Us viewers (and Martin Stein) have been well aware of Ciscos powers for a little while now, but the rest of the S.T.A.R. Labs crew are totally unaware that their colleague has the ability to vibrate between timelines. Until now, that is. Harrison Wells is in the know, and so he proceeds to reveal Ciscos secret to the rest of the team, with the reasoning being so that they can track down Doctor Light. Arguably equally as WTF is the fact that Caitlin Snow isnt a meta-human. Of course, many were expecting Caitlin to ascend to the villainous (and meta-human) identity of Killer Frost. Still, Killer Frost looks likely to be a chilling presence over in Earth-2 at some point in the future.
