You know how in movies where the future can be changed, as it is being changed, things slowly fade away?
Why slowly? What is taking time so along? The damage is done Should be just *poof* gone. Makes no sense.
Probabilistic circumstances allow for things to still maybe happen, like say you stop your parents during the exact sex session you were conceived, and they don’t resume until the next day, or next week, or even next year. You don’t disappear right away because there’s still a chance of you being made.
But if the change made is more definitive then it does reflect immediately, like if you went back and crushed your dad’s balls then you are an asshole, like what is wrong with you man? don’t crush a guy’s balls that’s rude. Oh, and you disappear immediately.
