Sold her soul to Satan and all she gets is a crappy manager position at a burger joint. Her demon takes control and it will be like this for her from now on. Witches are from every race, gender, age. Only regional background determines which branch of the satanic order they hail from.
In this case, as in most, you can clearly see she is working with the emerging demon by using her satanic skills she has learned from her mother and Aunt. Until the demon assumes full control and does what it does - it wants to destroy the vessel that holds the Light of someone whose name is found in the Book of Life.
