5) Jay Garrick May Not Be Who He Says
All signs point to Jay Garrick being a good guy. Flashbacks have shown that he butted heads with Harrison Wells on Earth-2 about how best to deal with Zoom, but Jay’s story of being sent to Earth-1 after his nemesis stole his speed seems a little too convenient.
Why didn’t Zoom steal Barry’s speed before parading him around Central City? It looked like a simple enough procedure when he supposedly did it to Jay, and The Flash of Earth-2 deciding to make himself scarce as soon as Zoom made his first physical appearance in front of Team Flash is more than a little coincidental and odd.
What if Jay Garrick is Zoom then? It may seem ridiculously far-fetched, but there are certainly enough signs pointing to this being the case to at least acknowledge it as a very real possibility.
The Flash‘s producers have already said that they’re handling Zoom a lot differently to the comic books, and Jay’s grudge against Wells would certainly explain why Zoom has targeted his daughter. What Jay/Zoom is gaining from pretending to be powerless and working with Team Flash is a little harder to explain of course, but there’s definitely something about Jay which makes him hard to trust.
