In my opinion, one of the best things to come out of Arrow was Oliver Queen’s bodyguard turned best friend, John Diggle. What originally seemed to be nothing but a professional relationship, over Arrow’s 8 year run we got to see Oliver and John’s relationship truly blossom into one that advanced even past friendship and eventually resembled brotherhood. We got to see John’s character evolve from a basic security guard, to a family man and eventually a hero and leader. And while we got to see Oliver Queen’s journey come full circle with Arrow ending, John’s feelings during the finale reflected what I was thinking. He wasn’t ready for his time as a hero to end and I wasn’t ready to say goodbye to such a great character! Thankfully, the end of Arrow teased an exciting future lay ahead for Diggle so I’ve decided to write about this and speculate on what the future may hold for Mr John Diggle.
First thing’s first, I’ll just warn you that I’m about to write about a huge spoiler from Arrow’s final episode so if you haven’t watched it yet and don’t want it to be ruined for you SPOILERS are coming!!!!
Now that’s out of the way let’s get into it! The long teased hint at John Diggle potentially being a modified iteration on the Green Lantern John Stewart FINALLY came into fruition. After learning John’s step father was named Roy Stewart (an obvious easter egg on John Stewart) and Earth 90’s Barry Allen hinting that Earth 90’s John Diggle was a Green Lantern on his Earth, the Arrow finale saw John find a Green Lantern ring and indicated that John’s hero days are only just beginning!
Earlier on in the Arrow finale, John announced himself, Lyla and their children were moving to Metropolis which is an interesting city to choose. In my opinion, this sets up the possibility for John to make sporadic appearances in the upcoming Superman and Lois TV show with that being set in Metropolis. While I don’t expect Diggle to be a main character, I can imagine him taking on a supporting role and appearing only several times a year. This would also keep him in the loop for possible future crossovers when he will be most needed.
I don’t think we’ll get to see Diggle in HBO’s Green Lantern show. I think with it being on an entirely new network, they’re probably going to want to cast their own Green Lanterns and will probably want to include a version of John Stewart that is more faithful to the source material. This doesn’t phase me too much as it makes sense for the HBO show to start afresh similarly to Arrow choosing not to use Justin Hartley’s Green Arrow and casting Stephen Amell instead.
Seeing John’s early adventures as Green Lantern will make for exciting television and I really hope we get to see at least a glimpse of them. What do you guys think? Do you think we’ve seen the last of Diggle in the Arrowverse? Or will we get to see him as a fully fledged Green Lantern? Feel free to leave your thoughts in the comments!
