Edna is a teacher at Springfield Elementary. Most of her problems include her love life. She dates various people. She dated Bart Simpson for a bit, if you can call it dating. Bart simply created an imaginary man and wrote letters to her. Through the years she has been seen with Moe, but her main man is Seymour Skinner. They had a relationship. They dated for years, got engaged, but broke up. Edna lives alone with her one cat, name pending, in an apartment. She’s a tad smart, and knows how to use her sexual power. We often find her revealing her body in one way or another.
She married Ned Flanders, years after leaving Skinner, in season 23. In 25, she died (her voice actor, Marcia Wallace, died first). It wasn`t shown in any episodes, but two small tributes were given to Edna, in her final season.
