When Oliver returns, however, Diggle makes it very clear that he doesn’t want Oliver on the team.

When an old family friend, Jessica Danforth (guest star JERI RYAN), tells Oliver and Thea that she is going to run for mayor, both Queens are concerned – considering the last three mayors have been murdered.

After Vandal attacks Kendra and Cisco, they turn to Barry for help. Realizing how dangerous Vandal is, Barry takes Kendra to Star City and asks Oliver and the team to hide her until he can figure out how to stop Vandal. However, things quickly go from bad to worse when a man with wings AKA Hawkman (guest star FALK HENTSCHEL) shows up and flies off with Kendra. Meanwhile, Harrison develops a serum to make Barry run faster and asks Jay to test it out.

Meanwhile, Felicity, Thea, Diggle and Laurel work with Team Flash to come up with a weapon powerful enough to destroy Vandal Savage.

The team faces off against a formidable villain nicknamed The Calculator (guest star TOM AMANDES). Meanwhile, Nyssa (recurring guest star KATRINA LAW) makes her move and Roy Harper (former series star COLTON HAYNES) returns to Star City.

Oliver receives an offer from Nyssa that is hard to refuse. Meanwhile, Thea continues to battle her blood lust, and Malcolm steps in to help his daughter. Laurel has a heart-to-heart talk with Nyssa.

Oliver and the team uncover HIVE’s plan to take out Team Arrow once and for all. With HIVE’s next attack imminent, Lance wonders if Donna is safer without him in her life. Meanwhile, with the wedding fast approaching, Oliver begins to feel guilty that he hasn’t told Felicity about his son.

Realizing he needs help battling Darhk, Oliver calls in an old friend – Vixen (guest star MEGALYN E.K.). Using her magical ability to summon animal powers, Vixen gets a lock on Darhk’s location and the team goes to war. Meanwhile, Thea has a heart-to-heart talk with Malcolm.

Brie Larvan aka the Bug-Eyed Bandit (returning guest star EMILY KINNEY) breaks out of jail and turns up at Palmer Tech threatening to kill everyone unless she gets the biochip that is implanted in Felicity’s spine.

Oliver and Diggle learn that Merlyn is going to break Darhk out of prison. Meanwhile, Laurel gets a surprising offer and Felicity has a heart-to-heart talk with Curtis.

Oliver and the team struggle to come to terms with Laurel’s death, especially Diggle who is overwhelmed with guilt for choosing to believe Andy had changed. Meanwhile, Lance refuses to believe his daughter is really gone and asks Nyssa al Ghul to help bring her back. A recent Black Canary sighting in Star City only seems to prove his theory that Laurel isn’t actually dead.

As Oliver and Felicity look for a magical solution to defeat Darhk, a vengeance-driven Diggle gets a lead on Andy’s whereabouts and heads off to confront his brother. Meanwhile, Alex (guest star Parker Young) takes Thea on a vacation that quickly turns into a nightmare.
