WARNING: SPOILERS/NSFW - DC on SCREEN #145 - The Flash 2x17 - Flash Back | Review - The Flash is BACK! See what I did there? And so is Eobard Wells!  Barry is, despite advice from a very insistent Harry Wells, travelling back in time in hopes of tricking Harrison Wells (Eobard Thawne) into training him to be faster. Everything must be perfect! But of course, Barry screws it all up.  Before we know it, Time Wraiths are running rampant and Eobard knows that Barry is from the future! But it looks like this time excursion has some lasting effects on the current timeline...
