Find the Water Thief

Find the Water Thief is a side quest in Fallout.

Quick walkthrough

 * Return to Vault 13 after 30 days.
 * Speak to Lyle, Cindy, or the water guard about finding out who is stealing the water from the Vault.
 * Wait in the room near the elevator on level 3 until midnight.
 * When you see a lone Vault Dweller enter the water storage room confront him and insist that you search him.
 * Alternatively, you may kill the water thief for less experience.

Detailed walkthrough
After 30 days have passed since you left Vault 13 you will be able to return. 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.
