I see as deconstruction of MLP FIM after re watching some episodes & comparing story, characters, mythos & archetypes made a small list as an example
1.pearl if you think about it a deconstruction on twilight sparkle they share a love for teaching, history of there people, the magic comes out of there head, if you think about it pearl was in love with rose quartz but in the beginning it was more student teacher thing in the vain of twilight/celestia only taken to more realistic conclusion(that's my theory anyway) also pearl to me feels like what twilight herself would be like thousands of years in the future with most of her friends gone basically keeping it together but with a few wrong steps away from going jack in samurai jack season 5 levels basically pearl is what could be in a later point in her life
2.amethyst is soft deconstruction of Rainbow Dash/AppleJack & most tomboy archetypes in girls cartoons really similar to that by taking a more realistic approach & having some consequences for amethyst actions specially when she goes POOH after her gems gets some level of damage
3. the diamonds leaders of GEM empire I notice that
White Diamond = Celestia
Blue Diamond = Luna
Pink Diamond = Cadance
has anyone else notice it?
4. rose quartz is deconstruction on celestia: being all knowing leader, leader for a whole(in rose case strong chuck) race, telling all pony/gems that there something special about them if just work hard enuff but also the dark side of it like even good people can have few demons like rose killing pink diamond I mean imagine reaction of celestia telling twilight she killed somebody because they were very close from ruling equestria?
