After watching this episode a few times, I came to a few different theories. Cisco stated that there were two different people. It wasn't JUST one.. In the episode we saw Reverse Flash beating up Dr.Wells which didn't make sense at all if he was Reverse Flash. Of course he probably was trying to make it seem as though he had nothing to do with Reverse Flash. I started contemplating if Dr. Wells had a twin. However, I realized that Reverse Flash began beating everyone up.............. except Eddie.
He simply stared at him and ran off.
