Third person gendered pronouns are never going to be used in BG3. For starters, you don’t use them in direct dialogue, you use I and you.

Secondly I can only remember one instance when you overhear NPCs talking about a PC and the goblins call him Blade of Frontiers. Kethric Thorm calls us True Soul; Larian is taking the efficient route of titles and honorifics.

Thirdly, when we talk about npcs, we use _their_ gender pronouns or names.

Should an NPC call us a gendered title of sir or ma’am, that’s about all we’ll hear from gender identity toggle.
