The CW Television Network has released a new clip from tonight's "Rogue Time" episode of The Flash.

Last week's episode of The Flash was amazing, but in the final minutes everything that happened was undone when Barry Allen (Grant Gustin) traveled back in time. Will Barry retrace his steps so that he doesn't mess with the previous events or will he use his second chance to alter the future?

Barry seeks help from Dr. Wells, aka Eobard Thawne (Tom Cavanagh), but he is terrified to know about the future. "Time is an extremely fragile construct," Dr. Wells warns. "Any deviation, however small, can result in a cataclysm."

Check out the clip in the video below.
