Eddie Thawn shot himself and erased the entire Thawn bloodline, including Eobard. Therefore Eobard was never born and every event he participated in should have reset to exclude his existence. Except it wasn't. Now he traveled to the past and met the Flash for his first time despite never being born. Temporal mechanics in every show I've watched made sense until this.
