You could make a reasonably fatal drinking game out of The Flash, based on these first three episodes: take a shot whenever Barry does some narration, a couple of fingers of your drink whenever there's a crack about speed, and down it whenever somebody mentions "metahumans". The last one is guaranteed to get you rat arsed, if not in an actual coma. Between the first couple of episodes no other superpowered people had made themselves known, but now they're cropping up all over the shop. Metahumans are like buses. You wait ages for one, then several turn up at once, and all of them have a new set of abilities with which to tear apart the city. That's what buses do, right? Expect to see plenty more of them throughout the series a fair amount of them have already been cast. Caitlin, that other STAR Labs member, shares a name with comic book villain Killer Frost; according to reports the first season will also feature bad guys like the metallic Girder, the explosive Plastique, and iconic Flash rogues Captain Cold and Heatwave.
