The CW's Arrow may have wrapped earlier this year, but in true DC multiverse fashion, some of the familiar faces you got to know and love across the show's eight seasons aren't ready to call it quits just yet. Actor David Ramsey, who played Oliver Queen's friend and fellow superhero John Diggle, will be returning to the shared TV universe both in front of and behind the camera according to Deadline.

　　Ramsey will be reprising his role as Diggle AKA Spartan in the upcoming Superman & Lois--and he’ll be joined by some familiar faces:Supergirl, The Flash, and Batwoman. Interestingly, however, he will also be playing a new role in Legends of Tomorrow, but who that role is or what it might entail is being kept under wraps.

　　The nature of a show like Legends of Tomorrow, where time travel and dimensional hop-scotch are commonplace, means that this mystery role could be anything from an alternate reality version of Diggle to an entirely new character from DC's rich pantheon of characters. It's also worth remembering that in Arrow's series finale, Diggle was shown moving to Metropolis and finding a green ring, which fans have assumed is a reference to the rings worn by the Green Lantern Corps.

　　In DC Comics, Lantern Corps rings select their owners by emotional resonance, with green tuning into extremely strong willpower. The Green Lantern Corps functions as something of a police force for the galaxy. They've divided up all of space into sectors, and typically patrol in pairs. Earth, residing in Sector 2814, is something of an anomaly in the sector system however, with six human Green Lanterns--eight, if you count both Alan Scott, the Golden Age Green Lantern who technically doesn't draw his power from the Corps, and Jo Mullein, a Green Lantern to be added in DC's upcoming Future State event.

　　So what does all this mean for Diggle? Well, it's complicated--and very open ended. The only way we'll know for sure what his future holds will be to tune in as the Arrowverse continues to grow and change. Interestingly, DC has already greenlit a Green Lantern show for HBO Max, the platform that is home to non-Arrowverse DC shows like Titans and Doom Patrol. Thus far, there has been no real crossover between the Arrowverse and non-Arrowverse shows, but stranger things have happened in the multiverse.

　　Also, in addition to acting, Ramsey will be directing five total episodes across the Arrowverse, including Superman & Lois and Supergirl.
