After eight long seasons, Arrow is finally coming to an end. Naturally, the final few episodes will tie up a few remaining plot threads, such as revealing which Laurel Lance survived the "Crisis on Infinite Earths" special.
In an interview with Variety, Arrow show runner (and executive producer of the Arrowverse as a whole), Marc Guggenheim revealed his answer. The interviewer asked, "For a character like Laurel (Katie Cassidy), whose Earth-1 Laurel was killed and has been playing Earth-2 over the past few years, which version is left?"
Guggenheim replied, "Certainly the question of which Laurel is left is going to be answered very definitively in ["Arrow's"] Season 8 Episode 9. But the explanation for the result is given very strong in Episode 10. We went into the crossover knowing we would end with the combing of the Earth, and the reboot of the universe."
Arrow stars Stephen Amell as Oliver Queen, David Ramsey as John Diggle, Rick Gonzalez as Wild Dog, Juliana Harkavy as Black Canary, Katie Cassidy as Black Siren, Katherine McNamara as Mia Smoak, Joseph David-Jones as Connor Hawke and Ben Lewis as William Clayton-Queen. Arrow’s final episode will air Tuesday, Jan. 28 at 9 p.m. ET/PT on The CW.
