I was thinking the same thing. Although, vasectomies can be reversed and the urge to procreate is strong. If things worked out with Iris, I can see she and Eddie saying screw the future and still bringing a new Thawne into the world.
Nice catch. And Caitlyn isn't looking bad as KF. I approve.
But wouldn't that mean if the original timeline is in effect then Barry shouldn't be the Flash yet.
Hee!
I know some people hate to examine the ethical choices of our heroes but I have to point out how bothered I was that team Flash was on board with Barry going back in time. I mean even if they're comfortable with how altering the timeline will have an effect on countless others, then at least they should have stopped him from going back when they found out the additional risk of creating a black hole.
Even though Barry didn't save his mom, is it possible that his going back still created a butterfly effect?
