The Flash 2.22 Official Description: Katie Cassidy Guest Stars!

[Disclaimer: this post does feature big spoilers from Arrow 4.18 “Eleven-Fifty Nine”]

The Flash Season 2 is approaching its end with only a few episodes left leading up to the season finale that will air on Tuesday, May 24. A few weeks ago on Arrow, we saw the tragic death of Dinah Laurel Lance a.k.a. the Black Canary and while the Earth-1 version may be dead, that is not the case for Laurel on Earth-2. It was recently announced that Katie Cassidy would be guest-starring on The Flash as the Earth-2 version of Laurel Lance who in that world goes by Black Siren.

Today we got some more details on that as The CW released the official description for the 22nd episode of Season 2 titled “Invincible” which will air on Tuesday, May 17. According to Kevin Smith, who directed episode 21 “The Runaway Dinosaur”, said recently at Hollywood Babble-On that we are getting a 2-parter with episode 22 and 23 so this episode will be heavily tied with the season finale. Check out the full description below, but be aware of some potential spoilers.

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 (FL222). Original airdate 5/17/2016.

Black Siren made her debut in Justice League Unlimited in two-parter titled “Legends” which was written by The Flash’s executive producer and show-runner Andrew Kreisberg. Those episodes featured the Justice Guild, that was the show’s take on the Justice Society of America and Black Siren (whose real name is Donna Nance) was based on the Golden Age version of Black Canary (Dinah Drake who was the first one).

The Flash airs on Tuesday nights at 8/7c on The CW. Are you excited to see Katie Cassidy appearing on The Flash as Earth-2 Laurel Lance a.k.a. the Black Siren? Let us know in the comments below!
