Do not attempt to adjust your screen, what you're seeing is in fact a clip from a new episode of "The Flash" and not a rerun from Season 1. "The Flash" is going back in time again in the March 29 episode -- "Flash Back" -- and based on the above Zap2it-exclusive clip, that means the return of some familiar faces.

First and foremost, Eddie Thawne (Rick Cosnett) is back from the dead, as Barry (Grant Gustin) is racing back to get help in defeating Zoom (Teddy Sears). As if seeing Eddie alive and well isn't enough, going back to those days also means the return of Eobard Thawne in the body of Harrison Wells (Tom Cavanagh), wheelchair and all.

Seeing this quick glimpse at Earth-1's Wells not shows just how different -- calm, gentle in a way -- he is compared to Earth-2's Harry. He also gets to slip in his signature, "Run, Barry. Run."

Of course, it's Barry running into danger as something that looks like a straight up ghost that's terrorizing Eddie and the Central City Police Department.

Though Barry went back in time looking for help, he's not going home without saving the day yet again.
