Check Out the Extended Promo for the Mid-Season Finale of The Flash

The CW has released an extended promo for the upcoming mid-season finale of The Flash. Airing tomorrow, December 8, the episode is called, “Running to Stand Still” and will feature the introduction of Wally West.

I really really hope we get a scene with Wally, Barry and Jay Garrick. How cool would it be to have three Flashes in one scene together! I would freak!

Are you excited for the show’s mid-season finale?
