in time and between the two universes; the Fringe division finds evidence of Observers at several historical events but looking the same as they do in the present. Like September, the other Observers appear to be named after months, including "August" and "December". The episode "Inner Child" introduces the Fringe division to a child that appears to possess many Observer-like qualities. In the episode "Peter", September is a catalyst in Walter's abduction of Peter from the parallel universe; September arrived wanting to see the creation of the cure by Walternate that would have saved Peter, but instead distracted Walternate from witnessing a critical test result. When September saw Walter watching through the window-like device, he informed his fellow Observers that he could correct the situation; later, after Walter returned with young Peter to the prime universe and fell through the frozen lake's ice, September rescued them from the freezing water and told Walter, "The child must live". September and the other Observers have since monitored Walter and Peter. In the second season's finale, September is responsible for alerting the Fringe division to the dangers of Peter being taken back by Walternate to the parallel universe, ultimately leading to their rescue attempt. In the third-season episode "The Firefly", September conducts a convoluted experiment to test Walter's resolve to give up Peter for the greater good when the time comes. In the third-season finale, episode "The Day We Died", a gathering of ten Observers appeared on Liberty Island to watch and comment on the disappearance of Peter Bishop from existence. Later, he is ordered by his superior to ensure that Peter's status as nonexistent continues, and constructs a device to erase all lingering memories of Peter from Walter. However, at the last moment, he disobeys his orders and deactivates the device, allowing brief apparitions of Peter to appear to Walter and Olivia. In "Novation" Peter mysteriously appears in the new timeline. After being taken into custody by the Fringe Division, he learns that the point of divergence in the timeline is that September never saved him from drowning in Reiden Lake when Walter brought him over from the alternate universe. He also learns that, in the new timeline, the Fringe Division is unaware of the existence of the Observers. September later appears to Olivia while she waits for Peter and Lincoln to return from the alternate universe. Mysteriously wounded from a gunshot
