After the "Flash vs. Arrow" episode of The Flash, The CW released a sneak preview for next week's episode, which is called "The Man in the Yellow Suit."
In "The Man in the Yellow Suit" episode, Barry (Grant Gustin) finds himself face-to-face with his nemesis, the man in the yellow suit, a.k.a. Reverse Flash, who killed his mother. Barry is frustrated when the Reverse Flash escapes, but Dr. Wells (Tom Cavanagh) and Cisco (Carlos Valdes) come up with a plan to trap him. All they need is bait, so they turn to Dr. Tina McGee (guest star Amanda Pays) from Mercury Labs to help. Meanwhile, it's Christmas at The West household and Iris (Candice Patton) is in full holiday cheer. Eddie (Rick Cosnett) gives her a surprising gift but also leaves her with a question that could change her life. Joe (Jesse L. Martin) joins the search for the man in yellow and ends up in the crossfire. Caitlin (Danielle Panabaker) finds Ronnie (Robbie Amell).
"The Man in the Yellow Suit" episode is directed by Ralph Hemecker and written by Todd Helbing & Aaron Helbing. The "The Man in the Yellow Suit" episode of The Flash airs on December 9, 2014 at 8 PM ET on The CW.
