In a way it feels strange to do all three of these characters together – like, it makes sense to have Hau and Gladion together because they both fit Pokémon’s existing “rival” archetypes, and it makes sense to have Lillie and Gladion together because (uh… SPOILERS, I guess???) they’re family, but the three of them don’t fit together quite as neatly at first glance.  In fact, though, they play off each other in ways that I think are worth talking about.  Hau, Lillie and Gladion all act as foils to one another – Hau’s carefree optimism, Lillie’s self-effacing dutifulness, Gladion’s edgy pragmatism.  All three of them also have certain issues with their parentage (granted, in Lillie and Gladion’s case, it’s the same parent), which is important not just in terms of their own characterisation but because tradition (and, by extension, ancestry and inheritance) is a minor theme of Sun and Moon.  Lillie’s relationship with her mother is also basically what the entire climax of the game turns on.  So let’s talk about these three, their personalities and what happens to them, and see what we can be come up with – starting with Hau.
