Arrow: Season 1, Episode 11

1 - 11: Trust But Verify

Arrow's next in line on his list is the commanding officer of Diggle (David Ramsey) and mentor from Afghanistan, Ted Gaynor (guest star Ben Browder). He suspects that Ted is responsible for recent armoured 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, which puts him at odds with Diggle. On the other hand, Thea suspects that Moira is having an affair with Malcolm (guest star John Barrowman). Tommy (Colin Donnell) and Laurel (Katie Cassidy) have an awkward dinner with Malcolm.
