Who is Zoom?

Right now, I think that Henry Allen is a close candidate following by most likely Earth-2 Barry Allen. The body frame do seem more buffed on Zoom though--which makes Henry Allen my first choice.

This is what Henry said before leaving:
"When you need me, I will be here--but right now, Central City doesn't need you to be Henry Allen's son.

It needs you to be the Flash. My kid. The superhero.

I have to go.

I need you to tell me that it's okay."

They include this portion of the flashback which was from the first episode for some reason, the rest were just flashback of Barry getting destroyed by Zoom. I would say this is more of a coincidence which led to me thinking that Zoom is actually Henry Allen. That explains his sudden disappearance, or it could be a Earth-2 Henry Allen.

Seriously, if Henry Allen is Zoom--regardless of whether he is from Earth-2 it would be a really bad ass plot twist, and would that finally cause Barry Allen to fully break down mentally? We did see him become the Future Flash in the comics as a result of his past actions--which made him wanted to go back to the past to destroy his past self and correct the future the way it should have been. Or will Barry actually be Zoom himself of the future out to kill his past self?




I am unsure how that would go, as time travel and such is something really unpredictable, so both theories are still open to me. I would also like to hear what you guys out there actually think of my theories and what could actually work better for the current plot.
