The CW have released the first official description for The Flash 's fourth episode, "The Fastest Man Alive". As well as confirming the small screen debut of Firestorm villain Multiplex, we also get details on Simon Stagg (William Sadler) and Barry Allen's loss of his powers. Check it out!

BARRY HAS FUN WITH HIS NEW POWERS BUT A SETBACK MAKES HIM QUESTION HIS ABILITY TO BE A HERO — Barry (Grant Gustin) escorts Iris (Candice Patton) to a university gathering honoring scientist Simon Stagg (guest star William Sadler). When six gunmen storm the event, Barry changes into The Flash and tries to stop them. While he does save a man’s life, he passes out before he can capture the robbers, which frustrates him. As Dr. Wells (Tom Cavanagh), Caitlin (Danielle Panabaker) and Cisco (Carlos Valdes) scramble to find out what’s wrong with Barry, Joe (Jesse Martin) comes down hard on Barry for taking the law into his own hands and risking his life. Barry realizes that it wasn’t six gunmen but a metahuman named Danton Black (guest star Michael Christopher Smith), who can make multiples of himself. Meanwhile, Iris becomes even more intrigued by the “red streak.” David Nutter directed the episode with story by Greg Berlanti & Andrew Kreisberg and teleplay by Andrew Kreisberg & Geoff Johns.

Some very interesting details in there, though I can't say I'm thrilled about The Flash being known as the "red streak" by the public rather than as a superhero. Hopefully it's not permanent as it brings back some bad memories of a certain "red/blue blur" in Smallville and seems pointless here with Barry Allen wearing a mask and costume! What do you guys think of this and the rest of the plot details revealed above? Be sure to sound off with your thoughts in the usual place.
