Cause and XS

"Imagine this coffee cup is the space/time continuum. Whenever you go back in time, it breaks. Now, you can try and reset the timeline, try and fix it, but no matter how hard you try, it's never gonna be exactly how it was. It seems like things worked out this time, but that's not always gonna be true, and it's impossible to know how these changes are gonna unfold, the ripples you'll cause, whose life you're gonna affect. No one can do that. No one? No one. We're not gods, Nora. We've just been given extraordinary abilities."

- Barry Allen and Nora West-Allen
