The examination of Cal’s future in Manifest season 4, part 1, prepared the foundation for the character to play a crucial position in the show’s concluding episodes. 

It has become clear throughout the course of the first three seasons that Cal is more connected to the Callings than any of the other passengers on Flight 828. 

The fourth and final season of Manifest began by answering some unanswered questions about Cal and his role in the overall plot.  

The most important query, of course, concerned his disappearance and abrupt aging in the season 3 finale. 

While Manifest refrained from giving all the answers, it did make some startling revelations regarding Ty Doran’s persona.  

Manifest provided some much-needed understanding about Cal’s connection to the Callings and what it is he is intended to perform throughout the course of a ten-episode tale.  

Cal appears to be considerably more crucial to the passengers’ future than they could have ever anticipated. 

Manifest Season 3’s brief mention of Henry Kim, a traveler on Flight 828, led to the first encounter with the Dragon.  

Henry claims that both he and Cal are Dragons. They are identifiable by a scar in the form of a dragon on their arms.  

In the climax, Olive came to the same conclusion when she said that Cal could save the planet.
