Katie Cassidy Plays Black Siren In First Look Images From Next Week’s Episode Of The Flash

The CW has released the first images from next week’s instalment of The Flash, and it looks like Black Siren will be making her presence felt in a big way here. Played by Arrow alum Katie Cassidy, this villainous meta-human is one of Zoom’s closest allies and the Earth-2 doppelgänger of the recently departed Laurel Lance/Black Canary.

For more details on what to expect from this episode of The Flash, we have the synopsis for “Invincible” below, which provides a few more clues:

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.

Last night’s The Flash – directed by Kevin Smith – was arguably one of the best to date, and with a now much more confident Barry Allen in control of the Speed Force, it’s going to be interesting to see how he decides to approach finishing Zoom off once and for all.

That’s not the only question these images leave us with of course, especially as we see Killer Frost and Reverb, two characters who are supposed to be dead. Could Zoom have faked their deaths somehow? We’ll have to wait and see, but as The Flash races towards its finale, it’s clear that we have an awful lot to look forward to.
