SEASON 2 – EPISODE 23
The cure works and Oliver and his team must escape their hideout when Slade’s men arrive. Back at Verdant, Sara arrives with Nyssa and the League of Assassins to provide backup to take out Slade’s men. Equipped with the cure, the team confront Slade and Isabel at Queen Consolidated. Nyssa kills Isabel, but Slade manages to escape.
Meanwhile, Diggle and Lyla go to A.R.G.U.S. to force Waller to stop the nuclear strike on the city. Laurel is abducted from police HQ and Quentin is seriously injured. Thea meets up with Roy, but when she finds a bow and quiver she loses trust in him and decides to leave Starling City with Malcolm.
Oliver and his team successfully use the cure on all of Slade’s men. Oliver tricks Slade into kidnapping Felicity, believing she is one Oliver loves. With Slade distracted, Felicity injects him with the cure. Oliver is able to defeat him and Waller calls off the bombing. Slade is locked away in an underground A.R.G.U.S. prison on the island and Sara rejoins the League as payment for helping the city.
In flashbacks, Anatoli fires a torpedo into the Amazo, causing it to sink. During the destruction, Oliver presumably kills Slade and Sara disappears overboard. Later, Oliver awakens in Hong Kong, where he meets Amanda Waller.
