As Adrian said he's always 10 steps ahead. Look at what's happened because he manipulated Oliver into killing Billy, so many dominos have fallen because of that one action with Green Arrow being discredited and Felicity joining Helix, which I'm convinced is what Prometheus wanted. True they exposed him but they also made Felicity disable a homeland secruity drone which could have easily allowed them to smuggle a weapon into the country, in exchange for finding Susan which felt way too easy and yet they couldn't find Oliver? I also think E2-Laurel was used to motivate Oliver into finding Dinah because Prometheus is planning on killing her to prove his point. There are many things that have happened or been implied because of something else Prometheus has done so it wouldn't surprise me if almost everything this season has been entirely his doing.

Prometheus/Vigilante, I guess that is a long shot, but I can't figure out who else Vigilante is and also note when Artemis fired an arrow at him he shot the arrow into several dozen pieces and later when Green Arrow fired an arrow at Prometheus he sliced the arrow into several dozen pieces almost exactly the same.

As for Prometheus and Artemis being related I still think I'm right because it would make her motives much more clear and showcase a truly evil version of Oliver by adding an evil version of his sister, and it would explain why Prometheus would seek her out of all people and why he would reveal his identity to her.
