User blog comment:Bo-Katan/Thawne and Time Remnants/@comment-27700324-20171203161527

Time Remnants are there to make time not fold in on itself. After Thawne is erased from existance, Barry and his friend's lives would be changed too much causing a paradox. The speed force fixes this by making a time remnant that lives the life of Harrison Wells so Barry and his friends still live their lives how they are supposed to. However after Flashpoint, Eobard was finally free from the circle of constantly having to be Harrison Wells. (He made a time remnant himself to do all that stuff though) So this second Eobard made the Legion of Doom and screwed with the Legends until the speed force saw this glitch in time and killed this second Eobard that isn't supposed to exist. Now we are at a point where Eobard created another time remnant just in case the Black Flash was following him, he ran to Earth-X where Thawne would be safe now that the Black Flash was dead. Now here we are.
