I could have sworn it was said at one point that Sources start over after so long? Regardless, also consider that I'm not talking about specific outcomes, but I'm considering, for example, that three occurrences of D-day, despite the fact that D-day probably happened a bit differently in each universe, is still an occurrence if D-day. It's a beachhead invasion of Italy, just like the next beachhead invasion of Italy.

When you look at it in broad enough terms, the fact that so many similar occurrences happen is because there are only so many set patterns that events can follow. Start an empire? Been done. That empire falls? Also done. Saved lives in a warzone? Done many times. Lives- even the more exciting ones- run on parallels so much. At this point I'm having trouble expressing it in any deeper manner. Everything runs on parallels because when you disregard the more minute details, there isn't much else that even could happen.

I most certainly remember it being said that Sources go on until the path they follow is finished, and then they reset to do something different.
