'Arrow' Series Finale Seemingly Confirms This Long-Running Fan Theory!

Spoilers ahead! Don’t read if you haven’t watched the series finale of Arrow.

Fans totally went crazy over the final moments of the Arrow series finale!

The finale saw the end of Oliver Queen (Stephen Amell) sacrificing himself in order to reboot the universe and create the combined Earth Prime universe that all the Arrowverse heroes now live in.

At the end of the episode, the Green Arrow’s bodyguard John Diggle (David Ramsey) teases new adventures to come, and we see a meteor streak across the sky. Diggle then goes to the crash site and finds a box with an emerald ring inside – aka the power ring worn by The Green Lantern.

For years, it has been a long-running theory by Arrow fans that Diggle would turn out to be Green Lantern John Stewart. The show’s been dropping Easter eggs on that theory for years with us learning that Diggle’s grandfather’s last name was “Stewart” and once in an alternate universe version of the Flash once asked Diggle “where’s your ring?” when he met him.

“That was something that we’ve been working our way towards for a good long time now,” showrunner Marc Guggenheim shared with Deadline. “I think for maybe about a year, year-and-a-half we’ve known that this was a moment we’re going to be able to do, and it made sense to do it in the finale because my attitude is that even though the show ends, as long as the characters are alive the characters continue on. One of the things we wanted to do with the finale was give you a sense as to what their post-show trajectories would be. And certainly, Diggle’s is probably the most intriguing.”

Here’s to hoping we get more from The Green Lantern in the future!
