Katie Cassidy Shows Off her “Cry” in New The Flash Sneak Peek

A second sneak peek from tonight’s (May 17) episode of The Flash has been released. In the sneak peek, we get our first glimpse of Katie Cassidy as the Black Siren.

Entitled, “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.”

This is a canary cry I have been waiting for!! Too bad it happened on the wrong show!
