So, these guys being heroes and all that, they aren't just going to leave Zoom as Earth-2's problem, they're going to travel there and stop him once and for all. There's just one problem with that. Every time Zoom and Barry have ben in the same room, it's been evident that the Earth-2 speedster could lay a major beatdown on the Flash whenever he wanted, throwing him around like a rag-doll. How on Earth, 1 or 2, are Team Flash going to stop him? Presumably they will, because the heroes need to win in the end, but right now it looks like an impossible task.
