I am new to the whole Flash story, but I need help understanding something regarding the Flash and Reverse Flash. So if Eobard Thawne is a distant relative to Eddie, does that mean Barry doesn't age? Because from the looks of it Eobard Thawne is a bit older and from a further future. I mean, surely in the timeline Eobard is from Barry should be dead of old age?
The Reverse Flash even said that Cisco has been dead for centuries to him. Could someone explain this for me?
