A nice way to use knowledge from Peter's (and now Olivia's) original timeline. How many shows have such an opportunity?
We needed to see Olivia complete her journey to original Olivia. And we needed to see other's questions this (the FBI, Lincoln). For Olivia, fitting back into this world could not be made to be easy.
The only one question I have is, why did these events happen so much later (a few years?) in the show's timeline because of the Peter change? In other words, why didn't this happen in their 'series 1', why was it the same flight? These are not important questions, just curiosities.
Perhaps, this is tell us that Peter's impact is greater than just Walter and Olivia.......
