Ironically, the fact that Katie and Sadie did so little is part of what makes them popular to fanfic writers. They got so little development on the show that fanfic writers have a lot of room to run with them--sometimes to the point of making them OC stand ins--without making them blatantly out of character. (Although that doesn't stop some fanfic writers from making them blatantly out of character anyway.)
