User blog comment:Kaestal/My theory of Savitar being the Arrowverse version of Cobalt Blue (And therefore Eddie Thawne)/@comment-27673963-20170414150925/@comment-27700324-20170415012851

There is alternate ways the story played out, but those are alternate earths. Savitar knows Barry though. He has constantly fought him and hated him. It makes no sense if he is Barry. That is like if you waged a war on TheDoctor950 from E-2 for no reason.
