The Saltzman twins are the last remaining members of the powerful Gemini Coven. They are ideal representatives of the sign of Gemini, a mutable air sign known for its duality, chatty personality, and quick mind. Lizzie (Jenny Boyd) and Josie (Kaylee Bryant) are complete opposites. Lizzie is extroverted, sassy, and blonde, while Josie is introverted, sweet, and brunette. They have a complicated relationship because, someday, they will have to complete the merge, and only one will survive. They love each other so much that this reality is impossible to face.
While Lizzie is a bully in the first couple of seasons, she grows and learns to control her temper and her magic later in the series, embodying the light twin. Josie, the sweet goody-goody twin, represses her shadow content and negative feelings so thoroughly that when she is tricked into doing dark magic in Season 2, her darkness takes over, leading to her embodying the dark twin. Geminis are naturally dualistic. The trick for this sign is to strive for balance while not rejecting or ignoring their dark side, thus giving it more power.
As a mutable sign, Geminis are known for being spontaneous, open-minded, and indecisive. Lizzie certainly can’t decide who she wants to date, and you never know what she will do next. Meanwhile, Josie is open-minded, accepting people for who they are. Air signs like Gemini are all about communication, something we see reflected in both Saltzman twins. Lizzie and Josie are opinionated, talkative, and think on their feet.
