Star City has had a rough ride in Arrow Season 6 so far thanks to Cayden James and his consortium of bad guys.
Team Arrow was split in two after Dinah, Curtis, and Rene found out that Original Team Arrow was keeping tabs on them.
At first, Original Team Arrow and Team Arrow-less were on cordial terms and shared information, but that stopped being the case after the death of Vigilante.
“Collision Course” saw the two teams come to blows, and the conflict indicates that Star City could be doomed for the foreseeable future.
