The Flash intro
Cisco is watching the teleprompter, "Alright, Barry, he's headed towards downtown! Hurry up before he detonates the entire building. " Barry/Flash was being cocky, running with a smile on his face, "I got this Cisco. " He jets towards the direction. Meanwhile, a bunch of armed men was shooting up in the air while people are screaming. The leader places bombs on each side of the corners. One of the armed men forcefully grabbed the woman and try to use her as a human shield. The police gets here, and fired some shots at the men. The leader shot some cops. The woman was crying, "Please don't hurt me; I have kids. "
Barry/Flash gets here to save the day. "Put the gun down, sir. " The leader looks around the perimeter, "Don't come any closer or she and everyone else in that will die!" "I know you're scared, but there is still hope for you, " Barry/Flash said. "Just please put down the gun. " The leader started crying, "They took everything away from me: My wife, my two daughters and my health!" Barry/Flash gets a little closer, "I'm so sorry about that, but there are innocent lives in that building, and if you push that button, there's no coming back from that. " He lowered the gun and let the woman go. Barry/Flash quickly took both the gun and the detonator. The police were arresting him. The bystanders were clapping their hands for the Flash, he waves at them and started smiling. He went back to S.T.A.R. Labs.
