Even before the debut of The Flash, diehard fans had a pretty good idea about the show’s future uber villain. During Barry Allen’s (Grant Gustin) initial introduction on Arrow last season, the forensic scientist shared the tale of witnessing his mother being murdered by a blurry figure, a clear nod to DC Comics villain Professor Zoom, otherwise known as the Reverse Flash.
What’s more, when the spin-off began filling out its cast, Rick Cosnett was tapped to play Eddie Thawne, seemingly a play on the name Eobard Thawne, the alter-ego of Professor Zoom. If the producers hadn’t quite hit the nail on the head, the upcoming Dec. 9 episode is titled “The Man in the Yellow Suit.” In other words, we’ll finally see the Reverse Flash in the flesh, not just as a blur from Barry’s memory or a flash of yellow light threatening Joe (Jesse L. Martin) to drop the case or suffer the consequences.
“We’re building towards a confrontation between Barry and the Reverse Flash,” executive producer Andrew Kreisberg tells EW.
