EW – Arrow‘s original canary is coming home (at least for an episode).

EW has confirmed that Legends of Tomorrow star Caity Lotz — who originally played Sara Lance/Black Canary on the show before becoming Legends‘ White Canary — will appear in season 7’s 18th episode “Lost Canary.” As of right now, it’s unclear how involved Lotz will be in the episode; however, TVLine reports that the hour is inspired by the Birds of Prey, DC Comics’ female vigilante team, and will also involve Black Siren/Earth-2 Laurel (Katie Cassidy Rodgers). (It’s worth noting that this should not be confused with the Arrow season 2 episode “Birds of Prey.”)

Cassidy Rodgers shared a behind scenes photo Thursday featuring herself, Lotz, and a masked Juliana Harkavy, who plays Dinah Drake/the current Black Canary. “Girls rule #round2,” she captioned the team-up photo.

Obviously, this won’t be Lotz’s first appearance on Arrow this year. She made a very brief cameo in the superhero drama’s documentary-like 150th episode. Before that, she appeared in the season 6 finale, which saw Sara meet her sister’s Earth-2 doppelgänger when she returned to see her father Quentin (Paul Blackthorne) before he died.

The 150th episode of “Arrow” showcases a documentary entitled “The Hood and the rise of vigilantism” starring Oliver Queen (Stephen Amell), Felicity Smoak (Emily Bett Rickards), and the rest of Team Arrow.

THE TEAM IS TARGETED — Oliver (Stephen Amell) and Felicity (Emily Bett Rickards) are disappointed after they learn that William (guest star Jack Moore) is hiding something from them. Wanting to focus on his family, Oliver steps back from his Green Arrow duties and let’s the team take over tracking down a serial killer. However, when the team becomes targets for the killer, things take a bloody turn.

AT LAST IT’S HAPPENING not only will we at last get to see Laurel’s backstory but get to find out if her redemption arc is real or not and on top of that she will play a big part in a Birds Of Prey episode.

Tvline – The back half of Arrow Season 7 has plans for ADA Laurel Lance above and beyond her giving Oliver side-eye during his TV news program appearances.

As Arrow showrunner Beth Schwartz revealed as part of TVLine’s in-depth midseason preview Q&A, “We are doing a Birds of Prey-inspired episode, that Laurel (played by Katie Cassidy) will be involved with.”

The famously spoiler-averse Schwartz left the tease at that, other than to invite viewers to speculate as to who might join Laurel on that team-up. (In the comic books, the actual Birds of Prey is typically comprised of Black Canary and Oracle/Barbara Gordon, plus a rotation of other female superheroes. The short-lived 2002-2003 TV series featured Oracle, Dinah Lance and Huntress.)

In addition to the above — as well as an episode that will shed light on this Laurel’s Earth-Two backstory — Schwartz said, “We’ll get to see what happens in her overall redemption arc — whether she really did turn over a new leaf, or is she still the same evil Black Siren we met last season.”
