CW’s Arrow superhero program will lose another one of its longstanding actors, Variety reports. Paul Blackthorne, known to fans as Quentin Lance, is leaving the show prior to its forthcoming seventh season.

PAUL BLACKTHORNE IS LEAVING ARROW

Blackthorne has been a cast member of the show since its 2012 pilot episode, with his character evolving from a Starling City police detective to the deputy mayor. In addition to his starring role on Arrow, Blackthorne portrayed his DC character in its spin-offs, The Flash and Legends of Tomorrow.

Only two other major faces from the pilot, Stephen Amell (Oliver Queen/The Arrow) and David Ramsey (Diggle/Spartan), remain on staff. Consequently, Blackthorne will now dethrone Willa Holland, who portrayed the Thea Queen, as the longest-running cast member to depart from Arrow. However, Colton Haynes will return to the program for its upcoming season, reprising his role as Oliver’s sidekick Roy Harper, who’s better known to supervillains as Arsenal.
