It’s unclear if she will portay a witch of something else, but it is clear that she will have something with Misty Day (Lily Rabe) because, everybody knows, she has an obsession with Stevie’s voice & Fleetwood Mac’s music.
Lily Rabe revealed that she is obsessed too with Stevie & that will be an honor to act with her. So, what do you think, Stevie Nicks will portray a witch or something else? What will be her story? And most important, what Fiona will do? I think that this picture summarizes her personality & her reaction.
If you don’t know Stevie & her music, I would recommend you to listen to her voice in this song, “Sara” from the album “Tusk“, one of the best from Fleetwood Mac.
