Oof. His background fits pretty well with hers but I was hoping to have her be maybe 28 that way she's still pretty new to her career and it would explain why her worldview isn't as developed as someone a decade into it would be.
With their charismatic mom, I could see her having dealt with some confidence issues with being compared to her but also having to deal with the abandonment of her brother leaving her behind. I'm thinking she may have worked at the art gallery while in school while partying with the elites at places like Drones Club and getting mixed up in that lifestyle for a while, therefore not really paying attention to the world outside of that elite bubble.
I'm leaning towards having her be primarily a Lifestyle and/or Arts & Culture reporter for whatever prestigious paper exists there.
If you'd be open to maybe tweaking things a bit we could make the family connection work or if you've got other ideas in mind throw them at me!
