The next person on Arrow's list is Diggle's commanding officer and mentor from Afghanistan, Ted Gaynor (guest star BEN BROWDER). Oliver suspects Ted is responsible for recent armored truck robberies, but Diggle defends Ted and takes a job at Ted's security company to keep an eye on him. Oliver decides to make a move on Ted, putting him at odds with Diggle. Meanwhile, Thea suspects that Moira is having an affair with Malcolm (guest star JOHN BARROWMAN); and Tommy and Laurel have an awkward dinner with him.

Chloe returns and begs Clark to kill Davis, claiming he can no longer keep the beast under control. Tess has assembled a team of meteor freaks, including Plastique, to track down Davis so Clark can kill him. However, things get out of hand once Tess’ team discovers she is double-crossing them.

In the season four premiere, Oliver and Felicity must return home to help the team against attacks by "ghost" assassins led by Damien Darhk (Neal McDonough).
