H.I.V.E. continues to attack parts of the city, most recently destroying money meant for the city bank. Diggle gives Oliver information that H.I.V.E. murdered his brother Andy because he was criminal competition. The team heads to the research lab to locate a chemical they believe is being used by H.I.V.E. The team is attacked by Darhk's group, and Diggle discovers that Andy is still alive and working for H.I.V.E. The team tries to get Diggle to recognize the positive, but he refuses to see Andy as anything more than a traitor and unworthy of saving. The team believes Andy is being mind-controlled and locate him and the rest of H.I.V.E. The team successfully extracts Andy with help from Ray and his ATOM suit. After an encounter with Darhk, Thea learns that his powers may help cure her bloodlust permanently, after Darhk failed to drain the lifeforce from Thea.
