I could also tell you my name is Clancey and I once caught a 14 pound swordfish in the Bering Strait but that doesn't make it true. Yda is the only Scion that consistently has no fucking clue what's going on and needs Papalymo around so that she doesn't bunk up the Scion's operations too badly. She's also really good at not being caught, and you know who benefits greatly from being really good at not being caught? Fists of Rhalgr.
Also she seems really invested in the Ala Mhigan resistance. In the short cutscenes where she interacts with Papalymo in an area that is quite obviously a resistance staging area, she gets all worked up about Papalymo saying they need to take things slowly.
Also x2 god forbid a region that is very firmly connected to the rest of Eorzea have some racial and physiological diversity.
