Manifest Season 4's age mystery surrounding Cal is related to the ongoing conflict with the 828 Registry. The department has arrested and imprisoned several passengers, which will worsen the situation.
The authorities' actions have put the passengers in a difficult position as they race against time to find a solution to the impending disaster.
The recent detention of Eagan, Saanvi, and Vance will further exacerbate the conflict between the Registry and the passengers.
Angelina's powers as an Omega Sapphire raise suspicions that she may be responsible for the impending volcanic cataclysm.
Cal may have an advantage in avoiding the Registry's pursuit due to his unidentifiable status as a passenger.
Cal's new identity as Gabriel Stone may make it easier for him to evade the Registry than the other passengers.
The divine consciousness may have increased Cal's age to give him the ability to outsmart the Registry and avoid capture.
The other passengers have recognized Cal's importance since season 1, and recent events have only reinforced this.
If Cal is captured, it could be the catalyst for the impending apocalypse.
