Knight Torres

 is the Quartermaster of the Brotherhood of Steel armory in the Hidden Valley bunker.

Background
Torres has apparently lost a laser pistol, which can be found in the center of Scorpion Gulch, south east of Hidden Valley, on the rock right above the dead wastelander (who has a Sunset Sarsaparilla star bottle cap). Be careful, there are about 4 to 5 Giant Radscorpions in the area. If you complete the quest Eyesight to the Blind before finding the pistol for her she will no longer ask you about the lost laser pistol. (Note: Possible workaround: Try asking her twice.) The pistol in question will also be gone from the rock in Scorpion Gulch.

Additional notes for pistol quest: speak to the shooting range supervisor at the desk. If he is not at the desk he will be in the LOWER barracks in bed. Then go to speak to Initiate Stanton, he will either be in the class room or in the initiate barracks in bed. He will come clean about the pistol and tell you he was at the gulch.

Bugs

 * If you enter the bunker with all three mission holotapes, you encounter a bug wherein she won't sell anything to you, even after completing Still in the Dark and even Eyesight to the Blind. She'll only say she can't sell anything to outsiders, as per Elder's orders. See Forum:BoS quartermaster bug for more info.
