Prisoner

Prisoner is a mysterious character found in a locked cell while Girl is traveling through the Prison. They appear bald, and have their eyes bandaged. They will plead for Girl's help while also exclaiming to stay away. When girl unlocks the prison doors in order to escape, Prisoner's door will be open. If Girl enters Prisoner's cell she will attempt to help, but Prisoner will tackle her and bite her neck, killing her. When Girl leaves the Prison, she will express her desire to help but chooses to wait for Stranger's advice. After Girl returns from the Ritual Chamber, she will have a conversation with Stranger. During it, she will ask Stranger about Prisoner, but Stranger denies having any knowledge of them. If Girl enters the Prison again, Prisoner will have vanished.

Notepad.pnga and Speculation

 * A character that highly resembles Prisoner appears in the event, "Rat in the Trap II".
 * It is possible that Prisoner is a member of the cult. It is more likely, however, a version of Girl.
 * There are many hints as to the nature of Prisoner. From these, a possible timeline of events can be produced.
 * A version of Girl, Prisoner, experiences Bad End I. During this, she refuses to give in and thus has both of her eyes gouged out. After this happens she either gives in, or Stranger gives up to find another version of Girl to use. This could explain why Prisoner kills Girl when given the chance.
 * The events of the event "Rat in the Trap I" happen. Dialogue in this event closely resembles Bad End I, with the main difference being that the character talking will mention that their eyes are itchy. This is in contrast to Bad End I where Girl only mentions that her one eye is itchy.
 * Prisoner gets locked within the prison. It is possible a version of Stranger does this, or Prisoner simply finds their way there. While trapped, their form becomes decrepit and unrecognizable.
 * Girl, while traveling through the Prison, notices Prisoner but decides against helping them until she can get information from Stranger.
 * The events of "Rat in the Trap II" happen, where a character resembling Prisoner succumbs to the mansion's curse and transforms into a monster. Prisoner's final thoughts are of her sister.
 * While Girl is exploring the Ritual Chamber, Stranger finds and kills the former Prisoner. Their body is stuffed in a crate on the Second floor foyer, found later by Girl.
