Season 3 Episodes
01: The Calm
With crime in Starling City at an all-time low thanks to the Arrow and his team, Oliver thinks he can finally balance being both the Arrow and Oliver Queen and asks Felicity out on a date. However, when a new villain (guest star Peter Stormare) emerges, who has claimed the name Vertigo from the recently deceased Count, Oliver is caught off-guard and someone close to him is hurt. Oliver and a newly suited up Roy take on the Count. Meanwhile, Diggle becomes a father, Lance is promoted to Captain, Laurel joins Arrow’s inner circle and Felicity gets a part-time job at a tech store to make ends meet. Also, Oliver fights to regain his company, Queen Consolidated, but comes up against a very worthy opponent—the charming Ray Palmer.
Lance calls the Arrow when another archer appears in town and starts skewering businessmen. Diggle uses A.R.G.U.S. to find the archer’s identity; he is a man named Simon Lacroix (guest star Matt Ward) who goes by the codename Komodo. However, the team hits a rough patch with the mission and gets help from a surprising source—Laurel. Meanwhile, Oliver begins to worry that he hasn’t heard from Thea, which forces Roy to tell him the truth about why she left town. Ray Palmer pursues Felicity. In the flashback, Maseo (guest star Karl Yune) tells Oliver that Amanda Waller has ordered his first kill. As Oliver looks down the scope of the rifle, he sees the target is his best friend Tommy (guest star Colin Donnell). Despite her promise to her sister, Laurel debates sharing a secret about Sara with Lance.

Oliver decides it’s time for Thea to come back to Starling City, so he packs for Corto Maltese, where Felicity has traced Thea’s whereabouts.

Feeling responsible for Thea’s departure, Roy joins Oliver and Diggle on their journey. Shaw double-crosses Diggle, putting numerous A.R.G.U.S. agents, including Lyla, at risk. Meanwhile, Laurel meets Ted Grant, and Felicity adjusts to her new job.

The Arrow joins the fight and gets help from an old friend—The Flash (guest star Grant Gustin).
