If you're hoping to get any clues to the action from The Flash Season 2 Episode 17 from the photos, don't hold your breath.

We will see some very welcome and familiar faces. Those of Eddie Thawne and Harrison Wells.
Sure, Harrison is still around by the look of him, but perhaps he'll have words of wisdom for our Barry. We can hope, right?
Check out the photos from "Flash Back" below and be here next Tuesday for a full review after the installment airs!
