Complete story — includes the ending
Slade kidnaps Thea. Oliver gives temporary CEO status to Isabel in his absence and later reconciles with Moira. Isabel uses her momentary power to convince the board of directors to make her position permanent, thus allowing her company to take full control of 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 released—her kidnapping was a diversion from Slade's real plan to free a group of convicts to use as Mirakuru test subjects. Thea confronts Oliver and Moira, saying that Slade told her that her biological father is Malcolm. Quentin is arrested for aiding the Arrow. Roy leaves Starling City. Polls show Moira's chance of winning the election has increased. Isabel tasks the company's scientific division with working on Mirakuru. Slade, now an announced fugitive, 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 fails. A hallucination of Shado convinces Slade to spare Oliver and Sara, leaving Ivo with them on the island.
