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?
Have to agree with both you and Darth Pipes on this, that is indeed a bit of a conundrum. It's the same damn thing that bugged me when Peter went into the machine and created the bridge between the universes. If that action caused Peter to never have existed, then how in the bloody name of Hell could the machine have been activated, since it was keyed to Peter, and ONLY Peter.
I suppose this is one of those things we're not supposed to think too hard about.
