"Arrow" fans haven't seen the last of Digger Harkness.

The classic DC Comics rogue, better known as Captain Boomerang, was introduced on the third season of "Arrow," in the two-part crossover with "The Flash," but hasn't been shown since. However, actor Nick Tarabay suggests that could change soon.

"Who really misses this guy?" the actor wrote in a tweet containing a photo of Boomerang. "Cause as you know....What goes around ALWAYS comes back around."

When Boomerang was last seen, he was incarcerated in the secret A.R.G.U.S. supermax prison on Lian Yu. How or when Boomerang might escape will have to remain mystery as of now.

Although the villain was primarily featured in "Arrow," it's possible his appearance will be in one of the other Arrowverse shows. However, this season has already brought back previous villains, such as China White, Cupid and Lady Cop in the episode "The Sin-Eater."
