Autumn Cox, a character in the TV show “Manifest,” was a passenger on Flight 828 who worked with the Major to spy on the other passengers. She was eventually exposed and her fate after that is not explicitly shown in the series.
In the series, Autumn Cox is introduced as a seemingly innocent survivor of Flight 828, but it is later revealed that she has a more complicated background. She becomes a pivotal character in the first season when it is discovered that she is working with the Major, a shadowy figure with a keen interest in the passengers and the supernatural phenomena surrounding their return.
Autumn’s role is to gather information on the Stone family and report back to the Major. Her actions are driven by her desire to protect her daughter, as the Major has leverage over her. Despite her betrayal, Ben Stone eventually confronts Autumn and convinces her to help them against the Major. She provides critical information that helps the Stone family in their quest to uncover the truth behind the flight’s mysterious disappearance and return.
After her cooperation with the Stone family, Autumn’s storyline is not heavily focused on, and her character takes a backseat as the series progresses. The show does not provide a clear conclusion to her story, leaving her ultimate fate unresolved. As “Manifest” has multiple storylines and a large ensemble cast, some character arcs, including Autumn’s, are left with loose ends, especially since the show was initially canceled after its third season. However, it was later picked up by Netflix for a fourth and final season, which may or may not address her character further.
