The cast of The CW's The Flash is already hard at work on the second season and happily sharing behind-the-scenes snaps from the set.

Grant Gustin and Carlos Valdes say adios to their facial hair as it is time to get to work. Gustin captures old pals Wentworth Miller and Dominic Purcell chatting it up. On-Screen adversaries Gustin and Tom Cavanagh get along just fine behind-the-scenes. Candice Patton catches her two co-stars goofing off. Firestorm actors Robbie Amell and Victor Garber heat up a cast photo.

Check out the images below.
