Arrow’s Katie Cassidy is Coming to The Flash, But Not As You May Expect

Black CanaryMarc Guggenheim, executive producer of The CW’s Arrow, announced at a press screening yesterday that Katie Cassidy (Black Canary) will be seen on the final episode of The Flash this season. This won’t be the first time Katie has appeared on the show. Laurel Lance met with Cisco Ramon (Carlos Valdes) when he and Joe West (Jesse L. Martin) visited Star City. However, she’s not going to be quite the same this time around.

Casssidy will appear on an alternate Earth as Donna Nance (not Laurel Lance). In this Earth-2 version of Laurel Lance, Nance is codenamed the Black Siren. Details have not been revealed as to how she will interact, or come in contact, with The Flash and as soon as we receive any further breaking news on this episode or pics from the set, we will certainly update this article and keep you up to speed!


So who is the Black Siren? Here’s a brief bio courtesy of

Black Siren, along with the rest of the Justice Guild of America, died during a nuclear war. She was mentally “revived” by Ray Thompson, who missed his childhood idols.

Black Siren felt that, as the team’s only female member, it fell upon her to perform the household chores and duties. The fact that Siren went about her domestic duties with a smile on her face was doubly-disgusting to Hawkgirl, though Hawkgirl played along so the Justice League could find answers and get to the bottom of the case.

Black Siren is based on the Golden Age version of the character Black Canary, Dinah Drake. Originally debuting as a supporting character in a Johnny Thunder strip, Black Canary eventually became a member of the Justice Society. The second Black Canary, Dinah Laurel Lance, is her daughter. Unlike her daughter, she does not have the famed Canary Cry.
