Katie Cassidy has shed some light on the backstory for Black Siren on Arrow. After the death of Laurel Lance (Cassidy) in Arrow season 4, fans may have thought that Cassidy would be bowing out of the show entirely, or just appearing for the occasional flashback. It was a heartbreaking moment for fans of the character, even knowing that a new Black Canary would be on the way soon. However, the show hasn’t lost Cassidy entirely. Instead, the Arrowverse has taken advantage of the multiverse introduced in The Flash to bring the actress back as Laurel’s evil doppelganger from Earth-2: Black Siren.
Black Siren played a big role during Arrow season 5, after Prometheus broke her out of her Central City prison in order to help him defeat Oliver Queen (Stephen Amell). And while it was fantastic to see this new, evil version of Laurel get some real screen time, the character’s backstory is still mostly a mystery. Now, Cassidy herself has given fans a little more info on who Black Siren is, thanks to a question from a co-star at Heroes and Villains Fan Fest.
The convention took place over the weekend in London, England, and many of the Arrowverse stars were there. In a panel alongside Josh Segarra and Emily Bett Rickards, Cassidy was asked about her new character’s history on Earth-2 – and while she didn’t go into too much detail, she definitely fleshed out some of the Black Siren’s relationships for the audience (starting at 17:35 in the video below):
Emily Bett Rickards: So, Black Siren, when she comes over from the other universe, she still has Lance as a father and Sara as a sister? Or is she in a universe where she doesn’t have Sara?
Katie Cassidy: So, she does, she has on Earth-2, all you guys play a role, but a different… you look the same in the flesh, but not necessarily I don’t think are you going to be like, he is my father on Earth-2 but is a different person to me. And same with my, well, Black Siren’s boyfriend looked like Oliver but was different internally.
Now we know that there are some more doppelgangers waiting in the wings, although there’s no way of knowing if or when the other members of the Earth-2 Lance family will make an appearance. Black Siren’s past is also something that could be explored more fully in season 6 of Arrow, especially if her story is going to involve a redemption arc and a potential reclaiming of the Black Canary name. This is all speculation for the moment, however, so fans will have to wait until the new season starts in the fall to find out what the show has in store for the new version of Laurel Lance.
Arrow returns to The CW this fall.
