Elizabeth is part of a coven of witches with her friends Amanda, Tammi, and Renee. She is gifted at gardening and grows rare herbs in her garden.
Background
She is first seen while she is tending to her garden and notices Amanda going to her house. She attempts to speak to Amanda about book club, but Amanda politely tells Elizabeth that she is busy. After Amanda's death, Sam and Dean approach her and question her about Amanda and all the satanist stuff she had her in house. Sam also comments on the rare herbs she is growing. While talking about it, Elizabeth begins to show signs of being nervous, but is saved by her friends.
Later in the evening, the ladies are having book club at Renee's house. They are using magic to lower her husband's mortgage. In fact, a lot of her accomplishments were done this way. Then Sam bursts in telling them to stop, and points a gun at them. Tammi reveals herself to be a demon, and Elizabeth is shocked. She does save Sam and Dean later when she uses magic to make pins stab in Tammi's throat. The demon responds by effortlessly killing her.
