True it could be a fanfic, though I doubt
@Erta Wanderer would be posting about fanfics.
Doesn't make it better written though.
As far as I am aware saurus/lizardmen were genderless up till now given the whole spawn-pool thing.
Plus, given their alien nature and focus on the great plan I'd assume Lizardmen wouldn't really care about pronouns to begin with and simply view that as a silly thing the younger races do.
In all honesty I'm mostly just dissapointed that they didn't actually do anything with it. A skink being influenced by its time among mortals could make for an interesting character, and something like adapting their language and social constructs makes perfect sense in that case. It'd be a great way to examine these aspects, especially using such an alien character as a skink or saurus. But that'd require them to go more into depth than what they've done in this snippet.
