Fan favourite and all around badass Katie Cassidy looks set to be returning to the cast of Arrow as earth two Laurel Lance, Black Siren.
Her return to the Flarrowverse has been slow with moments passing through the Flash, Arrow and now Legends of Tomorrow. The scene with Laurel and Sara Lance proving to be one of the more emotional points of the season finale could have spent into something more…
Marc Guggenheim, Legends of Tomorrow EP talked to Vulture her almost joining the Waverer crew:
We briefly spoke about bringing her on “Legends,” but I think from a story perspective we would get far more mileage out of her interacting with the cast of “Arrow.”
It’s rumoured that Black Siren will be the main villain for the next season of the Arrow so maybe she’ll pull a Snart/Rory and join the crew as a reformed villain.
