Katie Cassidy is set to return to “Arrow” in a full-time capacity for the upcoming sixth season. Cassidy portrayed Laurel Lance/Black Canary for the first four seasons of The CW series before being killed off late in the fourth season.
After she was killed, Cassidy signed a deal with the CW to appear across the DC universe portfolio of shows in a guest capacity. She reappeared as Black Siren, the villainous Earth 2 version of Black Canary, for a one-off in the middle of the current fifth season.
Cassidy will reprise that Black Siren role in the final two episodes of the CW show’s fifth season and become a regular for the sixth.
