John Diggle has been keeping himself busy this season on Arrow. Between working with the team on finding Sara’s killer and keeping the streets of Starling City safe, as well as caring for his new daughter, he has a packed schedule. However, there’s one lingering plot-thread concerning Diggle that still has yet to be more deeply touched upon: his brother Andy’s murder. Andy’s death has been a chip on Diggle’s shoulder since the series began, and is one of the long-running mysteries of the show, but according to actor David Ramsey, it will be touched upon soon.
Ramsey hinted to ET Online that the series would be following up on the people behind Andy’s death soon and also teased the return of a certain A.R.G.U.S. team. Said Ramsey:
"There are some unanswered things about Diggle that will start to be uncovered. Those rocks are going to get turned over [and] you'll see Suicide Squad happen again -- to some degree -- and the Diggle-HIVE conflict.”
It was established in Season 1 that Floyd Lawton, a.k.a. Deadshot, killed Diggle’s brother. However, in the Season 2 episode “Keep Your Enemies Closer,” Deadshot told Diggle that he was hired to take Andy out by an organization called H.I.V.E., although the mysterious group has barely been mentioned since then. The Suicide Squad was introduced in the Season 2 episode of the same name, and the team currently stars in the Arrow Season 2.5 digital-first comic book’s back-up story. If the Squad is returning, this likely means the audience will also be reunited with Deadshot, who is the main member of A.R.G.U.S.’s team of incarcerated super villains and was last seen in the Season 2 finale “Unthinkable” (hesitantly) helping Diggle and Lyla delay Amanda Waller’s drone strike on Starling City.
In the comics, H.I.V.E. (Hierarchy of International Vengeance and Extermination) is a team of super villains that has clashed with heroes like Superman and the Teen Titans. Slade Wilson was the main antagonist of Season 2, and Ra’s al Ghul is the big baddie for Season 3, so Team Arrow hasn’t had a lot of time to investigate the organization, much less run into them. I suspect that much like the frequent mentions of Ra’s last year, H.I.V.E. will be touched upon at several points this season, setting them up as either the main antagonists for Season 4 or at least big players for future Arrow story-lines. Diggle may start out going against the organization alone, but it’s likely that his teammates will be drawn into the conflict. If H.I.V.E. is being influenced by its comic book roots, this might also mean we’ll see several Arrow villains being recruited by this shadowy group.
