I stumbled into a few Fang x Janet fics a while back, mostly crossovers between 'Detroit: Become Human' and 'The Good Place'. What struck me wasn't just the robot meets afterlife architect thing, but how often writers explore trauma and memory. Fang, with his guilt over North and the Jericho uprising, meeting Janet, this infinite database with the emotional calibration of a... well, Janet. There's a weird catharsis in seeing a being who can theoretically provide any comfort or simulate any scenario, trying to help someone whose pain is rooted in real, unchangeable violence. The fics that work best don't make Janet human; she's still parsing his trauma through her vast but oddly literal knowledge base.
Sometimes it leans into existential comedy—Janet trying to create a 'perfect guilt-free simulation' for him that hilariously backfires. Other times it gets dark, with Fang questioning if any peace she offers is real or just another program. The dynamic is less about romance and more about the mechanics of healing when one party is a walking, talking philosophical paradox. I'm not always convinced by the shipping aspect, but as a character study, it's a playground for asking if comfort built from nothing can ever be valid.
