Lot of things happened from last week's episode of CW's [The Flash](series:1068303). Barry and Linda had a date, Barry and the gang tracked down and helped Dr. Martin Stein in Ronnie's body, Cisco helped Joe to investigate in Barry's old house, and Ronnie goes nuclear. And because of this episode I came up with a theory that Dr. Harrison Wells is Hunter Zolomon.
All of us already think that Harrison Wells is from the future and in my theory he is. It is revealed in one of the episodes that Harrison Wells is not handicapped and he's also a speedster known as the Reverse-Flash but actually he is truly handicapped.
Remember the episode "The Sound and The Fury" ? When Piper escaped, Harrison Wells run but he fell off and we can conclude that he is losing his energy because he is just charging using the device he stole. He can't walk on that scene because he truly is a handicapped.
In comics, Hunter Zolomon always use a staff so that he can walk easily because he is a handicapped person, Harrison Wells can't walk in the scene simply because he is Hunter Zolomon.
If you will be asking me why he is on his wheel chair when Barry found him it is because he still have some energy left but not enough to run fast.
Another theory is related to the death of Barry Allen's mother. Cisco Ramon and Detective West went to Barry's old house where the murder happened to investigate. Cisco cannot find any evidence using his "Super Light" device because he thought everything in the house were replaced but it is not because Joe saw a mirror in the photograph he is holding that it is there.
Cisco used his device to search for evidence in the mirror and he did found silver nitrates. Cisco told Joe that it came from the two speedsters and it can produce image of the night Barry's mother was murdered. They saw photos of Barry's mother with two speedsters and they also saw blood and they discovered that the blood were covered by a new wallpaper. Cisco got two different blood samples that came from the two speedsters.
One of the blood matches Barry's and Cisco told Joe about it. At first Joe ask if the blood belongs to Wells but Cisco told him that it do not belong to Wells instead it belongs to the Future Barry Allen.
It is said in that episode that there are two blood types that belongs to the two speedsters so if one of the blood belongs to the future Barry the other one belongs to? The answer is Dr. Harrison Wells. Cisco did not tell Joe who is the owner of the other blood it is because he can't match it to anyone. If he can't match it to anyone the person is not born yet. So the other speedster is from the future too and it might be Harrison Wells. Maybe Harrison Wells is faking his blood type in the present because he wants to hide his true identity. He cannot g back to the future because he is not that fast anymore to travel in time so he stole the tachyon device.
