"The Flash" hits its midseason finale tonight, and The CW has released a new clip that emphasizes the series' ever-expanding world of metahumans. The one-minute clip details the return of Robbie Amell as Ronnie Raymond -- but it's not the same character that appeared during early episode flashbacks. Delivering the full scene of Ronnie declaring his new identity of Firestorm, the clip sees Caitlin Snow (Danielle Panabaker) and Cisco Ramon (Carlos Valdes) exploring tunnels to find Ronnie, only to discover that he's got some newfound qualities that may make him far more difficult to bring back to S.T.A.R. Labs.

"The Man In the Yellow Suit," the midseason finale of "The Flash," airs tonight on The CW.
