Cisco (Carlos Valdes) has been on the case for a while now, but the next episode of “The Flash” will finally answer the big Ronnie Raymond (Robbie Amell) question. Episode 12 revealed that as a result of the particle accelerator explosion, Ronnie and Dr. Martin Stein (Victor Garber) are the same person. Now, the synopsis for episode 13, “The Nuclear Man,” reveals that Barry (Grant Gustin) will have to track down the split personality meta-human when he learns Ronnie poses a threat. Plus, the Flash has a new girlfriend now, so there’s that.

According to the synopsis for episode 13, Barry will go searching for Ronnie after realizing that Caitlin’s (Danielle Panabaker) now-meta-human fiancé has attacked an esteemed physicist. It may not be Ronnie behind the attack, however, even if it is his body. Episode 12 revealed that Ronnie and Dr. Martin Stein were fused into one person during a particle accelerator blast, and the promo for the new episode reveals that the S.T.A.R. Labs team will have some difficulty discerning which personality they are speaking with after they track down Ronnie.

Plus, after Barry’s hot date with new love interest Linda Park (Malese Jow) in the last episode, he will have to balance his burgeoning romance with his superhero alter ego. Also, Joe (Jesse Martin) brings Cisco in on his quest to clear Henry Allen’s (John Wesley Shipp) name and find out who really killed Barry’s mother.

Watch the promo for episode 13 below:

Will Barry be able to balance love with his Flash duties? Will Cisco be able to help Joe solve Nora Allen’s (Michelle Harrison) murder? Fans will have to wait to find out. “The Flash” airs Tuesdays at 8 p.m. EST on the CW.
