Complete story — includes the ending
As Slade's army continues to terrorize the city, Felicity and Diggle outwit Isabel and escape. S.T.A.R. Labs finishes the Mirakuru cure, but Slade sends men to acquire it before Oliver. Finally trusting Quentin, the police force pledges to help the Arrow stop Slade's men and Quentin is reinstated to lead them. Slade reveals to Blood that he plans to destroy the entire city, people and all, in his quest for vengeance against Oliver. As a result, Blood steals the cure and gives it to Oliver in return for help saving the city. For his betrayal, Slade has Isabel kill Blood. Oliver tests the cure on Roy after Amanda states that she intends to bomb the city at dawn to prevent Slade's men from attacking the rest of the country. Meanwhile, Sara returns and saves Laurel, who gives her the alias "Canary". Malcolm saves Thea from an assailant and tries to convince her to leave with him, but she shoots him. In flashbacks, Oliver boards the Amazo to rescue Sara, who was captured by Slade, with specific orders for Anatoly to destroy the ship if they do not return within an hour. However, they are both captured by Slade.
