Katie Cassidy Is Returning As A SERIES REGULAR For Arrow Season 6

Big news for fans of Earth-2’s Laurel Lance: Katie Cassidy has been signed as a series regular for the upcoming sixth season of Arrow — and we’re going to see her back again before then, with the actress appearing in the final two episodes of Arrow Season 5 as the Black Siren.

“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,” Executive Producer Marc Guggenheim said in a statement.

Stephen Amell himself expressed interest in continuing the Black Siren story in our PaleyFest interview last week. “I thought that the arc that we did with Katie Cassidy and Black Siren was awesome, and I would love to see more of that,” he said.

It will be interesting to see what Cassidy’s return does for the series — especially with a new Canary-like character in Dinah Drake. Hopefully Juliana Harkavy will be sticking around as well, and we will get to see how that plays out.
