Fresh off crossing over with "Arrow," fellow DC Comics-based CW series "The Flash" reaches its first midseason finale next week with an episode titled "The Man in the Yellow Suit" -- not only does that title suggest Reverse Flash will be showing up, the official network description for the episode goes ahead and confirms it.

Now, Reverse Flash -- whose TV series identity is a mystery at this point -- isn't actually in these eight photos released by The CW, but Barry Allen/The Flash (Grant Gustin), Caitlin Snow (Danielle Panabaker), Cisco Ramon (Carlos Valdes) and Joe West (Jesse L. Martin) all are.

Directed by Ralph Hemecker and written by Todd Helbing & Aaron Helbing, "The Man in the Yellow Suit" is scheduled to air 8 p.m. Tuesday, Dec. 9 on The CW. Here's the official episode synopsis:

BARRY COMES FACE-TO-FACE WITH THE MAN IN THE YELLOW SUIT/AMANDA PAYS RETURNS TO THE FLASH - 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). Ralph Hemecker directed the episode written by Todd Helbing & Aaron Helbing (#109). Original airdate 12/9/2014.
