Barry finds himself overwhelmed trying to do all he can to help as many people as he can as both the Flash and as a crime scene investigator. No matter how many he helps, he feels that there are others he is not there to help. This is proven when he stops to rescue people from a burning building, but that may cause him to arrive too late at a shoot-out at S.T.A.R. Labs between a rogue group called the Black Hole and police officers, including his friend Detective August Heart.
