Could this be the "ridiculous" look for Firestorm?
Robbie Amell, who plays Ronnie Raymond/Firestorm in The Flash, has posted a photo to his Facebook page, posing with Victor Garber, who plays Professor Stein, his mentor.
In the comics, Ronnie Raymond and Professor Stein were the first two people to share the body of Firestorm. Later, Luc Roderique was cast as Jason Rusch, who is the current "other half" of Firestorm.
You'll note that they're wearing the same outfit, likely an indication that Firestorm took the form of Professor Stein at some point, since thats not the clothes Ronnie was wearing the night he died (see right).
The Flash airs on Tuesday nights at 8 p.m. ET/PT on The CW. Ronnie Raymond has been teased as appearing in the midseason finale, "The Man in the Yellow Suit," airing December 9.
