When we last saw Robbie Amell's Ronnie Raymond in The Flash, he had seemingly sacrificed himself to close the Singularity above Central City. However, does the photo below prove that he survived and has become the Firestorm of Earth-2? That's certainly one possibility - especially if he tracked down Earth-2's Jason Rusch - though it's equally as likely that this IS the Earth-2 version of Ronnie. We'll have to wait until this episode (which is going to feature Team Flash travelling to Earth-2) airs to find out, but feel free to share your thoughts and theories on this in the comments section.
