Find Collar 12: Christine

 is a quest in the Fallout: New Vegas add-on Dead Money.

Objectives

 * 1) Find Christine at the Villa Clinic in the Sierra Madre Villa, and recruit her as a companion.

Overview
This quest is one of three given to the Courier after completing the quest Sierra Madre Grand Opening!. Speaking from the hologram fountain at the center of the Villa, Father Elijah instructs the player to recruit three companions, including Christine, in order to carry out a heist at the Sierra Madre Casino.
 * Note that the three quests (this one, Find Collar 8: "Dog" and Find Collar 14: Dean Domino) can be completed in any order.

Quick walkthrough

 * Head west from the hologram fountain and follow your Pip-Boy marker to the Medical District.
 * Once through the door, make your way to the Villa Clinic and go inside.
 * Turn off the shielded speaker blocking your way to Christine by using the terminal in the Clinic Basement.
 * Access to the basement can be gained by picking the lock (Lockpick 75), or by using the key located in a desk on the second floor.
 * Release Christine from the malfunctioning Auto-Doc, and recruit her to your team.

Detailed walkthrough

 * Heading west from the hologram fountain where you speak with Elijah, refer to your Pip-boy local map and make your way to the Medical District. Once you enter, Elijah will warn you about the speakers found in the area. There is one ahead of you, above an archway, which can be safely shot from a distance.
 * There are several Ghost People in the area. You can choose to fight them or carefully sneak past.
 * Go through the archways linking each open area. When you approach the archway with a toppled trash can in front of it, your collar will start to beep. Run straight to the closed door visible ahead. If you turn to face the way you came you will see the offending speaker high above the archway you ran through, and you can now safely destroy it.
 * The closed door hides a cloud-filled room. You can explore it now if you have enough health items to avoid death. Dean Domino's Unclean Living companion perk may prove useful here.
 * Continue following your map marker to the Villa clinic main entrance. You can also enter via the upper floor, by making your way through the nearby buildings, but note that this leads you past more speakers and puts you close to a Hologram guard in the clinic. Using the main entrance will give you a chance to get your bearings and collect some useful items before proceeding.
 * Entering the clinic (through either door) will prompt a further message from Elijah, warning about the holograms. There is a terminal near each entrance that contains further information and allows you to reprogram the hologram, which is patrolling the upper floor when you enter.
 * To deactivate the hologram you can disable (Repair 25) or destroy its emitter unit. This is located on the upper floor, on the wall halfway along the corridor. It glows bright blue and is easily visible. Use the terminal to set the patrol route to the lower floor, or simply stay out of view Hidden behind the hologram and follow it along the corridor until you reach the emitter. With the hologram gone, the only threat remaining in the clinic is the shielded speaker downstairs.
 * From the main entrance, to your left is one of Dean's secret stashes, and on the reception desk is the Stimpak vending machine code. There is a restroom behind the desk with a water source (irradiated). The left doorway leads upstairs.
 * Through the right doorway, a room to your right contains headless corpses, the Assassin suit, a Cosmic knife and a terminal with information that adds to the History's Sake challenge. The corridor straight ahead leads to the basement (to your left) and the other stairway leading upstairs (to your right). Down the corridor to your left is the shielded speaker which Elijah will advise you to disable.
 * The speaker terminal is down in the clinic basement past a locked door (Lockpick 75). You can find the key in one of the upstairs rooms in a desk (along with the Med-X vending machine code).
 * Also found in one of the upstairs rooms is the Mentats vending machine code, which you may find useful for various dialogue options and skill checks in the Sierra Madre (mentats add INT +2, PER +2, CHA +1). If you need them to talk to Christine (one check comes before leaving the clinic, needing one of the following: Science 60, Explosives 60, or Intelligence 5), you can go to the nearest vending machine and then return to the clinic to continue the quest.
 * Once in the basement, access the terminal to shut down the speaker, allowing you to safely reach Christine.
 * There is a workbench in this room, and on the shelf to the right of the terminal is a D.C. Journal of Internal Medicine.
 * Head back upstairs and return to the now deactivated speaker. Turn left and enter the end room, which contains a malfunctioning auto-doc. Activating this machine will release Christine, and after a short conversation in which you explain the situation, she will agree to join you. You can have her accompany you (if you have no other companion with you), or send her to wait at the fountain. Once this conversation ends the quest will be complete.
