Sophia, Dorothy's mom, wasn't supposed to be in every episode. She was slated to only make guest starring appearances, but that idea was scrapped when test audiences really took to the character. Therefore, Sophia was written in as a main character and made her first appearance in the pilot episode when her nursing home burned down. That plot line would continue to pop back up, with Sophia once believing she would be sent to jail for her role in starting the fire by making s'mores on an unauthorized hot plate in her room. The ladies of her house banded together to try to prove her innocence as well as consider how different their lives would be without Sophia's maternal, and sassy, presence.
