On Wednesday's episode of Arrow, Prometheus revealed to Oliver that his father, Robert Queen, was actually a murderer. While that was meant to bring Oliver down, it actually inspired him to move on from his father's crusade and forge ahead with his own mission. He then turned the tables on Prometheus when he told Chase that his father, Justin Claybourne, had meant to disown him before his death. It was a battle of Whose Father Was Worse, and Prometheus lost.
With Prometheus beaten and imprisoned at A.R.G.U.S., it appeared that Team Arrow was at last triumphant. Unfortunately, however, that's not the case. In the trailer for next week's episode "Missing," Prometheus sets his final plan into motion. Kidnapping Dinah and Curtis (and possibly Oliver's son William), Prometheus will use two key allies to set Team Arrow up for a massive failure. Will Prometheus' friends use Dinah and Curtis as leverage to free their sadistic leader, or does Prometheus actually want them dead?
