-Hunter's father, James. He hates his father so there's motive. The military training is from the War of the Americas on Earth-2.

-Ronnie. So we don't know exactly what happens when you go through the singularity instead of the breaches but when Zolomon flew into the breach he ended up on Earth 1. But the evidence is for Zolomon's plan he wanted to replace what the team lost. A mentor for Barry, a friend or Cisco, and a love interest. So if  Zoom/Hunter wanted to replace what Caitlin lost, love, than he would have Ronnie stay dead to her. And this is the theory that makes the most sense with the "You wouldn't believe me if I told you."

- Honestly the evidence for Wally-2 that I've seen is not great but sure he was mentioned so sure I guess it's a possibility.

-You said Diggle which would be cool but I don't really see a motive. I think it would be cool though because of the iron Spartan mask on Earth1. (Also I guess Diggle-2 might not be in the military)

I really hope it's either Ronnie or James.
