Christine (Fallout: New Vegas)

Christine is a at first 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. However later she recovers her voice.

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, implying some sort of cybernetic modification.

Like the Courier, Christine was captured by Dog and forced to work for Elder Elijah in breaking into the Sierra Madre casino. At some point, she became trapped in a malfunctioning Auto-Doc, which tore out her vocal chords and caused her to lose her voice.

Endings
After the DLC is finished it is claimed that Christine stayed in the Sierra Madre as a "caretaker" thankful that the courier saved 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 afterwards, 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.
