Katie Cassidy just did an interview today where she talked about Black Siren. She said that if anything, she and the writers would want Black Siren on Legends of Tomorrow. Not Arrow. She says that it would create a very interesting dynamic with Sara and I do feel like Black Siren would be a better fit of there. Since Siren has powers, it would be better to keep her away from Arrow, which is going back to be more grounded and realistic. It also makes more sense. Her sonic scream is very powerful and could be useful in many situations, and a Rip likes to give people a shot for rehabilitation. Plus, if anyone saw Earth-2 Laurel hanging around Star City, they would have some questions as to why their dead hero / a.d.a is walking around. I say keep her on the Waverider and create a new, interesting dynamic with Sara. (Heck, they can even call her Dinah. Avoid confusion with Earth-1 Laurel and honor the comics. It's a win win in my opinion).
