I actually got a theory on how Eddie going to become the Reverse Flash. I been saying and predicting that they'll be TWO Zooms with Dr. Wells being Hunter Zolomon. With that, I going to believe that Eddie going to learn completely about Flash and become jealous of Iris' fascination of him. He's going to go to Dr. Wells OR Wells going to reach out to him and persuade him to take serum that he pulled from Blackout that made Flash lose his power and create Eddie to become the Reverse Flash. It's only a theory.
