After tonight's "Go To Hell" episode of American Horror Story: Coven, FX released a sneak preview of episode 13, which is called "The Seven Wonders." In "The Seven Wonders" episode, a new Supreme rises in the Season 3 finale. American Horror Story: Coven tells the secret history of witches and witchcraft in America. Over three hundred years have passed since the turbulent days of Salem and those who managed to escape are now facing extinction. Mysterious attacks have been escalating against their kind and young girls are being sent away to a special school in New Orleans to learn how to protect themselves. Wrapped up in the turmoil is new arrival, Zoe, who is harboring a terrifying secret of her own. Alarmed by the recent aggression, Fiona, the long-absent Supreme, sweeps back into town, determined to protect the Coven and hell-bent on decimating anyone who gets in her way.
