At the end of season four of the CW’s Arrow, the team that had surrounded Oliver Queen for so many years parted ways. His sister Thea said goodbye to the vigilante life to pursue a normal one and deal with her “bloodlust” which was caused by being resurrected in the Lazarus Pit. John Diggle left the city to be able to move on from having to kill his own brother.
The only one who stayed beside Oliver is Felicity Smoak. As Oliver does not intend to stop protecting Star City at night, he will need to recruit new Team Arrow members; which is what he does in a newly released teaser trailer for season five.
Arrow returns on the CW October 4.
