Complete story — includes the ending

Oliver's team captures an associate of Church's and delivers him and his loot to the Star City Police Department (SCPD). Afterward, Rory formally leaves the team, saying that he cannot work with Felicity. Oliver leaves Star City to help Lyla break Diggle out of prison over Felicity and the team's objections. Quentin and Chase personally deliver the evidence to the SCPD, which turns out to be a disguised bomb. The explosion allows Church's group to break in and steal weapons from evidence. Oliver infiltrates a federal prison and locates Diggle, who agrees to escape to safeguard Oliver. Oliver takes him and Lyla to a H.I.V.E. safe house. Felicity attempts to reconcile matters with Rory. She and the team determine that Church is planning an assault on the SCPD's anti-crime unit, where Chase is interrogating Church's man. Rory rejoins the team and they help everyone inside escape the attack. However, Curtis is injured and Church captures Rene, intending to torture him to death. Oliver returns and vows to rescue Rene, while Chase decides to trust the vigilantes' motives. In flashbacks, Anatoly tasks Oliver with gaining information from, and then killing, an associate of Kovar. Oliver completes the assignment and Anatoly welcomes him into the Bratva.
