Complete story — includes the ending
In flashbacks, the Amazo sinks as Oliver planned. He presumably kills Slade while Sara disappears overboard. Later, Oliver awakens in Hong Kong, where he meets Waller. In the present, the cure works on Roy. Sara arrives with Nyssa and the League to provide backup for Oliver, who gives Roy a red mask. They confront Slade and Isabel at Queen Consolidated. Nyssa murders Isabel and tells Oliver he needs to kill Slade, who escapes. Meanwhile, Diggle and Lyla free the Suicide Squad members and enlist their help in stopping the drone strike. Quentin is seriously injured. Thea meets up with Roy but, when she finds a bow and arrow, she loses trust in him and leaves Starling City with Merlyn. Oliver and his team successfully heal all of Slade's men. Oliver tricks Slade into kidnapping Felicity, believing she is Oliver's love. With Slade distracted, Felicity injects him with the cure. Oliver defeats Slade and Waller calls off the strike. Slade is locked in an underground A.R.G.U.S. prison on the island and Sara rejoins the League as payment for helping the city. Lyla is revealed to be pregnant by Diggle. Quentin collapses as a result of his injury.
