Arrow's final season will soon premiere with a stretch of episodes meant to build up to the highly-anticipated "Crisis on Infinite Earths." That crossover event will bring characters from the CW's various superhero shows together alongside more than a few fan-favorite guest stars. Now, a new behind-the-scenes photo from the set reveals that part of Team Arrow will run into an old friend during (or perhaps even before) the crossover.
On Instagram, Arrow star David Ramsey shared a picture of himself with co-stars Stephen Amell, Katherine McNamara and Matt Ryan, indicating that Oliver Queen and John Diggle will once again cross paths with the Master of the Dark Arts himself, John Constantine. What's more, the photo seemingly confirms Oliver Queen will eventually meet his future daughter, Mia Smoak.
Ryan's Constantine appeared in Arrow Season 4 episode "Haunted," where he helped rescue Sara Lance's soul. He's now a regular alongside Sara on DC's Legends of Tomorrow.
"Crisis on Infinite Earths" begins Sunday, Dec. 8 at 8 p.m. ET/PT on Supergirl, then continues in Batwoman on Monday, Dec. 9 at 8 p.m. ET/PT and in The Flash on Tuesday, Dec. 10 at 8 p.m. ET/PT. After the winter hiatus, the crossover will conclude on Tuesday, Jan. 14 in Arrow at 8 p.m. ET/PT and in DC's Legends of Tomorrow at 9 p.m. ET/PT.
