Oliver tells Thea he is going to die and that he is here to investigate Mar Novu. Oliver leads them to Talia al Ghul, who says there could be records of Novu in her father's records. Once they arrive at the catacombs, Talia finds an artifact that could lead them to the records before Athena shows up and they are forced to flee. They figure out that the records are at the top of the mountain. Talia betrays them and starts to climb the mountain herself, with Oliver and Thea tagging close behind. While Oliver incapacitates Athena and her group, Thea and Talia fight for the journal, with Thea winning. Oliver figures out that the impending crisis is being caused by Novu before saying goodbye to his sister and asking if Talia wishes to join a team known as the "League of Heroes." Meanwhile, in Hong Kong, John Diggle and Lyla Michaels track down criminal Farzad Qadir, the son of Ghloem Qadir, who is holding Ben Turner's wife Sandra Hawke and son Connor hostage in Kasnia.
