BIRDS OF PREY; CAITY LOTZ GUEST STARS
After being accused of murder and having her criminal past exposed, Laurel (Katie Cassidy) goes full Black Siren and teams up with an old criminal acquaintance, Shadow Thief (guest star Carmel Amit), to go on a crime spree around Star City. While Dinah (Juliana Harkavy) aims to bring Laurel in, Felicity (Emily Bett Rickards) refuses to give up on her friend and tries everything to get through to her, even summoning Sara Lance (guest star Caity Lotz) for help. However, Laurel rebuffs all her efforts, forcing the former friends to face off against each other.
In Arrow, after a violent shipwreck, billionaire playboy Oliver Queen was missing and presumed dead for five years before being discovered alive on a remote island in the Pacific. When he returns home to Starling City, his devoted mother Moira, much-beloved sister Thea, and best friend Tommy welcome him home, but they sense Oliver has been changed by his ordeal on the island. While Oliver hides the truth about the man he’s become, he desperately wants to make amends for the actions he took as the boy he was.
