Two weeks ago we learned that Jay Garrick's doppleganger on Earth 1 was Hunter Zolomon. Since then, a lot of theories came up along with the new information, which includes, the inevitable theory of Zolomon being the Zoom.
On the image above, you can see a side-by-side eye comparsion with Zoom and Teddy Sears (Jay Garrick). The results seems very comparable, even more if you pay attention to the perfect-matching extension of his eye bag. We can't be sure if Zolomon really is Zoom, but we all can agree that there was always something off about Jay Garrick. Does he know that Zolomon is Zoom? Or is him connected with Zoom somehow beyond what he told the Team Flash? I guess we'll have to wait a few more weeks to discover it on TV.
