Christine (Fallout: New Vegas)

Christine is a mute human prisoner trapped in the Sierra Madre in 2281. She is difficult to communicate with, and the player must have a high Perception or Intelligence in order to understand her properly.

Background
Little is known of Christine prior to the capture. It is, however, known that she used to be a Brotherhood of Steel Scribe, and that her baldness and facial scarring were not caused by the malfunctioning Auto-Doc. In fact, they were caused by Elder Elijah, who had captured her and forced cybernetic modifications upon her brain. She was rescued by Ulysses, and set out after Elijah in search of revenge.

It is later revealed that her time in the Big Empty was not the only reason she sought Elijah. She tells the player that he cut her off from her lover, who is implied to be Veronica.

Like the Courier, Christine was captured by Dog and God and forced to work for Elijah in breaking into the Sierra Madre Casino. At some point prior to the Courier's arrival, Dean Domino locked Christine in an Auto-Doc in the Villa's Medical District, programming it to alter her voice to that of Vera Keyes in order to gain access to the Sierra Madre's vault.

Endings
After the DLC is finished it is claimed that Christine stayed in the Sierra Madre as a "caretaker" (seemingly unable to 'let go') and was thankful to the Courier for saving her from Elijah. Over time the Ghost People came to see her as just another hologram.

Bugs

 * It is possible to initiate the first conversation with Christine without opening the auto-doc. You may open it afterward, but your character will be stuck in place and you will need to load a previous saved game to continue.

Appearances
Christine appears in the Fallout: New Vegas DLC, Dead Money.
