Water thief

The Water Thief is, as his name suggests, a water thief in Vault 13 in 2161.

Interactions with the player character
This NPC is spawned during the Find the Water Thief quest.

When confronted, the Water Thief will give the same dialogue as "The Sleepy Vault Dweller", stating he had a nightmare and was worried about the Vault's water supply. When the player asks to search him the Water Thief becomes defensive and states he is innocent. Upon intimidation the Water Thief will oblige and the screen will go black, the Thief will be gone and the player will be rewarded for completing the quest.
