Last night was the first of this week’s double dose of Katie, As she made a guest appearance on 4×19 – Fury Rogue of The Flash as Siren-X the Earth X version of Laurel who is by far more evil and bad ass then Black Siren at this time, I do love that they gave her a new power to go with the Sonic scream it was a Sonic radar or something like that so she could hear and tell when things were being said or coming at her, I did not like that she look’s exactly the same as Black Siren right all the others on Earth X had different costumes so why not her. The other thing is how the hell are they going to explain why Laurel was killing people in central City with a power when Earth 2 Laurel is trying to pretend Laurel with no powers or killing people, I don’t think the writers thought that through very well. And we don’t no what happens to her as the last we see she was knocked out so maybe we will see more of her some time next season?. HD creen captures are now up in the gallery and if you click read more you can watch some of the videos.

Well no one saw this coming but Katie will be in next week’s episode of The Flash as Siren-X the Earth X version of Laurel, who has the exact same costume as Earth 2 Laurel? you think the costume designers could do something new for her and why was she not in the crossover if as we now no there is a evil Laurel there. With thanks to Far Far Away for the HQ still.

Now this people is how you utilize Katie Cassidy in a TV show, She was badass and looked in charge do it. The Flash writers did a better job with Black Siren in one episode then the Arrow writers did her entire run as as Black Canary on Arrow. And the best part is she did not die so we could see her again down the line on The Flash or making her way onto Arrow, How good would it be to see her kick all there ass’s over there.

TVLINE | Speaking of Zoom’s many henchmen, does Cisco get to render an opinion on Black Siren (played by Arrow‘s Katie Cassidy in the May 17 episode)?
Carlos: Yeah, but it’s not the reaction that you’d think Cisco would have, because the wound of Laurel’s death is pretty ubiquitous in this DC TV universe. We see there’s an Earth-Two Laurel, a version of Laurel that’s alive, and that does things to somebody’s consciousness, especially after processing grief. There’s definitely a bit of shock there and difficulty grappling with reality

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.

Do you know anything about the episode of The Flash that Katie Cassidy will be guest-starring in on May 17th? —Jill
“Like most of the Earth-Two metahumans, Black Siren is under the thumb of Zoom,” EP Todd Helbing tells me. That said, “She’s a very powerful metahuman,” EP Aaron Helbing notes. “She is sassy, strong and capable…. Katie really nailed the performanc

More news about Katie’s upcoming The Flash episode has come out today, And why she will be playing Earth two’s Laurel Lance she will not be playing her Earth one’s version Black Canary but Black Siren. Black Siren who’s rea; name is Donna Nance, was a member of the Justice Society and the mother of Dinah Laurel Lance in the DC Comics canon, And has been in two episode’s of the show the Justice League when they were sent to the past only to find out it was not real, But was is a hero who love’s looking after her male team members. At this time we don’t no if Katie will take any of this on it her version of Black Siren, Or the name was used as it sounds like Black Canary the same way that Cisco was Reverb on Earth 2 and Vibe on Earth 1.

Arrow producers confirmed today that Katie Cassidy will be appearing on an upcoming episode of The Flash as the Earth-2 version of her character who is called “Black Siren” on the other world. The name may be different from “Black Canary” but there’s precedent for that, as “Black Siren” was the name of an analogue for the Golden Age Black Canary in the Justice League animated episode “Legends” written by The Flash’s own Andrew Kreisberg.

You will see her on an episode of The Flash playing the Earth 2 version of Laurel Lance.
