Yes, actor Rick Cosnett will return to CW’s “The Flash” as Eddie Thawne. However, Eddie Thawne died in the Season 1 finale called “Fast Enough” by shooting himself in the chest to erase his descendant, Eobard Thawne aka the Reverse Flash from history to prevent the destruction of Central City. Well, where there’s a will, there’s a way. “The Flash” writers have found a way to bring him back from the dead. Well, sort of.

TV Line reports that Barry Allen (Grant Gustin) will travel back to a time when Eddie was alive and well. Here is the official synopsis provided by TV Line.

“After the shocking revelation that Zoom is Jay Garrick, Barry is more determined than ever to get back to Earth-2 to stop Zoom forever. Desperate to find a way to increase his speed, Barry decides to travel back in time and masquerade as his earlier self in order to get his arch-nemesis, Dr. Harrison Wells/Eobard Thawne, to teach him how to run faster. However, things don’t go as planned and Barry is stunned to face familiar foe Hartley Rathaway (guest star Andy Mientus), as well as old friend Eddie Thawne (guest star Rick Cosnett). Iris makes peace with her past in order to embrace her future.”

One of the great and sometimes confusing aspects of “The Flash” is the multiverse and time travel element. The presence of these elements in the storyline means that any character from any timeline or any universe can be brought back to the show, whether alive or dead. We have seen multiple versions of characters appear in the show across various timelines and universes. It’s going to be nothing new that another dead character will reappear in the series.

Screenrant had earlier quoted actor Grant Gustin mentioning that Eddie Thawne, despite his obvious death, could very well be brought back if the need arose. “They said when Rick Cosnett was leaving the show, just for personal reasons, there’ll be ways to bring him back. Obviously, it’s true. There’s time travel in the show. But yeah, we have a multiverse on the show that anyone who has died can still be on the show,” Gustin had said.

As for the return of Hartley Rathaway (Andy Mientus), also known as the Pied Piper, his presence could hamper the plans of Flash. We know that he tried to have the particle accelerator at S.T.A.R. labs shut down as he predicted it would explode. Harrison Wells (Tom Cavanagh) did not heed his warning and the explosion gave Rathaway his superhuman hearing. The Pied Piper, as he called himself, then used a special device to control his hearing and created special gloves that emit sonic waves.

Cinemablend notes that Barry’s attempts to get to Earth 2-won’t air until after the Flash and Supergirl crossover event.

“The Flash” returns on March 22 with episode 16, titled “Trajectory.” Meanwhile, The Flash (Ezra Miller) will also appear in a cameo role in Zack Snyder’s “Batman V Superman: Dawn of Justice.”
