## Plot

When a masked thief with superhuman strength steals a centrifuge from Queen Consolidated, Central City crime scene investigator Barry Allen arrives to help the investigation. Later, he reveals that he is searching for super-powered beings in the hope that he will find the murderer of his mother, and exonerate his father for the accusation. In addition, Barry is also a fan of the Arrow's exploits. Oliver realizes that the thief was enhanced using the same serum that Ivo was searching for. Roy starts helping Sin to find her missing friend, who was a failed subject of Blood's experiment. Oliver shoots Roy in the leg to prevent him getting further involved. Oliver tracks the thief, revealed to be Cyrus, but is injected with an unknown toxin. In order to save Oliver's life, Felicity reveals his identity to Barry to help find an antidote. Meanwhile, Merlyn puts pressure on Moira to tell the truth to Thea. Moira instead contacts Ra's, who wants to kill Merlyn for breaking the League's code by destroying the Glades. As a result, Merlyn leaves. In a flashback to the island, Oliver and Shado find the serum, but when they inject it to Slade without the required sedative, his heart stops, just as Ivo arrives with his men.
