who is eobold thawne to eddie thawne?
<answer> Eobard Thawn is the descendant of Eddie Thawne. <context> Detective Eddie Thawne is a police detective working alongside Detective Joe West. Eobard Thawn is the descendant of Eddie Thawne (Eobard Thawne is Reverse Flash / Harrison Wells and is also the Flash’s mentor and nemesis BTW) so basically, Eobard Thawne is from the future and got stuck during the present due to a lost battle with the Flash.
