Things move fast in the world of "The Flash," which may explain why The CW has released nine new images from the second episode of the show's second season four days before the season premiere is scheduled to air. Taking its name from the famous "Flash of Two Worlds" comics story by Gardner Fox and Carmine Infantino, the episode looks to feature a lot of Teddy Sears as Jay Garrick, the original Flash in DC Comics history, appropriately echoing that 1961 tale. Plus, there's a look at Kett Turton as Eddie Slick, a character better known as Firestorm villain Sand Demon.

"The Flash of Two Worlds," the second episode of the second season of "The Flash," airs 8 p.m. Tuesday, Oct. 13 on The CW. Here's the official description of the episode:

INTRODUCING JAY GARRICK - Jay Garrick (guest star Teddy Sears), a mysterious man from Earth-2, appears at S.T.A.R. Labs with a dire warning about an evil speedster named Zoom, who is set on destroying The Flash. Barry (Grant Gustin) and the team must decide if they can trust this stranger even as they face yet another powerful meta-human. Meanwhile, Joe (Jesse L. Martin) must deal with a determined officer named Patty Spivot (guest star Shantal VanSanten) who wants to join his meta-human task force. Jesse Warn directed the episode written by Aaron Helbing & Todd Helbing (#202).
