September asks December to bring an initiating reactor to complete the time machine. Then he meets Walter, Peter, Olivia and Astrid and explains how the device works. Peter finds a farewell video tape from Walter addressed to him. Olivia and Astrid go to December's apartment to bring the initiating reactor but they find him hanged and the part taken by Loyalists and The Observers. Astrid suggests to use an Observer shipping lane instead. Olivia and Peter go to the Observer's headquarters and use chemical gas to retrieve a control cube to use the shipping lane. They also rescue Broyles that was interrogated by Windmark. Now they start to set in motion the plan to defeat The Observers.

This is Fringe's 100th episode. See more
Earlier in the series we learned that Peter almost drowned in a car accident but was saved by "September". In this episode Peter and Olivia make sure that the "Observers" would never exist.
The last scene of the series show Peter and Olivia in a park with their baby. If the "Observers" never existed, it means that "September" could never have saved Peter from drowning and, if he could not have saved him, it means that Peter would have died in that car accident and would never have met Olivia.
