Watch Arrow season 7, episode 18 trailer

Black Siren makes a comeback and Sara Lance returns in the next episode of Arrow. But before they do, check out the brand new trailer for “Lost Canary”.

With its Season 7 finale in sight, Arrow is pulling out all the stops. Following the previous episode’s flash-forward-heavy adventure, this week’s outing gave us more of an insight into the Emiko Queen situation, revealing that not all was what it seemed when it came to Oliver’s newfound sister. One character that also featured heavily in the episode was Earth-2’s Laurel Lance/Black Siren, and it looks like she will be set to steal the show in Arrow‘s next installment.

Unfortunately, the show is set to take one last extended hiatus and won’t return to our screens until mid-April. But fear not, because The CW has released a brand new trailer for the upcoming adventure which will undoubtedly leave you wanting more. Check it out below:

The episode, titled “Lost Canary”, will see the return of Arrow vet and current Legends of Tomorrow headliner Caity Lotz as Sara Lance in what has been billed as a Birds Of Prey-centric episode, focusing on Laurel, the returning Sara and current Black Canary Dinah Drake.

After Emiko Queen leaked pictures of Laurel’s time with Diaz to the public, it seems that Star City will begin turning on their beloved District Attorney. This will take her back down the dark path as she resurrects her Black Siren persona to go on an all-out war against the city.

When her new allies Felicity and Dinah are unable to get through to her, this ends up forcing Team Arrow to reach out to someone who can: Sara Lance a.k.a. the White Canary, and sister of Earth-1 Laurel.

Will these Canaries be able to stop Laurel from resurrecting her formerly evil ways? Or will Black Siren reign supreme once more?
