There is that scene after Astarion reveals his secret where everyone comments on him. That's about as much of a group conversation we've got. Even then, they each say closed dialogue lines and don't expand on each other, so no need to use 3rd person pronouns. I'll pay this scene attention next playthrough.
Is there anyone here who toggled different gender to sex in a play through? I wonder in which scenes BG3 implements this?
