Laurel Lance, a.k.a. Black Canary, was killed off during Arrow season 4, but it wasn’t the end for actor Katie Cassidy. Arrow season 1 introduced viewers to Laurel Lance, the former girlfriend of Oliver Queen (Stephen Amell) who reconciles with the billionaire playboy following his five-year stint on the mysterious island of Lian Yu. In season 3, Laurel follows in her deceased sister’s footsteps and becomes a vigilante in her own right, known as Black Canary, a move that eventually strengthens the bond between her and Queen.
