Spoilers follow for the Season 3 premiere of Arrow.
The finale to Arrow saw Sara, Laurel's sister, get killed by a mysterious individual, right in front of her.
In the comics, the real Black Canary is Dinah Laurel Lance, and obviously Arrow is following suit by having Cassidy's head sculpted to be fitted for a mask.
While we have yet to see Laurel in action, Katie Cassidy did recently star as a superhero in The Scribbler.
This is what I call chic. #NoFilter
