In this episode of Arrow, it is finally revealed who Prometheus is. Adrian Chase is Prometheus, which I did not expect. I thought that Adrian Chase would be The Vigilante because in the comics Adrian Chase is The Vigilante. Another surprise is that Oliver publicly announces to hunt the Green Arrow. Will Oliver be able to fight crime as the Green Arrow anymore? Last time Green Arrow was hunted, Oliver couldn't do anything without running into the police. Felicity decides to go dark side in this episode. Felicity joins the hacking group which gave her Pandora. Felicity seems to be returning to her past ways and is hacking others for bad reasons. The one question remaining is who is The Vigilante? Overall another good episode of Arrow and I look forward to the next episode.
