Wild Bill's Last Stand

 refers to an unmarked quest in the Fallout 3 DLC The Pitt.

Walkthrough
Milly, a slave in The Pitt's Downtown, is worried about Wild Bill who has been missing since going on an ingot expedition to the Steelyard, asking the player to look for him.

Wild Bill is found dead on a flight of stairs in the Steelyard. He carries his trusty Sidearm (a unique .32 Pistol), and a note explaining his fate. Next to him are several Steel Ingots.

Returning to Milly, you have several options. If you tell Milly that Bill is dead or lie and say he is alive, she will hand over six Stimpaks. If you complete a Speech check, you can convince her that you saw and heard him being torn apart by the Trogs, then had to put him out of his misery with an entire pistol magazine and a cinderblock to the head, you will cause Milly to faint in a humorous scene. She also appears to drop a stimpack upon fainting. However, upon fainting, it is likely for the ragdoll to spin around and fling the stimpack where you cannot see so quicksaving beforehand to make sure you can get it is advisable.

Reward

 * Wild Bill's Sidearm
 * 6 Stimpaks
