Initially pretending to comfort Thea after her breakup, Slade uses his opportunity to kidnap her. Distracted by Thea's kidnapping, and having his team work to locate Slade, Oliver gives temporary CEO status to Isabel Rochev so that she can ensure that the company runs smoothly in his absence. Isabel uses her temporary power to convince the board of directors to make her position permanent, thus allowing her company to take full control over Queen Consolidated. When confronted, Isabel reveals that she has been working with Slade the entire time, and tells Oliver where Thea is being held. Oliver arrives, but Thea has already been freed—her kidnapping was a diversion from Slade's real plan to free a group of convicts to be used as test subjects for the next Mirakuru trials. Thea informs Oliver and Moira that Slade told her that her biological father is Malcolm Merlyn. Quentin Lance is arrested for aiding the vigilante, Roy leaves Starling City, and Slade visits Laurel and reveals that Oliver is the Arrow. In flashbacks, Sara attempts to use the trade for Oliver as a moment to kill Slade, but it backfires.
