Episode two, entitled “Fastest Man Alive,” opens with Barry running around Central City in his awesome Flash costume. He’s doing heroic things, like rescuing people from a burning apartment building, with Cisco as support back at STAR Labs. It’s pretty great until Caitlin busts them. Caitlin is not happy about Barry heroing. At all. Dr. Wells isn’t keen on it either, but reminds Barry to know his limits, which is timely because we see Barry having some issues.
