Who is Edna from Stone Butch Blues and what is their importance?

Edna is Butch Jan's femme. Edna's departure from Jan breaks Jan's heart. When Jan says that Edna can seduce any stone butch love, it awakens Jess's sexual interest in Edna. At first, Jess can't get together with Edna - she feels she's too young, and she's concerned about how Jan will feel. Years later, after Jess starts taking hormones and drifts away from her old crowd, she meets Edna at a supermarket. Both of them are lonely, and they fall into each other's arms.
