The CW has released the Official Synopsis of Arrow episode “Elseworlds – Part 2” (7.09), to be aired on Monday, December 10 at 08:00-09:00 PM.
THE ELSEWORLDS CROSSOVER CONTINUES IN GOTHAM CITY WITH BATWOMAN (RUBY ROSE)
With Oliver (Stephen Amell) and Barry (guest star Grant Gustin) still stuck in the other’s bodies, the two get a lead on John Deegan (guest star Jeremy Davies) and head to Gotham City with Supergirl (guest star Melissa Benoist) to figure out why their reality has changed. While there, they meet the mysterious Kate Kane (guest star Ruby Rose) who provides them with information that leads the group to Arkham Asylum.
In Arrow, after a violent shipwreck, billionaire playboy Oliver Queen was missing and presumed dead for five years before being discovered alive on a remote island in the Pacific. When he returns home to Starling City, his devoted mother Moira, much-beloved sister Thea, and best friend Tommy welcome him home, but they sense Oliver has been changed by his ordeal on the island. While Oliver hides the truth about the man he’s become, he desperately wants to make amends for the actions he took as the boy he was.
