'The Flash' Comes Face-to-Face with Reverse Flash on Tonight's Mid-Season Finale

Barry (Grant Gustin) looks a little beat up in this still from tonight’s mid-season finale of The Flash.

In “The Man in the Yellow Suit,” Barry 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 Flash mid-season finale airs TONIGHT, December 9 @ 8PM on The CW!
