Arrow executive producer Marc Guggenheim has said that Katie Cassidy (Laure Lance) will not only be returning for the final two episodes of this season, but she’s been confirmed as a series regular for season 6.
There’s a bit of a twist, as she will be playing Black Siren, Laurel’s Earth-2 doppelganger which first appeared late in season 2, Black Siren popped up again in Arrow’s midseason premiere back in January to stir up mixed emotions in Oliver Queen, to put it mildly. Although our hero tried to redeem her, she ultimately proved to be a force for evil, but the door was left open for her return.
Guggenheim said “One of the things that most excites us about is that we go where the story takes us. Last year, the story took us to the tragic death of Laurel Lance. This year, our midseason finale reintroduced us to Laurel’s doppelgänger, Black Siren. We were so taken by Katie’s fearless interpretation of this character that we knew her story was not yet finished. We couldn’t be more thrilled to welcome Katie back to as Black Siren, though as her appearances on and this season show, she never really left the family.”
