When we spoke with him yesterday, Ramsey remained mum on the future, except for one tease that we withheld until after tonight's episode had played out:
"I can say this: We aren't done with the investigation of H.I.V.E.," Ramsey told ComicBook.com. "We've planted that nugget, we're going to explore that. Andy Diggle's connection to H.I.V.E., we're not done exploring that. So Diggle, Deadshot, H.I.V.E., Andy Diggle is not over."
The death of Diggle's brother -- killed by Suicide Squad member Floyd "Deadshot" Lawton on behalf of H.I.V.E. -- has been a central, motivating event for the character since the series began. While nothing much is known about H.I.V.E. just yet on Arrow, in the comics they've got relationships with both Slade Wilson and Brother Blood, who are driving much of the series's main plot this year.
Given the development that Deadshot/Lawton got in this episode, it wouldn't be surprising to see Michael Rowe return to reprise that role and play a part in whatever comes next between Arrow and H.I.V.E.
