Any fans of “Groundhog Day” the movie out there? It’s one of those movies that I somehow have to stop and watch whenever it shows up on TV. Tonight’s episode is the superhero version of that plot, and it works brilliantly here. Watch Nora as she tries to save everyone, and tries again, and again, and…you get the idea. It’s “Cause and XS” on THE FLASH! Want to know more? Follow us after the jump!
