tortured me because of it.
JANICE: I loved you. We could've roamed among the stars.
But that could easily be interpreted in many ways. It could mean he can't be in a relationship while as captain.
