Actually, given what we have seen so far, it does make you wonder how much Isaac 'interefered' with the natural course of events.

Of course, the first question is when did Isaac take over in relation to the EF timeline. We know it was Dec 15, 1966 in our world, which is almost 50 years ago. If time is even CLOSE to the same, that would mean that everything we've seen (with the exception of the flashbacks from over 100 years ago with Ursula, Pan, Rumple, and Hook, Bae, etc) was part of Isaac's purvey. At least up to the point where he is trapped in the book, which is within a few months (at most) of when Regina cast the Dark Curse.
