Since its very first season, Arrow has been dropping subtle Green Lantern Easter eggs, as well as teasing the possibility that Oliver Queen could link up with Hal Jordan (or another Green Lantern) at some point during the show’s run.
This seemed to take a step closer towards becoming a reality with the introduction of the Green Lantern supporting character Susan Williams (Carly Pope) in the fifth season; however, it seems that isn’t the case, as Arrow executive producer Wendy Mericle has ruled out the possibility of introducing the Green Lantern Corps during an interview with CBR.
“One of the fun parts of the show is that you can put these characters in and the Easter eggs and the fans that know this universe so well respond to it on varying levels of excitement and whatnot, but the thing about [Susan’s] character that’s so intriguing is that it operates on that level. It also operates because she’s someone who’s very intrigued by Oliver, who’s going to uncover some secrets that Oliver has, which is going to be really fun, and is a fun nod to the Green Lantern, who obviously we could never bring on the show.”
That seems pretty definitive, but seeing as The CW managed to convince Warner Bros. and DC to allow the Man of Steel to appear in Supergirl, who knows what the future holds…
