After hearing Donald/September explain the plan to get rid of the Observers, there's one nagging question on my mind: if the Observers were to no longer exist, wouldn't that mean September wouldn't be there to save Walter and Peter in the lake?
And September would not have distracted Walternate when he's trying to find the cure.
If Walternate isn't distracted, then Walter would have no reason to kidnap Peter who would then be cured and grow up in the alt universe. If he meets and has a child with altLivia, then their child would be Henry whose existence somehow prevents the Observer future.
(I'm hoping at some point for an explanation of how Henry would prevent the Observer future and yet Henrietta insures it.)
