Detailed walkthrough
On January 5, 2162, the player is once again able to enter Vault 13. To receive this quest they need to speak to one of the following people in the Vault:


 * Lyle located on the second level, second room from the left of the screen on the south side.
 * Cindy located on the second level, first room from the right of the screen on the south side.
 * The Water Guard located on level 3, outside the storeroom door.

After speaking to any of these people about the water thief enter the room nearest the elevator on level three and rest there until midnight. Once you are done resting you should see a lone Vault Dweller entering the water storage room (the room with multiple lockers containing Vault 13 canteens). When he exits the room confront him and insist that he let you search him; note that you must pass a Charisma check, or he will simply attack. After you handle the situation you will be fast traveled to the Vault 13 officer and earn 1000 experience, or 500 experience if you kill the water thief in the process.

Reward
The amount of experience varies based on how you handle the situation.
 * 1000 experience points for ending the matter peacefully.
 * 500 experience points if you kill the water thief.
