The Flash: Katie Cassidy's Black Siren Teams Up with Earth-2 Villains in New Promo and Photos
Sadly, Black Canary is no longer with us, but that doesn't mean Katie Cassidy is leaving the Arrowverse anytime soon. A new promo and photos from the upcoming episode of The Flash, "Invincible," show Cassidy's Black Siren in all of her villainous glory:
In "Invincible," Laurel Lance's Earth-2 counterpart, Black Siren, teams up with the evil twins of Caitlin Snow and Cisco Ramon, known as Killer Frost and Reverb, respectively. But funnily enough, both of these characters have been killed, which must either mean that the episode includes flashbacks, or that resurrecting Earth-2 villains is a part of Zoom's plan to raise an army of metahumans.
Here's the official synopsis for the episode, which airs on Tuesday at 8pm:
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.
