As we return to Star City for the midseason premiere, we find Team Arrow - as the title would suggest - divided. While OTA (Oliver, Diggle, and Felicity) continue the fight to protect the city against the team of villains Cayden James has brought together, the remaining trio (Curtis, Dinah, and Rene) have left. As Oliver partners with a familiar name to bring down Cayden, he remains confident that the remaining team can still complete the mission, but unexpected threats intervene.
