Guess where “Arrow” actor Aaron Ramsey was last afternoon? At the writer’s room for “The Flash”!

A photo posted by Aaron, who plays John Diggle, on his Instagram page has raised several questions. He captioned the photo with a teasing possibility of another Arrow/ Flash crossover. He said:

“Made a visit to #theflash writers room.. Can only mean one thing.. #arrow&theflash”

Fans of both the TV shows know that characters from each show appear regularly in each other’s episodes and it’s no secret that a crossover was on the cards.

Executive producer Andrew Kreisberg was quoted by Movie Web in saying:

“The Diggles arrive in Central City to help Barry take on King Shark who has escaped from ARGUS and is hellbent on completing his mission of destroying The Flash.”

King Shark got his first ever live-action appearance in the episode “Fury of Firestorm” in “Flash’s” Season 2. The iconic DC character has his evil plans and Diggle is going to help Flash out to defeat him. While the appearance of King Shark was glorified to a humongous extent last year, it seems like he is going to get more screen time in another crossover. This begs the question: Is it the end for Diggle and Lyla as they come to rescue the Flash?

“Arrow” and “Flash” have already made a crossover which aired last month. “Legends of Yesterday” and “Legends of Today” were some of the episodes aired. According to Comic, both episodes served as an introductory movie for Hawkgirl and Hawkman.

“The Flash” and “Arrow” are easily one of the top rated shows for ‘The CW’ and it has been one of most highly rated shows on the network. A second collaboration only makes sense for the producers and fans.

“The Flash” returns to ‘The CW’ on January 19, while “The Arrow” starts from January 20.
