The show is doing that, not me. I'm only pointing it out.Why do you keep making things far more ambiguous than they actually are?
How can Harry know he created him? Was he there? Why hasn't he told them who he is? It may be simpler, but it's far more boring. It also kinda opens that question up. Harrison hasn't seemed to react to anyone really. Why are they making it such a mystery. At this point, there are few characters that would justify it taking so long to reveal his identity. I also don't know how him sending Earth-2 metas after Barry equals he's from Earth-2. I don't know why he's fixated on Earth-2 either really. His character seems to just be blank. We first see him through Jay's flashback-story though, which I'm not even sure we can trust now.Literally every single thing we know about Zoom is associated directly with Earth-2 (E2 Wells says he created him, we first see him on Earth-2, he's been menacing Earth-2 for 2 years, he keeps sending Earth-2 metas after Barry, etc.). The simplest explanation, therefore, is that he's an Earth-2 native.
God bless you! God bless everyone!
