Has anyone tinkered with the idea of Wells being future Barry Allen? Thats one possibility. They look alike. Wells is willing to kill to protect Barry. Has intimate knowledge of the future. One possible theory.
Current Wells is Barry Allen. He attempts to go back in time to save his mother. Reverse Flash follows, which causes the altercation. young barry enters the room, future barry saves young barry( as we have seen) by moving him to the street, thus allowing his mother to die at the Hands of RF and the Flash path to be set.
What if there was another fight off screen after the fight in the house? The fight ends with Reverse flash being the victor, and Future Barry Allen trapped in the past timeline, powerless and unable to return. We all know based of the convo with Det. West that Wells showed up in Central city the day after Barry's mom was killed? Anyways, Future Barry changes his identity to H. Wells ( H.G. Wells, time machine inventor anyone?), disguises himself in the wheelchair and as a professor(easy to do since he has intimate knowledge of the future and future tech), and awaits the 14 years it takes young Barry to grow and ultimately become the guy that he can mold as a better Flash moving forward.
Why is he in possession of the suit? Because without the creation of the suit, and reverse Flash, there would be no murder, no Flash period...
If this theory holds true, he will eventually give this suit to Eddie Thawne, who will take on the role of Reverse Flash. Thawne already has a hate for the flash, and insecurities about Barry due to his relationship with Iris. The love triangle has been set in motion. Once Iris and Eddie both connect that Barry is the Flash, which is inevitable, thats gonna change everyone. Something big will happen. Eddie will have even more reason to hate the Flash and Barry Allen. Adding to this is we also know that RF spared Eddie's life, and this was bought out by Eddie in the show.. Also judging by the end of the episode, the person in the suit may not necessarily be meta. That tachyion device apears to give the suit powers, so the person wearing it may not naturally have powers..
