The Flash: Barry Allen Fights Black Siren… and Loses (Sneak Peek)

Katie Cassidy as Black Siren on 'The Flash'

Going in to tonight’s episode of The Flash, this clip will probably not be encouraging.

Barry Allen (Grant Gustin) meets Black Siren (Earth-2’s Laurel Lance played by Katie Cassidy) after she’s apparently destroyed Mercury Labs’ building with her sonic scream, er, siren. They, predictably, get into a fight.

And, Barry, um, gets his ass kicked.

THE FLASH: “INVINCIBLE”

KATIE CASSIDY GUEST STARS AS BLACK SIREN

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.

Jesse Warn directed the episode with story by Greg Berlanti & Andrew Kreisberg and teleplay by Brooke Roberts & David Kob (#222).

The Flash airs Tuesdays at 8pm EST on The CW.SuperFable
