Black Siren is bad to the bone, but she may not stay that way. The evil Laurel Lance doppelganger from Earth-2 had no qualms about battling Team Arrow in the Season 5 mid-season finale, but that facade began to crack towards the end of the season when she confronted the Earth-1 version of her father Quentin Lance. According to executive producer Wendy Mericle, that's an angle the show plans to explore.
“I don’t know if there’s any question about whether or not the [idea] of redemption will come up; it has to,” Mericle told TVLine. “Her father is there. Oliver is there. Everyone is going to be asking whether or not it’s possible to find a little piece of Laurel, the Laurel Lance they knew and loved, in there somewhere.”
Nevertheless, Mericle made it clear that she enjoys watching Laurel get in touch with her bad side. “I think she’s interesting as a [villain],” she said.
Katie Cassidy played Oliver Queen’s love interest Laurel Lance over the first four seasons of “Arrow.” In Season 3, she became Black Canary to honor her sister Sara, a former Black Canary who was murdered by Malcolm Merlyn. In Season 4, Laurel herself was killed by HIVE leader Damien Darhk.
Nevertheless, that wasn’t the end of Laurel. Her Earth-2 doppelganger Black Siren debuted in a Season 2 episode of The Flash. Unlike Earth-1’s Laurel, Black Siren is a metahuman with a super sonic scream and — instead of becoming a hero — she used her powers for evil, aligning with the evil speedster Zoom. When Zoom fell, she was imprisoned by Team Flash, only to be freed by Prometheus in a bid to torture Oliver.
Prometheus called her back to his side for the Season 5 finale. Indebted to him for rescuing her, she helped him capture all of Oliver's friends, though she expressed some remorse to Quentin Lance and revealed to him that it was hard for her to hurt him. Nevertheless, she joined Prometheus in the fight against Green Arrow. She was last seen on Lian Yu before it exploded; though it is unclear if she survived at this time, that seems likely thanks to Mericle's comments above, as well as the fact that she was upped to a series regular for Season 6.
Starring Stephen Amell as the Emerald Archer, Arrow returns Thursday, October 12 at 9pm ET/PT on The CW. The series also stars Emily Bett Rickards, David Ramsey, Willa Holland and more.
