This is Fringe's 100th episode. See more
The point of going to the future is to stop the forced evolution of the Observers. Walter and Michael make it to the future and the show ends with the Observers' invasion never happening because the Observers never happened, or at least not in the emotionless form we saw in the show. If that is the case, then September should not have been present at the Lake to save Peter and Walter, so both of them should be dead. Also, if September never existed, then Michael never existed. So the invasion would still take place. What we should have at the end is Olivia, without Walter, joining Fringe Division and researching the Plan (an idea dropped early in Season 1). But of course, we could go back as long as the Observers have been observed in history (the historical prints and paintings shown throughout the series). So it is possible that none of this would ever have happened and we could be looking at a completely different time line. See more
It's not about fate, Walter. Yours or mine. It's about changing fate. It's about hope. And protecting our children.
