I believe the rumor is they added Suki’s mom. (Or it was actually announced in the cast list, I dont recall, and instead of looking it up real quickly, I’ll just type this pointless sentence.)
If not Suki’s mom, my next theory would be they just cast a woman for the town mayor. Maybe both? Dont really care as long as they don’t try to shove modern politics into the fact a town is run by a woman.
