Christine (Fallout: New Vegas)

Christine Royce is a mute human prisoner trapped in the Sierra Madre in 2281.

Background
She is a member of the Circle of Steel, a splinter faction of the Brotherhood of Steel dedicated to taking a more active stance in the wasteland. She was a scribe in the Brotherhood of Steel before joining the Circle of Steel at the rank of knight. During her life in California, she was in love with Veronica Santangelo, however, due to Elijah's intervention the two were separated: Santangelo transferred to the Mojave chapter, while Royce joined the Circle.

When Elijah abandoned the Brotherhood after the disastrous Operation: Sunburst, he left a trail of crimes across the wasteland. As word of these crimes reached the Circle, Christine was dispatched to track him down. She managed to locate him in the Big MT. However, once she confronted her mark at Little Yangtze, they were interrupted by security robots. The Elder escaped using the ghoulified Chinese prisoners as walking bombs while Royce was wounded and taken to the Y-17 medical facility for processing. During the course of experiments at the facility (involving jamming electrodes into the skull), her brain was damaged to the point of her losing the ability to read and write words properly (although she can still do equations and math).

It was there that she was rescued by Ulysses, who blew up part of the facility just to get her out. She recuperated with him for several days at Ulysses' Point, where they discussed philosophy and the failure of modern civilizations like the NCR or the Legion to forge a new future. Once Ulysses met the think tanks and received his answers, the two separated. Christine left Big Mountain with the Mark I stealth suit and resumed her quest to find Elijah. Her original armor and rifle were left behind.

She eventually tracked him to the Sierra Madre Casino, where she was captured by his slave Dog and forced to work for him in breaking into the Sierra Madre with an explosive collar. At some point, she was also locked in an Auto-Doc in the Villa's Medical District by Dean Domino, where her vocal cords were torn out. She later regains use of her voice when the operation is completed by the Auto-Doc in Vera Keyes' hotel room, where it is revealed that her capture was part of Domino's plan to break into the Sierra Madre Casino Vault, as the elevator could only be activated by the voice of the long-dead Keyes.

Quests

 * Find Collar 12: Christine: The player has to travel to the Villa Clinic to find her. Once inside the player has to release her and take her to the fountain in front of the Sierra Madre.
 * Mixed Signals: The player has to escort Christine to the Puesta del Sol switching station to get her ready for her part of the Trigger the Gala Event quest.
 * Last Luxuries: The player has to find, and confront, Christine in the Sierra Madre Casino.
 * Heist of the Centuries: Christine can use her new voice to unlock the elevator to the Sierra Madre Vault.

Other interactions

 * When the player travels with Christine, she will be able to block out radio signals for a short time. She will also increase the amount of time taken for the collar to detonate.
 * She knows how to counterfeit Sierra Madre chips, and can give the player the Coin Operator perk with the right dialogue options.

Endings

 * If Christine completes her mission, she finds new purpose as the Sierra Madre's warden. She watches over it silently - by choice. Over time, the Ghost People come to see her as one of the Holograms. They watch, silently, as she walks among them. At times, Christine thinks of the Courier, who had kept Elijah's hand from her throat. The Courier had reminded her of the other courier she had met in the Big Empty, and wonders if the two had found each other at last. She does not think of them again until she hears the legends of the Divide. The Divide, where the two messengers, the two couriers, fight beneath an ancient flag, at the edge of the world.
 * If Christine is scared by her hunt for Elijah and unable to let him go, she perishes in the Sierra Madre Casino. She never completes her mission, nor does she stop to consider what had made her accept the mission in the first place. Obsession is another form of greed, a lesson that Christine never learned.

Notable quotes

 * "The quick Scribe jumps over the lazy Paladin."
 * "Love makes people do strange things. Won't argue that. It can drive you crazy sometimes if you can't... connect."

Appearances
Christine Royce appears in the Fallout: New Vegas add-ons Dead Moneyand in Old World Blues, Christine, like Ulysses, doesn't physically appear but her voice does appear in three audio logs.

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. Using 3rd person view, you are able to peek into the auto-doc and initiate dialog with Christine before opening the door. Once the door is finally opened, the bug occurs.
 * If you have Dean Domino or Dog/God as a companion, the camera may center directly through his head (or chest) during the first bit of dialogue with Christine.
