Katie Cassidy is staying on The CW. Deadline reports the actress has been promoted to series regular for season six of Arrow.

Cassidy originally played Laurel Lance on the DC Comics drama. When that character met her tragic end in season four, Cassidy continued on the series as Laurel’s doppelgänger, Black Siren. The show’s cast also includes Stephen Amell, Willa Holland, David Ramsey, Paul Blackthorne, Emily Bett Rickards, Echo Kellum, Josh Segarra, John Barrowman, and Colton Haynes.

The CW has already been renewed Arrow for a sixth season.

From Arrow EP Marc Guggenheim:

One of the things that most excites us about Arrow 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 Arrow as Black Siren, though as her appearances on Arrow and DC’s Legends of Tomorrow this season show, she never really left the family.”

What do you think? Do you watch Arrow? Are you glad Black Siren will stick around for season six?
