Complete story — includes the ending
Dinah and Sergeant Bingsley interrogate Team Arrow, who are in SCPD custody accused of killing two subway station security guards. They reveal they recruited Roy Harper to help with an operation where they successfully prevented the Ninth Circle from releasing their biological weapon. After Oliver names Emiko as the killer, the team is released since their stories line up. It is revealed that they all lied and that Dinah was part of the operation, in which Roy killed the guards in a fit of rage. The team decides to protect Roy in order to save the team and be able to continue hunting the Ninth Circle. Oliver recognizes the bloodlust he witnessed and meets a remorseful Roy, who reveals that he died battling the Thanatos Guild and was then revived by Thea Queen and Nyssa al Ghul via a Lazarus Pit. Felicity locates the Ninth Circle's headquarters, where Oliver confronts Emiko, who reveals she has sent the subway station security footage to Bingsley. Emiko comes clean about her role in Robert Queen's death and states that her goal is to destroy Oliver's legacy while he dies a villain like their father. Emiko blows up the building, burying Oliver.
