'Arrow' Season 4 Spoilers: Episode 3 Synopsis Released; 'Restoration' Promises The Return Of Three Characters, New DC Comics Villain

A new player is coming to Star City in “Arrow” Season 4, episode 3, as the major group splits for two very separate, yet important, adventures. Oliver Queen (Stephen Amell) and half of Team Arrow will have to battle yet another meta-human that’s threatening to do some serious damage to the city on behalf of the principal Season 4 bad guy.

According to TV Guide, Damien Darhk (Neal McDonough) and the villainous organization known as HIVE will hire a new type of mercenary to try and stop Queen and his partner Diggle (David Ramsey), while Laurel (Katie Cassidy) and Thea (Willa Holland) make good on their promise from episode 2 to travel back to the Lazarus Pit in the hopes of resurrecting Laurel’s long-lost sister, Sara (Caity Lotz). Unfortunately, it looks like Malcolm Merlyn (John Barrowman) and Nyssa (Katrina Law) will be standing in their way when they make their triumphant return in Season 4.

“The growing tension between Oliver and Diggle puts both their lives at risk when they go after Damien Darhk and a HIVE-deployed meta-human,” the official plot synopsis reads. “Meanwhile, Laurel talks Thea into returning to Nanda Parbat to ask her father to put Sara into the Lazarus Pit. However, Laurel is surprised when Nyssa refuses to do it.”

While fans of “Arrow” are likely excited for three characters to return in Season 4 -- Malcolm, Nyssa and Sara -- the real crux of the episode seems to be the introduction of yet another DC Comics villain, Double Down. According to the TV spot for the coming episode, which can be viewed below, the CW will bring the comic book character Jeremy Tell to life on screen. According to The Wrap, Double Down is a villain primarily associated with the Flash. When he kills the winner of a card came in a jealous rage, he finds out that his victim was carrying a cursed deck of cards. They are imprinted on his skin as tattoos that he’s now able to peel off and throw with lethal accuracy.

With Thea and Laurel out of town, Team Arrow is down two field operatives, which means that Diggle will need to put aside his beef with Oliver in order to stop the meta-human madman. However, that’s easier said than done to a man that kidnapped your wife and left your newborn baby alone for several hours.
