"The Man in the Yellow Suit" is the ninth episode of the first season of The Flash and the ninth episode overall. It aired on December 9, 2014.
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 and Cisco come up with a plan to trap him. All they need is bait, so they turn to Dr. Tina McGee from Mercury Labs to help. Meanwhile, it’s Christmas at the West household and Iris is in full holiday cheer. Eddie gives her a surprising gift but also leaves her with a question that could change her life. Joe joins the search for the man in yellow and ends up in the crossfire. Caitlin finds Ronnie.
- Cisco's shirt depicts the game rock-paper-scissors-lizard-Spock, a game invented by Sam Kass, and many times played by The Big Bang Theory's character, Sheldon Cooper. This is likely a reference to the show, because Sheldon is a huge fan of The Flash.
- When he's being interrogated the man in yellow says, "I'm not like the Flash at all. Some would say I'm the reverse." This a reference to his comic book name, the Reverse-Flash.
- Cisco mentions to Joe the possibility of two speedsters the night Nora Allen was murdered. This could be a possible reference to the existence of other Flashes in the DC multiverse.
