After the events of "The Wrath of Savitar," the latest episode of "The Flash," Barry will have to enter the Speed Force to rescue Wally West. The new promo for "Into the Speed Force" shows exactly who Barry will have to face in order to save Kid Flash.
"The Wrath of Savitar" found Wally struggling with visions of Savitar, until ultimately those visions manipulated Wally into falling for Savitar’s plan. As a result, Wally traded places with Savitar and was subsequently trapped in the Speed Force. This fulfilled the prophecy that "one would face a fate even worse than death." However, because he has been inside the Speed Force before, Barry believes that he can enter it and save Wally.
Barry last entered the Speed Force in Season 2's "The Runaway Dinosaur," where he had to face the ghost of his mother. In next week's episode, he will encounter the ghosts of Eddie Thawne, Ronnie Raymond and Leonard "Captain Cold" Snart. The return of each of these actors has been long anticipated, as they all died during previous seasons.
