I just realized, had the regions be truly based on their nations, Galar would have spent at least 100+ years deciding if they were Catholic or Protestant, while Kalos remained mostly Catholic.

Meaning that in Galar, they too have a Guy Fawkes Day. ALSO meaning, that in modern day Galar, you can buy fucking Guy Fawkes masks and pretend to be V for Vendetta instead of a terrorist or a protester, depending on your point of view.
