- "It's the Arrow who matters, The Man Under the Hood isn't important."
- —Quentin explaining to laurel why he doesn't want to know The Arrow's Identity
Oliver, Sara, Diggle and Felicity return to the lair and find Slade waiting for them. An epic battle breaks out and one member of Team Arrow is sent to hospital – his battle with Slade or his family. Meanwhile, Laurel struggles with a new secret.
Oliver and his team break into the Applied Sciences division of Queen Consolidated and destroy the lab so that Slade does not have access to it to mass-produce the Mirakuru. Laurel went to visit Quentin and ask her about The Arrow and the woman in black, just right, Sara walks in. Queen's lawyer tells Oliver and Moira they will be broke unless all three of the Queens sign the trust fund. Moira ask Oliver to convince Thea to sign the trust fund so that they can fight back.
In response of the bombing, Slade attacks the team at their hideout and steals the "Skeleton Key", so that he can access any lab to get the equipment he needs. Sara went to the hospital with excuse of "motocycle accident" and Laurel came to check on her. Laurel saw the scars on Sara back and starts to piece together that she might be the woman in black who rescued her. Thea refused to sign the trust fund with the reason she is not Robert's daughter but Malcolm. The team is too late and Slade successfully steals a bio-transfuser that will allow him to transfer his Mirakuru-infused blood to the convicts he freed. Felicity had some brief chat with the staff and as well as talking about Barry still in a coma as they know him too. Quentin was beat up by a convict in jail due to him being a cop. Oliver tracks Slade and discovers that he has kidnapped Roy and is using him to transfuse the blood. Oliver rescues Roy, and Isabel is mortally wounded in the battle. Later, Oliver reveals there is a cure for the Mirakuru, and Felicity goes to S.T.A.R. Labs to have an antidote created. Meanwhile, Laurel investigates Oliver being the Arrow, which leads her to discover that Sara is the Canary. Laurel stops her investigation when her father tells her that the Arrow's identity is irrelevant to the symbol that he represents. Laurel later blackmails her supervisor into releasing and reinstating her father. Slade's army of Mirakuru warriors gather and Slade uses his own blood to heal and empower Isabel as well. In flashbacks, Oliver kills Ivo at his request, in exchange for telling him and Sara about the Mirakuru cure.
