The Flash returned last night with Barry more determined than ever to increase his speed in order to stop Zoom, who appeared to be their one-time ally, Jay Garrick. Having been trying to determine the right speed equation that would help increase the velocity of his run, Barry got an idea that sent him on a journey into the past.
Of course with any journey into the past, there are always complications, especially when he went to the time when they were dealing with Hartley Rathwaite, who had worked with Cisco and Harrison Wells before they knew him as Reverse-Flash. Barry also couldn’t help but be overcome with emotion when he saw Eddie Thawne, who had been alive at this point.
Then things only got even worse when a time wraith followed Barry along his journey, causing past Wells to realize he wasn’t who he claimed to be. It looked like Barry still needed to learn that messing with the past is never a good idea.
When the show returns on April 19, we will learn more about Zoom. Until next time, check out the top ten moments from “Flash Back.”
