There has been a lot of speculation and controversy over the identity of the Reverse Flash, but in the mid-season finale "The Man in the Yellow Suit" he was seemingly unmasked. However star Grant Gustin (Berry Allen/The Flash) says there yet another twist in the story.
“There’s a big twist that even surprised me,” Gustin tells EW. “I’ve seen all the predictions online. No one has predicted the big twist that’s coming at the end of this season.”
The Flash mid-season premiere titled "Revenge of the Rogues" premieres January 20th at 8pm on the CW.
