“I mean that there are fewer loops than one might reasonably expect. I mean that sometimes we change the time line and then the time line seems to repair itself, in a way that doesn’t make sense to me. The course of history should be irrevocably altered every single time we travel back in the time line, but, well, it isn’t. Sometimes events seemingly change to accommodate the time traveler’s interference, so that a generation later it’s as if the traveler were never there.”
