Speculation: TV Shows: The Flash - Henry Allen is Zoom?
This would be GREAT if Henry Allen was Zoom. Think about it...
What if on Earth 2, Barry Allen is the one in jail while Henry Allen is a speedster? Except that this speedster has time warping powers, just like the original Zoom in the comics. No speed force capabilities but just the ability to slow time down to a crawl, making it seem like he is moving really fast.
