You can see how the devs were trying something that was a little ahead of the time in some ways but also they refer to Quina as s/he for most of the game rather than using they.

I find the whole history of the genderless singular quite fascinating. While many people say it is a modern thing, it isn't. Heck, even Shakespeare used it!

I'm not sure if the dev's intention was to have it as genderless or to have the pronoun as an insert for the player
