A history teacher asks when WWI was, our smort protagonist answers "1930s", which according to their history teacher is correct
→Amber is a sped and bona fide retard, devoid of basic knowledge and too prideful/sure of herself to look up the actual answer
Several places in the story are the "best" at what they do and/or have retarded names, e.g. "(Jaslyn's) was the best clothing store.", Rosebud hospital was the biggest hospital in the United States. It was known for well[sic] doctors...", her school is called Hazelnut High
→Her need to have everything be special
Scottie, who is an obvious Amber self-insert, has a crush on a character called Stephanie, who also likely is a self insert
→Amber is a narcissist, and the only thing she'd ever truly love is herself
Scottie has two pets in the story, Rainboww (yes, spelled like that) a rainbow-colored parakeet, which she says is the only one in the world (which she somehow got from her boyfriend), and Snoww (also yes, like that) a black rabbit she saved from "a garbage[sic]"
→her need for everything to be special, own all the most unique things (in this aspect compare it to her boasting about how Rarity is some rare breed from France(, her retarded naming schemes, narc fueled savior complex...
Scottie wants to lock away the parakeet because it reminds her of her ex
→Amber is a horrible pet owner who'd abandon her animals if they'd inconvenience her (for which she absolutely deserves to burn in hell)

All the descriptions of food in the story
→Hogynn is an event horizon fat fuck and can never not think about food
Scottie is upset that everyone else's probems are so much "simpler" than hers (for context, other characters in this story have been hate crimed into a coma, have cancer, are getting groomed, or are teenage moms, Scottie's big problem is that she is getting TEH GAY FEELS), other people's problems are usually only contextualized with how Scottie feels about them and how it affects her
→Narclynn needs everything to be about her, all other people are secondary
Scottie has a hissy fit when her younger sister (14) is dating her ex boyfriend (17/18?). She is not upset because it's weird and gross, she's upset that she gets to "flaunt" him like that
→actual relationships mean nothing to Amber beyond what she can get from it, be that function or prestige
The younger sister, who is stated to be a vegetarian in an earlier chapter, casually eats a hamburger in another chapter later
→Amber cannot keep track of the things she makes up, much like how she can't keep her lies consistent
Scottie is upset over her breakup, though mostly just because she wasn't the one to initiate it
→See anytime fatty was dumped by her current caretaker
I'm sure you could find a lot more, but that's all I can think of right now.
...yeah I've read these stories way too many times plunging my normie friends into gorlworld (though I have yet to read her lesbian BDSM fic feat. Kate Winslet she wrote for Becky). I'll accept my puzzle pieces now.
