The CW has released the first photos of Katie Cassidy as Black Canary -- not "Canary," like her sister Sara, but officially billed as full-on "Black Canary" -- in the upcoming "Arrow" episode "Left Behind," scheduled to run as the 10th installment of the currently unfolding third season.
Cassidy's Laurel Lance taking on the Black Canary mantle is a natural progression -- the character (full name Dinah Laurel Lance) shares a name with long-running DC Comics superhero Black Canary, and though she hadn't previously taken on a costumed identity, there's a Canary-sized void in the Lance family following developments earlier this season. In recent episodes, she's been training with Ted Grant (played by J.R. Ramirez), and moving towards her own vigilante role.
"Arrow" airs 8 p.m. Wednesdays on The CW. Based on the show's current schedule, "Left Behind" will likely air in early 2015.
