Complete story — includes the ending
The newly promoted Captain Quentin Lance calls off the task-force hunting the Arrow. Elsewhere, Werner Zytle, who has claimed the mantle of Vertigo, attempts to kill the Arrow in a bid to raise his profile. After losing the first battle, Oliver Queen and Roy Harper are able to stop Zytle with some help from Sara Lance, who is back in town for unknown reasons. Meanwhile, businessman Ray Palmer successfully acquires Queen Consolidated, intending to rebuild the city and rename it "Star City". John Diggle and Lyla Michaels welcome a baby girl, which convinces Diggle to take Oliver's suggestion and retire from field duty. Oliver and Felicity Smoak go on a first date, but Oliver ends it, explaining how he cannot be both the Arrow and Oliver, although he acknowledges loving her. Sara is shot in the chest with arrows by an unseen figure before falling from a rooftop to her death. In flashbacks, Amanda Waller assigns agent Maseo Yamashiro as Oliver's handler. After numerous failed attempts to escape, Oliver agrees to proceed with his training to prevent Waller from murdering Maseo's family as punishment for his failure to restrain Oliver.
