Also, even tho you didn’t ask for this, but because you mentioned she’s a character in a story, and because other comments also vibe with my first impression of “Idk, sounds like an asshole with random facts sprinkled on,” consider looking up “save the cat”? Note that the thing that makes a character likeable is their choice to actively do a good deed for some extrinsic reason. Example: A train operator on a moving train sees someone tied to the tracks. They pull the brakes. The train stops, and the victim is saved. Meh. What a norm-core thing to do because it barely seemed like they had a choice. If someone else were with them saying “oh my god, if we hit the brakes now, we could derail!”, and the operator low-key knows this and immediately pulls the brakes anyway - that’s cool, because they had a choice, and they chose to do something difficult but good for someone else. Or a person being an asshole in general and poor, but still paying for the dude in front’s groceries when their debit card declines. That’s cool.
Or person going out of their way to cheer up their friend that they noticed was almost too good at masking chronic depression. That’s cool, too. Dr. House without his medical malpractice shenanigans to actively help strangers is just an asshole. …If all this was ultimately excessive and unnecessary for someone else, at least this has been an exercise for me think up save the cat examples. I hope these spoiler tags work. Ta
