I think Zoom on season 2 of Flash is going to be Eddie Thawne. If you notice Jay Garrick's helmet comes out of the worm hole and Eddies body goes in. Where ever he ends up he could be revived and become Zoom. He obviously has the same name as Eobard Thawne so I think it's a strong possibility. Why else would they have shown Eddies body get sucked in?
