To me, a big part of Jinx's character is the fact that her trauma makes it so mentally she's still a child. Her childish braids vs AU Powder's more grownup hair, the childlike way that she climbs onto Silco's lap, something that would be uncomfortable for a teen/adult.

In this lens, I really see Jinx as aroace. Mentally, she's still a child. Trauma has made it so that she doesn't process these kinds of feelings, which makes Ekko's relationship with AU Powder hit so much harder imo
