After a lot of build up, "The Flash" is making good on its promise to bring Firestorm to the small screen in its upcoming episode, "The Nuclear Man."
The episode, which guest stars Victor Garber and Robbie Amell as Firestorm, tackles the fate of Dr. Martin Stein (Garber) and STAR Labs employee Robbie Raymond (Amell), who was also Caitlin Snow's (Danielle Panabaker) fiance. Meanwhile, Barry (Grant Gustin) struggles to balance his personal life and his secret super identity as the Flash. The episode also stars Malese Jow as Linda Park, Jesse L. Martin as Joe West and Carlos Valdes as Cisco, among others.
