book data points for the Adrian Gender Situation:
grace lands on calling rocky "he" because he has a split second of panic in one of their first interactions and thinks "uhhh he or she or oh gosh this species might have a dozen sexes and use pronouns I don't even have words for um uh okay I'll just use 'he' because using 'it' for a sapient creature feels wrong. why does no one talk about how to use pronouns in first contact." personally I find this hilarious because it characterizes grace as being just about Gender Aware enough to conceive of and be cool with the idea of sex and gender existing outside of the socially constructed binary and is probably even down to use neopronouns for people, but also a) he still opts for "he" over "they" and b) is completely unaware that zillions of people are absolutely having fifth dimensional discussions about pronouns and first contact.
grace never refers to adrian by pronouns.
grace thinks of adrian as rocky's spouse specifically, not husband or wife.
there's a tiny bit at the end where grace says if he shined a light out of the clear xenonite of his dome then he could "see an eridian going about his business," meaning he's probably just using "he" as the pronoun for all eridians.
bonus round that doesn't actually come up in the text but is a metatextual thing I think some people are probably missing: "adrian" as a name on its own has a masculine connotation but grace 100% picked it because rocky balboa's girlfriend/wife in the rocky movies is called adriana "adrian" pennino. this genderless rock whom grace probably thinks of as being a he/him married to another genderless he/him is named after a female character who goes by a masculine nickname.
