She was struck by the Grady curse, and her parents were slaughtered trying to save her. Like Grubbs, she calls herself Gret because her real name is terrible. When Grubbs plays a practical joke on her, involving rat guts in her towel- she first shows some indication that she is struck by the curse. It was originally Dervish's job to partner up with Cal if in case one of Cal's children were to succumb to lycanthropy. However, Sharon's intervened and fought instead so Dervish was not called. Cal and Sharon had died as a result in trying to cure Gretelda.
She is mentioned by Grubbs along with her parents.
She appears in Grubbs's nightmare.
