Things have changed in the Arrowverse. Zoom appears, then Jay Garrick, then people from Earth-2. Wally West and Hunter Zolomon appears too. I have a theory that if Zoom's powers were drained by Barry, Barry loses control of the energy and it spreads everywhere, reviving Al Rothstein (E-1) and Eddie Thawne (making Eobard possible to exist), then zapping Jesse Quick, Wally West and Hunter Zolomon into a coma. They would wake in the third season, with Al gaining atomic powers and the rest of them speedster powers. Then, Jay Garrick would die and Hunter Zolomon will become the new Crimson Comet, Al Rothstein a good Atom-Smasher, Jesse Quick becoming like in the comics, and Wally West becoming Kid Flash. Meanwhile, Eddie wakes on a grassland, found out about the accident, and thought that everyone betrayed him, becoming the villain Cobalt Blue, who will be the main villain of the season. What about Zoom? He will become powerless but still a threat to Team Flash. This is only a theory by me.
