Mickey's girlfriend (Nasha) and the girl in love with Mickey (I don't remember a name) talk to each other about Mickey and whether they can both date him or not
I don't remember a scene with 2 women talking about something else, feel free to correct me

This actually passes quite early - Kai and her girlfriend Jennifer discuss planetary logistics after the colony figures out how to breathe without masks on.

Later at a dinner, Ylfa and Kai also briefly talk about sauces and Jennifer

Jennifer and Kai are talking about why they are still living in the ship and eating crap food even after landing "ages ago"

Ylfa and Kai have this short exchange during the dinner about Jennifer:

(Marshall asks Kai if she's okay and she says she is)

Ylfa: I’m glad to hear it, Kai. I’m so sorry about Jennifer. I hear you were extremely close. Your best friend. [whispers] But I knew you’d stay strong throughout it all.

Kai: Thank you, ma’am.

During an expedition, Kai Katz and Jennifer Chilton talk about having to still live in the spaceship and eat TV dinners and about the color of the cave. Ylfa Marshall and Kai very briefly talk about Jennifer's death during their dinner together with Mickey 17.

As mentioned, Kai and Nasha talk about the multiples of Mickey once, which is about a man.

There's a scene where Ylfa and Kai are having a conversation at dinner and things other than a man are discussed. For example, they talk about Kai helping repopulate the planet.

-The name of the second girl flirting with Mickey is ”Kai”.

I also don’t remember any scene where two women are talking with eachother of an other topic...

two characters at the beginning, jennifer and kai (the girl in love with mickey) talk about the planet / growing crops / the tv dinners
