Well, this should make Barry Allen’s life harder.

Doug Jones, who will play the villainous Deathbolt on “Arrow,” revealed on Twitter on Saturday that the character will also make an appearance in “The Flash,” marking yet another crossover for the CW superhero dramas.

According to the tweet, Jones will appear in the penultimate episode of “The Flash” season one, called “Rogue Air.” The reveal of the episode title should also give fans a clue on what the episode will cover, and it doesn’t look good for Allen.

The Rogues are a group of Flash villains, and a few classic members of the group have already appeared. Rogues Captain Cold, played by Wentworth Miller, and Heat Wave, played by Dominic Purcell, have previously appeared in the show.

Jones will make his first appearance as Deathbolt on the “Arrow” episode “Broken Arrow” on April 15. “The Flash’s” “Rogue Air” will debut on April 21.
