Often the word “hell” is used to express discontent or displeasure, and therefore, many consider it an abusive word. In other cases, it may be used to express disregard for conventional procedure and precautions.

The word “hell”: In Manifest, however, the context in which it has been used early in season 1 may point to something else. It not only signifies utter confusion, but one’s state of mind or being (i.e. “Turbulence” , the episode 3 title.) Although the common Christian concept of hell does not involve redemption, the writers may be using a more broad view of hell (i.e, a purgatorial view).
The word “fall”: The word “fall” or the action of falling may also be used by the writers in a similar manner (e.g. Kelly having fallen at the mall in episode 3, Jared taking the fall for Michaela in episode 4). One of the background songs used in episode 3 is “Hurt Fall” by Twisted Box. It is the lead song on their album “Goddess” (2013) which also contains songs titled, “Supernova”, “The Fallen Will Rise”, “Our Last Stand”, “Fight for Life”, and others.
In religion and folklore, Hell is an afterlife location, sometimes a place of torment and punishment. Religions with a linear divine history often depict hells as eternal destinations while religions with a cyclic history often depict a hell as an intermediary period between incarnations. Typically these traditions locate hell in another dimension or under the Earth's surface and often include entrances to Hell from the land of the living. Other afterlife destinations include Heaven, Purgatory, Paradise, and Limbo.
Other traditions, which do not conceive of the afterlife as a place of punishment or reward, merely describe Hell as an abode of the dead, the grave, a neutral place located under the surface of Earth (for example, see Sheol and Hades).
