Barry training against the drone and reversing the missile in mid air looked cool. The scene where Cisco demonstrated the shields for the police was good as well. Looks like Firestorm will actually have transmutation powers plus Jason Rusch shows up. I thought the Heat Wave and Captain Cold scenes were all pretty good. "You mean like Ghostbusters?" made me laugh. I like that Cold called Barry the Scarlet Speedster. Wasn't expecting Eddie to run out and protect the Flash. Nice Golden Glider tease at the end.
