Yet another one of Arrow's original cast is set to depart the show this season.

Paul Blackthorne, who's played Quentin Lance since the CW drama debut in 2012, won't return in the fall for Season 7. His exit follows that of fellow original cast member Willa Holland, who played Thea Queen.

With this departure, only Stephen Amell (Oliver Queen/The Arrow) and David Ramsey (Diggle/Spartan) remain of the original series regulars from the pilot. To compensate for the loss of several cast members, Colton Haynes will return in Season 7 as Arsenal.

Those are only a couple of the changes that have occurred on Arrow this season. Warner Bros. Television fired executive producer Andrew Kreisberg in November amid multiple allegations of sexual harassment, and last month co-showrunners Marc Guggenheim and Wendy Mericle announced they're stepping down from their roles;  Beth Schwartz was promoted to showrunner in their place. Guggenheim will shift to a role as executive consultant on both Arrow and DC's Legends of Tomorrow.
