It’s a gathering of all the canaries on a new episode of Arrow.

Arrow episode 718, “Lost Canary,” will see Laurel up to her old tricks as Black Siren with two canaries hot on her trail for different reasons.

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.

Arrow episode 718 airs on April 15, 2019.
