As established, Darhk is the man at the head of H.I.V.E and a character who has been lurking in the shadows for the past couple of seasons, pulling all sorts of strings and impacting on Oliver, Diggle and Ras. The Demons Head recounts that they progressed through the League together, but only one could be Heir to the Demon. That honour went to Ras, but he hesitated to kill his friend, and as he tells Oliver: He has vexed me ever since. He also lets slip to Oliver that as well as taking his loyalists with him he took water from the Lazarus Pit, and all of this serves to inform us that Darhk is at least very close to being an equal of Ras, and is going to cause Olly some big problems down the line. We almost got a glimpse of him in the S3 finale, but he had fled Starling City before Oliver or Ras could find him, leaving behind his assistant to die, but not before he tells Oliver: "Its amusing thinks he can catch my employer unawares. It all adds up to Darhk being a powerful foe for Team Arrow next season.
