Firestorm is coming to The Flash in "The Nuclear Man", and it sounds like he'll be the latest dangerous metahuman targeted by the Scarlet Speedster! Meanwhile, there are also details on Barry Allen's relationship with Linda Park, Nora Allen's murder case, and more. Check it out!

ROBBIE AMELL AND VICTOR GARBER GUEST STAR AS FIRESTORM — After Ronnie (Robbie Amell) attacks a physicist (Bill Dow), Barry (Grant Gustin) and the team realize they need to go after Caitlin’s (Danielle Panabaker) fiancé who is now a dangerous meta-human. They deduce the best way to track Ronnie is to find Dr. Martin Stein (guest star Victor Garber) who was working on a project called F.I.R.E.S.T.O.R.M. Barry struggles to balance his duties as The Flash and his relationship with Linda Park (Malese Jow), and Joe (Jesse L. Martin) enlists Cisco’s (Carlos Valdes) help to reinvestigate the murder of Nora Allen (Michelle Harrison). General Eiling (Clancy Brown) returns to Central City. Glen Winter directed the episode written by Andrew Kreisberg & Katherine Walczak.

I'm guessing that this will be the episode which finally sheds some light on what's going on with Firestorm, and wouldn't be surprised to see him ultimately suiting up as a member of Team Flash. We'll have to wait and see though. Elsewhere, there's still no mention of Reverse-Flash, but the investigation of Nora Allen's murder could lead to his return!
