yssa Al Ghul (guest star Katrina Law) returns to Star City to warn Thea (Willa Holland) that a group of renegade League of Assassins members are planning to attack her.

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.
