Have a think about what you said for a second.......... Still don't get it? Ok I'll explain for you.... Eddie killed himself, there fore Eobard is never born, so you are correct that it affects the future...BUT Eobard went back in time and killed Wells etc... SO it DOES affect the past also.... If Eobard is never born, he never goes back in time, and never kills Harrison Wells, therefore Wells is still alive... Sooo maybe get your facts straight before you have a go at others hey?
