- It all occurred to me while watching Justice League Doom. One of the villains happens to be a master of illusion, deception and hologram generation ( If you have not watched the movie please do ) , Mirror Master.
My theory is that Dr Wells is Mirror Master And he impersonated the reverse flash using that weird machine at the end of Episode 8 after he goes into his secret room and activates the yellow suit. I believe that he created a hologram and placed that in the suit thus allowing him to be present in various places and aided in beating himself up, this also helped him keep his secret from Cisco and Caitlin. Well he did all this to gain Barrys trust while learning his secrets.
