Only two episodes remain in The Flash Season 2’s immediate future, though next Tuesday will take us into the recent past with the return of several familiar faces. Not only will Laurel Lance live on as the Earth-2 Black Siren (amusingly photographed on an undoctored set), but even more deceased metahumans seemingly make the trip in our first photos.

Katie Cassidy’s Earth-2 Black Siren makes a formal debut in photos of next week’s “Invincible,” some of which might have forgotten to take the Canadian flag out of Central City (The Flash, like many shows, films in Vancouver). Perhaps most curiously, Killer Frost (Danielle Panabaker) and Reverb (Carlos Valdes) are back in action, likely a flashback to establish their dynamic with Black Siren.

So reads the synopsis for next week’s “Invincible”:


After Zoom (guest star Teddy Sears) unleashes an army of Earth-2 meta-humans on Central City, Barry (Grant Gustin) is shaken when he sees their leader is the Black Canary’s Earth-2 doppelganger, the Black Siren (guest star Katie Cassidy). Meanwhile, Wally (Keiynan Lonsdale) takes to the streets to help The Flash stop the meta-humans, which worries Joe (Jesse L. Martin). Iris (Candice Patton) and Henry (guest star John Wesley Shipp) are concerned about Barry taking on Zoom.

While we wait, check out the latest trailer again below, and stay tuned for more on the final Flash Season 2 episodes.
