Welcome back, Katie Cassidy!

Cassidy is returning to Arrow as a series regular in season 6, EW has learned. She will reprise the role of the Black Siren in the final two episodes of season 5 and will stick around for the following season. The news arrives almost exactly a year after Laurel Lance (a.k.a. Black Canary), Cassidy’s original Arrow character, was killed off in the April 6 episode “Eleven-Fifty-Nine”

“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,” said executive producer Marc Guggenheim in a statement. “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.”

The last time we saw the Black Siren, she was locked up in an A.R.G.U.S. facility after trying to kill Felicity (Emily Bett Rickards). At the time, Guggenheim teased that wasn’t the end for that character. “The episode ends with laying a very specific seed with a very specific game plan on our part that we hope to see come to fruition,” he told EW at the time. As of now, it’s unclear clear if and how this will affect the show’s current Black Canary, Dinah Drake (Juliana Harkavy), a metahuman with a Canary Cry who recently joined Team Arrow.

Ahead of her Arrow return, you’ll be able to see Cassidy in the season 2 finale of Legends of Tomorrow, which airs Tuesday, April 4.

Arrow airs Wednesdays at 8 p.m. ET on The CW.
