This is the relationship between the witches Josette Parker and Olivia Parker. These two are sisters and members of the Parker Family and Gemini Coven. They are the daughters of Joshua Parker and an unnamed mother and the sisters of Jo's twin, Kai and Liv's twin brother, Luke. In the second half of season 6, Liv helps Jo re-learn magic to defeat Kai once and for all, however, their plan failed since Luke merged with Kai and died, making Kai the official leader of the Gemini Coven.
On January 5, 1991 Jo became a big sister to Luke and Liv. Jo was more like a mother to them since sometime after their birth their mom died of unknown causes. Despite knowing Liv was born to save Jo, she was close to her sister when Liv was still a toddler. However, after Kai murdered their siblings, and attempted to murder her, Luke and Liv and was thwarted by their father, Jo left home, seeking a normal life. Upon leaving, she left them with little memory of her and was estranged from them for 18 years.
