Mrs. Lehane was the late mother of Faith Lehane. According to her daughter, she used to call Faith her "little firecracker" because of how energetic she was. As a child, Faith begged her mother to get her a dog, but her mother never did because she was too busy "enjoying the drinking and passing out parts of life" (in Faith's words).

Mrs. Lehane apparently died at some point before Faith's arrival in Sunnydale as Faith once proclaimed "My dead mother hits harder than that!" while fighting a vampire.
