Complete story — includes the ending
With Chase having broken him, Oliver disbands the team and calls in the Bratva to take out Chase. Diggle tries to talk Oliver out of it, reminding him that there are better ways of doing things. Felicity goes to Helix and manages to find pixelated footage of Chase taking off his Prometheus mask. Oliver allows the Bratva to steal diabetes medicine as a down-payment, but they are stopped by the team. Diggle tells Oliver that they can fix him if he is willing to accept help. Oliver rejoins the team, taking out the Bratva and saving hostages that Anatoly had taken as leverage. Felicity and Curtis manage to decode Chase's pixelation device, revealing Prometheus' identity to the police. Oliver claims he's not ready to put the hood back on yet but, with his team, it will be sooner rather than later. When Chase's guards try to arrest him, he kills them and leaves his safe house. In flashbacks, Oliver wants to return to Lian Yu, so Anatoly plans one last heist to help sick children, hoping to convince Oliver to stay, but Oliver still intends to return to Lian Yu in order to stage his dramatic return to Starling City.
