SO into this! There's so many options: Booker being uncomfortable around Nicky/Joe but trying to be cool about it. Booker being shocked when he learns they're a couple (and not just having 'release the tension' army sex). Booker whispering something to Andy about it, not realizing she is Also Gay. BUT ALSO Booker casually asking Andy to do a stereotypical gendered task, and both Nicky and Joe being like "oh shit here we go...". Or Booker saying something racist to Joe, and Nicky just Going Off.

And then Booker learning to be accepting of LGBT and feminism, and learning that he's being discriminatory because his culture was Discriminatory, and growing as a person ;_; Here for it.
