Dr. Harrison Wells
Dr. Harrison Wells is the man behind Central City’s S.T.A.R. Labs and the particle accelerator accident that grants Barry Allen his superhuman speed.
He now serves as a mentor to Barry, but is also keeping secrets from everyone on his team. Wells is not what he seems and has knowledge of the future. What is his true purpose and why does he keep a journal on Barry's progress?
None of us can stop, Barry. Fortunately, Felicity knows somebody who can. I think you better call back Oliver Queen. We're gonna need The Arrow's help.Harrison
Harrison: Felicity, I like to surround my team with known quantities. That is because I find the unknown to be toxic. Dangerous. Arrow is unknown.
Felicity: I can assure you, Dr. Wells, that he's not dangerous. To us.
