The think season 5 will end with Hades making everyone face all the death the main cast has caused directly and indirectly. In the Underworld, Hades can take on the appearance / persona of people who have died because of the main cast's actions.

Most of the episodes will probably be centered on one member of the main cast having conversations with dead people and their role in the death(s). During each conversation, Hades has a chance to psychologically manipulate each one to either kill someone else, make them so guilt-ridden to commit suicide, or succumb to madness to never leave the Underworld.

When it seems like Hades is about to win, someone (Hook? King Arthur? Hercules?) will miraculously save them all and the next season's arc will be introduced.
