Will her friend or dead doppelganger's sister get through to Arrow's Earth-2 Laurel Lance/Black Siren (Katie Cassidy)? Or is she "lost" forever to the side of evil? New photos released by The CW for Episode 18 showcase the female characters, both in the present and flashforwards.

Following Emiko (Sea Shimooka) revealing Laurel's criminal past to the world, the Earth-2 doppelganger "goes full Black Siren" and reconnects with her former criminal acquaintance, Shadow Thief (guest star Carmel Amit).

The actress announced her departure on social media.

Though Dinah (Juliana Harkavy) is focused on bringing in the (former?) villain, Felicity (Emily Bett Rickards) reaches out to Sara Lance (guest star Caity Lotz) in hopes she can help. But will that work, or is "Lost Canary" the end of Felicity and Laurel's friendship?

Also seen in the photos is a look at the team in the future — Felicity, Dinah, Mia Smoak/Blackstar (Katherine McNamara), and Zoe Ramirez (Andrea Sixtos) — continuing the fight to save Star City in 2040.
