Oliver isn’t the only one sporting a new suit when Arrow returns for season 4. I'm not a big fan of this costume. As revealed at Comic-Con, season 4 finds Diggle ( David Ramsey ) actually wearing a super suit, despite never being a fan of them. “We try to be very consistent with our characterization,” EP Marc Guggenheim recently told EW of Diggle’s reaction to the suit. “I don’t think Diggle looks at it as a costume per se,” he continues. “Oliver [Stephen Amell], in the last season, gave him advice in terms of concealing his identity, and so Diggle approaches it from a very practical standpoint. He followed Oliver’s advice and he’s got a means of concealing his identity, but I think Diggle would probably react to anyone calling it a costume.” Arrow is slated to return Wednesday, Oct. 7 at 8 p.m. ET on The CW.
