In addition to several set snapshots that surfaced this morning, new set photos from "The Flash" appear to reveal alternate-reality versions of Caitlin Snow (Danielle Panabaker) and Barry Allen (Grant Gustin) (YVR Shoots & Canadagraphs via ComicBookMovie.com). The new photos show Barry in a suit jacket and glasses with his hair parted neatly to the side -- something very different than his usual attire. More importantly, Caitlin is seen in her Killer Frost getup, which makes it seem as though Killer Frost's true debut is imminent.

If this Barry Allen and Caitlin Snow are indeed from Earth-2, it seems as though this world is an inverse of Earth-1; that is, those who were given metahuman abilities by the particle accelerator in Earth-1 were not in Earth-2 and vice versa, at least in most cases.
