Speed mirages or not, we know definitively that theres at least two versions of the Jay Garrick character running around. That's because we saw Zoom holding Jays body in his lair, meaning that one possible, if unlikely, reason for this is that theres cloning involved. Dont act like The Flash hasnt experimented with much more ridiculous concepts thus far, as cloning would seem to be both plausible and unexpected. It would explain Jay's lack of natural powers as well as his meek, inferior personality. Furthermore, it gives another explanation for why his cells are dying. But even if he were a clone, whos responsible for his existence? Perhaps Harrison Wells is more involved that hes let on and helped Zoom come about in order to stop The Flash on his Earth. It seems like an evil plan straight out of the Lex Luthor playbook, and while farfetched, that kind of reveal would absolutely explain most of the plot in a satisfying manner.
