FlashTVNews is reporting that CW has released the description and airdate for the December 4 episode of Arrow that brings Barry Allen back to TV.
Arrow #2.8 “The Scientist” Description – Grant Gustin Guest Stars As Barry Allen (The Flash)
BARRY ALLEN COMES TO STARLING CITY — A seemingly impossible robbery at Queen Consolidated’s Applied Sciences Division brings Central City police scientist Barry Allen (guest star Grant Gustin) to town. Citing a similar case back home, Barry offers to help Oliver (Stephen Amell) and team with the investigation. Oliver senses there is more to Barry than meets the eye, but he’s distracted by the similarities between this current case and something that happened on the island. Meanwhile, Felicity (Emily Bett Rickards) takes a liking to Barry, which doesn’t go unnoticed by Oliver. Sin (guest star Bex Taylor-Klaus) asks Roy (Colton Haynes) for help when a friend of hers goes missing. Roy is surprised when Thea (Willa Holland) not only encourages him to help, but joins the search. Unfortunately, Sin’s friend is connected to Brother Blood (guest star Kevin Alejandro), and their search ultimately gets one of them seriously injured. Michael Schultz directed the episode with story by Greg Berlanti & Andrew Kresiberg and teleplay by Andrew Kreisberg & Geoff Johns (#208).


On July 30th, the news broke that a live action Flash series would soon be joining the successful “Arrow” show currently being broadcast on the CW network. The character of Barry Allen, now appearing in comics as the “New 52” version of the famous speedster, will be introduced on Arrow before spinning off into his own adventures. As most comic fans know, Barry Allen is not the only person to wear the crimson and yellow, and the question of whether or not he is the most popular (or most “iconic” as DC has branded him) is still a matter of heated debate. His comic book sidekick-turned-successor Wally West is both a fan favorite character and the Flash many people best remember, due to his appearances in the animated Justice League, Teen Titans, and Young Justice cartoons. Of course Barry will be the star of the new Flash series, and he is certainly the face of the franchise that Dan Didio and Geoff Johns want the world to see.
