How is it ableism? Getting molested isn't a disability.
Lily uses words as cudgels and self soothing tonics. Abelism
sounds right if you say it angry enough. Don't listen for content just
listen. She's angry, she must be correct.

See? Ellie's got the right idea.
She likes things being proper in terms of gendered social titles. She can't have a fiancée, it has to be a
wife. Why? Because she thought
fiancé and
fiancée weren't gendered words when they are. Fluent in french indeed, Lilz.
Her newest insistence of Ex-sibling being used to refer to Courtney however?
Example From her Pokemon Retrospective:
My working theory is its because it has the prefix Ex in it and Lily loves the idea of treating Courtney as a Ex romantic partner. She's treated these last 6 months as a breakup of sorts. a very public one.
The SU Video she's working on
right now. Thanks Devil

She claims that she's booked a new appointment with her therapist to unpack the realization that the only positive relationship she had in her childhood was a lie and was actually abusive:
She's talking about her wanting a incestuous relationship with Courtney and being bummed out in adulthood about it.
In a video about a children's cartoon.

In that same vein, one of the gossip blogs made a connection to Lily's preferred age of characters throughout her writing career (14) and the age Courtney locked her out of her room.

To finish on a less disgusting note have Lily's final thought about the series and
rating all the Pokemon games from best to worst.
