The old lady on the street always knew all of the gossip. From taking down Edie's husband to plotting on getting rid of Paul Young once again, she did whatever she had to do to keep Wisteria Lane as safe as possible. Her friendship with Edie was one of my favorite on the entire show, and I love her backstory with her son who passed away.
Obviously her most iconic moment was when she confessed to killing Gaby's stepfather to spare Bree from going to prison <3
