A heartbroken Cupid returns to Star City with one goal – to destroy anyone in love. The team learns she’s killing couples on their wedding day so Oliver and Felicity decide to pose as bait.

Diggle and Felicity are shocked by Oliver's decision to ask the Bratva for help in taking down Prometheus.

As Slade continues to uncover clues about his son’s last few years, Oliver makes a big decision. Meanwhile, the Green Arrow leads the team into battle against “The Dragon,” a villain who is stealing valuable tech in Star City.

Oliver, Diggle and Felicity disagree with Dinah, Curtis and Rene on how to handle Black Siren. The two teams face off and a fight ensues.

Oliver turns to an old friend to help battle Diaz; Rene is out of the hospital but has a hard time readjusting to life as Wild Dog; Lance discovers something shocking about Black Siren.

In order to track down Diaz from inside prison, Oliver realizes that will require aligning with an old enemy. Meanwhile, in Star City, Felicity’s attempts to root out Diaz are thwarted by Diggle, whose allegiance to ARGUS now requires him to keep civilians like her on the outs. Realizing that she can no longer rely on her old team or old methods, a clear-eyed Felicity resolves to find a new way to go after Diaz.

Oliver makes a choice that will affect his entire life, as well as the lives of everyone he cares about.

After months of covertly pursuing Dante, Diggle and Lyla finally have a solid lead on the elusive terrorist, so they deploy the ARGUS Ghost Initiative to apprehend him. Meanwhile, Oliver tries to bond with Emiko.

The battle between Oliver and Emiko comes to a boiling point which brings back some familiar faces and leaves others in dire jeopardy.

Oliver's mission takes him to Lian Yu where he tries to ignore the repercussions of the looming Crisis until he receives help from an old friend. Meanwhile, a united Team Arrow faces a recognisable villain.
