Get ready for more mini-Berlantiverse crossovers.
Arrow‘s Katie Cassidy is heading to The Flash for this season’s penultimate episode. “You will see her on an episode of The Flash playing the Earth-2 version of Laurel Lance,” Arrow EP Marc Guggenheim revealed at a press screening on Monday. On Earth-2, Laurel actually goes by Black Siren, the DC Comics superhero.
Cassidy will also lend her voice to the animated Flash-Arrow spin-off Vixen as Earth-1 Laurel Lance in season 2. As you may recall, when Megalyn E.K. brought Mari McCabe to life on Arrow, the heroines seemed to already know each other.
The Flash airs Tuesdays at 8 p.m. ET, while Arrow airs Wednesdays at 8 p.m. ET on The CW.
