No, but when Captain Jack (YAY!) gives them their cover identities, he tells them they're going to be posing as a couple on honeymoon to Mars, because it's the most low-profile cover he could come up with. And with two lines of dialogue, JMS shows that in his universe, gay marriage (interacial gay marriage, in SPACE, no less) is so common that nobody looks twice. (Kind of like how the shocking thing about Susan and Talia wasn't that Susan was in a relationship with a woman, but that Susan, with her issues, was in a relationship with a PsiCorps telepath.)

(I love you, Trek.)

(I hate you.)

(Stop sucking.)
