This question already has an answer here:
This is a question about episode 4x16 of Fringe.
This episode, titled "Nothing as It Seems" takes place in the
alternate timeline, after the
return of Peter.
The episode begins with Marshall Bowman on a plane. The same scene occurs at the star of 1x13 ("The Transformation"). The events on the plane in the new timeline occur differently, in that
Bowman does not transform into a maniacal beast on the plane.
However, the same air hostess attends to Bowman and checks on him while his is in the washroom, and Bowman is seated next to exactly the same elderly passenger, despite a difference of three years. (The timeline has changed but not the date.)
It seems highly improbable that Peter's absence (the divergent event between the two timelines) should cause Bowman to make his flight (for the same purpose as the original flight) three years later than he did originally, and also highly improbable that three people with no connection to one another should appear again on the same flight (in particular, that Bowman and the same random passenger should be seated next to one another again, three years later).
Is this a plot hole, or is there a genuine in-universe cause for this highly improbable arrangement of events?
