Doppelgangers of characters we've already been introduced to have been present with viewers already meeting Earth-2 Barry, Caitlin and Ronnie amongst others and now, plans have been set in motion to introduce the Earth-2 version of Laurel Lance (Katie Cassidy).
Well known to the group, TVLine confirmed when speaking to executive producer Marc Guggenheim that Cassidy would be making a crossover to The Flash, appearing on the series as the Earth-2 version of Laurel, AKA Black Siren.
Fans know Black Siren as Donna Nance, a character from the animated Justice League series based on the Golden Age Laurel Lance of DC Comics. Though she fought crime in the animated series, it's possible she will be involved in The Flash's series as a villain.
Arrow continues tonight (April 6) at 8pm on The CW, with The Flash returning on Tuesday, April 19 at 9pm.
